Subject: [PATCH 0003/1424] [Testing] Add MPS to NATIVE_DEVICES (#153835)

This would allow me to enable more opinfo tests against MPS device eventually and supposed to be a very simple test, but actually required minor adjustments to lots of test files, namely:
- Introduce `all_mps_types_and` that is very similar to `all_types_and`, but skips `float64`
- Decorate lots of tests with `@dtypesIfMPS(*all_mps_types())`
- Skip `test_from_dlpack_noncontinguous` as it currently crashes (need to be fixed)
- Add lots of `expectedFailureIfMPS`
- Delete all `@onlyNativeDeviceTypesAnd("mps")`

&lt;sarcasm&gt; I love how well documented this variable are &lt;/sarcasm&gt;

Subject: [PATCH 0006/1424] Fix inductor memory estimation when a single buf
 has multiple mutations. Add runtime verification of mem tracking (#159569)

With fsdp, we sometimes have multiple, non-overlapping views of a single buffer which are all mutated. Previously we considered the original buffer as an allocation, and make the mutated buffer the deallocation. With multiple mutations of the same buffer, we need to consider the original buffer as deallocated only when all of its aliases die (and avoid double counting the input buffer size). See comment inline:

```
    When an operation mutates a buffer in-place, the scheduler creates a new buffer name
    to track the "before" and "after" states, even though they share the same memory.
    The mutated buffer represents a rename with zero allocation and deallocation cost.
    During dependency tracking, we transfer dependencies from the mutated name back to
    the original buffer, ensuring the original memory is only freed when all aliases
    are done.
    This handles cases where a buffer has multiple non-overlapping aliases - rather than
    trying to assign free costs to individual aliases, we forward all alias dependencies
    to the original buffer.
    Consider:
        buf0 = op0()
        buf1 = mutation_op_(buf0)
        del buf0
        ...
        op(buf1)
        del buf1
    The only memory events are the creation prior to op0, and the deletion following buf1.
```

As @IvanKobzarev 's logs in https://github.com/pytorch/pytorch/pull/158361/files#diff-e173a1d52aff49959c9f6d17ecc09946d8a616fc5909df884e62a15e1ebd1d41R1776-R1807 show, it can a bit of a pain to pinpoint which part of our memory calculation is incorrect.

This pr also adds a runtime verifier `config.test_configs.track_memory_lifecycle` which tracks buffer allocation and deallocation, and errors if their lifetime does not match our expectations.

+    When an operation mutates a buffer in-place, the scheduler creates a new buffer name
+    to track the "before" and "after" states, even though they share the same memory.
+
+    The mutated buffer represents a rename with zero allocation and deallocation cost.
+    During dependency tracking, we transfer dependencies from the mutated name back to
+    the original buffer, ensuring the original memory is only freed when all aliases
+    are done.
+
+    This handles cases where a buffer has multiple non-overlapping aliases - rather than
+    trying to assign free costs to individual aliases, we forward all alias dependencies
+    to the original buffer.
+
+    Consider:
+        buf0 = op0()
+        buf1 = mutation_op_(buf0)
+        del buf0
+        ...

Subject: [PATCH 0007/1424] [BE] Update TensorPipe pin (#159834)

No functional changes, just:
- Update C++ standard to C++17
- Update `cmake` min version to 3.18
- Update `libuv` dependency to 1.51 (to move its cmake min version to 3.10)
- Replace boost optional implementation with `std::optional` wrapper
- Make it compilable with gcc-14.x plus by including `cstddef` in few headers
-  Avoid using deprecated enums for MacOS builds

Subject: [PATCH 0009/1424] [ez][CI] Remove some unused docker images (#159171)

Removes unused docker images from the docker build workflow
Then removes unused definitions in build.sh

The only one I left is the vllm one because I'm pretty sure it's going to be used in the future

I assume everything not mentioned is old and we forgot to remove them

Subject: [PATCH 0011/1424] [autograd] torch._C._set_view_replay_enabled state
 leaking into other tests (#159840)

This was causing view_fns to pop up in tests that ran after `TestAutograd.test_view_replay_enabled` where it isn't used as a context manager. It is unclear to me why we would want `_force_original_view_tracking` to mutate global state on __init__ rather than on __enter__, that could be an alternative fix.

Subject: [PATCH 0014/1424] [Inductor] Revert minimal changes to avoid internal
 test failures (#159809)

The diff/PR https://github.com/pytorch/pytorch/pull/159211 caused a bunch of test failures for graph compiler(T232684410). But I couldn't figure out a forward fix so far. So with this diff/PR, I'm proposing to revert the minimal changes to resolve the test failures.

I'll continue the debugging, and re-land the reverted changes once we find out a forward fix.

Subject: [PATCH 0016/1424] [export] Improve error messages (#159881)

Originally, if the PT2 errored when loading, we would try to load using the old loader to fit BC issues. However this hides the error messages for if an up-to-date PT2 is erroring when loading due to some other reason.

Subject: [PATCH 0019/1424] Set PYTHONHOME for inductor subprocesses using
 torch (#159382)

Summary:
This is needed for subprocesses that are trying to call back into torch
functionality, i.e. anything that's also setting `PYTHONPATH`.  There are more
`sys.executable` subprocesses in torch/ but it seems like they're fine.

Test Plan: Local inference runs.

Subject: [PATCH 0020/1424] fix logging setup issue for Windows.. (#159887)

When we setup logging config as guide: https://docs.pytorch.org/docs/stable/logging.html
Such as:
    TORCH_LOGS="+schedule,+inductor,+output_code"
On Linux, it shows as:
```cmd
declare -x SSH_TTY="/dev/pts/0"
declare -x TERM="xterm"
declare -x TORCH_LOGS="+schedule,+inductor,+output_code"
declare -x USER="xu"
```
On Windows, it shows as:
```cmd
TORCHINDUCTOR_WINDOWS_TESTS=1
TORCH_LOGS="+schedule,+inductor,+output_code"
UCRTVersion=10.0.22000.0
```
For Linux, it shows quotes by default, And Windows is not shows quotes.
Besides that, Windows would auto assemble quotes when env var processing.

On Linux, we will get variable: "+schedule,+inductor,+output_code"
On Windows, we will get variable: '"+schedule,+inductor,+output_code"'

So, we need remove the outer quotes for Windows.

Subject: [PATCH 0021/1424] [Take 2] Setup TorchBench in Docker  (#159300)

Fix and reland https://github.com/pytorch/pytorch/pull/158613, I keep `checkout_install_torchbench` in `.ci/pytorch/macos-test.sh` script because it's still used there, and there is no Docker.

### Testing

MacOS perf nightly run https://github.com/pytorch/pytorch/actions/runs/16580798470

Subject: [PATCH 0026/1424] Add DeviceAllocator as the base device allocator
 (#138222)

# Motivation
In line with [RFC] [A device-agnostic Python device memory related API design for stream-based accelerators](https://github.com/pytorch/pytorch/issues/134978), some memory-related APIs are widely used in popular repositories, such as HuggingFace [so many if-else conditional code](https://github.com/search?q=repo%3Ahuggingface%2Faccelerate%20torch.cuda.empty_cache&type=code). We would like to introduce a generic API set under torch.accelerator namespace to generalize these user cases.

# Solution
This design follows a similar pattern to `HostAllocator`. We're introducing a base class `DeviceAllocator`, from which `CUDAAllocator` and `XPUAllocator` will inherit. This allows us to provide a unified call path like: `torch.accelerator.empty_cache()` -> `GetDeviceAllocator(allocator)->empty_cache()`.

+
+    Core statistics:
+
+    - ``"allocated.{all,large_pool,small_pool}.{current,peak,allocated,freed}"``:
+      number of allocation requests received by the memory allocator.

+    - ``allocated``: historical total increase in this metric.

Subject: [PATCH 0030/1424] [Torch Package] Make get names of OrderedImporters
 support fallback to importers (#155743)

Summary:
OrderedImporters is supposed to be an importer which tries out every single importer in self._importers. However the get_name API does not follow this behavior and only uses the get_name from the basic Importer class.
This change is to update the OrderedImporters get_name API so that it tries the get_name API of every single importers.

Subject: [PATCH 0031/1424] Enable fr_trace to read local traces from multiple
 hosts. (#159490)

Summary: For training jobs particularly from GenAI, NCCL trace dumps are generated in the format of `<hostname>.pci3_rank_<rank>`. For multi-node training jobs, the hostname varies across traces. The current prefix matching logic can't handle this case.

Test Plan:
Create a local folder `dumps` and several empty files: `host0.pci3_rank_0`, `host0.pci3_rank_1`, `host1.pci3_rank_0`, `host1.pci3_rank_1` inside it. Then run
```
buck2 run fbcode//caffe2/fb/flight_recorder:fr_trace -- trace_dir dumps
```

Before this diff, fr_trace cannot locate any trace files, giving the following assertion error:
```
AssertionError: no files loaded from /home/tianhaoh/dumps with prefix pci3_rank_
```

After this diff, fr_trace is able to locate the trace files, resulting in the exceptions like
```
    dump = pickle.load(infile)
           ^^^^^^^^^^^^^^^^^^^
EOFError: Ran out of input
```
(since the trace files are fake and empty).

Rollback Plan:

Subject: [PATCH 0041/1424] [AIDIR] Internal util function to insert MLHub
 debugging insight for dynamic shape (#159391)

Summary:
This feature is Meta internal only
Add a util function to put dynamic shape-related suggestion to MLHubDebugInsightService, which will then be surfaced to users in the MLHub .

The rollout will be controlled by JK.

Test Plan:

MAST job aps-omnifmv3_dev_baseline_test-a34fdccf21

 {F1980593060}

* If you're not able to see the insight, please add yourself to this gk 'mlhub_debugging_insights_dev_visibility'
* The URL link should route to a new Job Inspector page that will provide details and straight forward instructions of how to config the ds. The page is currently still in development so here we use the general PT2 compile JI page.
* Test fails because of the export checks. I'll export after addressing all the comments from reviewers.

Rollback Plan:

Subject: [PATCH 0045/1424] [aoti][mps] Initialize mps kernels first (#159753)

In some cases we have mps kernels which are reused across higher-order-op subgraphs and the toplevel code. However, currently we initialize the variable for the mps kernel the first time we use it, which runs into an issue if we run into the mps kernel within a subgraph since the kernel will only be initialized within the subgraph scope. For instance:
```
if ...
    auto mps_lib_0_func = ...
    mps_lib_0_func->run()

// since we already used mps_lib_0 once, we don't re-initialize it
mps_lib_0_func->run()  // error, mps_lib_0_func not initialized
```

So the solution we took here is to initialize all the kernels at the beginning:
```
const std::shared_ptr<at::native::mps::MetalKernelFunction> get_mps_lib_0() {
    static const auto func = mps_lib_0.getKernelFunction("generated_kernel");
    return func;
}
AOTIMetalKernelFunctionHandle get_mps_lib_0_handle() {
    static const auto handle = AOTIMetalKernelFunctionHandle(get_mps_lib_0().get());
    return handle;
}
...
if ...
    get_mps_lib_0()->run()

get_mps_lib_0()->run()  // success
```

Subject: [PATCH 0046/1424] [WOQ] Add CUDA kernel for _weight_int8pack_mm
 (#159325)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Summary**
This issue proposes implementing a CUDA kernel for aten._weight_int8pack_mm, a weight-only quantized (WOQ) linear operation that is currently only supported on CPU. On CUDA, the fallback path uses an unfused .mul().sum() pattern in quantization.py, which is less efficient for inference. https://github.com/pytorch/pytorch/issues/158849

**Motivation**
A fused GPU kernel for aten._weight_int8pack_mm would:
- Eliminate reliance on the .mul().sum() fallback in quantization.py
- Improve performance for quantized inference on CUDA
- Extend Inductor’s GPU quantization support across more workloads

**Implementation**
- Implement a Triton kernel for:
```
out[b, n] = sum_k(x[b, k] * w[n, k]) * scale[n]

where:
x: [B, K] float32
w: [N, K] int8
scale: [N] float32
out: [B, N] float32
```
- Integrate the kernel with register_woq_mm_ops() in torch/_inductor/quantized_lowerings.py
- Route it conditionally in quantization.py where GPU currently falls back to .mul().sum()
- Add unit tests comparing results to the reference fallback path

Test Plan:
```
buck2 run 'fbcode//mode/opt' :linalg test_linalg.TestLinalgCUDA.test__int8_mm_m_64_k_64_n_64_compile_True_slice_True_cuda
```
Log: P1882799769

```
buck2 test 'fbcode//mode/opt' caffe2/test:linalg
```
https://www.internalfb.com/intern/testinfra/testconsole/testrun/6755399722424741/

Subject: [PATCH 0047/1424] [OpenReg] Disable automatic inclusion of data files
 (#159845)

# Background

After I built torch_openreg, I noticed that the wheel package contained the stub.c file under the csrc directory, which was not used in the runtime.

# Motivation

This PR aims to remove the stub.c file and any unused file when running torch_openreg.

**Changes:**

- Setting **include_package_data** keyword to false in the setup function

Subject: [PATCH 0050/1424] [precompile] Skip serializing unnecesssary objects
 for guards. (#158926)

Summary:
The following type of objects don't need to be serialized for precompile:
1. PyCapsule because we don't guard on C binding objects in meaningful ways.
2. Code object because we only id matching on these but id matches will always be dropped for precompile.
3. Nested function objects since we also ban CLOSURE_MATCH.

Test Plan:
buck run mode/opt test/dynamo:test_dynamo -- -k test_skipped_objects

Rollback Plan:

Subject: [PATCH 0052/1424] [AOTI] Add more default options to
 compile_standalone (#158560)

Summary: When compiling for standalone, make embed_kernel_binary and emit_multi_arch_kernel default to True, and add a default name for model_name_for_generated_files to make the generated cpp project easier to understand. Also improved the weights object file naming to be more readable.

Subject: [PATCH 0053/1424] [DCP][Prototype] Checkpoint replication via
 PGTransport (#157963) (#159801)

Summary:

### PR Context

Introduce simple replication logic via PGTransport. The goal is to showcase a working prototype of replication via PGTransport, in this impl we assume world_sizes are equal allowing us to create perfect bi-directional pairs for the purpose of choosing replica "partners".

Test Plan:
CI

Rollback Plan:

Subject: [PATCH 0054/1424] [async-TP] Make scaled-mm + reduce-scatter preserve
 alignment of scales (#159957)

After https://github.com/pytorch/pytorch/pull/157905 started using cuBLAS for row-wise scaling on CUDA 12.9+, this broke some downstream tests for fp8 which were testing "odd" shapes. After checking in with the cuBLAS team this turned out to be due to the scale tensors' starting addresses not being aligned to 16 bytes. PyTorch storages are always aligned at 256 bytes, hence this came from a "slicing" of the scale tensor being done inside async-TP when chunking a matmul in order to overlap it with reduce-scatter.

Subject: [PATCH 0055/1424] Fix execution frame cleanup logic (#158717)

Summary: This fixes a bug in the execution fram cleanup logic - previously, whenever we hit the time interval to clear out the frames, we were removing any cached execution frames beyond the configured minimum number (frameEntry.used was unused). Instead, we only want to clear frames that were NOT USED in during the last time interval. This diff refactors the executor to have the correct logic.

Test Plan:
```
buck2 test 'mode/dev-nosan' fbcode//sigmoid/inference/test_gpu:model_runner_test -- ModelRunnerTest.Basic_InterpreterCuda_Multithread_Cleanup --run-disabled --print-passing-details
```

Rollback Plan:

Subject: [PATCH 0056/1424] [AOTI] Fix memory leak from all_reduce (#159818)

Summary: This PR solves two issues:

1. When lowering the all_reduce op, Inductor expects to convert it to the in-place version, all_reduce_, but it was calling ir._AllReduceKernel.create_inplace instead of ir._AllReduce_Kernel.create_inplace. This triggers a tricky bug in AOIT because it generates cpp call to the functional version aoti_torch_cpu__c10d_functional_all_reduce, but later corresponding wait operation will still wait on the input to aoti_torch_cpu__c10d_functional_all_reduce instead of the output from aoti_torch_cpu__c10d_functional_all_reduce. This causes unwaited tensor leading to memory leak.

2. Since AOTI generates the inplace version aoti_torch_cpu__c10d_functional_all_reduce_ now. The return tensor from aoti_torch_cpu__c10d_functional_all_reduce_ doesn't get used. It will be released when the program exists, so it's not a memory leak but it will unnecessarily hold that tensor which causes high memory water mark. This PR generates tensor delete operation right after calling aoti_torch_cpu__c10d_functional_all_reduce_.

Subject: [PATCH 0059/1424] [inductor] add _get_inductor_debug_symbol_cflags
 for debug symbol control. (#159938)

We need to add inductor debug symbol support for crash case debug. When we turn on generate debug symbol.
On Windows, it should create a [module_name].pdb file. It helps debug by WinDBG.
On Linux, it should create some debug sections in binary file.

I added UT for it also.

It works well on Windows inductor debug.

Subject: [PATCH 0062/1424] [BE] Merge 3 CUDA build jobs into one (#159890)

Before this change there were build+test jobs:
 - s89 build+tests
 -  sm75 build+distributed_test
 - sm_75 build+pr_time_benchmark test
This change compiles all 3 builds into one (for 2 architectures) and skips testing sm86 as it never found any new regressions that were not found at the same time on sm89

Subject: [PATCH 0064/1424] Add minimal nn.functional.log_softmax support for
 NestedTensor (#159662)

This only works for the jagged layout and for the non-batch and non-jagged dimensions.

I did this mostly by copy-pasting from the existing softmax implementation, but it seems fairly straightforward and I think it should work.

**Summary**
Add macros for brgemm, so that callers (e.g., Torchao's cpp kernels) know which APIs are available. It is useful when callers need to co-work with old versions of PyTorch.

Subject: [PATCH 0068/1424] [inductor][ez] fixup scaled_mm (#159948)

Summary:

This reverts the part of #159383 for scaled_mm where now, like before,
we pass through the normal input_nodes (not the triton_input_nodes)
to select_algorithm

- #159383 refactored how kwargs are retrieved
- it introduced this notion of KernelInputs that wrap input_nodes
- scaled_mm uses unsqueezed input nodes for triton to retrieve params
- the issue: it uses a squeezed (regular) bias for select_algorithm
  instead

This fixes that by passing the original input nodes rather
than the triton input nodes.

Test Plan:

```
buck test '@fbcode//mode/opt' fbcode//caffe2/test/inductor:fp8 -- --exact 'caffe2/test/inductor:fp8 - test_rowwise_scaling_shape_1024,1024,512_has_bias_True_use_fast_accum_True_persistent_matmul_False (caffe2.test.inductor.test_fp8.TestFP8Lowering)'
buck test '@fbcode//mode/opt' fbcode//caffe2/test/inductor:fp8 -- --exact 'caffe2/test/inductor:fp8 - test_rowwise_scaling_shape_1024,1024,512_has_bias_True_use_fast_accum_True_persistent_matmul_True (caffe2.test.inductor.test_fp8.TestFP8Lowering)'
```

This set of tests was failing, and is passing now

Side note: these tests were failing I believe because the unsqueezed
bias made the ATEN choice no longer eligible, and there is some minor
numerical discrepancy between ATEN and Triton for this. I'm not sure
the test should be written like that, as we're implicitly relying on
ATEN being the choice here.

Subject: [PATCH 0074/1424] gloo: fix building system gloo with CUDA/HIP
 (#146637)

Fix incorrect linking of Gloo's libraries when building with system Gloo. Previously, either Gloo's native library or Gloo's CUDA library were linked. However, Gloo had changed such that all users of Gloo must link the native library, and can optionally link the CUDA or HIP library for Gloo + CUDA/HIP support.
This had been updated when building/linking with vendored Gloo, but not when using system Gloo.

Fixes: #146239

Subject: [PATCH 0081/1424] [Profiler] Fix unexpected C return events (#159574)

The fix in https://github.com/pytorch/pytorch/pull/155446 addressed the "stack empty" issue that's easily reproducible on CPython 3.12.0-4. While this issue can also appear in other versions, it's not as easy to reproduce there.

I recently found a new cause for this problem.

https://github.com/python/cpython/blob/1df5d0014578be7fe7ae25e2cc60c50c8b5cc0f7/Python/ceval.c#L5807-L5836

In the CPython 3.10 implementation, PyTrace_C_CALL and PyTrace_C_RETURN/PyTrace_C_EXCEPTION are supposed to appear in pairs. However, when c_profilefunc is changed, unexpected PyTrace_C_RETURN/PyTrace_C_EXCEPTION events can occur.

Here is the code to reproduce this problem.

```
import threading
import time
import torch

from threading import Event, Lock

lock = Lock()
lock.acquire()

event1 = Event()
event2 = Event()
event3 = Event()

def run():
    event1.set()
    event2.wait()
    lock.acquire()
    event3.set()

threading.Thread(target=run).start()

with torch.profiler.profile(activities=[torch.profiler.ProfilerActivity.CPU], with_stack=True):
    event1.wait()
    event2.set()
    time.sleep(1)

with torch.profiler.profile(activities=[torch.profiler.ProfilerActivity.CPU], with_stack=True):
    lock.release()
    event3.wait()
```

<img width="1766" height="1250" alt="image" src="https://github.com/user-attachments/assets/6794eeca-7364-429e-91eb-62cdad116bd3" />

To fix this problem, we can record active_frames_ and remaining_start_frames_ for each thread, and when the PyTrace_C-RETURN/PyTrace_CEXT CEPTION event occurs, we can determine whether to record this event based on these two fields.

In reality, even without this fix, the final data appears to be right since the match process can handle this case (it would just result in an exception log being printed).

Do you think the fix is necessary?

Subject: [PATCH 0083/1424] [Dynamo] Add torch.xpu.stream to trace rules
 (#159844)

# Motivation
Previously, I thought using `with stream:` was sufficient. However, many older scripts still use `torch.xpu.stream` as the context manager. To maintain backward compatibility, I had to include `torch.xpu.stream` in the trace rules.

Subject: [PATCH 0084/1424] Add a USE_NIGHTLY option to setup.py (#159965)

If you run python setup.py develop with USE_NIGHTLY, instead of actually building PyTorch we will just go ahead and download the corresponding nightly version you specified and dump its binaries. This is intended to obsolete tools/nightly.py. There's some UX polish for detecting what the latest nightly is if you pass in a blank string. I only tested on OS X.

Coded with claude code.

-"""Script to build split pytorch wheels
-
-What is split build / why is it important?
-    > Split build is splitting the PyTorch build into a libtorch &
-    > PyTorch python frontend package. This allows us to to publish
-    > both as separate packages and opens up our ability to have users
-    > install different libtorch backends per their PyTorch frontend
-    >
-    > Example: opening up the door to things like:
-    >     pip install torch[cuda]
-    >     pip install torch[rocm]
-    >     pip install torch[cpu]
-    >     etc.
-
-Why does this exist?
-    > Currently our split build requires you to invoke setup.py twice
-    > Which ends up complicating the build process and adds some level
-    > of complexity to our setup.py / build invocation for split builds.
-    > Ideally this script will eventually not be needed but for
-    > development purposes we should have an easy way to invoke this script

Subject: [PATCH 0086/1424] Move smoke binary builds to 3.12 (#159993)

And limit them just to stable CUDA version (as there weren't any recent instances when only one of those jobs failed to build)
Pull Request resolved: https://github.com/pytorch/pytorch/pull/159993
Approved by: https://github.com/ngimel

Subject: [PATCH 0087/1424] Relax unclaimed successes in dtype op tests when
 running under TEST_WITH_DYNAMO/TEST_WITH_INDUCTOR (#159976)

This PR changes the behavior for compile wrapped op tests:
- supported_but_unclaimed_forward
- supported_but_unclaimed_backward

These typically manifest when the op doesn't support inputs of certain dtypes. But under torch.compile, Dynamo/AOTAutograd will trace the graph with FakeTensors, which @ezyang and @eellison tell me need to run decomps before op dispatch. The decomp may map this test to a different op, one that does support the dtype. I suspect all of our failures here are due to decomps, and so I propose to just disable this check for compile.

~~TODO: re-enable all the failed tests.~~ jk there were no failed tests outside of compiled autograd due to this.

Subject: [PATCH 0088/1424] Make onnx export SDPA match aten behavior (#159973)

This PR makes onnx sdpa export match the behavior of aten sdpa when boolean mask is used.
@justinchuby

```python
import onnxruntime as ort
import torch

class ScaledDotProductAttention(torch.nn.Module):
    def forward(self, query, key, value, attn_mask):
        return torch.nn.functional.scaled_dot_product_attention(query, key, value, attn_mask=attn_mask)

model = ScaledDotProductAttention()
attn_mask = torch.ones(2, 4, 8, 8).bool()  # boolean mask for attention
attn_mask[0, 0, 0, :] = False  # masking an entire row (padding token)
query = key = value = torch.randn(2, 4, 8, 16)
output = model(query, key, value, attn_mask)

torch.onnx.export(
    model,
    (query, key, value, attn_mask),
    "scaled_dot_product_attention.onnx",
    input_names=["query", "key", "value", "attn_mask"],
    output_names=["output"],
    dynamo=false, # or True,
)
ort_session = ort.InferenceSession("scaled_dot_product_attention.onnx")

np_inputs = {"query": query.numpy(), "key": key.numpy(), "value": value.numpy(), "attn_mask": attn_mask.numpy()}
onnx_outputs = ort_session.run(None, np_inputs)[0]

torch.testing.assert_close(output, torch.tensor(onnx_outputs), equal_nan=True)
```
fails the assertion because the ort model outputs nans.

Subject: [PATCH 0091/1424] [inductor] [cpu] fix the dype hardcoded to int64 in
 store_reduction (#157904)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Fixes https://github.com/pytorch/pytorch/issues/157683

## mini repro
* Just copy the code from the issue to reproduce it.
```python
import torch

device = "cpu"

# Input tensors
v2_0 = torch.randn(16, 24, 59, dtype=torch.complex64, device=device)
v3_0 = torch.randn(16, 24, 59, dtype=torch.complex64, device=device)

def my_model(v2_0, v3_0):
    v6_0 = -v3_0
    v4_0 = v2_0 * v3_0
    v1_0 = v4_0.unsqueeze(-1).unsqueeze(-1).unsqueeze(-1).unsqueeze(-1)
    v0_0 = v2_0.to(torch.int32)
    v5_0 = v0_0.amax(dim=0)

    return v6_0, v4_0, v1_0, v0_0, v5_0

v6_0, v4_0, v1_0, v0_0, v5_0 = my_model(v2_0, v3_0)
print("v6_0", v6_0.shape)
print("v4_0", v4_0.shape)

compiled_model = torch.compile(my_model, backend="inductor")

v6_0, v4_0, v1_0, v0_0, v5_0 = compiled_model(v2_0, v3_0)

print("v6_0", v6_0.shape)
print("v4_0", v4_0.shape)
print("v1_0", v1_0.shape)
print("v0_0", v0_0.shape)

```
## summary
**The C++ kernel generated by the Inductor had the wrong data type for the output variable; it should be int32_t instead of int64_t. This incorrect data type led to an incompatible data type conversion, which caused the g++ compilation to fail.**
The original code that caused the problem.

```
so the following line have problem
```c++
    // this line means that tmp_acc0_vec should be Vectorized<int64_t>, and it will convert it to Vectorized<int32_t>.
    auto int32_t_tmp_acc0_vec = at::vec::convert<int32_t,1,int64_t,2>(tmp_acc0_vec);
```
The issue is that tmp_acc0_vec is of type Vectorized<int32_t>, but the template parameters expect it to be Vectorized<int64_t>.  and it will convert it to a Vectorized<int32_t>. this is conflict. the conversion should not be exist for tmp_acc0_vec is already Vectorized<int32_t>.The following line hardcodes the output variable type to int64, which causes unnecessary and incorrect type conversions.

Subject: [PATCH 0093/1424] Remove benchmark dependencies from regular ROCm CI
 images (#160047)

Instead, use a new `pytorch-linux-jammy-rocm-n-py3-benchmarks` image for Docker benchmark job.  This addresses 2 issues:

* The current ROCm failures in trunk w.r.t librosa version https://github.com/pytorch/pytorch/actions/runs/16789466749/job/47549950994 that TorchBench pulls in.
* Reduce the size of the regular ROCm CI images by removing TorchBench models, which is needed only for benchmarking jobs.

Subject: [PATCH 0096/1424] [nativert] Expose ModelRunner to public through
 pmpl type ModelRunnerHandle. (#159989)

Summary:
Today users outside of pytorch core cannot `#include <torch/nativert/ModelRunner.h>`.

It turns out that we should place a header inside `torch/csrc/api/include/`. Placing every single nativert header here would pollute the namespace a lot and that's not what we want in general. Therefore here we just create a Handle type which hold a pointer to decouple the actual type from header definition.

Test Plan:
CI

Rollback Plan:

Subject: [PATCH 0100/1424] [DTensor] support _StridedShard in view op
 (#159656)

**Summary**
Some thoughts on view-op and `_StridedShard` interaction:
1. `_StridedShard` has no impact on sharding (i.e. how tensor is partitioned)
compared to `Shard`. It only changes how shards permute across the devices.
2. `view()` op on DTensor strictly forbids shard redistribution which means if
`view()` may cause shard permutation across devices, it should be rejected.
This is enforced in today's sharding prop for `view()`.
3. Since DTensor `view()` won't introduce any redistribution, it's certain that
`placements` won't change except the inner `dim` attribute of `Shard`
or `_StridedShard`.

Therefore, to support `_StridedShard` in `view()` op, the only change required
is to keep `_StridedShard` as `_StridedShard` in the output spec.

**Test**
`pytest test/distributed/tensor/test_view_ops.py`

Subject: [PATCH 0101/1424] Move xla jobs to unstable workflow (#159272)

Disables the job on PRs completely, so that we don't litter people's CI signals and use machines unnecessarily.

If you want to run these xla tests, add the ciflow/unstable label to your PR

-

-

-    - ``peak``: maximum value of this metric.
-    - ``allocated``: historical total increase in this metric.

-
-    In addition to the core statistics, we also provide some simple event
-    counters:

Subject: [PATCH 0104/1424] Revert "Add DeviceAllocator as the base device
 allocator (#138222)"

This reverts commit f7a66da5f9f6b8b75119b1ee8ce9ddc23e15570e.

Reverted https://github.com/pytorch/pytorch/pull/138222 on behalf of https://github.com/jithunnair-amd due to Broke ROCm periodic runs on MI300 e.g. https://github.com/pytorch/pytorch/actions/runs/16764977800/job/47470050573 ([comment](https://github.com/pytorch/pytorch/pull/138222#issuecomment-3164941815))

-## Collection and Post-Processing ##
+## Torch Operation Collection ##
+This section describes the general flow for collecting torch operations during auto-trace (in-process, synchronous tracing). For details on on-demand tracing (out-of-process, asynchronous), please refer to the Libkineto README.
+
+When a trace begins, the autograd/profiler backend calls into `profiler_kineto.cpp` to prepare, start, or stop collection. At the start of tracing, the `onFunctionEnter` and `onFunctionExit` callbacks defined in `profiler_kineto.cpp` are registered.
+
+Callback registration can be either global or local, depending on the `ExperimentalConfig` used:
+- **Global:** The callback is registered to all threads throughout execution.
+- **Local:** The callback is registered only to threads present *at the start* of tracing.
+Within `onFunctionEnter`, the profiler creates a `ThreadLocalSubqueue` instance for each thread, ensuring that each CPU operation is associated with the thread on which it was executed. When a torch operation is entered, the profiler calls `begin_op` (defined in `collection.cpp`) to record the necessary information. The `begin_op` routine is intentionally lightweight, as it is on the "hot path" during profiling. Excessive overhead here would distort the profile and reduce its usefulness. Therefore, only minimal information is collected during the callback; most logic occurs during post-processing.
 
-TODO
+## Allocation Event Collection ##
+
+Unlike torch operations, which have a start and stop, allocation events are represented as `cpu_instant_event` (zero duration). As a result, `RecordFunction` is bypassed for these events. Instead, `emplace_allocation_event` is called directly to enqueue the event into the appropriate `ThreadLocalSubqueue`.
 
 ## Kineto Integration ##
 
-TODO
+Kineto serves as an abstraction layer for collecting events across multiple architectures. It interacts with libraries such as CUPTI to receive GPU and accelerator events, which are then forwarded to the frontend profiler. Kineto requires time to "prepare" (also referred to as "warmup") these third-party modules to avoid distorting the profile with initialization routines. While this could theoretically be done at job startup, keeping a heavy library like CUPTI running unnecessarily introduces significant overhead.
+As previously mentioned, `profiler_kineto.cpp` is used in the backend to invoke the appropriate profiler stage. It also calls into `kineto_shim.cpp`, which triggers the corresponding routines in Kineto. Once a trace is complete, all events collected by Kineto are forwarded to the profiler for two main reasons:
+1. To coalesce all data and complete any post-processing between profiler and Kineto events.
+2. To forward these events to the Python frontend as `FunctionEvents`.
+The final step in integration is file export. After all events have been collected and post-processed, they can be exported to a JSON file for visualization in Perfetto or Chrome Tracer. This is done by calling Kineto's `ActivityTraceInterface::save`, which writes all event information to disk.
 
 ## Python Tracing ##
 
-TODO
+When `with_stack=True` is set in the profiler, the Python stack tracer is generated using the `make` function defined in `PythonTracerBase`. The implementation resides in `profiler_python.cpp`.
+To profile the stack, `PyEval_SetProfile` is used to trace and handle various execution events within a Python program. This enables comprehensive profiling by monitoring and responding to specific cases:
+- **Python Function Calls (`PyTrace_CALL`):** The `recordPyCall` method logs each Python function call, capturing essential details for later analysis.
+- **C Function Calls (`PyTrace_C_CALL`):** The `recordCCall` method documents calls to C functions, including relevant arguments, providing a complete view of the program's execution flow.
+- **Python Function Returns (`PyTrace_RETURN`):** Exit times of Python functions are recorded, enabling precise measurement of function execution durations.
+- **C Function Returns and Exceptions (`PyTrace_C_RETURN` and `PyTrace_C_EXCEPTION`):** Exit times for C functions are tracked, whether they conclude normally or due to an exception, ensuring all execution paths are accounted for.
+This setup allows for detailed and accurate data collection on both Python and C function executions, facilitating thorough post-processing and analysis. After profiling, the accumulated event stacks are processed to match entrances and exits, constructing complete events for further analysis by the profiler.
+**Note:** For Python 3.12.0–3.12.4, a bug in CPython requires the use of `sys.monitoring` as a workaround.
+
+## Clock Alignment ##
+
+Depending on the system environment, the profiler will use the most efficient clock when creating a timestamp. The default for most Linux systems is TSC, which records time in the form of CPU cycles. To convert from this time to the unix time in nanoseconds, we create a clock converter. If Kineto is included in the profiler, this converter will also be passed into Kineto as well to ensure alignment.

Subject: [PATCH 0110/1424] HF component update to not use fsspec components
 (#159405)

Update HF components to not inherit from fsspec components and instead use filesystem writer/reader. The reason is because there doesn't seem to be much of a need for fsspec, since users are using mounted storage. Using local storage will allow for performance improvements because we can take advantage of the safe_open API provided by HF safetensors (30s vs 4s for load of 8b model), which is signifcant performance wins over reading bytes and converting to tensors which is what we are doing now. Also, we can use the official methods provided by HF instead of relying on reading the metadata by bytes and loading it

 bytes (#159406)

Reading the bytes and converting to tensors is much slower than using safe_open. For a 8B model across 8 ranks, took ~30s to load before this change and ~4s after.

Subject: [PATCH 0112/1424] Use only safetensors APIs in HFStorageReader
 (#159681)

Get rid of the logic to read the metadata from the header of the safetensors file manually and use the functions as part of safe_open() to get the metadata. This is much cleaner and allows us to not rely on our own custom methods to get metadata, but use safetensors provided APIs

Subject: [PATCH 0116/1424] [DTensor] Support user-supplied Generator for
 random ops (#159933)

If the user provides a generator kwarg to a random op (e.g.
nn.init.uniform_(..., generator=my_generator)), we can still advance
that generator's state in a SPMD-global way so that each local-tensor
gets appropriate values and the generator advances to the same state as
if it had operated on the full tensor.

Subject: [PATCH 0117/1424] [export] Apply move_to_device_pass to all
 submodules (#159992)

Previously we only applied this move_to_device_pass to the toplevel graph. However if we have HOO, this pass will not be applied on the HOO submodules. This PR modifies the pass to run on all submodules.

Subject: [PATCH 0120/1424] [MTIA] Allow users who know what they are doing to
 ignore all device mismatches in tracing and take a preferred device.
 (#159931)

Summary:
Device mismatches in tracing can most often be ignored. These are only logical mismatches not physical.

Take any intermediate computation, and that computation will not actually materialize in a compiled binary execution. So a device mismatch in the middle of the program is not real. The runtime will never materialize those tensors on CPU device during the execution, as they are temporary allocations.

If a user knows his tensors at graph input are all on the correct device, then he can ignore all tracing errors.

Users who know what they are doing should have an escape hatch to ignore any device mismatch in tracing.

Users can set
```
  torch._functorch.config.fake_tensor_prefer_device_type = 'mtia'
```
to forcefully override any mismatch and prefer the non cpu device. This unblocks vLLM graph mode for MTIA.

Test Plan:
Added two unit tests.

Rollback Plan:

Subject: [PATCH 0124/1424] Log max_autotune exceptions (#159687) (#159688)

Summary:

Exceptions during autotune kernel precompilation are now systematically captured and reported via the chromium_event_logger, enabling better debugging and analysis of autotune failures.

Currently, exceptions are dumped to the console in the following format::
```
[0/0] RuntimeError: No valid triton configs. OutOfMemoryError: out of resource: triton_mm Required: 262144 Hardware limit:232448 Reducing block sizes or `num_stages` may help.
[0/0] Runtime error during autotuning:
[0/0] No valid triton configs. OutOfMemoryError: out of resource: triton_mm Required: 262144 Hardware limit:232448 Reducing block sizes or `num_stages` may help..
[0/0] Ignoring this choice.
```

The exception tracebacks:
```

    raise RuntimeError(f"No valid triton configs. {type(exc).__name__}: {exc}")
```

With this change, the exception details will also be logged in the metadata of the `{name}_template_precompiling` event.

The format:
```
{
  "exceptions": [
    {
      "choice_type": "triton",
      "choice": "ACC_TYPE='tl.float32', ALLOW_TF32=False, BLOCK_K=128, BLOCK_M=64, BLOCK_N=64, EVEN_K=True, GROUP_M=8, USE_FAST_ACCUM=False, num_stages=5, num_warps=4, num_consumer_groups=0, num_buffers_warp_spec=0",
      "exception_message": "No valid triton configs. OutOfMemoryError: out of resource: triton_mm Required: 262144 Hardware limit:232448 Reducing block sizes or `num_stages` may help.",
      "exception": "OutOfMemoryError",
      "required_memory": "262144",
      "hardware_limit": "232448"
    }
  ]
}
```

Subject: [PATCH 0126/1424] integrate kernacle into inductor (#160121)

This adds integration into inductor in two parts

1) It kicks off the best config lookup at lowering time within mm.py
2) It awaits the future at scheduling time in select_algorithm.py

Notably this does not do the following

1) Support for enumerating between mm, addmm and bmm
2) Support for enumerating between exhaustive/max
3) Enumerating different hardware SKUs eg. H100, A100, etc.

those will come in the next diffs

Subject: [PATCH 0127/1424] Fix infinite loop when iterating over an empty zip
 (#159673)

Dynamo would enter in an infinite recursion when
`ZipVariable.next_variable(tx)` was called and there was no iterable to
be iterated

Subject: [PATCH 0128/1424] [BE]: ruff PLC0207 - use maxsplit kwarg (#160107)

Automatically replaces split with rsplit when relevant and only performs the split up to the first ( or last value). This allows early return of the split function and improve efficiency.

Subject: [PATCH 0133/1424] [SymmMem] Use _get_default_group() instead of
 group.WORLD for group_name access (#158718)

Both approaches functionally return the default process group created by `init_process_group()` but `_get_default_group()` is a dedicated function with [better error handling and type safety](https://github.com/pytorch/pytorch/blob/4869f7117009fb99a57482fce56b00c6163fbce6/torch/distributed/distributed_c10d.py#L1300-L1310).

Subject: [PATCH 0134/1424] [SymmMem]  Standardize NVSHMEM Triton wrappers on
 byte-based APIs + improve code clarity (#159136)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Quick refactor for consistency and clarity.

1. We now standardize all NVSHMEM data-moving collectives (put, get, alltoall, broadcast) to use their byte-based *_mem_block variants. This makes the API behavior more predictable and avoids mixing paradigms.

2. Previously, some functions operated on element counts (nelems), while others expected byte sizes but still used `nelems` as the param name. That inconsistency was easy to miss and could lead to bugs, especially for devs not familiar with the NVSHMEM internals.

To clean this up:
	•	All byte-based APIs now use nbytes or nbytes_per_pe to make the units explicit.
	•	Typed APIs consistently use nelems for element counts.
	•	Docstrings were added or updated to clarify expected units.

Also did some code cleanup — removed unused functions, fixed typos in comments, and did some general housekeeping.

This should make the API more intuitive and reduce friction for developers.

Subject: [PATCH 0135/1424] [SymmMem] Fix flaky wait_until test (#159215)

When playing around with it, I noticed some flakiness in this test across sessions.

After debugging, turns out the heavy sync primitives that I was calling (like `nvshmem_quiet()` or `nvshmem_fence()`) from inside Triton kernels was causing deadlocks. The original test tried to guarantee ordering: `put(data) -> fence/quiet -> put(flag)`. But the GPU thread got stuck in `quiet()` waiting for network confirmation while holding the SM, creating a deadlock.

The fix was realizing `wait_until` already provides all the sync you need. Just do:
- PE A: `nvshmem_wait_until(&ivar, ...)`
- PE B: `nvshmem_put(&ivar_on_PE_A, ...)`

Subject: [PATCH 0136/1424]  [SymmMem] Add Triton 3.4 support to NVSHMEM Triton
 and fix CI tests (make device library discoverable + fix peer calculation
 bug)  (#159701)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR introduces support for Triton 3.4 and resolves several CI and test-related issues.

**Triton 3.4 Compatibility**
- The JIT post-compile hook has been updated from the legacy JITFunction.compiled_hook to the new API path at triton.knobs.runtime.jit_post_compile_hook.
- The internal parameter for kernel semantics in extern function definitions has been updated from _semantic to _builder to align with API changes.

**Fix CI Errors**
- The new logic inspects the RPATH of libtorch_nvshmem.so to find the NVSHMEM device library, preventing CI tests from being skipped.
- Added a decorator to run NVSHMEM tests only on H100s (compatible hardware)

**Peer Rank Calculation Fix**
- The peer calculation in test_nvshmem_triton.py was changed from peer = (world_size - 1) - rank to peer = 1 - rank.
Reasoning: The previous logic was only valid for a 2-rank setup. In the 8-rank CI environment, it incorrectly mapped peers (e.g., rank 0 to 7), breaking tests that assume a 0↔1 communication pattern. This was reproduced and validated on an 8-rank dev setup.

Subject: [PATCH 0137/1424] [SymmMem] Initialize NVSHMEM module only for
 kernels that have nvshmem in their name (#159734)

Previously, a global post-compile hook initialized the NVSHMEM module for all Triton kernels, which was inefficient. This change conditionally initializes  `_nvshmemx_cumodule_init(kernel.module)` only for Triton kernels containing "nvshmem" in their name. Also updated the names for all of our nvshmem kernels to align with this.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/159734
Approved by: https://github.com/ngimel

This change introduces a single, generic Triton‐extern wrapper for NVSHMEM team‐based reductions. We now expose one function, `nvshmem.reduce(team, dest, source, nreduce, operation, dtype_id)`, that covers all supported ops (sum, max, min, prod) and dtypes (int8…int64, uint8…uint64, float16, bfloat16, float32, float64).

It accepts real dtype objects (torch.dtype or tl.dtype) directly in the Triton kernel launch. Internally, we normalize dtype_id (handling tl.dtype, torch.dtype, str, or constexpr) into the canonical NVSHMEM typename and assemble the proper function name, e.g. nvshmem_float_sum_reduce or nvshmem_bfloat16_prod_reduce

+        Broadcast data from a root PE to all other PEs in a team.
+
+        This function implements a collective broadcast operation where the root PE
+        sends its data to all other PEs in the team. All PEs (including the root)
+        receive a copy of the data from the root PE in their destination buffer.
+
+        Args:
+            team (int64): Team handle for the collective operation. Use 0 for NVSHMEM_TEAM_WORLD
+                         (all PEs in the job).
+            dest (int64): Symmetric address of the destination buffer on all PEs.
+                         Must be large enough to hold size_bytes.
+            source (int64): Symmetric address of the source buffer on the root PE.
+                           Only the root PE's source buffer is used.
+            size_bytes (int64): Number of bytes to broadcast. Must be positive.
+            pe_root (int64): PE number of the root PE that provides the source data.
+            _semantic: Optional semantic information for Triton compilation.
+
+        Returns:
+            int32: Status code (0 for success).
+
+        Notes:
+            - This is a collective operation - all PEs in the team must participate.
+            - Must be called from kernels launched with cooperative launch.
+            - Only the root PE's source buffer is read; other PEs' source buffers are ignored.
+            - All PEs (including root) receive the data in their destination buffer.
+            - All PEs must call with the same team, size_bytes, and pe_root values.
+            - The source and destination buffers must not overlap on any PE.
+            - Efficient one-to-many communication pattern.
+
+        Example:
+            ```
+            # PE 0 broadcasts 1024 bytes to all PEs in the team
+            team_world = 0
+            root_pe = 0
+            nvshmem.broadcastmem_block(team_world, dest_ptr, src_ptr, 1024, root_pe)

Subject: [PATCH 0140/1424] [SymmMem] Send tensors with unerased type
 information to NVSHMEM Triton kernels (#159788)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR introduces a small `@triton.jit` wrapper function over our core NVSHMEM extern functions for users to send tensors as inputs to their NVSHMEM Triton kernels (rather than pointers).

The goal is to abstract away tedious details from the developer, like manual byte-size calculations and handling of raw `int64` pointers. This lets developers work directly with typed Triton tensors and element counts, which will also be useful if you want to do for instance some local math on the data.

-----

**TODO:**
This is almost complete. One pending item is tensor-aware implementation of `nvshmem.putmem_signal_block `and `nvshmem.signal_wait_until`

From my investigation, I found the root cause to be that this specific tensor API uses local addresses instead of remote addresses for the peer

```
Pointer-Based Version:

  Rank 0 → Rank 1:
    Local buffer:   0x430300a00  (src)
    Remote buffer:  0x2430300c00 (dst) ← Rank 1's memory
    Remote signal:  0x2430301600 (sig) ← Rank 1's signal

  Rank 1 (waiting):
    Local signal:   0x430301600 (waits here)

Tensor-Based Version:

  Rank 0 → Rank 1:
    Local buffer:   0x430300a00  (src)
    Local buffer:   0x430300c00  (dst) ← this is wrong
    Local signal:   0x430300e00  (sig) ← this is wrong

  Rank 1 (waiting):
    Local signal:   0x430300e00 (waits here)

```

Next Steps: Need mechanism to resolve local tensor → remote PE address, equivalent to handle.buffer_ptrs[peer] lookup.

Subject: [PATCH 0144/1424] [inductor][triton] support profile_scratch launcher
 arg (#159772)

This adds support for Triton after https://github.com/triton-lang/triton/pull/7258 landed. https://github.com/triton-lang/triton/pull/7258 adds a new argument to all the Triton kernels - a profile_scratch argument, similar to global_scratch. This PR updates the static cuda launcher and the AOTI kernel callers to pass in these arguments when calling the Triton kernel.

Tests: https://github.com/pytorch/pytorch/pull/159158. I also verified these test locally with triton 3.2, 3.3, and 3.4.

Fixes:
* static_cuda_launcher (test/repro: `python tools/dynamo/verify_dynamo.py`)
* AOTI calling logic (test/repro: `TORCHINDUCTOR_CPP_WRAPPER=1 python test/inductor/test_torchinductor_opinfo.py -k test_comprehensive_linalg_vander_cuda_float32`)

Subject: [PATCH 0145/1424] Working setup with runnable PyTorch on Codex.
 (#159968)

Sample transcript: https://chatgpt.com/s/cd_68938effc1a88191ae78bc82a8cefe94

This makes use of https://github.com/pytorch/pytorch/pull/159965 to bypass doing an actual build and use nightly.

Things to improve:
- Once USE_NIGHTLY is in main can remove the patching
- We should just keep using the latest nightly, instead of a hard coded one

Subject: [PATCH 0146/1424] Improve pin_memory error message on CPU-only
 systems (#159994)

## Summary
- clarify pin_memory error message when no accelerator backend is available

## Testing
- `python repro_pin_memory.py` (fails: Need to provide pin_memory allocator to use pin memory)
- `lintrunner -a`

Subject: [PATCH 0151/1424] [MPS] Move max_pool2d to Metal for `stride != 1`
 (#157876)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR updates `max_pool2d` to use a Metal kernel instead of the old MPS graph impl. However, when the `stride` argument is 1 in all dimensions, the old implementation gives significantly better performance, so we fall back to it in that case. Below is a performance comparison of `max_pool2d` before and after this PR, obtained from this script: https://github.com/kurtamohler/pytorch-perf-test-scripts/blob/2f02f2bf7ad8e1b80d8eb728612b179d48fe92d7/max_pool_mps/perf.py

Subject: [PATCH 0153/1424] Add DeviceAllocator as the base device allocator
 (#138222)

# Motivation
In line with [RFC] [A device-agnostic Python device memory related API design for stream-based accelerators](https://github.com/pytorch/pytorch/issues/134978), some memory-related APIs are widely used in popular repositories, such as HuggingFace [so many if-else conditional code](https://github.com/search?q=repo%3Ahuggingface%2Faccelerate%20torch.cuda.empty_cache&type=code). We would like to introduce a generic API set under torch.accelerator namespace to generalize these user cases.

# Solution
This design follows a similar pattern to `HostAllocator`. We're introducing a base class `DeviceAllocator`, from which `CUDAAllocator` and `XPUAllocator` will inherit. This allows us to provide a unified call path like: `torch.accelerator.empty_cache()` -> `GetDeviceAllocator(allocator)->empty_cache()`.

Subject: [PATCH 0156/1424] [ROCm] Ck backend UX refactor (#152951)

Refactors how the enablement/disablement of CK Gemms and SDPA works.

- Adds USE_ROCM_CK_GEMM compile flag for enabling CK gemms.
- USE_ROCM_CK_GEMM is set to True by default on Linux
- Updates USE_CK_FLASH_ATTENTION to USE_ROCM_CK_SDPA.
- USE_ROCM_CK_SDPA is set to False by default
- (USE_CK_FLASH_ATTENTION still works for now, but will be deprecated in a future release)
- Prevents these CK libraries from being used unless pytorch has been built specifically with the functionality AND is running on a system architecture that supports it.
- the getters for these library backends will also do some validity checking in case the user used an environment variable to change the backend. If invalid, (i.e. one of the cases mentioned above is false) the backend will be set as the current non-CK default

+Enabling/Disabling ROCm Composable Kernel
+-----------------------------------------
+
+Enabling composable_kernel (CK) for both SDPA and GEMMs is a two-part process. First the user must have built
+pytorch while setting the corresponding environment variable to '1'
+
+SDPA:
+``USE_ROCM_CK_SDPA=1``
+
+GEMMs:
+``USE_ROCM_CK_GEMM=1``
+
+Second, the user must explicitly request that CK be used as the backend library via the corresponding python
+call
+
+SDPA:
+``setROCmFAPreferredBackend('<choice>')``
+
+GEMMs:
+``setBlasPreferredBackend('<choice>')``
+
+To enable CK in either scenario, simply pass 'ck' to those functions.
+
+In order to set the backend to CK, the user MUST have built with the correct environment variable. If not,
+PyTorch will print a warning and use the "default" backend. For GEMMs, this will route to hipblas and
+for SDPA it routes to aotriton.

Subject: [PATCH 0157/1424] [replicate][be] improved readability and cleaned up
 remaining DDP code (#160133)

**Summary**
As much of ReplicateState functionality is copied from FSDPState, I fixed any remaining comments that incorrectly used FSDP instead of Replicate. In addition, instead of labeling modules FSDPModule or FSDPLinear, I have changed it so that is now uses Replicate____. Finally, I have removed some leftover code from the DDP implementation. I have included test cases to verify correctness.

**Test Case**
1. pytest test/distributed/_composable/test_replicate_with_fsdp.py

Pull Request resolved: https://github.com/pytorch/pytorch/pull/160133

Subject: [PATCH 0160/1424] Do not treat ReinterpretView as a realized node
 (#159920)

Summary:
Do not treat ReinterpretView as a realized node

Function [gather_origins](https://github.com/pytorch/pytorch/blob/main/torch/_inductor/utils.py#L888](https://l.facebook.com/l.php?u=https%3A%2F%2Fgithub.com%2Fpytorch%2Fpytorch%2Fblob%2Fmain%2Ftorch%2F_inductor%2Futils.py%23L888&h=AT2PYr83thTo6VUjPs26Y8QAN6Sid16rvDMHtxO-Bp9FDwHr4J5PObtH3IhNTL-LPSRVC9WVJAcmwUToVWJIrDWb84i0j61QE55ySYAkGbuigqcNc7xczlirHhbiC9vMqiz91VwWdl4Pe2yKN7VIjjCiFUqw) calls is_realized_node to decide if a FX node should be included in the origins of a IR node. ReinterpretView is considered a realized node, so it is not included in the origins. It leads to an incomplete graph. For example:

```
@torchdynamo.optimize("inductor")
def fn(input_data, weight):
    normalized_input = input_data * weight.unsqueeze(0)
    return normalized_input
input_data = torch.randn(4272, 192, requires_grad=True).to(device)
weight = torch.randn(192, requires_grad=True).to(device)
fn(input_data, weight)
```

The original FX graph returned in [get_kernel_metadata](https://github.com/pytorch/pytorch/blob/main/torch/_inductor/utils.py#L723](https://l.facebook.com/l.php?u=https%3A%2F%2Fgithub.com%2Fpytorch%2Fpytorch%2Fblob%2Fmain%2Ftorch%2F_inductor%2Futils.py%23L723&h=AT2PYr83thTo6VUjPs26Y8QAN6Sid16rvDMHtxO-Bp9FDwHr4J5PObtH3IhNTL-LPSRVC9WVJAcmwUToVWJIrDWb84i0j61QE55ySYAkGbuigqcNc7xczlirHhbiC9vMqiz91VwWdl4Pe2yKN7VIjjCiFUqw) is the following:
%primals_2 : Tensor "f32[4272, 192][192, 1]cuda:0" = PlaceHolder[target=primals_2]
%primals_1 : Tensor "f32[192][1]cuda:0" = PlaceHolder[target=primals_1]
%mul : Tensor "f32[4272, 192][192, 1]cuda:0"[num_users=1] = call_function[target=torch.ops.aten.mul.Tensor](args = (%primals_2, %unsqueeze), kwargs = {})
return %mul
The unsqueeze op is missing.

With this DIFF, the new FX graph is the following:
%primals_2 : Tensor "f32[4272, 192][192, 1]cuda:0" = PlaceHolder[target=primals_2]
%primals_1 : Tensor "f32[192][1]cuda:0" = PlaceHolder[target=primals_1]
%unsqueeze : Tensor "f32[1, 192][192, 1]cuda:0"[num_users=1] = call_function[target=torch.ops.aten.unsqueeze.default](args = (%primals_1, 0), kwargs = {})
%mul : Tensor "f32[4272, 192][192, 1]cuda:0"[num_users=1] = call_function[target=torch.ops.aten.mul.Tensor](args = (%primals_2, %unsqueeze), kwargs = {})
return %mul

+Tuning NVLink Performance with Custom Memory Allocator on H100/H200 GPUs
+------------------------------------------------------------------------
+In rare cases, performance of NVLink on H100/H200 GPUs can be influenced by the physical memory
+layout of data, creating an opportunity for developers to tune their applications for optimal
+throughput.
+
+An example of how physical memory layout of data affects performance is when communication
+kernels issue unbalanced NVLink read/write operations. In the following figure, we can see
+that each warp accesses memory addresses with a consistent strided pattern in each single wave.
+We can have a more balanced load by tuning the stride size in the workload or we can implement
+a custom CUDA allocator.
+
+.. code::
+
+  _______________________________  _______________________________      _______________________________
+  | Warp 0 Reading | No-reading |  | Warp 1 Reading | No-reading |  ...  Warp N Reading | No-reading |
+  _______________________________  _______________________________      _______________________________
+  <----------------------------->
+          Stride size
+
+Such an allocator can maintain contiguous virtual memory addresses for the kernel while strategically
+arranging the mapping to physical memory addresses (e.g., through shuffling). This technique allows
+developers to explore different physical access patterns to find the most efficient one, unlocking
+higher performance without modifying the kernel's logic. A practical implementation of such an allocator
+can be achieved using PyTorch’s custom allocator support as mentioned before, where the malloc and free
+functions are:
+
+.. code:: C++
+
+  // assuming a system with 8 GPUs
+  struct CustomAllocInfo {
+    void** devPtr;  // This will be the usable virtual memory address
+    CUdeviceptr dptr;
+    size_t totalSize;  // Total size of the allocated memory
+    size_t padded_size;
+    int device_id;

Subject: [PATCH 0162/1424] [MPS] Extend `index_put` to complex types (#160159)

And delete confusing supported types check.
Move all pseudo atomic (but eventually consistent) ops to `c10/metal/atomic.h` header

Fixes https://github.com/pytorch/pytorch/issues/160034

Subject: [PATCH 0163/1424] Revert "[pytorch][dynamo_compile] Log stack_trace
 to dynamo_compile (#159655)"

This reverts commit 2ee22e435131369a7e4f8cc4732579acc29a941b.

Reverted https://github.com/pytorch/pytorch/pull/159655 on behalf of https://github.com/clee2000 due to broke dynamo/test_utils.py::TestDynamoTimed::test_dynamo_timed [GH job link](https://github.com/pytorch/pytorch/actions/runs/16839294394/job/47711078667) [HUD commit link](https://hud.pytorch.org/pytorch/pytorch/commit/2ee22e435131369a7e4f8cc4732579acc29a941b).  Probably a landrace since it did run on the PR ([comment](https://github.com/pytorch/pytorch/pull/159655#issuecomment-3169400889))

Subject: [PATCH 0166/1424] Fix test_fsdp_ep.py due to _MeshEnv API change
 (#158695)

#132339 changed parent/child mesh related APIs from _MeshEnv. UT TestFSDPWithEP.test_e2e still uses old APIs and will fail:
```
File "/home/kanya/pytorch/test/distributed/checkpoint/e2e/test_fsdp_ep.py", line 77, in test_e2e
    mesh_fsdp_ep = _mesh_resources.create_child_mesh(mesh_fsdp_tp, ("dp",))
AttributeError: '_MeshEnv' object has no attribute 'create_child_mesh'

To execute this test, run the following from the base repo dir:
    python test/distributed/checkpoint/e2e/test_fsdp_ep.py TestFSDPWithEP.test_e2e

This message can be suppressed by setting PYTORCH_PRINT_REPRO_ON_FAILURE=0. Did you mean: 'create_sub_mesh'?
```

Pip wheels of PyTorch nightly and 2.8 release candidates do not contain `cutlass_mock_imports`.

This is the path to the source code:

Subject: [PATCH 0170/1424] [MPS][BE] Combine all pre-MacOS14 xfail lists
 (#160228)

It does not matter whether it started to fail after 13.1 or 13.3, fact
that it still fails on latest MacOS

Subject: [PATCH 0171/1424] [BE] Remove more optim entries from docs coverage
 ignore list (#160194)

This PR does privatize ReduceLRSchedulerOnPlateau.is_better -> ReduceLRSchedulerOnPlateau._is_better because that API was never meant to be public. A GitHub search for it also reveals that the API is not commonly used much. https://github.com/search?q=.is_better%28&type=code&p=2

If you do use this API and you rely on it for some reason, please file an issue. In the meantime, you can access it through `_is_better(...)`.

Subject: [PATCH 0172/1424] [dcp][hf] Improve HF consolidation algorithm
 (#158648)

Before we had a bunch of if-else cases based on sharding strategy to decide how to save the tensor with different logic for different strategies. This can be consolidated into one function that uses an algorithm to handle all cases by finding the max possible contiguous bytes that can be written

Subject: [PATCH 0173/1424] [Torch Native] Add test for packaging weight 
 (#158750)

Add test that require weights to be packaged for torch native

For now, we need `package_weights_in_so=True` for compile standalone. The constants are in a `.o` file and will be added as a source to the CMakeLists.txt of the model.

After we added weight deduping, we should be able to let this config be False.

```
python test/inductor/test_aot_inductor_package.py  -k test_compile_with_exporter_weights
```

-# TensorExpr C++ Tests
-
-## How to add a new test
-First, create a new test file. Test files should have be placed in this
-directory, with a name that starts with `test_`, like `test_foo.cpp`.
-
-Here is an example test file you can copy-paste.
-```cpp
-#include <test/cpp/tensorexpr/test_base.h>
-
-// Tests go in torch::jit
-namespace torch {
-namespace jit {
-
-// 1. Test cases are void() functions.
-// 2. They start with the prefix `test`
-void testCaseOne() {
-    // ...
-}
-
-void testCaseTwo() {
-    // ...
-}
-}
-}
-```
-
-Then, register your test in `tests.h`:
-```cpp

-order to get the build to pick up your new test file, you need to re-run
-cmake:
-```bash
-CMAKE_FRESH=1 python setup.py build
-```
-
-## How do I run the tests?
-The following commands assume you are in PyTorch root.
-
- ```bash
- # (re)build the test binary
- ninja build/bin/test_tensorexpr
- # run
- build/bin/test_tensorexpr --gtest_filter='glob_style_filter*'

-// *** Tensor Expressions ***
-//
-// This tutorial covers basics of NNC's tensor expressions, shows basic APIs to
-// work with them, and outlines how they are used in the overall TorchScript
-// compilation pipeline. This doc is permanently a "work in progress" since NNC
-// is under active development and things change fast.
-//
-// This Tutorial's code is compiled in the standard pytorch build, and the
-// executable can be found in `build/bin/tutorial_tensorexpr`.
-//
-// *** What is NNC ***
-//
-// NNC stands for Neural Net Compiler. It is a component of TorchScript JIT
-// and it performs on-the-fly code generation for kernels, which are often a
-// combination of multiple aten (torch) operators.
-//
-// When the JIT interpreter executes a torchscript model, it automatically
-// extracts subgraphs from the torchscript IR graph for which specialized code
-// can be JIT generated. This usually improves performance as the 'combined'
-// kernel created from the subgraph could avoid unnecessary memory traffic that
-// is unavoidable when the subgraph is interpreted as-is, operator by operator.
-// This optimization is often referred to as 'fusion'. Relatedly, the process of
-// finding and extracting subgraphs suitable for NNC code generation is done by
-// a JIT pass called 'fuser'.
-//
-// *** What is TE ***
-//
-// TE stands for Tensor Expressions. TE is a commonly used approach for
-// compiling kernels performing tensor (~matrix) computation. The idea behind it
-// is that operators are represented as a mathematical formula describing what
-// computation they do (as TEs) and then the TE engine can perform mathematical
-// simplification and other optimizations using those formulas and eventually
-// generate executable code that would produce the same results as the original
-// sequence of operators, but more efficiently.
-//
-// NNC's design and implementation of TE was heavily inspired by Halide and TVM
-// projects.

-    // A tensor expression is a tree of expressions. Each expression has a type,
-    // and that type defines what sub-expressions the current expression has.
-    // For instance, an expression of type 'Mul' would have a type 'kMul' and
-    // two subexpressions: LHS and RHS. Each of these two sub-expressions could
-    // also be a 'Mul' or some other expression.
-    //
-    // Let's construct a simple TE:
-    ExprPtr lhs = alloc<IntImm>(5);
-    ExprPtr rhs = alloc<Var>("x", kInt);
-    ExprPtr mul = alloc<Mul>(lhs, rhs);
-    std::cout << "Tensor expression: " << *mul << std::endl;
-    // Prints: Tensor expression: 5 * x
-
-    // Here we created an expression representing a 5*x computation, where x is
-    // an int variable.
-
-    // Another, probably a more convenient, way to construct tensor expressions
-    // is to use so called expression handles (as opposed to raw expressions
-    // like we did in the previous example). Expression handles overload common
-    // operations and allow us to express the same semantics in a more natural
-    // way:
-    ExprHandle l = 5;
-    ExprHandle r = Var::make("x", kInt);
-    ExprHandle m = l * r;
-    std::cout << "Tensor expression: " << *m.node() << std::endl;
-    // Prints: Tensor expression: 5 * x
-
-    // Converting from handles to raw expressions and back is easy:
-    ExprHandle handle = Var::make("x", kInt);
-    ExprPtr raw_expr_from_handle = handle.node();
-    ExprPtr raw_expr = alloc<Var>("x", kInt);
-    ExprHandle handle_from_raw_expr = ExprHandle(raw_expr);
-
-    // We could construct arbitrarily complex expressions using mathematical
-    // and logical operations, casts between various data types, and a bunch of
-    // intrinsics.
-    ExprHandle a = Var::make("a", kInt);
-    ExprHandle b = Var::make("b", kFloat);
-    ExprHandle c = Var::make("c", kFloat);
-    ExprHandle x = ExprHandle(5) * a + b / (sigmoid(c) - 3.0f);
-    std::cout << "Tensor expression: " << *x.node() << std::endl;
-    // Prints: Tensor expression: float(5 * a) + b / ((sigmoid(c)) - 3.f)
-
-    // An ultimate purpose of tensor expressions is to optimize tensor
-    // computations, and in order to represent accesses to tensors data, there
-    // is a special kind of expression - a load.
-    // To construct a load we need two pieces: the base and the indices. The
-    // base of a load is a Buf expression, which could be thought of as a
-    // placeholder similar to Var, but with dimensions info.
-    //
-    // Let's construct a simple load:
-    BufHandle A("A", {64, 32}, kInt);
-    VarPtr i_var = alloc<Var>("i", kInt), j_var = alloc<Var>("j", kInt);
-    ExprHandle i(i_var), j(j_var);
-    ExprHandle load = Load::make(A.dtype(), A, {i, j});
-    std::cout << "Tensor expression: " << *load.node() << std::endl;
-    // Prints: Tensor expression: A[i, j]
-
-    // Tensor Expressions constitute Tensor Statements, which are used to
-    // represent computation of a given operator or a group of operators from a
-    // fusion group.
-    //
-    // There are three main kinds of tensor statements:
-    //  - block
-    //  - store
-    //  - loop
-    //
-    // A Store represents a store to a single element of a tensor (or to a
-    // group of elements if it's a vectorized store). Store statements,
-    // similarly to Load expressions, have a base and indices, but on top of
-    // that they also include a value - an expression representing what needs
-    // to be stored at the given memory location. Let's create a Store stmt:
-    StmtPtr store_a = Store::make(A, {i, j}, i + j);
-    std::cout << "Store statement: " << *store_a << std::endl;
-    // Prints: Store statement: A[i, j] = i + j;
-
-    // An operator fills the entire tensor, not just a single element, and to
-    // represent this we need to use For stmt: let's wrap our store stmt with
-    // two nested loops to represent that variables i and j need to iterate
-    // over some ranges.
-    ForPtr loop_j_a = For::make(VarHandle(j_var), 0, 32, store_a);
-    ForPtr loop_i_a = For::make(VarHandle(i_var), 0, 64, loop_j_a);
-

-
-    // A Block statement is used when we need a sequence of other statements.

-    // separate loopnest for each of them and put them all into a common block:
-    BufHandle B("B", {64, 32}, kInt);
-    StmtPtr store_b = Store::make(B, {i, j}, A.load(i, j));
-    ForPtr loop_j_b = For::make(VarHandle(j_var), 0, 32, store_b);
-    ForPtr loop_i_b = For::make(VarHandle(i_var), 0, 64, loop_j_b);

-    //     }
-    //   }
-    // }
-
-    // Manually constructing nested loops and blocks to represent a computation
-    // might be laborious, and instead we can use a 'Compute' API. This API
-    // requires us to specify dimensions and a lambda to compute a single
-    // element of the resulting tensor and returns a `Tensor` structure. This
-    // structure is simply a pair of a buffer that was created to represent the
-    // result of the computation (BufPtr) and a statement representing the
-    // computation itself (StmtPtr).
-    Tensor C =
-        Compute("C", {64, 32}, [&](const VarHandle& i, const VarHandle& j) {

-
-    // To construct statements to represent computations with reductions, we

-    // An ultimate goal of tensor expressions is to be provide a mechanism to
-    // execute a given computation in the fastest possible way. So far we've
-    // looked at how we could describe what computation we're interested in, but
-    // we haven't looked at how to actually execute it.
-    //
-    // All we've been dealing with was just symbols with no actual data
-    // associated, in this section we would look at how we can bridge that gap.
-
-    // Let's start by constructing a simple computation for us to work with:
-    BufHandle A("A", {64, 32}, kInt);
-    BufHandle B("B", {64, 32}, kInt);
-    Tensor X =
-        Compute("X", {64, 32}, [&](const VarHandle& i, const VarHandle& j) {
-          return A.load(i, j) + B.load(i, j);
-        });
-
-    // And let's lower it to a loop nest, as we did in the previous section. We
-    // can pass Tensor object directly:
-    LoopNest loopnest({X});
-    std::cout << *loopnest.root_stmt() << std::endl;
-    // Prints:
-    // {
-    //   for (const auto i : c10::irange(64)) {
-    //     for (const auto j : c10::irange(32)) {
-    //       X[i, j] = (A[i, j]) + (B[i, j]);
-    //     }
-    //   }
-
-    // Now imagine that we have two actual tensors 64x32 that we want sum
-    // together, how do we pass those tensors to the computation and how do we
-    // carry it out?
-    //
-    // Codegen object is aimed at providing exactly that functionality. Codegen
-    // is an abstract class and concrete codegens are derived from it.
-    // Currently, we have three codegens:
-    //  1) Simple Evaluator,
-    //  2) LLVM Codegen for CPU,
-    //  3) CUDA Codegen.
-    // In this example we will be using Simple Evaluator, since it's available
-    // everywhere.
-
-    // To create a codegen, we need to provide the statement - it specifies the
-    // computation we want to perform - and a list of placeholders and tensors
-    // used in the computation. The latter part is crucial since that's the only
-    // way the codegen could use to correlate symbols in the statement to actual
-    // data arrays that we will be passing when we will actually be performing
-    // the computation.
-    //
-    // Let's create a Simple IR Evaluator codegen for our computation:
-    SimpleIREvaluator ir_eval(loopnest.root_stmt(), {A, B, X});
-
-    // We are using the simplest codegen and in it almost no work is done at the
-    // construction step. Real codegens such as CUDA and LLVM perform
-    // compilation during that stage so that when we're about to run the
-    // computation everything is ready.
-
-    // Let's now create some inputs and run our computation with them:
-    std::vector<int> data_A(64 * 32, 3); // This will be the input A
-    std::vector<int> data_B(64 * 32, 5); // This will be the input B
-    std::vector<int> data_X(64 * 32, 0); // This will be used for the result
-
-    // Now let's invoke our codegen to perform the computation on our data. We
-    // need to provide as many arguments as how many placeholders and tensors we
-    // passed at the codegen construction time. A position in these lists would
-    // define how real data arrays from the latter call (these arguments are
-    // referred to as 'CallArg's in our codebase) correspond to symbols
-    // (placeholders and tensors) used in the tensor expressions we constructed
-    // (these are referred to as 'BufferArg').
-    // Thus, we will provide three arguments: data_A, data_B, and data_X. data_A
-    // contains data for the placeholder A, data_B - for the placeholder B, and
-    // data_X would be used for contents of tensor X.
-    ir_eval(data_A, data_B, data_X);
-
-    // Let's print one of the elements from each array to verify that the
-    // computation did happen:
-    std::cout << "A[10] = " << data_A[10] << std::endl
-              << "B[10] = " << data_B[10] << std::endl
-              << "X[10] = A[10] + B[10] = " << data_X[10] << std::endl;
-    // Prints:
-    // A[10] = 3
-    // B[10] = 5
-    // X[10] = A[10] + B[10] = 8

-    parseIR(graph_string, &*graph);
-
-    // This graph defines a simple computation of A*A*B + B where A and B are
-    // input 5x3 tensors.
-
-    // To lower this TorchScript graph to TE, we just need to create a
-    // TensorExprKernel object. In its constructor it constructs the
-    // corresponding TE IR and compiles it for the given backend (in this
-    // example for CPU using LLVM compiler).
-    TensorExprKernel kernel(graph);
-
-    // We can retrieve the generated TE stmt from the kernel object:
-    StmtPtr kernel_stmt = kernel.getCodeGenStmt();
-    std::cout << "TE Stmt constructed from TorchScript: " << std::endl
-              << *kernel_stmt << std::endl;

Subject: [PATCH 0182/1424] [Linter] Expanding the scope of detecting
 device-bias code. (#159949)

Currently, the device-bias linter only targets functions decorated with @requires_gpu. This PR adds support for two new detection scenarios:
1. Detect device-bias code in functions decorated with @requires_triton.
2. Detect device-bias code for entire test suites that are defined as shared across GPUs. For example:
```
if __name__ == "__main__":
    if HAS_GPU:
        run_tests()

```

Subject: [PATCH 0186/1424] Fix get_free_symbol_uses for several nodes.
 (#160134)

get_free_symbol_uses is used to know what unbacked symbols are used by a given node.
not having correct get_free_symbol_uses defined properly leads to :
1. eliminating of some nodes due to not detection of any users. (See the added unit test)
2. Incorrect topological sort.

Fix get_free_symbol_uses , NopKernel , ConcarKernel, InputsKerenl, external kernel.
for ComputedBuffer with NonOwningLayout its interesting case.
when layout is NonOwningLayout we need to access the actual view op base layout and use
detect symbols in it. Because when we codegen the ComputedBuffer we uses those symbols.

Subject: [PATCH 0187/1424] [inductor] turn on windows inductor UTs (#160161)

With this PR, we can turn on the inductor UTs on Windows CPU.

changes:
1. Turn on inductor UTs on Windows CPU.
2. Add a shard to balance added UTs, otherwise it should run timeout.
3. Fixed `test_invalid_artifact_flag_error_msg`.
4. Skiped `test_distributed_rank_logging` and `test_disable_recursive_false`.
5. Skiped whole UT `test_cpu_select_algorithm.py`.

Subject: [PATCH 0190/1424] Correctly copy self.module_stack in
 ModuleStackTracer (#159956)

There is a bigger cluster of issues which this does not completely fix, but I think this is a matter of good hygiene, especially because we immediately mutate the dict after assigning it.

Subject: [PATCH 0199/1424] [inductor] turn on windows inductor UTs (#160161)

With this PR, we can turn on the inductor UTs on Windows CPU.

changes:
1. Turn on inductor UTs on Windows CPU.
2. Add a shard to balance added UTs, otherwise it should run timeout.
3. Fixed `test_invalid_artifact_flag_error_msg`.
4. Skiped `test_distributed_rank_logging` and `test_disable_recursive_false`.
5. Skiped whole UT `test_cpu_select_algorithm.py`.

Subject: [PATCH 0201/1424] [MPS] Extend addmm to integral types (#160270)

By adding `addmm` kernel, which is a logical continuation  of `mm` one. The only tricking part are how alpha and beta constants are handled, which are passed as `optmath_t`, i.e. that it could be, int64, int32 or float

Unified all MM flavors instantiations thru `INSTANTIATE_MM_OPS` and tested that `addmm` metal kernel works as expected for floating types as well by testing it via
```
 PYTORCH_MPS_PREFER_METAL=1 python test/test_mps.py -v -k test_output_match_addmm_mps_
```

```

Based on my reading about B200 power usage, I believe this is due to the new for power aware benchmarking as a kernel may perform better in short bursts. This adds environment variables to expand autotuning iterations so we can get more consistent results between the estimation and the actual runtime. I did not update the default yet, even for B200 because I'm not sure how this is used in practice.

This is the new output:

```

Subject: [PATCH 0210/1424] Fix clang builds by adding headers (#160252)

Clang compiler from llvm-14 fails to build full torch from source with the message
```
no template named 'unordered_map' in namespace 'std'
  std::unordered_map<std::string, HandlerFunc> handlers_{};
 ~~~~~^
```
A similar issue here https://github.com/intel/llvm/issues/5264
Fix is to add the correct headers.

Subject: [PATCH 0214/1424] [submodule] Bump fbgemm to latest (#158210)

Merge the recent commits of FBGEMM and remove unnecessary CMake code.
Specifically, we
1. enable `fbgemm_autovec` since the target is now correctly handled.
2. remove option `USE_FAKELOWP` which is not used.
3. remove `CAFFE2_COMPILER_SUPPORTS_AVX512_EXTENSIONS` check.

Subject: [PATCH 0217/1424] [codemod] Fix unreachable-break issue in
 caffe2/c10/cuda/CUDAFunctions.cpp +2 (#160257)

Summary:
LLVM has a warning `-Wunreachable-code-break` which identifies `break` statements that cannot be reached. These compromise readability, are misleading, and may identify bugs. This diff removes such statements.

Subject: [PATCH 0218/1424] [Graph Partition] Pass all OSS unit tests (#154667)

Graph partition leads to 6.2% speedup on vision_maskrcnn, 5.8% speedup on yolov3. [P1819700563](https://www.internalfb.com/phabricator/paste/view/P1819700563), 39.5% speedup on speech_transformer inference [P1830602200](https://www.internalfb.com/phabricator/paste/view/P1830602200), 85% speedup on speech_transformer training [P1831115315](https://www.internalfb.com/phabricator/paste/view/P1831115315).

Run the same diff on two days and both show speedup on average.

Subject: [PATCH 0219/1424] Fix unbacked symint and memory leak in inductor
 memory planning (#159839)

Summary:

In memory planning, some allocation sizes involve unbacked symints. These unbacked symints are not known before they are computed in run time, so **allocation pools that involve unbacked symints cannot be allocated until we have the values of the unbacked symints** .

So we add a notion of `earliest_available` to Allocation nodes. If an allocation node has unbacked symint, it is available at only when its live range begin.

Then in AllocationPool, if a pool involves an Allocation node that has an earliest available time, we restrict its life range.

If a block's earliest available time is later than a pool's life range's start time, we cannot allocate it from the pool.

We also fix a memory leak that's caused by allocating tensor without wrapping it with RAIIAtenTensor.

In python wrapper for JIT inductor, `codegen_alloc_from_pool` doesn't actually write the alloc lines to wrapper, it just returns the string to alloc. However, in cpp_wrapper, `codegen_alloc_from_pool`  actually write to the wrapper. Specifically, it writes the following and returns string `RAIIAtenTensorHandle`.

```
AtenTensorHandle handle_name;
AOTI_TORCH_ERROR_CODE_CHECK(aoti_torch__alloc_from_pool(....);
```

This is bug prune. **If you write aoti_torch__alloc_from_pool lines, you must write the RAIIAtenTensorHandle as well**, otherwise you get memory leaks.

We remove the alloc_from_pool call from codegen_create, because this doesn't work for AOTI. In python wrapper, we can generate the same alloc_from_pool variable name for the same block, but cpp_wrapper will generate a different variable name for each call to alloc_from_pool.

Test Plan:
```
 python test/inductor/test_memory_planning.py
```

Rollback Plan:

Subject: [PATCH 0220/1424] [triton_heuristics] Optimize the triton launcher in
 pt2 (#160000)

Summary:

(Original author: Xu Zhao. Commandeered by David to land this since it is relatively urgent)

We observed ~10us PT2-Triton launch overhead regression after pin update.

Before Triton pin-update:
 {F1980557238}

After Triton pin-update:
 {F1980557240}

The root cause is because https://github.com/pytorch/pytorch/pull/145051 adds `_get_args_with_constexprs` to the cubin launcher caller function, which is on the critical path.

The motivation for `_get_args_with_constexprs` was that between triton 3.2 and triton 3.3, the convention for calling Triton kernels (at the level that non-static-cuda-launcher inductor integrates) changed. Previously, the callable did not take constexpr arguments as parameters; after 3.3, it does. With pointwise/reduction kernels, we don't know the constexpr values until after autotuning occurs; so `_get_args_with_constexprs` would inject constexprs into the arguments list before calling the Triton kernel. The fix (in this PR) is to instead inject the constexpr args into the launcher string - this avoids the cost of sorting/reordering arguments which previously occurred upon execution of each kernel.

Note that the static_cuda_launcher.py does not require constants to be passed to the cubin launcher (https://github.com/pytorch/pytorch/blob/e96c7c4bb0f6aeae2ab3b6f040f7d67edbec199a/torch/_inductor/runtime/static_cuda_launcher.py#L220), there is no need to pass in constexprs to the generated launcher code.

The new launcher code needs to work on three cases:
- StaticallyLaunchedCudaKernel
- triton.compile.CompiledKernel
- AOTInductor

Subject: [PATCH 0223/1424] port distributed pipeline test files for Intel GPU
 (#159033)

In this PR we will port all distributed pipeline test files.
We could enable Intel GPU with following methods and try the best to keep the original code styles:

1. instantiate_device_type_tests()
2. use "torch.accelerator.current_accelerator()" to determine the accelerator backend
3. use "requires_accelerator_dist_backend()" to replace requires_nccl()
4. use "get_default_backend_for_device()" to get backend
5. enabled XPU for some test path
6. add TEST_MULTIACCELERATOR in common_utils for all backend.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/159033
Approved by: https://github.com/guangyey, https://github.com/d4l3k

Subject: [PATCH 0225/1424] [PGO] no counterfactual suggestions for dynamic
 allowlist  (#160231)

Being more conservative with whitelist suggestions as we roll out suggestions; now we only suggest sources that were dynamic in previous runs.

Subject: [PATCH 0232/1424] [hop][exc] make UncapturedHigherOrderOpError print
 user code and avoid re-raise (#159296)

After the change, the error stacktrace is attached with user code stack and  is suppressed into 1 (without the scrolling up mssage). For example:
```python
    class Test(torch.nn.Module):
        def forward(self, c, x):
            def cond_fn(c, x):
                return c > 0 and x.size(0) < 20

            def body_fn(c, x):
                return c - 1, x.sin()

            return torch._higher_order_ops.while_loop(cond_fn, body_fn, (c, x))
```

Now gives the following error message:
```python

torch._dynamo.exc.UncapturedHigherOrderOpError: while_loop doesn't work unless it is captured completely with torch.compile. Got Data-dependent branching
  Explanation: Detected data-dependent branching (e.g. `if my_tensor.sum() > 0:`). Dynamo does not support tracing dynamic control flow.
  Hint: This graph break is fundamental - it is unlikely that Dynamo will ever be able to trace through your code. Consider finding a workaround.
  Hint: Use `torch.cond` to express dynamic control flow.

  Developer debug context: attempted to jump with TensorVariable()

 For more details about this graph break, please visit: https://pytorch-labs.github.io/compile-graph-break-site/gb/gb0170.html

Set TORCHDYNAMO_VERBOSE=1 for the internal stack trace (please do this especially if you're reporting a bug to PyTorch). For even more developer context, set TORCH_LOGS="+dynamo"

To execute this test, run the following from the base repo dir:
    python test/inductor/test_control_flow.py WhileLoopTests.test_while_loop_size_mismatch_tensor_expansion_device_cpu_dynamic_False

This message can be suppressed by setting PYTORCH_PRINT_REPRO_ON_FAILURE=0

Subject: [PATCH 0233/1424] Update export/schema.py (#160220)

Summary:
Model could have multiple ExportedPrograms
- for different methods. They can have different weights.
- for different delegates. They can also have different weights.

For this reason, we make weight per ExportedProgram.

Also, we cleanup Model, and Program. IIUC, Model and Program are not used anywhere, so it's ok to make BC breaking change.

Test Plan:
CI

Rollback Plan:

Differential Revision: D79917395

Subject: [PATCH 0235/1424] [PP] Initialize P2P communicators on first step
 (#160210)

Was hitting hangs in multi-node settings and initializing the NCCL communicators needed for batch p2p ops ahead of time fixes this.

This change adds extra communication since it communicates a dummy tensor to next and previous stage ranks. However, this is only paid on the first step so it is negligible.

Subject: [PATCH 0236/1424] [ROCm][Windows] Fix LoadHIP handling of environment
 variable paths on Windows. (#159080)

See https://cmake.org/cmake/help/latest/command/file.html#path-conversion. Paths stored in environment variables may use `/` or `\` (e.g. on Windows), while cmake-style paths always use `/`.

This fixes configure errors like:
```
CMake Error at D:/b/pytorch_main/build/CMakeFiles/CMakeScratch/TryCompile-srhq07/CMakeLists.txt:2 (set):
  Syntax error in cmake code at

    D:/b/pytorch_main/build/CMakeFiles/CMakeScratch/TryCompile-srhq07/CMakeLists.txt:2

  when parsing string

    D:\projects\TheRock\external-builds\pytorch\.venv\Lib\site-packages\_rocm_sdk_devel/cmake/;D:/b/pytorch_main/cmake/Modules

  Invalid character escape '\p'.

CMake Error at D:/projects/TheRock/external-builds/pytorch/.venv/Lib/site-packages/cmake/data/share/cmake-3.31/Modules/Internal/CheckSourceCompiles.cmake:108 (try_compile):
  Failed to configure test project build system.
```

(note the mixed usage of `\` and `/` in that string)

This is not really a problem. Sometimes we cannot find a cutlass config due to shape, e.g. when k is odd.

Subject: [PATCH 0242/1424] [BE] Isolate pre-push hook dependencies in
 dedicated virtual environment (#160048)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This adds two changes:
- Isolates pre-push hook dependencies into an isolated venv, no longer affect your system environment
- Lets you manually run the pre-push lintrunner (including with lintrunner -a) by invoking `python scripts/lintrunner.py [-a]` (it's ugly, but better than nothing...for now)

This is a follow up to:
- https://github.com/pytorch/pytorch/pull/158389

## Problem
The current pre-push hook setup installs lintrunner and related dependencies globally, which makes developers nervous about system pollution and can cause version conflicts with existing installations.

Also, if the pre-push lintrunner found errors, you had to hope your normal lintrunner could fix them (which wasn't always the case, e.g. if those errors only manifested in certain python versions)

##  Key Changes:
  - Isolated Environment: Creates .git/hooks/linter/.venv/ with Python 3.9 (the python used in CI) and an isolated lintrunner installation
  - User-Friendly CLI: New python scripts/lintrunner.py wrapper allows developers to run lintrunner (including -a auto-fix) from any environment
  - Simplified Architecture: Eliminates pre-commit dependency entirely - uses direct git hooks

  File Changes:
  - scripts/setup_hooks.py: Rewritten to create isolated uv-managed virtual environment
  - scripts/lintrunner.py: New wrapper script with shared hash management logic
  - scripts/run_lintrunner.py: Removed (functionality merged into lintrunner.py)
  - .pre-commit-config.yaml: Removed (no longer needed)

##  Usage:
```
  # Setup (run once)
  python scripts/setup_hooks.py

  # Manual linting (works from any environment)
  python scripts/lintrunner.py        # Check mode
  python scripts/lintrunner.py -a     # Auto-fix mode

  # Git hooks work automatically
  git push  # Runs lintrunner in isolated environment

  # Need to skip the pre-push hook?
  git push --no-verify
```

##  Benefits:
  - ✅ Zero global dependency installation
  - ✅ Per-repository isolation prevents version conflicts
  - ✅ Full lintrunner functionality is now accessible

##  Implementation Notes:
  - Virtual env is kept in a dedicated dir in .git, to keep per-repo mechanics
  - lintrunner.py does not need to be invoked from a specific venv.  It'll invoke the right venv itself.

A minor bug: It tends to garble the lintrunner output a bit, like the screenshot below shows, but I haven't found a workaround so far and it remains understandable to users:
<img width="241" height="154" alt="image" src="https://github.com/user-attachments/assets/9496f925-8524-4434-8486-dc579442d688" />

## What's next?
Features that could be added:
- Check for lintrunner updates, auto-update if needed
- Depending on dev response, this could be enabled by default for all pytorch/pytorch environments

Subject: [PATCH 0244/1424] [ROCm] Add torch/_rocm_init.py to .gitignore.
 (#159806)

Follow-up to https://github.com/pytorch/pytorch/pull/155285.

Build scripts like https://github.com/ROCm/TheRock/blob/main/external-builds/pytorch/build_prod_wheels.py generate this file with contents like:

```python
def initialize():
    import rocm_sdk
    rocm_sdk.initialize_process(
        preload_shortnames=['amd_comgr', 'amdhip64', 'hiprtc', 'hipblas', 'hipfft', 'hiprand', 'hipsparse', 'hipsolver', 'hipblaslt', 'miopen'],
        check_version='7.0.0rc20250804')
```

We may also have https://github.com/pytorch/pytorch/blob/main/tools/amd_build/build_amd.py do the same thing as more of that build support moves here into the upstream PyTorch repository itself (see https://github.com/pytorch/pytorch/issues/159520).

This file is then loaded if present here: https://github.com/pytorch/pytorch/blob/a7f3bdf550635c796e53442375477efe98fe5447/torch/__init__.py#L145-L157

Given that the file is generated by build scripts, I think adding it to `.gitignore` makes sense, as that will prevent accidental check-ins and keep local history cleaner.

Subject: [PATCH 0245/1424] [ROCm][Windows] Revert copying hipblaslt and
 rocblas dirs. (#159083)

This reverts the changes from https://github.com/pytorch/pytorch/commit/b367e5f6a6c5853d0206bfd43d8b4a7cb76704f1. This will also close https://github.com/pytorch/pytorch/pull/158922.

Since https://github.com/pytorch/pytorch/commit/30387ab2e485384ab2e67084a1e2c5569190ba92, ROCm is bootstrapped using the 'rocm' Python module which contains these files (see https://github.com/ROCm/TheRock/blob/main/docs/packaging/python_packaging.md), so they do not need to be bundled into torch/lib.

There was also a bug in here - if `ROCM_DIR` is unset, the code crashes:
```
  File "D:\projects\TheRock\external-builds\pytorch\.venv\Lib\site-packages\setuptools\_distutils\dist.py", line 1002, in run_command
    cmd_obj.run()
  File "D:\b\pytorch_main\setup.py", line 853, in run
    rocm_dir_path = Path(os.environ["ROCM_DIR"])
                         ~~~~~~~~~~^^^^^^^^^^^^
  File "<frozen os>", line 714, in __getitem__
KeyError: 'ROCM_DIR'
```
The code could have checked for `ROCM_PATH` too.

Subject: [PATCH 0247/1424] Get tensor subclasses and torch.library.triton_op
 to dispatch correctly (#160341)

Short-term fix for https://github.com/pytorch/pytorch/issues/160333

The problem is:
1) `triton_op` adds a decomposition for FunctionalTensorMode for this operation
2) Tensor Subclasses rely on FunctionalTensorMode's `__torch_dispatch__` returning NotImplemented.
3) `triton_op`'s FunctionalTensorMode decomposition takes precedence over FunctionalTensorMode's decomposition.

The easy fix is to copy-paste the FunctionalTensorMode's NotImplemented
return logic into the decomposition.

Subject: [PATCH 0248/1424] [CI] Move CUDA tests to trunk workflow (#160379)

Which is getting run before PR is merged anyway, but according to 3X
less frequently than pull workflow according to [Flambeau](https://pytorchci.grafana.net/public-dashboards/1c571e79090443eaaa9811db71f8d23b)
<img width="796" height="573" alt="image" src="https://github.com/user-attachments/assets/0235e610-4e1c-4be5-88bf-ea8278d1c656" />

I.e. that will probably results in some longer time to signal, but considering that frequency of changes to eager PyTorch-on-CUDA slowed down and Inductor changes are decorated with ciflow/inductor, this looks like an acceptable tradeoff to reduce costs

Subject: [PATCH 0249/1424] [Graph Partition] Pass all OSS unit tests (#154667)

Graph partition leads to 6.2% speedup on vision_maskrcnn, 5.8% speedup on yolov3. [P1819700563](https://www.internalfb.com/phabricator/paste/view/P1819700563), 39.5% speedup on speech_transformer inference [P1830602200](https://www.internalfb.com/phabricator/paste/view/P1830602200), 85% speedup on speech_transformer training [P1831115315](https://www.internalfb.com/phabricator/paste/view/P1831115315).

Run the same diff on two days and both show speedup on average.

+//
+// Why is this global?
+// -------------------
+// * CPython allows only a small, fixed number of dict-watcher IDs (≈64).
+//   All `GuardManager`s therefore share a single watcher callback.
+// * Different guard managers (possibly across different frames) can end up
+//   watching the same dictionary pointer. Therefore, we have a list of guard
+//   managers for each dict pointer.
+//
+// When is watch registered?
+//  * During the recording phase of recursive dict tag matching in GuardManager.
+//
+// When are they watched?
+//  * In the dict_recursive_tag_watch_callback function.
+//
+// When are the dict pointers unwatched?
+//  * If a dict is mutated or the guard manager deallocates.
+//  * Read `unwatch_all_saved_dict_pointers` docstring for more details.
+//
+// Expected size
+// -------------
+// Every compilation frame contributes its tag-safe dicts to this registry, so
+// the container can grow large over the lifetime of the process.  That’s
+// acceptable: lookup is by pointer (hash/equals = identity) and each entry
+// stores only lightweight pointers.

Subject: [PATCH 0261/1424] Account for triton kernel source code hidden in
 custom ops properly in AOTAutogradCache (#160120)

This PR fixes a bug where user defined triton kernels hidden behind `triton_op` do not register source code changes. If a user *only* changes a triton kernel source_code, because triton kernels are hidden under the custom op, dynamo hasn't traced into them yet.

This means at AOTAutograd time, we don't know the list of triton kernels that are defined by custom ops. This is an initial fix for the issue by parsing the AST of the custom op looking for triton kernels. This won't catch more degenerate cases if the custom op calls other custom ops/functions that then call triton kernels, and then the toplevel compiled graph doesn't know about it. To handle that, we'd have to trace through the custom op at dynamo time.

This should handle 99% of cases, though. I added an expectedFailure test to show the limitation.

Reverted https://github.com/pytorch/pytorch/pull/160183 on behalf of https://github.com/clee2000 due to I'm not sure how, but it seems to have broken inductor/test_extension_backend.py::ExtensionBackendTests::test_open_device_registration [GH job link](https://github.com/pytorch/pytorch/actions/runs/16911267995/job/47917091939) [HUD commit link](https://hud.pytorch.org/pytorch/pytorch/commit/7fbc22855c17741ae016992803b2e147a13aa22d).

Subject: [PATCH 0266/1424] [ROCm] Support large inputs for
 coalesceValuesKernel (#158281)

# Description

`.coalesce` cannot handle large inputs on ROCM due to maximal grid size limit.

This PR splits axis `X` into axes `X` and `Y`, and repurposes `Z` for original `Y` on ROCm to avoid such limitation.

Confirmed the new approach can handle large inputs. Correctness needs validation.

# Testing Command

`python torch_spmv.py 22500000 272500000`

## Script `torch_spmv.py`

``` python
import torch
import argparse

def parse_args():
    parser = argparse.ArgumentParser(
        description="Sparse COO Matrix by Dense Vector Multiplication using PyTorch"
    )
    parser.add_argument("n", type=int, help="Size of the NxN matrix")
    parser.add_argument("nnz", type=int, help="Number of non-zero entries")
    return parser.parse_args()

def main():
    args = parse_args()
    n = args.n
    nnz = args.nnz
    dtype = torch.float32
    device = torch.device('cuda')

    # Generate random indices for the sparse matrix in COO format.
    torch.manual_seed(42)
    rows = torch.randint(0, n, (nnz,), dtype=torch.int64, device=device)
    cols = torch.randint(0, n, (nnz,), dtype=torch.int64, device=device)
    indices = torch.stack([rows, cols], dim=0)

    # Generate random values.
    values = torch.randn(nnz, dtype=torch.float32, device=device)

    # Create the sparse COO matrix and move it to the target device.
    sparse_matrix = torch.sparse_coo_tensor(indices, values, size=(n, n), dtype=torch.float32, device=device)
    sparse_matrix = sparse_matrix.coalesce()

    # Generate a random dense vector.
    dense_vector = torch.randn(n, dtype=torch.float32, device=device)

    # Perform sparse matrix - dense vector multiplication.
    # Using torch.sparse.mm which expects a 2D tensor for the vector.
    result = torch.sparse.mm(sparse_matrix, dense_vector.unsqueeze(1)).squeeze()
    # result = torch.mv(sparse_matrix, dense_vector)

    # Print the result.
    print("Result of the multiplication:")
    print(torch.sum(result))

if __name__ == "__main__":
    main()

Subject: [PATCH 0268/1424] [inductor] remove no_x_dim (#159810)

no_x_dim is used to indicate that a reduction operates on a single row, and data loaded for the reduction is 1-dimensional.

no_x_dim was introduced in https://github.com/pytorch/pytorch/pull/102444 - in which there was bad perf in some reductions, and using 1D tensors fixed the perf issue.

However, it appears that this perf issue no longer exists in current Triton versions. https://github.com/pytorch/pytorch/pull/118822 checked this, and we can also check this on H100 benchmarks (linked below). And another motivation for removing this behavior is that it enables larger loads, which we observe is necessary for good performance on certain shapes on Blackwell.

H100 inference benchmarks:
https://hud.pytorch.org/benchmark/compilers?dashboard=torchinductor&startTime=Mon%2C%2004%20Aug%202025%2004%3A13%3A24%20GMT&stopTime=Mon%2C%2011%20Aug%202025%2004%3A13%3A24%20GMT&granularity=hour&mode=inference&dtype=bfloat16&deviceName=cuda%20(h100)&lBranch=gh/davidberard98/396/orig&lCommit=a6bcd4692fb39fa2fad260f290bff545d4425829&rBranch=main&rCommit=e96c7c4bb0f6aeae2ab3b6f040f7d67edbec199a

H100 training benchmarks:
https://hud.pytorch.org/benchmark/compilers?dashboard=torchinductor&startTime=Mon%2C%2004%20Aug%202025%2004%3A13%3A24%20GMT&stopTime=Mon%2C%2011%20Aug%202025%2004%3A13%3A24%20GMT&granularity=hour&mode=training&dtype=amp&deviceName=cuda%20(h100)&lBranch=gh/davidberard98/396/orig&lCommit=a6bcd4692fb39fa2fad260f290bff545d4425829&rBranch=main&rCommit=e96c7c4bb0f6aeae2ab3b6f040f7d67edbec199a

Overall, the benchmarks show minimal change in performance.

Subject: [PATCH 0269/1424] [ROCm]  Use opportunistic fastatomics based on
 hueristics (#159430)

* Opportunistic fast atomics works better with small sizes, since there is more chance of lanes doing atomics on the same address

Co-author: @amd-hhashemi

Reproducer:
```
import time
import torch

x = torch.randn((1_632_960, 128), device='cuda', dtype=torch.float)
ind = torch.randint(0, x.size(0), size=(5_079_670,), device='cuda')
src = torch.randn((5_079_670, 128), device='cuda', dtype=torch.float)

for _ in range(20):
    x.index_add_(0, ind, src)

start_time = time.time()
for i in range(100):
    x.index_add_(0, ind, src)
torch.cuda.synchronize()
end_time = time.time()
mean_time = (end_time - start_time)/100
print(f"Avg time for index_add_: {mean_time * 1e6:.2f} us")
```

Perf numbers:
```
Before:
Avg time for index_add_: 25652.16 us

After:
Avg time for index_add_: 2675.15 us
```

Subject: [PATCH 0275/1424] Support NUMA Binding for Callable Entrypoints
 (#160163)

# Context
This is an extension of #149334.

# This PR
Add support for NUMA bindings with Callable entrypoints, such as `do_train` instead of `/usr/local/bin/python`.

Most notably, we utilize a hack in order to force `Process.start()` to use custom NUMA bindings for each subprocess. Please search for `HACK:` in the code to see a description of the implementation we chose, and #160006 for discussion of alternatives and why this is necessary.

Other changes:
* Remove unnecessary `--preferred` option from all binding strategies. By default, Linux already allocates memory to the NUMA node local to the CPU which triggered the allocation. (See [MPOL_LOCAL](https://man7.org/linux/man-pages/man2/set_mempolicy.2.html).)
* Refactor so that the main API is `maybe_wrap_command_with_numa_bindings`, which computes bindings for a single rank at a time, rather than `maybe_wrap_with_numa_bindings` which computed bindings for all ranks at once. This allowed for more code sharing between `Callable` and `str` entrypoints.

# Test Plan
## Automated
`$ pytest test/test_numa_binding.py`

## Manual
Using [this benchmark,](https://gist.github.com/pdesupinski/bbe01ade455d86e989794f2c612e2d91), ran

```
$ PYTHONUNBUFFERED=1 LOGLEVEL=INFO perf stat -e ls_dmnd_fills_from_sys.dram_io_far,ls_dmnd_fills_from_sys.dram_io_near -- python -m torch.distributed.run --standalone --nproc-per-node=8 --numa-binding=node --run-path mlp_train.py 2>&1 | tee node_callable.txt && PYTHONUNBUFFERED=1 LOGLEVEL=INFO perf stat -e ls_dmnd_fills_from_sys.dram_io_far,ls_dmnd_fills_from_sys.dram_io_near -- python -u -m torch.distributed.run --standalone --nproc-per-node=8 --run-path mlp_train.py 2>&1 | tee none_callable.txt
```

and observed
* 6.6% remote memory accesses with 'node' bindings
* 11.6% remote without bindings

I also ran similar with `str` entrypoints as before just to be sure it's still working.

NOTE: [--run-path triggers the code to be run inside a `Callable`.](https://github.com/pytorch/pytorch/blob/017259f9c65b6fad55fb9597d7077e2543eaae46/torch/distributed/run.py#L870)

Subject: [PATCH 0276/1424] Add ownership token when needed on GradientEdge
 (#160098)

We can avoid the token by introducing PyObject preservation for THPFunction. But I think it will be too much complexity given that this kind of issue is very rare.
Happy to be talked into doing it though if someone really wants to.

Subject: [PATCH 0277/1424] Remove usage of fsspec in HF consolidation script
 (#159392)

Moving towards just supporting local storage to take advantage of HF apis such as safe_open. This was already done in Storage component in https://github.com/pytorch/pytorch/pull/159405. This PR removes fsspec usages in consolidation script and relies on local storage only

Subject: [PATCH 0278/1424] added class or module info for functions blocked by
 weight-only load (#159935)

Fixes #152985
In #152985, users are confused why weights-only load failed even though functions were registered in safe_globals.
Because the error message doesn't make the critical failure reason clear, they couldn't figure out only some functions are missing from safe_globals registration.
This fix is to make that point more clear.

Here's the new errror message, the blocked function information will be following the warning message with a line breaker to make it stand out.
```
_pickle.UnpicklingError: Weights only load failed. In PyTorch 2.6, we changed the default value of the `weights_only` argument in `torch.load` from `False` to `True`. Re-running `torch.load` with `weights_only` set to `False` will likely succeed, but it can result in arbitrary code execution. Do it only if you got the file from a trusted source.
Please file an issue with the following so that we can make `weights_only=True` compatible with your use case: WeightsUnpickler error:

Trying to call reduce for unrecognized function <built-in method _unpickle of type object at 0x641e8a57d1f0> which belongs to <class 'zoneinfo.ZoneInfo'>

Check the documentation of torch.load to learn more about types accepted by default with weights_only https://pytorch.org/docs/stable/generated/torch.load.html.

To execute this test, run the following from the base repo dir:
    python test/test_serialization.py TestSerialization.test_weights_only_with_safe_zoneinfo_unpickle_registration_success

This message can be suppressed by setting PYTORCH_PRINT_REPRO_ON_FAILURE=0

```

Subject: [PATCH 0280/1424] [DTensor] Registers sharding rule for rms_norm
 (#159692)

Reduces collective calls in the forward pass from 2 to 1

In #158716 I added the sharding rule for the backward pass but didn't add the forward pass as it didn't get dispatched. After #159324 this should get properly dispatched hence I am adding it now.

Subject: [PATCH 0281/1424] [FSDP][Collectives] skipping allgather when world
 size is 1 (#160135)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Summary:** In its current state, FSDP collectives uses cuda synchronizations and communication ops regardless of what the world size is. However, now that replicate will use FSDP, there will be instances where group size = 1 and these synchronizations and ops will be used needlessly. I have updated fsdp_params group to skip the foreach_all_gather and foreach_all_gather_copy_out APIs when world_size ‎ = 1. I have created a test that uses CommDebugMode to verify that the all gather comm has been removed. I also edited an affected test which used 1-way FSDP by verifying and changing its assert statements for CommDebugMode. Below, I have included the link to the profile trace verifying these two APIs were skipped and two test commands.

Subject: [PATCH 0282/1424] [ROCm] Limit number of values per thread for
 reductions on three dimensions (#159652)

In the current implementation of reductions in three dimensions for AMD GPUs the number of values per thread is unbounded and can end up being in the hundreds of thousands for certain tensors. This of course is bad for performance. This patch fixes this issue by increasing the parallelism and thus lowering the number of value per thread to reasonable limits i.e. less than 2048 values per thread. The performance gains can be between 10x-17x for certain examples where the number of values per thread was originally very high.

Subject: [PATCH 0283/1424] Update torch::stable::Tensor() default constructor
 (#159507)

Allows things like

```cpp
Tensor cu_seqlens_q;
if (...) {
   cu_seqlens_q = ...
}
...
```

Also adds `torch::stable::Tensor.defined()`

Subject: [PATCH 0285/1424] fix cpp builder to avoid missing-source compile
 error (#160354)

Summary:
the condition
```
if config.is_fbcode() and (not self._aot_mode or self._use_relative_path):
    sources = [os.path.basename(i) for i in sources]
```
unintentionally (?) stripped paths even when use_relative_path was False (as long as aot_mode was False), breaking local tests that rely on absolute temp-file paths.

Fixes internal issue:
```

Subject: [PATCH 0286/1424] [TorchScript] thread-safe ErrorReport::CallStack
 (#160386)

Context: During jit.script, the TorchScript frontend maintains a callstack of Python frames, which is used to present the corresponding user code in case TorchScript errors. The callstack is maintained via ErrorReport::CallStack RAII guards. Before recursing into a function, an ErrorReport::CallStack guard is created and the CallStack guard pushes the frame information onto a thread_local callstack (a list of calls); and after exiting, the frame information is popped off the callstack. Note that the CallStack guards are also sometimes used in python via pybindings.

The problem is that sometimes another thread can obtain a reference to the CallStack guard (if it's a Python CallStack guard). **This means that the destructor for a CallStack guard can be called from a different thread than the constructor was called**. When this happens, it causes a segfault.

This PR makes the callstack vector thread-safe to access, and each CallStack guard will store a reference to the callstack vector onto which it pushed. When the CallStack guard is destructed, it pops off the appropriate callstack vector. Although this could potentially lead to mangled callstacks, it should prevent segfaults.

Added a test `test_thread_safe_error_stacks` which segfaults prior to these changes, and no longer segfaults.

which is unexpected. After asking claude, it seems

> Now I can see the issue. The `CppCompileError` class requires two arguments: `cmd` (a list of strings) and `output` (a string). However, when exceptions are being pickled and unpickled across process boundaries, the pickling process might not be preserving the constructor arguments correctly.
>
> The problem is likely that when a `CppCompileError` is raised in the subprocess and then pickled/unpickled through the `recv` function, the unpickling process is trying to reconstruct the exception but doesn't have the required constructor arguments.
>
> The issue is clear now. The `CppCompileError` class doesn't have custom pickle methods (`__reduce__`, `__getstate__`, `__setstate__`), so when it's pickled and unpickled across process boundaries, Python's default pickling mechanism tries to reconstruct it but fails because it doesn't preserve the constructor arguments properly.
>
> The solution is to add a `__reduce__` method to the `CppCompileError` class to ensure it can be properly pickled and unpickled. Let me implement this fix:

Adding these seem to help.

Subject: [PATCH 0289/1424] Fullgraph graph capture with dynamo. (#159749)

Summary:
Following up on Avik's doc https://docs.google.com/document/d/11RW0Bbkp1QwFbEu8rCNW5d7wUFaEkxbL0uLyqcc2jTk/edit?tab=t.0

We are experimenting with a new API which utilizes torch.compile(fullgraph=True) and intend to use it to replace the old dynamo.export() API.

This PR adds a prototype for the API described in the doc.

Test Plan:
test_misc -- -k test_aot_capture

Rollback Plan:

Subject: [PATCH 0291/1424] [CI] Switch ROCm MI300 GitHub Actions workflows
 from 2-GPU to 1-GPU runners (#158882)

Updated .github/actionlint.yaml to replace linux.rocm.gpu.mi300.2 with linux.rocm.gpu.mi300.1 in the supported runner list

Modified all affected workflows (inductor-perf-test-nightly-rocm.yml, inductor-periodic.yml, inductor-rocm-mi300.yml, and rocm-mi300.yml) to run jobs on 1-GPU MI300 runners instead of 2-GPU runners

This should help increase available runners even with same number of CI nodes.

Subject: [PATCH 0292/1424] [EZ] Replace `pytorch-labs` with `meta-pytorch`
 (#160459)

This PR replaces all instances of 'pytorch-labs' with 'meta-pytorch' in this repository now that the 'pytorch-labs' org has been renamed to 'meta-pytorch'

## Changes Made
- Replaced all occurrences of 'pytorch-labs' with 'meta-pytorch'
- Only modified files with extensions: .py, .md, .sh, .rst, .cpp, .h, .txt, .yml
- Skipped binary files and files larger than 1MB due to GitHub api payload limits in the script to cover all repos in this org. Will do a more manual second pass later to cover any larger files

## Files Modified
This PR updates files that contained the target text.

Subject: [PATCH 0293/1424] [c10d] Error out the case when registering
 symmetric memory without eager init (#160145)

Instead of implicitly creating nccl comm inside mem pool registration for symmetric memory, we decide to error it out so that we only support eager init case when the nccl comm is already initiated.

Subject: [PATCH 0296/1424] [Inductor][Triton] Pass GPUTarget param to updated
 make_ir function (#160422)

Summary: A recent Triton commit changed `ASTSource.make_ir` to a 5-arg signature that includes a `GPUTarget`. We need to pass in this new argument.

Test Plan:
`buck2 test 'fbcode//mode/opt' -m ovr_config//triton:trunk  fbcode//caffe2/test/inductor:test_inductor_cuda -- triton_kernel`

Subject: [PATCH 0298/1424] Avoid potential deadlocks in host allocator
 (#159352)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Motivation
This PR fixes a potential deadlock in the host allocator.
When calling `event->record(stream)`, the `record_stream` implementation may acquire the Python GIL.
In places such as https://github.com/pytorch/pytorch/blob/842cc77ab9aafd518593c2fce077d6abb42a5b7f/aten/src/ATen/cuda/CachingHostAllocator.cpp#L145-L151, and https://github.com/pytorch/pytorch/blob/842cc77ab9aafd518593c2fce077d6abb42a5b7f/aten/src/ATen/xpu/CachingHostAllocator.cpp#L22-L28 `record_stream` is invoked while holding the allocator lock.

To prevent deadlocks, we must ensure the locking order is:
**GIL → Allocator Lock**.
Reversing the order (**Allocator Lock → GIL**) can cause a deadlock.

 (#160258)

After some debug work, I found PyTorch torch_cpu.dll is using intel-openmp, but not MSVC openmp.
So, switch Windows inductor to intel-openmp.

It fixed: https://github.com/pytorch/pytorch/blob/c8205cb35435f39d2c26f6c94b45e4adeb6dcb23/test/inductor/test_aot_inductor.py#L2405-L2408

Subject: [PATCH 0301/1424] Add new function
 consolidate_safetensors_files_on_every_rank for HF consolidation (#159393)

Currently we are only using rank-0 for HF consolidation. But we should be able to use every rank to consolidate the sharded files, which will speed up the consolidation by Nx (where N is the number of ranks). Adding a new method consolidate_safetensors_files_on_every_rank to do this.

Differential Revision: [D79000720](https://our.internmc.facebook.com/intern/diff/D79000720/)

Pull Request resolved: https://github.com/pytorch/pytorch/pull/159393

Subject: [PATCH 0305/1424] [GHF] Remove `app { name databaseId}` query
 (#160494)

From `PRCheckSuites` fragment, as it's causes security exception when used with new GITHUB_TOKEN, that will looks as follows
```

```
But the same query works fine if executed using one's Personal Access Token

Updated mocks file by running
```

Subject: [PATCH 0306/1424] Write full tensors out at once in HF consolidation
 script (#159394)

Not all storage systems support writing at random offsets. This PR changes the writes of the consolidation script to write each tensor to a buffer, and then write out the buffer, sequentially going through every tensor in the output file. This will also help in the case where the sharded files weren't just sharded in the row-wise dimension. The reason is because small writes are expensive and we were writing each write for every chunk that was the largest number of contiguous bytes in the final tensor, but this could be a small amount of bytes for col-wise sharding. Now the full tensor is needed for the write, making the number of small writes smaller.

Subject: [PATCH 0308/1424] [CD] Do not build pytorch with nvshem on ARM
 (#160465)

As nvshmem binary from 3.3.9 is not compatible with manylinux2_28, and 3.3.20 is not available for download yet
Also, package nvshmem binary into full wheel

Subject: [PATCH 0314/1424] Add `compile_id: Optional[CompileID]` to
 `torch._logging._internal.trace_structured_artifact` (#160440)

Context:
When writing a custom `torch.compile` backend, I quite frequently (ab)use `trace_structured_artifact` because I'm too lazy to customize tlparse (ref: https://github.com/Lightning-AI/lightning-thunder/pull/2182/commits/6d8b13c867f6f2afdfb03636e55f93b4e26e9518).

I recently notice some of the artifacts I want to store are generated where CompileID cannot be correlated and `tlparse` html says
> Sometimes, logs are made without a compile id. This makes it difficult to correlate related logs. This stack trie shows all places where log entries occurred without compile context; to fix, look an appropriate place in the stack where compile id should have been specified.

+DTensor operator schema definitions and utilities.
+
+This module defines the core data structures and utilities for describing and managing
+distributed tensor operations in PyTorch's DTensor system. It provides the foundational
+schema types used for sharding propagation, operator strategy selection, and distributed
+execution planning.
+
+Key components:
+- OpSpec: Describes acceptable sharding placements for operations
+- OpStrategy: Represents the possible sharding strategies for an operator
+- TupleStrategy: Container for multiple strategies when ops have tuple/list of tensors input
+- OpSchema: Describes operator input/output schemas with DTensorSpecs
+- OutputSharding: Manages output sharding specifications and redistribution
+- RuntimeSchemaInfo: Runtime execution metadata for operators
+- OpInfo: Complete runtime operator execution information
+
+These schema definitions enable the DTensor system to:
+1. Propagate tensor sharding information to the operator outputs
+2. Greedily select sharding strategies for distributed operations
+3. Plan and execute tensor redistributions when needed
+4. Cache sharding decisions for performance optimization

Subject: [PATCH 0318/1424] port 3 distributed test to Intel GPU and unified
 some common functions (#158533)

For https://github.com/pytorch/pytorch/issues/114850, we will port distributed tests to Intel GPU.
We could enable Intel GPU with following methods and try the best to keep the original code styles:

- instantiate_device_type_tests()
- use "torch.accelerator.current_accelerator()" to determine the accelerator backend
- enabled XPU for some test path
- Unify some common code under torch/testing/_internal for multiple backend, for example:
  - requires_nccl_version
  - _dynamo_dist_per_rank_init
  - DynamoDistributedSingleProcTestCase
  - DistTestCases
  - FSDPTestMultiThread

Subject: [PATCH 0320/1424] [Dynamo][Hierarchical Compile] Allow parameters to
 be propagated to submodules (#157979)

Fixes issue with HF Gen AI models where we mark a param as static and a get_attr node gets put in the region.

The effect of this is lifting get_attr nodes to be inputs.

Subject: [PATCH 0321/1424] [Hierarchical Compile] Sort all regions identically
 (#158814)

Before we would topologically sort each region individually, this works well except if some nodes have no arguments, then their order may change. To rectify this, we sort the first region as the reference region and use that sort order to sort the remaining regions.

Subject: [PATCH 0322/1424] Fix get_free_symbol_uses for several nodes
 (#160314)

get_free_symbol_uses is used to know what unbacked symbols are used by a given node.
not having correct get_free_symbol_uses defined properly leads to :

- eliminating of some nodes due to not detection of any users. (See the added unit test)
- Incorrect topological sort.

Fix get_free_symbol_uses , NopKernel , ConcarKernel, InputsKerenl, external kernel.
for ComputedBuffer with NonOwningLayout its interesting case.
when layout is NonOwningLayout we need to access the actual view op base layout and use
detect symbols in it. Because when we codegen the ComputedBuffer we uses those symbols.

Subject: [PATCH 0324/1424] [1/N]Port 3  distributed/_tools test cases to Intel
 GPU (#159543)

For [#114850](https://github.com/pytorch/pytorch/issues/114850), we will port distributed tests to Intel GPU.

We could enable Intel GPU with following methods and try the best to keep the original code styles:

1. use "torch.accelerator.current_accelerator()" to determine the accelerator backend
2. enabled XPU for some test path
3. skip some test cases which Intel GPU does not support

+# PyTorch Main Components
+
+PyTorch is a flexible and powerful library for deep learning that provides a comprehensive set of tools for building, training, and deploying machine learning models.
+
+## PyTorch Components for Basic Deep Learning
+
+Some of the basic PyTorch components include:
+
+* **Tensors** - N-dimensional arrays that serve as PyTorch's fundamental
+data structure. They support automatic differentiation, hardware acceleration, and provide a comprehensive API for mathematical operations.
+
+* **Autograd** - PyTorch's automatic differentiation engine
+that tracks operations performed on tensors and builds a computational
+graph dynamically to be able to compute gradients.
+
+* **Neural Network API** - A modular framework for building neural networks with pre-defined layers,
+activation functions, and loss functions. The {mod}`nn.Module` base class provides a clean interface
+for creating custom network architectures with parameter management.
+
+* **DataLoaders** - Tools for efficient data handling that provide
+features like batching, shuffling, and parallel data loading. They abstract away the complexities
+of data preprocessing and iteration, allowing for optimized training loops.
+
+
+## PyTorch Compiler
+
+The PyTorch compiler is a suite of tools that optimize model execution and
+reduce resource requirements. You can learn more about the PyTorch compiler [here](https://docs.pytorch.org/docs/stable/torch.compiler_get_started.html).

 better editor integration (#160357)"

This reverts commit cbffde774557752cf20447d42d99ec6102673c31.

Reverted https://github.com/pytorch/pytorch/pull/160357 on behalf of https://github.com/clee2000 due to broke a bunch of internal builds due to not being able to find the file  No such file or directory: torch/_inductor/kernel/flex/templates/flex_decode.py.jinja D80145761, might need a buck targets change?

Hi, @malfet
Based on the previous discussion:

[RISCV CI support · Issue #141550 · pytorch/pytorch](https://github.com/pytorch/pytorch/issues/141550)

I have cross-compiled PyTorch for the RISC-V architecture on x86_64 Ubuntu 24.04 and created a new PR for it. Could you please help review it?

Subject: [PATCH 0332/1424] [DCP][OSS] Rank local checkpointing in DCP without
 collectives (#147758)

Summary:
DCP metadata collectives become prohibitively expensive as the job scale grows. This PR introduces rank-local checkpointing which basically saves and loads the checkpoint without any collective. The trade off for now is the dedupe and re-sharding. Support for these would be introduced soon.

Differential Revision: D70112642

Subject: [PATCH 0336/1424] Do not rpath CUDA stubs folder in JIT generated
 code (#160179)

`_transform_cuda_paths` intentionally includes the CUDA stubs folder.

However this path must not be added to the rpath as otherwise any CUDA command will fail at runtime with
> CUDA_ERROR_STUB_LIBRARY: "CUDA driver is a stub library"

This results in e.g. non-descriptive errors like
```
cutlass_library/source/tools/util/include/cutlass/util/device_memory.h:67  cutlass::device_memory::allocate: cudaMalloc failed: bytes=4096
terminate called after throwing an instance of 'cutlass::cuda_exception'
  what():  std::exception

Subject: [PATCH 0342/1424] [cutlass backend] Allow bmm use cases when batch
 stride is 0 (#160356)

Differential Revision: [D80035771](https://our.internmc.facebook.com/intern/diff/D80035771/)

The motivation and the original change is to reduce the number parameters we pass into the kernel, which was motivated by aesthetic reasons only.

But seeing the need to use different batch stride, we should just pass in the batch stride. That would be a good long term fix.

Subject: [PATCH 0343/1424] Add utility to get computed kernel in torch.library
 (#158393)

Adds `OperatorEntry::getComputedKernelForDispatchKey` which returns the KernelFunction corresponding to `OperatorEntry.dispatchTable_[dispatch_ix]` for a given dispatch key
- Specifically it returns a `SafeKernelFunction` that holds a `KernelToken`. This `KernelToken` is registered to the `KernelFunction` in `OperatorEntry.kernels_` and will be invalidated when the `KernelFunction` is destructed (i.e. when the `AnnotatedKernel` that holds this `KernelFunction` is removed from `kernels_`, which happens when the corresponding impl is deregistered).
- `SafeKernelFunction` can be called via `callBoxed`, the validity of the token will be checked before this happens
- `SafeKernelFunction` is pybinded and `getComputedKernelForDispatchKey` is exposed to the frontend ia `torch.library.get_kernel`

Related to https://github.com/pytorch/pytorch/issues/155330

Subject: [PATCH 0344/1424] Change IR node's stack trace to be computed lazily
 (#160487)

Summary: When an IR node is an inherited class, post_init is called once for each super().__init__() call. To avoid duplicated calls, we make stack trace computation happen lazily.

Test Plan:
CI

Subject: [PATCH 0346/1424] [MTIA-T][CFF] Pass backend parameter into GPU
 vertical pass file and pattern matcher (#160404)

Summary:
As titled
Please see https://fb.workplace.com/groups/1075192433118967/posts/1735215827116621/?comment_id=1735220747116129&reply_comment_id=1735242997113904

Basically, for MTIA, we want mtia_afg to show up in the counters and backend, instead of Inductor. MTIA is not using inductor yet. Using env var TORCHINDUCTOR_PATTERN_MATCH_BACKEND to pass in the actual backend.

The env var default value is "inductor", so nothing should break for GPU.

Test Plan:
Default is always "inductor", so existing test should not break.

CI tests

Rollback Plan:

Subject: [PATCH 0349/1424] [C10D] Add check_rng_sync util (#160283)

Debugs RNG desync by checking the current state on each rank in the group and summarizing the differences if any are detected.

Notes:
- used allgather instead of gather since its simpler to do this SPMD rather than add conditional behavior, though I could be convinced we only want to log on rank0.

Usage:
`check_rng_sync(generator, group)`

Prints something like this:

(cuda):
```
[rank0]:E0808 ] Generator desync detected:
[rank0]:E0808 ] Ranks    (Seed, Offset) values
[rank0]:E0808 ] -------  -----------------------
[rank0]:E0808 ] 0        (456, 0)
[rank0]:E0808 ] 1        (123, 4)
[rank0]:E0808 ] 2-3      (123, 0)
```

(cpu):
```
[rank2]:E0810 ] Generator desync detected:
[rank2]:E0810 ] Ranks      Generator State Hash values
[rank2]:E0810 ] -------  -----------------------------
[rank2]:E0810 ] 0                  7633364531954955665
[rank2]:E0810 ] 1                  8807615394212033278
[rank2]:E0810 ] 2-3               -6150027303226666531
```

Subject: [PATCH 0350/1424] Fix unit test test_equivalent_template_code
 (#160432)

Summary:
Fix unit test test_equivalent_template_code

https://github.com/pytorch/pytorch/pull/159920 treats  ReinterpretView as a not-realized node when searching FX origin nodes for fused triton kernel. In test_equivalent_template_code, there is a transpose node (which is a ReinterpretView) before matmul. It was not in FX graph segment before PR 159920. FX origin nodes are used to define the name of triton kernel. That is the reason test_equivalent_template_code failed with PR 159920 since it uses hard-coded triton kernel name to check the result. The fix is to update the triton kernel name in the unit test.

Test Plan:

Subject: [PATCH 0352/1424] Add beginnings of torch::stable::accelerator
 (#159679)

Adds
- `torch::stable::accelerator::DeviceGuard`: `std::unique_ptr` to `DeviceGuardOpauqe` mostly copied from the below (but made generic)

   https://github.com/pytorch/pytorch/blob/50eac811a68e63e96ad56c11c983bfe298a0bb8a/torch/csrc/inductor/aoti_runtime/utils_cuda.h#L30-L46
    - constructor `DeviceGuard(DeviceIndex)` (**this matches aoti but defers from the actual c10 DeviceGuard constructor that takes in device**)
    - `set_index(DeviceIndex)`
- `torch::stable::accelerator::Stream`: `std::shared_ptr` to `StreamOpaque`
     - constructor `Stream(StreamHandle stream)` (similar to torch::stable::Tensor)
     - `id() -> StreamId`

- `getCurrentStream(DeviceIndex device_index) -> stable::accelerator::Stream`

Subject: [PATCH 0354/1424] [MPS] Add API to query GPU core count (#160414)

Using good old IOKit to get `gpu-core-count` property from device implementing `AGXAccelerator` service
Expose this one as `torch.backend.mps.get_core_count()` and make it accessible via `MpsInterface` to the inductor

Test Plan: Run `python3 -c "import torch;print(torch.backends.mps.get_name(), torch.backends.mps.get_core_count())"` and compare it to `system_profiler SPDisplaysDataType|head -n10`
```
% python3 -c "import torch;print(torch.backends.mps.get_name(), torch.backends.mps.get_core_count())"
Apple M1 Pro 16
% system_profiler SPDisplaysDataType|head -n10
Graphics/Displays:

    Apple M1 Pro:

      Chipset Model: Apple M1 Pro
      Type: GPU
      Bus: Built-In
      Total Number of Cores: 16
      Vendor: Apple (0x106b)
      Metal Support: Metal 3
```

This would significantly improve occupancy for torch.compile generated kernels

Subject: [PATCH 0357/1424] finfo eps doc fix (#160502)

Existing documentation for torch.finfo().eps is as below:
| eps             | float  | The smallest representable number such that ``1.0 + eps != 1.0``.          |

Proposed documentation for torch.finfo().eps is as below:
| eps             | float  | The difference between 1.0 and the next smallest representable float larger than 1.0.	|

Fixes #160397

Subject: [PATCH 0364/1424] Add support for param mutation under inference mode
 (#159661)

Summary:
In HF model rwkv, we have parameter mutation under inference mode which should be safe. This PR does multiple things to make sure it works:
1. We execute global autograd mutation while tracing so that we can actually trace through parameter inplace mutation
2. Add support for parameter mutation under inference mode in AOTAutograd
3. Add support for parameter mutation under inference mode in export.

Test Plan:
test

Rollback Plan:

+# 🔧 Lumen_cli
+A Python CLI tool for building and testing PyTorch-based components, using a YAML configuration file for structured, repeatable workflows.
+
+
+## Features
+- **Build**
+    - external projects (e.g. vLLM)
+
+## 📦 Installation
+at the root of the pytorch repo
+```bash
+pip install -e .ci/lumen_cli
+```
+
+## Run the cli tool
+The cli tool must be used at root of pytorch repo, as example to run build external vllm:
+```bash
+python -m cli.run build external vllm
+```
+this will run the build steps with default behaviour for vllm project.
+
+to see help messages, run
+```bash
+python3 -m cli.run --help
+```
+
+## Add customized external build logics
+To add a new external build, for instance, add a new external build logics:
+1. create the build function in cli/lib folder
+2. register your target and the main build function at  EXTERNAL_BUILD_TARGET_DISPATCH in `cli/build_cli/register_build.py`
+3. [optional] create your ci config file in .github/ci_configs/${EXTERNAL_PACKAGE_NAME}.yaml

- VllmBuildRunner:
   - implement logic to prepare and run vllm build with dockerfile
   -

Subject: [PATCH 0372/1424] Remove the dead code in setup.py (#160515)

The following line has no effect.

https://github.com/pytorch/pytorch/blob/34ec5ed275f8aa875c80daa97b3e82af0b06f673/setup.py#L1205

This code was originally introduced in this PR: https://github.com/pytorch/pytorch/commit/dd7cec680cc439af1fd5933b763ab2b963a3f643,
and clang11 and later now support `-fstack-clash-protection`. Can we remove this line?

Subject: [PATCH 0374/1424] Fix wrong log file name in the docs of
 `torch.distributed.elastic.multiprocessing.start_processes()` (#160396)

Fixes #160395

In https://docs.pytorch.org/docs/stable/elastic/multiprocessing.html#starting-multiple-workers and also in the code comment of the function[1], it was specified that:

```
    For each process, the ``log_dir`` will contain:

    #. ``{local_rank}/error.json``: if the process failed, a file with the error info
    #. ``{local_rank}/stdout.json``: if ``redirect & STDOUT == STDOUT``
    #. ``{local_rank}/stderr.json``: if ``redirect & STDERR == STDERR``
```

While in code[2], the files are `stdout.log` and `stderr.log`, instead of the `.json` ones listed in the doc.

Subject: [PATCH 0375/1424] [Intel GPU] Support SDPA backend selection and
 priority setting on XPU (#159464)

Currentlly SPDA XPU use own `priority_order` instead of the one from global context. Hence it does not support `with sdpa_kernel(order, set_priority=True)` with set_priority=True.

This PR enables this feature. To make default `priority_order` from global context works for XPU, I also move MATH backend to lowest priority, otherwise `cudnn attention` and `overrideable attention` will never be selected.

Subject: [PATCH 0380/1424] [cutlass backend] re-add pip cutlass path (#160180)

Revert #156651 to allow using the cutlass PIP package which is easier for users than the Git checkout or similar method.

Also fix a bug where the PIP cutlass path wouldn't be available to subprocesses spawned during benchmarking for algorithm selection. Looks like the "spawn" method does not inherit the (potentially) already set up `config.cuda.cutlass_dir` so in the subprocess the include paths will still be set to `"../third_party/cutlass/"` leading to compilation failure due to missing headers.

Ensure `try_import_cutlass` is called at that point, which due to caching is a no-op in most cases, so doesn't hurt.
Change the logic to return `None` when cutlass isn't available returning more useful values for include paths, namely an empty list. This is in line with other inductor code which disables the CUTLASS backend when `try_import_cutlass` returns False

Subject: [PATCH 0381/1424] [Dynamo] Fix MTIA dynamo backend by avoiding
 has_trition() at import time (#160604)

# Summary
MTIA's torch.compile tests were broken by D80037015. (For details, see internal task T234563969.) The root cause was that `has_triton` can change state after we call `torch.mtia.init()`, but it was used in a way that fixes Inductor's behavior at import time. (Note that `has_triton` is cached, and there's no opportunity to call `torch.mtia.init()` prior to `import torch`.)

To fix this, we use `try: import triton` as opposed to `has_triton()` at the module level.

# Test Plan

See the internal diff. As a follow-up, we will add appropriate unit tests and/or CI hints so this type of issue can be caught at PR/diff time.

Subject: [PATCH 0382/1424] [PP] Add DualPipeV schedule (#159591)

Added the DualPipeV schedule according to http://github.com/deepseek-ai/DualPipe/blob/main/dualpipe/dualpipev.py#L11

<img width="3633" height="486" alt="image" src="https://github.com/user-attachments/assets/4e843bb9-87cd-4d11-936c-7dfe8ee12f16" />

This schedule doesn't perform the actual "overlap" during execution, but provides the scaffolding and schedule definition we need to run it E2E in torchtitan. Supporting the overlapped operation will be worked on in following PRs.

Tests:
```sh
python test/distributed/pipelining/test_schedule_multiproc.py -k test_v_shape_schedules
python test/distributed/pipelining/test_schedule.py -k test_pipeline_order_for_v_schedules
```

Also tested in TorchTitan and is running.

Subject: [PATCH 0384/1424] [ROCm] Support large inputs for
 coalesceValuesKernel (#158281)

# Description

`.coalesce` cannot handle large inputs on ROCM due to maximal grid size limit.

This PR splits axis `X` into axes `X` and `Y`, and repurposes `Z` for original `Y` on ROCm to avoid such limitation.

Confirmed the new approach can handle large inputs. Correctness needs validation.

# Testing Command

`python torch_spmv.py 22500000 272500000`

## Script `torch_spmv.py`

``` python
import torch
import argparse

def parse_args():
    parser = argparse.ArgumentParser(
        description="Sparse COO Matrix by Dense Vector Multiplication using PyTorch"
    )
    parser.add_argument("n", type=int, help="Size of the NxN matrix")
    parser.add_argument("nnz", type=int, help="Number of non-zero entries")
    return parser.parse_args()

def main():
    args = parse_args()
    n = args.n
    nnz = args.nnz
    dtype = torch.float32
    device = torch.device('cuda')

    # Generate random indices for the sparse matrix in COO format.
    torch.manual_seed(42)
    rows = torch.randint(0, n, (nnz,), dtype=torch.int64, device=device)
    cols = torch.randint(0, n, (nnz,), dtype=torch.int64, device=device)
    indices = torch.stack([rows, cols], dim=0)

    # Generate random values.
    values = torch.randn(nnz, dtype=torch.float32, device=device)

    # Create the sparse COO matrix and move it to the target device.
    sparse_matrix = torch.sparse_coo_tensor(indices, values, size=(n, n), dtype=torch.float32, device=device)
    sparse_matrix = sparse_matrix.coalesce()

    # Generate a random dense vector.
    dense_vector = torch.randn(n, dtype=torch.float32, device=device)

    # Perform sparse matrix - dense vector multiplication.
    # Using torch.sparse.mm which expects a 2D tensor for the vector.
    result = torch.sparse.mm(sparse_matrix, dense_vector.unsqueeze(1)).squeeze()
    # result = torch.mv(sparse_matrix, dense_vector)

    # Print the result.
    print("Result of the multiplication:")
    print(torch.sum(result))

if __name__ == "__main__":
    main()
```

Subject: [PATCH 0386/1424] [SymmMem] Check return of nvshmem_malloc (#160603)

`nvshmem_malloc` returns a null pointer when allocation fails. We should check here.
Otherwise, the nullptr can go down the road and into the device kernel, causing CUDA illegal memory access.

Subject: [PATCH 0389/1424]  Add dtype checks in meta dispatch for various
 ordering ops (#159556)

This adds data type checks for the unsupported bool and complex types for argmax/min topk, sort, minimum, maximum. As listed here:

https://github.com/pytorch/pytorch/blob/0a99b026d6bd0f67dc2c0a20fe3228ddc4144854/torch/testing/_internal/common_methods_invocations.py#L21076

Currently the ops will fail on CPU or CUDA calculation, rather than at meta dispatch stage as with for example max: https://github.com/pytorch/pytorch/blob/0a99b026d6bd0f67dc2c0a20fe3228ddc4144854/aten/src/ATen/native/TensorCompare.cpp#L285 . This will catch it early.

Subject: [PATCH 0392/1424] [PP] Allow larger world_size schedule tests
 (#160559)

Update schedule tests to use `world_size=4`, changes needed:
- Move some tests that require world_size=2 to new class
- Move helper methods from class level to function level
- Update some initialization to pass assert since gradients were super small.

Subject: [PATCH 0393/1424] [DTensor] add op support: aten.squeeze_.dim
 (#159532)

**Summary**
This PR enables in-place op `aten.squeeze_.dim` on DTensor with a change to
DTensor dispatch logic: when processing in-place operator, we should assign
`output_sharding.output_spec` back to the first argument. This is because
the in-place op_call on `arg._local_tensor` could also shift the tensor meta.

**Test**
`pytest test/distributed/tensor/test_view_ops.py -s -k  test_squeeze_`

Subject: [PATCH 0394/1424] Allow torch.hub.load with unauthorized GITHUB_TOKEN
 (#159896)

Allow torch.hub.load with unauthorized GITHUB_TOKEN

`torch.hub.load` fails if a `GITHUB_TOKEN` with few permissions is set, as can be seen in the following example. Make sure that the model has not been cached before, for example with `rm ~/.cache/torch`. If the model has been downloaded already, it will not be downloaded again and the authorization error will not occur.

```python
export GITHUB_TOKEN=""
python
>>> import torch
>>> torch.hub.load('facebookresearch/dinov2', 'dinov2_vits14')
Traceback (most recent call last):

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 401: Unauthorized
```

The cause of the error is that the function `_validate_not_a_forked_repo` in `hub.py` always uses `GITHUB_TOKEN` for authorization,  even when downloading does not require authorization.

https://github.com/pytorch/pytorch/blob/0ba09a6d345816483cbca2e8b872c0bd946d822e/torch/hub.py#L194

This fix simply retries the download without the token in case of a failure.

Subject: [PATCH 0398/1424] Set PYTHONHOME for inductor subprocesses using
 torch (#160008)

This is needed for subprocesses that are trying to call back into torch functionality, i.e. anything that's also setting `PYTHONPATH`.  If they're part of an application that bundles the Python runtime, then they should use the bundled runtime to keep their view of the world consistent.

There are more `sys.executable` subprocesses in torch/ but it seems like they're fine.

Previous PR at https://github.com/pytorch/pytorch/pull/159382, but was reverted because it caused macOS jobs on GitHub to timeout.  What was happening was inductor subprocesses were scheduling C++ compilation tasks that were failing to find the Python.h header.  This was because they were running in venvs and now trying to find the CPython headers inside the venv, where the headers do not exist.  This PR gates the new behavior to internal builds only.

Subject: [PATCH 0402/1424] [Inductor] addmm + activation function fusion
 (#158137)

PR implements a pass in post_grad to fuse activation(add + mm)

This was previously done similarly here #106912 but was reverted for performance reasons. it was replaced with a pass that unfuses the activation and add from addmm/addmm_activation and let inductor handle the fusion.

however since then cuBLAS team has made a lot of perf improvements on this, will update this post with more benchmarks but preliminary benchmark show good results

Relu works with both training and inference but gelu only works with inference mode due to some fundamental limitations since gelu's derivative depends on input and relu's doesnt. don't think this is fixable with the current addmm_activation API

Subject: [PATCH 0404/1424] Update checkpoint warning to target PyTorch 2.9 
 (#160643)

Fixes #160534

Updates the warning in torch.utils.checkpoint to state that starting in PyTorch 2.9, calling checkpoint without explicitly passing use_reentrant will raise an exception. Follows the guidance from the issue discussion.

Subject: [PATCH 0407/1424] [triton_heuristics] Optimize the triton launcher in
 pt2 (#160000)

Summary:

(Original author: Xu Zhao. Commandeered by David to land this since it is relatively urgent)

We observed ~10us PT2-Triton launch overhead regression after pin update.

Before Triton pin-update:
 {F1980557238}

After Triton pin-update:
 {F1980557240}

The root cause is because https://github.com/pytorch/pytorch/pull/145051 adds `_get_args_with_constexprs` to the cubin launcher caller function, which is on the critical path.

The motivation for `_get_args_with_constexprs` was that between triton 3.2 and triton 3.3, the convention for calling Triton kernels (at the level that non-static-cuda-launcher inductor integrates) changed. Previously, the callable did not take constexpr arguments as parameters; after 3.3, it does. With pointwise/reduction kernels, we don't know the constexpr values until after autotuning occurs; so `_get_args_with_constexprs` would inject constexprs into the arguments list before calling the Triton kernel. The fix (in this PR) is to instead inject the constexpr args into the launcher string - this avoids the cost of sorting/reordering arguments which previously occurred upon execution of each kernel.

Note that the static_cuda_launcher.py does not require constants to be passed to the cubin launcher (https://github.com/pytorch/pytorch/blob/e96c7c4bb0f6aeae2ab3b6f040f7d67edbec199a/torch/_inductor/runtime/static_cuda_launcher.py#L220), there is no need to pass in constexprs to the generated launcher code.

The new launcher code needs to work on three cases:
- StaticallyLaunchedCudaKernel
- triton.compile.CompiledKernel
- AOTInductor

+# AOTInductor Debugging Guide
+
+If you encounter CUDA illegal memory access (IMA) errors while using [AOT Inductor](./torch.compiler_aot_inductor.md), this guide provides a systematic approach to debug such errors. AOT Inductor is part of the PT2 stack, similar to torch.compile, but it produces a compilation artifact that can work in a C++ environment. CUDA illegal memory errors can happen non-deterministically and even appear transient at times.
+
+On a high-level, there are three main steps in debugging CUDA IMA errors:
+
+- **Sanity checks**: Use basic debugging flags to catch common issues before diving deeper.
+- **Pinpoint the CUDA IMA**: Make the error deterministic and identify the problematic kernel.
+- **Identify problematic kernels**: Use intermediate value debugging to inspect kernel inputs and outputs.
+
+## Step 1: Sanity Checks
+
+Before diving deep into reliably reproducing the error, try out some existing debugging flags:
+
+```bash
+AOTI_RUNTIME_CHECK_INPUTS=1
+TORCHINDUCTOR_NAN_ASSERTS=1
+```
+
+These flags take effect at compilation time (more precisely, at codegen time):
+
+- `AOTI_RUNTIME_CHECK_INPUTS=1` checks if the inputs satisfy the same set of guards used during compilation. See {ref}`torch.compiler_troubleshooting` for more details.
+- `TORCHINDUCTOR_NAN_ASSERTS=1` adds codegen before and after each Inductor's kernel to check for NaN.
+
+## Step 2: Pinpoint the CUDA IMA
+
+One hard part is CUDA IMA errors can be non-deterministic. They can happen at different locations, and sometimes not happen at all (though that just means the numerics are silently incorrect). With the following two flags, we can trigger the error deterministically:
+
+```bash
+PYTORCH_NO_CUDA_MEMORY_CACHING=1
+CUDA_LAUNCH_BLOCKING=1
+```
+
+These flags take effect at runtime:
+
+- `PYTORCH_NO_CUDA_MEMORY_CACHING=1` disables PyTorch's Caching Allocator, which allocates a bigger buffer than needed immediately to reduce the number of buffer allocations. This is usually the reason why CUDA illegal memory access errors are non-deterministic.
+![How PyTorch's caching allocator can mask CUDA illegal memory access errors](./_static/img/aoti_debugging_guide/cuda_ima_cca.png)
+*Figure: How PyTorch's caching allocator can mask CUDA illegal memory access errors*
+
+- `CUDA_LAUNCH_BLOCKING=1` forces the kernels to launch one at a time. Without this, we would get the famous "CUDA kernel errors might be asynchronously reported at some other API call" warning since kernels are launched asynchronously.
+
+## Step 3: Identify Problematic Kernels with Intermediate Value Debugger
+
+The AOTI Intermediate Value Debugger can help pinpoint the problematic kernel and get information about the inputs and outputs of said kernel.
+
+First, use:
+
+```bash
+AOT_INDUCTOR_DEBUG_INTERMEDIATE_VALUE_PRINTER=3
+```
+
+This flag takes effect at compilation time and prints the kernels one by one at runtime. Together with the previous flags, this would let us know which kernel was launched right before the error happened.
+
+However, it is important to note that just because the error happened in that kernel, it doesn't mean that kernel is problematic. For example, it can happen that an earlier kernel is problematic and produces some wrong outputs. So the natural next step is to inspect the inputs to the problematic kernel:
+
+```bash
+AOT_INDUCTOR_FILTERED_KERNELS_TO_PRINT="triton_poi_fused_add_ge_logical_and_logical_or_lt_231,_add_position_embeddings_kernel_5" AOT_INDUCTOR_DEBUG_INTERMEDIATE_VALUE_PRINTER=2
+```
+
+The filtered kernels to print environment variable has the names of the kernels you want to inspect. If the inputs to the kernel are not as expected, you then inspect the kernel that produces the bad input.
+
+## Additional Debugging Tools
+
+### Logging and Tracing
+
+- **tlparse / TORCH_TRACE**: Provides complete output codes for inspection and records the set of guards used. See {ref}`tlparse / TORCH_TRACE <tlparse-torch-trace>` for more details.
+- **TORCH_LOGS**: Use `TORCH_LOGS="+inductor,output_code"` to see more PT2 internal logs. See {ref}`TORCH_LOGS <torch-logs>` for more details.
+- **TORCH_SHOW_CPP_STACKTRACES**: Set `TORCH_SHOW_CPP_STACKTRACES=1` to potentially see more stack traces.
+
+### Common Sources of Issues
+
+- [**Dynamic shapes**](./torch.compiler_dynamic_shapes.md): Historically a source of many IMAs. Pay special attention when debugging dynamic shape scenarios.
+- **Custom ops**: Especially when implemented in C++ and used with dynamic shapes. There is a need to Symint'ify the meta function.

Subject: [PATCH 0416/1424] [inductor][triton] Update triton_builtin handling
 after triton # 7239 (#160658)

https://github.com/triton-lang/triton/pull/7239 will search for a _semantic kwarg in the signature of the function before passing in this kwarg. To fix this in Inductor:

1. explicitly take a _semantic kwarg
2. remove the functools.wraps around the wrapper function, which was causing inspect.signature to return the signature of the wrapped function (instead of the signature of the wrapper, which does contain the _semantic arg)

Subject: [PATCH 0419/1424] [Inductor] [Triton] Apply feedback to Enable padded
 stride support (#160614)

Summary:
Issue I noticed while fixing tests for TMA store. This triton.language.make_tensor_descriptor call hardcodes the shape information as the stride, which is not necessarily correct.

In particular, its legal to have a stride bigger than the shape (e.g. padded to a size). A good example of the usage of this would be to allocate a tensor to always be a multiple of 16 and just pad the result so TMA is legal.

This is redo of https://github.com/pytorch/pytorch/pull/160493 because I broke this accidentally trying to land internally first instead of merging through Github directly.

Test Plan:
Tested with `buck2 run mode/opt-split-dwarf mode/inplace -c fbcode.nvcc_arch=h100 caffe2/test/inductor:max_autotune 2>&1 | tee ~/test_logs.log` and confirmed all max autotune tests passed.

Rollback Plan:

Subject: [PATCH 0429/1424] [NVIDIA] Refactor Family Blackwell Support codegen
 (#156176)

With the legacy driver (nvgpu) used for CUDA 12.9, Thor was operating with SM 10.1.
This changes to SM 11.0 when the newer driver model (OpenRM), which is intended for CUDA 13.0, is introduced.
Thor 10.1 --> 11.0
Spark 12.1

Subject: [PATCH 0434/1424] Separate provenance tracking to different levels
 (#160383)

Summary: as title. We've got request from various parties who are interested in turning on the provenance tracking by default. In this PR, we prepare to turn on part of the provenance tracking that doesn't have too much overhead by default.

- Change `provenance_tracking` config to `provenance_tracking_level`
- turn on the following provenance tracking by default when `basic_provenance_tracking`=True
    - `set_kernel_post_grad_provenance_tracing` for kernels, this add mapping between triton kernels and post_grad nodes
    - `dump_inductor_provenance_info` if we're dumping tlparse log
    - `get_graph_provenance_json` and dump `reate_mapping_pre_post_grad_nodes`. This creates mapping between pre_grad and post_grad nodes. Since we're not turning on the provenance tracking in GraphTransformObserver by default, the mapping here maybe incomplete/limited.
    - add stack trace from post grad nodes to inductor IR nodes
    - add exception swallowing for all functions above

Subject: [PATCH 0444/1424] Revert "[inductor] dont reuse buffers if it affects
 peak (#145883) (#159530)"

This reverts commit 3be70dc30e893b552fc0f23ca06cd8f7949b6d08.

Reverted https://github.com/pytorch/pytorch/pull/159530 on behalf of https://github.com/clee2000 due to newly added test fail internally D80316528, probably just a targets change, but also imo the tests should probably go into a testcase class from common or inductor utils.  While I'm pretty sure CI can run the globally defined ones, theres some CI related functionality that on the testcase class that CI benefits from ([comment](https://github.com/pytorch/pytorch/pull/159530#issuecomment-3191947506))

Subject: [PATCH 0447/1424] [ez] Make NUMA signpost parameters JSON
 serializable (#160710)

# Context
Broader context in #160163.

In order for the _utils_internal version of signpost_event to do proper logging, its parameters argument needs to be json serializable.

# This PR
Convert `NumaOptions` to serializable form before inputting to `signpost_event`.

# Test Plan
## Automated
Added tests `$ pytest test/test_numa_binding.py`.

## Manual
See [D80317206](https://www.internalfb.com/diff/D80317206).

Subject: [PATCH 0448/1424] Add logging for when inbuilt_inline_nn_modules will
 help with ID_MATCH guard triggered recompiles (#160592)

We add a logging around when an ID_MATCH guard is added at a place where inbuilt_inline_nn_modules would inline it. This is done with the aim of tagging recompiles that could be avoided by setting inbuilt_inline_nn_modules flag.
It will help us log and track the flag's adoption and potentially quantify saving in the the number of recompiles.

Subject: [PATCH 0452/1424] [scan] support gen_schema for scan (#158864)

We don't want to allow scan's combine_fn to mutate its inputs. The semantic of the mutation can be confusing. For example:
```python
def combine_fn(init, x):
```
If combine_fn mutates init, only first iteration mutates init, the rest of the iterations mutates the previous carry, which is an intermediate result. This is kind of a weird semantic because the only observable mutation is for init, which can be done outside of the combine_fn.

If combine_fn mutates x, where x is a slice of scanned inputs (i.e. xs), this pattern is more meaningful but we've not seen any use case yet.

Subject: [PATCH 0453/1424] [associative_scan] support gen_schema for
 associative_scan (#158883)

In-place mutation may create inter-loop dependency that breaks the parallelism we have for associative_scan so we ban input mutations.

Subject: [PATCH 0454/1424] raise exception in case of errors in memory
 reordering (#160455)

This PR introduce two checks in the memory reordering pass to catch graph issues before performing the reordering task. For situation not covered by these checks, the reordering pass might fail and an exception will be thrown in this case.

This addresses issue -- https://github.com/pytorch/pytorch/issues/159568

Subject: [PATCH 0456/1424] port 2 distributed pipeline test files for Intel
 GPU (#159140)

it's another pr to port distributed pipeline test for Intel GPU, while the other pr is https://github.com/pytorch/pytorch/pull/159033.
In this pr, we port two test files for Intel GPU
We could enable Intel GPU with following methods and try the best to keep the original code styles:

1. instantiate_device_type_tests()
2. skip the case at xpu due to accuracy gap introduced by oneDNN non-deterministic

Subject: [PATCH 0457/1424] [inductor] Fix propagating 
 torch.utils._sympy.functions.Identity in IndexPropagation (#155504)

Fixes https://github.com/pytorch/pytorch/issues/160535

Index may contain ` torch.utils._sympy.functions.Identity`. When we call `SymPyOps.index_expr`, if the value is a sympy.Expr with Identity, `TypedExpr(value, dtype)` will fail. So when we unwrap arguments, we expand the sympy expression to unwrap Identity.

Test Plan:
buck run @mode/dev-nosan //caffe2/test/inductor:test_aot_inductor -- -r test_sym_expr_indexing

Rollback Plan:

Subject: [PATCH 0463/1424] Change IR node's stack traces to return a set of
 stack traces only (#160701)

Summary: There can be excessive stack trace outputs in TORCH_LOGS="+inductor" when a single line of code corresponds to many post grad nodes, e.g. `self.multihead_attn(x, x, x)`, in that case, we'll see the same stack trace many times in the IR node, spamming the output log. So we change to return a set of stack traces.

Test Plan:
CI

Rollback Plan:

Subject: [PATCH 0466/1424] [AOTInductor] ABI-Compatibility for RecordFunction.
 (#159842)

Summary:
Previous our implementation for RecordFunction injects Aten into
codegen, which is breaking the ABI contract for AOTInductor.

C10::IValue is aded to call the full record function. The extension of
more profiling info will come in later PRs.

Test Plan:
Included in commit.

Subject: [PATCH 0467/1424] [cuDNN][SDPA] Introduce
 `TORCH_CUDNN_SDPA_AVOID_RECOMPILE=1` (#155958)

Opt-in for now, but basically uses the variable-sequence length/ragged path for the common case of BSHD layout to avoid recompiling for different sequence lengths.

Built on top of #149282

Tested using a primitive fuzzer, seems at least as stable as default path (with recompilation) on B200 (50000+ cases tested without any failures)

Pull Request resolved: https://github.com/pytorch/pytorch/pull/155958

Subject: [PATCH 0472/1424] [BE] Update nvshem dependency to 3.3.20 (#160458)

Which is manylinux2_28 compatible, even on aarch64 platform

archive contents and URL pattern changed quite drastically between 3.3.9 and 3.3.20, but hopefully it still works.
Package `libnvshmem_host.so.3` into gigantic aarch64+CUDA wheel
Should fix https://github.com/pytorch/pytorch/issues/160425

Subject: [PATCH 0476/1424] [BE] Update nvshem dependency to 3.3.20 (#160458)

Which is manylinux2_28 compatible, even on aarch64 platform

archive contents and URL pattern changed quite drastically between 3.3.9 and 3.3.20, but hopefully it still works.
Package `libnvshmem_host.so.3` into gigantic aarch64+CUDA wheel
Should fix https://github.com/pytorch/pytorch/issues/160425
Pull Request resolved: https://github.com/pytorch/pytorch/pull/160458
Approved by: https://github.com/Skylion007, https://github.com/kwen2501, https://github.com/nWEIdia, https://github.com/atalman, https://github.com/tinglvv

Subject: [PATCH 0477/1424] [ROCm][Windows] Add hipcc compatibility flags to
 cpp_extension.py. (#159790)

This is a similar change to https://github.com/pytorch/pytorch/pull/153986, this time adding flags to the hipcc command under `cpp_extension.py`.

The `-Wno-ignored-attributes` flag in particular avoids about 200MB of warning spam when building torchvision, like these:
```

      |                               ^~~~~~~~~
```

The `-fms-extensions` flag just seems beneficial to include: https://clang.llvm.org/docs/MSVCCompatibility.html.

See also this downstream issue where these changes were tested: https://github.com/ROCm/TheRock/issues/910.

Subject: [PATCH 0484/1424] [ONNX] Default to dynamo export (#159646)

Set dynamo=True and enable fallback.

1. Implemented the compatible behavior where BytesIO objects as `f` is accepted
2. Update tests to explicitly set dynamo=False

Subject: [PATCH 0485/1424] Fix mypy errors: PyTreeSpec inheritance (#160652)

Fixes #160650.

I added type ignore comment to `LeafSpec` class inheritance in `torch/utils/_cxx_pytree.py` to handle `PyTreeSpec` being marked as final in optree's type stubs.

Subject: [PATCH 0486/1424] Update transformers version automatically with
 Dependabot (#160635)

My proposal here is to use GitHub Dependabot to make sure that `transformers` version used in CI are always up-to-date.  To achieve this, this PR does 2 things:

1. Pin `transformers` version across all CI jobs to only one place at `.ci/docker/ci_commit_pins/huggingface.txt`.  This file is now a regular pip requirements instead of a pinned commit text.  There isn't any need to pin `transformers` to a specific commit and the file already refers to a stable version `v4.54.0`
2. Create `.github/dependabot.yml` to config the bot to update `transformers` automatically when there is a new version.  Those labels will ensure that the right reviewers from torch.compile and Dev Infra are notified.  I'm not sure how to test this out in PR, but it feels ok to land and test this in main.  If this works, we should see a PR to update `v4.54.0` to the current latest `v4.55.0`

Subject: [PATCH 0487/1424] Remove guard_size_oblivious from default contiguity
 python check, and add aten.sym_is_contiguous. (#159197)

This might cause some new DDEs on call sites that do not use is_contiguous_or_false() or sym_is_contiguous()
but want to find those call sites to handle this properly by calling  is_contiguous_or_false() and not is_contiguous() explitly when appropriate.
I had to fix one issue after removing the implicit size oblivious reasoning. here is context

we defined in this https://github.com/pytorch/pytorch/pull/157472 sym_is_contiguous to be the function computing contiguity for dynamic shapes in c++. It returns a symbolic expression that represents contiguity and guaranteed not to throw a DDE.

when people call is_contiguous we do sym_is_contiguous().guard_bool()
when people call is_contiguous_or_false we do sym_is_contiguous().guard_or_false()

one issue not handled well was this path
```
c10::SymBool TensorImpl::sym_is_contiguous_custom(
    at::MemoryFormat memory_format) const {
  if (C10_UNLIKELY(matches_python_custom(SizesStridesPolicy::CustomStrides))) {
    return pyobj_slot_.load_pyobj_interpreter()->is_contiguous(
        this, memory_format);
  }

  return sym_is_contiguous_default(memory_format);
}
```
namely if we call sym_is_contiguous_custom but we have matches_python_custom(SizesStridesPolicy::CustomStrides) return true , then we used to call is_contiguous(this, memory_format);

This used to go through the load_pyobj_interpreter and end up calling the python is_contiguous call which used implicit size oblivious reasoning.
once we removed that implicit size oblivious reasoning, the right thing we want is to call
return pyobj_slot_.load_pyobj_interpreter()->sym_is_contiguous(this, memory_format);
otherwise we would get DDE even if the caller is doing sym_is_contiguous.

so I had to define it for pyinterpreter, and then I had to override it for nested tensors.

Subject: [PATCH 0493/1424] [collections.abc] Ensure that binop calls works
 with UserDefinedObjects (#159865)

Changes:
(1) Replace UserDefinedSetVariable by UserDefinedObjectVariable in all binop calls

Test plan:
(1) The three tests from CPython `test_collections.py` ensures that Dynamo can trace through a dunder method (e.g. __add__, __ixor__, etc) defined in a user defined class

Subject: [PATCH 0494/1424] Revert "[inductor] TLParse tensor metadata logging
 + test (#160132)"

This reverts commit 2603e40be5fa4a66301e6654e34a82a67f2e4913.

Reverted https://github.com/pytorch/pytorch/pull/160132 on behalf of https://github.com/clee2000 due to broke lint [GH job link](https://github.com/pytorch/pytorch/actions/runs/17010600949/job/48226137423) [HUD commit link](https://hud.pytorch.org/pytorch/pytorch/commit/2603e40be5fa4a66301e6654e34a82a67f2e4913).  landrace with another PR that changed some had_cuda related things ([comment](https://github.com/pytorch/pytorch/pull/160132#issuecomment-3193969792))

Subject: [PATCH 0495/1424] [BE] [Inductor] Re-Land Support TMA before strict
 3.4 cutoff (#160747)

Summary: Inductor's 3.4 Triton release is the most common used variant of Triton, but if someone is working with an alternative version of Triton this may not match. This moves the version check from 3.4 Triton to any variant that has support for the TMA APIs.

Test Plan:
Testing the previously failing test `inductor/test_torchinductor_strided_blocks.py::TritonTensorDescriptorTestCUDA::test_welford_non_block_pointer_cuda`

Rollback Plan:

Subject: [PATCH 0501/1424] [easy] [Precompile] Refactor guards, improve typing
 (#160530)

Purely a refactor, improve typing and get rid of some type errors. Make certain fields as nonnull, since in general it's not empty.

The goal of this stack of PRs is to move the save/load logic of guard serialization into separate, flat phases, instead of being embedded in guard creation. This way, we can put a try/catch around it and fail safely if certain guards are not serializable.

Subject: [PATCH 0504/1424] Revert "Use numpy 1.26.2 for Python 3.9 and 3.10
 (#160836)"

This reverts commit 7a68d02292fd7a430b55c5bce3268a33c7ec5055.

Reverted https://github.com/pytorch/pytorch/pull/160836 on behalf of https://github.com/clee2000 due to broke some inductor jobs? Maybe just update the expected values? Not sure what the policy is for something like this [GH job link](https://github.com/pytorch/pytorch/actions/runs/17024529273/job/48262123844) [HUD commit link](https://hud.pytorch.org/pytorch/pytorch/commit/7a68d02292fd7a430b55c5bce3268a33c7ec5055) ([comment](https://github.com/pytorch/pytorch/pull/160836#issuecomment-3194953213))

+/**
+ * A helper class for matching a subgraph pattern within a larger graph.
+ * It attempts to match a given `pattern` graph inside a target `graph`,
+ * starting from a single "root" output node in the pattern graph. The
+ * matching process works backward through the graph, comparing each node
+ * in the pattern to corresponding nodes in the candidate graph.
+ *
+ * Note: This implementation currently only supports deterministic matching
+ * for patterns with one output node. It also only matches nodes connecting to
+ * output nodes
+ *
+ * Constraints for Patterns with Multiple Output Nodes:
+ * To avoid an exponential increase in the search space, this implementation
+ * starts searching from the first output node as an anchor as an heuristic. It
+ * assumes that all other output nodes in the pattern are interconnected through
+ * the graph from this anchor node, allowing the matcher to traverse from the
+ * anchor to other outputs.
+ *
+ * Important: The order of output nodes in the pattern matters. For example:
+ *
+ *   graph(%x):
+ *       %a = a.aaa(input=%x)
+ *       %b = b.bbb(input=%a)
+ *       return (%a, %b)
+ *
+ * If the search starts from %a, it will not explore the portion of the graph
+ * connected to %b. However, if the order is switched:
+ *
+ *   graph(%x):
+ *       %a = a.aaa(input=%x)
+ *       %b = b.bbb(input=%a)
+ *       return (%b, %a)
+ *
+ * The search will start from %b and successfully explore both %b and %a.

+# CuteDSL Template System
+
+## Quick Start
+
+Writing a CuteDSL template:
+
+```python
+from torch._inductor.codegen.cutedsl import CuteDSLTemplate
+
+template_source = """
+@cute.kernel
+def {{kernel_name}}_kernel(A, B, C):
+    # Your CUTLASS kernel logic here
+    pass
+
+{{def_kernel("A", "B", "C")}}
+    # Call the kernel
+    {{kernel_name}}_kernel(A, B, C)
+    return C
+"""
+
+my_template = CuteDSLTemplate(
+    name="my_gemm",
+    source=template_source,
+)
+```
+
+## Architecture
+
+- **[CuteDSLTemplate](cutedsl_template.py#L39)**: Template definition and registration. Generates ChoiceCallers for autotuning.
+- **[CuteDSLTemplateKernel](cutedsl_kernel.py#L61)**: Handles code generation, provides template hooks (`def_kernel`), manages args.
+- **[CuteDSLScheduling](cutedsl_scheduling.py#L28)**: Integrates with Inductor's scheduler, handles kernel compilation via [`async_compile.cutedsl()`](../../async_compile.py#L756).
+- **[CuteDSLTemplateBuffer](../../ir.py)**: IR node representing a CuteDSL template operation in the graph.
+
+### Compilation Process
+
+CuteDSL requires source files for compilation (cannot compile from strings directly). The process:
+
+1. **[CuteDSLScheduling](cutedsl_scheduling.py#L59)** generates the kernel code string and calls [`async_compile.cutedsl()`](../../async_compile.py#L756)
+2. **[async_compile.cutedsl()](../../async_compile.py#L756)** uses [`PyCodeCache.write()`](../../codecache.py) to write source to a temporary `.py` file
+3. **[PyCodeCache](../../codecache.py)** loads the module from disk, enabling CUTLASS compilation
+4. The compiled kernel is wrapped in **[CuteDSLKernelWrapper](cutedsl_kernel.py#L22)** to provide a `.run()` interface
+5. The generated Python file is cached via PyCodeCache, but CUTLASS compilation runs every time (no kernel-level caching yet)
+
+**Debug tip**: Use `TORCH_LOGS="kernel_code"` to see the generated kernel source and file path during compilation.
+
+## Writing Templates
+
+Templates use Jinja2 syntax with these available hooks:
+
+- `{{kernel_name}}` - Unique kernel identifier
+- `{{def_kernel(args...)}}` - Generates kernel function signature and argument handling
+- `{{input_nodes}}` - List of input buffers
+- `{{output_node}}` - Output buffer
+- `{{gen_defines()}}` - Generates autotunable parameter definitions with proper CuteDSL typing
+
+## Autotunable Parameters
+
+CuteDSL templates support autotunable parameters similar to Triton's `tl.constexpr` system:
+
+```python
+template_source = r"""
+{{gen_defines()}}
+
+@cute.kernel
+def {{kernel_name}}_kernel(gA: cute.Tensor, gB: cute.Tensor, gC: cute.Tensor):
+    threads_per_block = THREADS_PER_BLOCK  # Uses autotuned value
+    block_size = BLOCK_SIZE
+    # ... kernel implementation
+"""
+
+# Pass parameters when generating template choices
+template.maybe_append_choice(
+    choices,
+    input_nodes=[a, b],
+    layout=layout,
+    THREADS_PER_BLOCK=256,    # cutlass.Constexpr = 256
+    BLOCK_SIZE=128,           # cutlass.Constexpr = 128
+    SCALE_FACTOR=1.5,         # cutlass.Constexpr = 1.5
+)
+```
+
+Templates must:
+1. Define a `@cute.kernel` decorated function
+2. Use `{{def_kernel()}}` to create the entry point
+3. Return the output tensor
+4. Use `{{gen_defines()}}` for autotunable parameters
+
+See [test_cutedsl_template.py](../../../../test/inductor/test_cutedsl_template.py) for complete examples.
+
+## Current Limitations / TODOs
+
+- **No fusion support**: `can_fuse_vertical` and `can_fuse_horizontal` return False
+- **Subgraph management**: Bodies and masks not fully implemented
+- **File-based compilation**: Requires writing to disk (uses PyCodeCache)
+- **Missing epilogue/prologue**: No support for fused operations yet
+- **Fixed kernel suffix**: Uses hardcoded "_main" suffix
+- **No CUTLASS kernel caching**: Only PyCodeCache works; CUTLASS compilation runs every time (major perf issue)
+
+
+Note: Requires CUTLASS Python package (`pip install nvidia-cutlass`)

Subject: [PATCH 0510/1424] [Inductor] modify convert_to_reinterpret_view
 (#158914)

**Summary:**
Fix https://github.com/pytorch/pytorch/issues/159121, Modify the rules for freezing the layout of `x.unwrap_view()` in `convert_to_reinterpret_view`: relax the condition of `isinstance(x_unwrap_view, (ReinterpretView, Buffer))` to `isinstance(x_unwrap_view, (ReinterpretView, Buffer, MutableBox))`. Prefer channels last format according to how the format of `x_unwrap_view_fx_node` is set from eager.

**Example:**
```
import torch
import torch.nn as nn

class M(nn.Module):
    def __init__(self):
        super(M, self).__init__()
        self.relu = torch.nn.ReLU()

    def forward(self, x):
        n, c, h, w = x.shape
        return self.relu(x).permute(0, 2, 3, 1).reshape(
            n, h * w, c
        )

model = M().eval()
x = torch.randn(2, 32, 4, 4).to(memory_format=torch.channels_last)

compiled_model = torch.compile(model)

with torch.no_grad():
    compiled_model(x)
```

Subject: [PATCH 0511/1424] [inductor] pack linear for FP32 dynamic mode
 (#157542)

Summary:
Currently, Linear in FP32 dynamic mode(batch_size has free symbols) does not support weight prepacking since MKL Linear does not support dynamic mode. This PR uses oneDNN Linear to support Linear weight prepacking in FP32 dynamic mode.
I tested the Inductor benchmark in FP32 dynamic mode on CPU using this PR, and saw ~8% improvement in timm_models geomean speedup, ~2%  improvement in torchbench geomean speedup, and no change in huggingface. There are about 18 models with different degrees of performance improvement, among which BERT_pytorch, soft_actor_critic, BlenderbotForCausalLM, ElectraForCausalLM, crossvit_9_240, mobilevit_s, twins_pcpvt_base have more than 20% performance improvement.

Subject: [PATCH 0514/1424] [ROCm][inductor][dashboard] Add
 GPT2ForSequenceClassification to use_larger_multiplier_for_smaller_tensor
 list (#160001)

GPT2ForSequenceClassification Hugging Face (HF) model fails on ROCm for bfloat16. The failure is numerically small.  This PRs adds this model to an exception list for small tensors. The exception list already includes two models. This increases the multiplier factor to 10.0 instead of 3 (default) for this model used in `torch/_dynamo/utils.py`.

In the PR comment below, I include a short analysis of the numerics.

Subject: [PATCH 0517/1424] [export] Fix custom ops in subgraphs (#160004)

Fixes https://github.com/pytorch/pytorch/issues/159995

Currently there are two problems with extern kernels in subgraphs:
1. They don't get serialized to the extern kernel json file because we only look at the toplevel graph.
2. Since the scope of each extern_kernel list is within its own subgraph, the indices referencing the operator is messed up because each subgraph will start counting from 0.

So, this PR moves the extern_kernels list to a global view (under virtualized) so that we can count the extern kernels across subgraphs and the toplevel graph.

 Support (#151360)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- This pull request introduces support for the [OCP Micro-scaling (MX) format](https://www.opencompute.org/documents/ocp-microscaling-formats-mx-v1-0-spec-final-pdf), with a focus on compatibility with AMD **ROCm 7.0** and the **gfx950** architecture.

  This PR also establishes the foundation for enabling MX-FPX features in [TorchAO](https://github.com/pytorch/ao/issues/2229) on the AMD platform.

- Validation (**ROCm 7.0** + **gfx950** required):

  `111 relevant tests passing.`

  > PYTORCH_TEST_WITH_ROCM=1 python test/test_matmul_cuda.py -k test_blockwise -v

  Co-author: @jagadish-amd —  Thank you for the efforts leading validation on gfx950 with ROCm 7.0.

-----------------------------------

This pull request introduces support for new scalar types and scaling methods, particularly for ROCm 7.0 and gfx950, and refines testing for these features. Key changes include adding constraints for matrix dimensions, enabling block-wise scaling, and updating tests to accommodate new data types.

### Support for new scalar types and scaling methods:
* [`aten/src/ATen/cuda/CUDABlas.cpp`](diffhunk://#diff-74fcb26047c1df4024105d36ce22a36b77cf8cc93c28631d743e639b3d6066aeR1876-R1885): Added constraints for matrix dimensions when using `Float8_e8m0fnu` with block-wise scaling, ensuring dimensions are multiples of 32. Updated compatibility checks to support ROCm 7.0 for `Float8_e8m0fnu` and `Float8_e4m3fn`. [[1]](diffhunk://#diff-74fcb26047c1df4024105d36ce22a36b77cf8cc93c28631d743e639b3d6066aeR1876-R1885) [[2]](diffhunk://#diff-74fcb26047c1df4024105d36ce22a36b77cf8cc93c28631d743e639b3d6066aeL1913-R1934)

* [`aten/src/ATen/native/cuda/Blas.cpp`](diffhunk://#diff-e8a569efee1e650172f120a0fdcda024fe3e4703a4ee3336425c8f685af6b3abR1276-R1290): Introduced block-wise scaling for `Float8_e8m0fnu`, with checks for ROCm 7.0 and GPU architecture `gfx950`. Added validation for supported scalar types and matrix dimensions. [[1]](diffhunk://#diff-e8a569efee1e650172f120a0fdcda024fe3e4703a4ee3336425c8f685af6b3abR1276-R1290) [[2]](diffhunk://#diff-e8a569efee1e650172f120a0fdcda024fe3e4703a4ee3336425c8f685af6b3abR1349-R1364)

### Updates to scalar type mappings:
* [`aten/src/ATen/cuda/CUDADataType.h`](diffhunk://#diff-9188bb13b1a49f459141f5f9b875593d1c5ce2beb5ad711fdbaf5bc7089ec015L93-R93): Extended scalar type mappings to support `Float4_e2m1fn_x2` for ROCm 7.0.

* [`aten/src/ATen/cuda/tunable/GemmHipblaslt.h`](diffhunk://#diff-bfa1a3b5d4bef1892bf50338775f3b0fd8cd31fc1868148f3968b98aefb68e3fR88-R96): Added a constexpr mapping for `Float4_e2m1fn_x2` based on ROCm version.

### Enhancements to testing(@jagadish-amd):
* [`test/test_matmul_cuda.py`](diffhunk://#diff-3f31c52b48cfddf8f4617d809f7695b2e4a1c78656f8c4b5143a4b45d01fcf23R765-R766): Updated tests to include new scalar types (`Float4_e2m1fn_x2`) and recipes (`mxfp4`). Added logic to handle different scaling recipes and validate compatibility with ROCm and CUDA versions. [[1]](diffhunk://#diff-3f31c52b48cfddf8f4617d809f7695b2e4a1c78656f8c4b5143a4b45d01fcf23R765-R766) [[2]](diffhunk://#diff-3f31c52b48cfddf8f4617d809f7695b2e4a1c78656f8c4b5143a4b45d01fcf23L1331-R1356) F592e669L1353R1472)

These changes improve compatibility with newer hardware and software versions, enhance functionality for matrix operations, and ensure robust testing for the added features.

Subject: [PATCH 0522/1424] Replace guard_serialization_mode with save_guards,
 remove load cases (#160531)

This PR replaces "guard_serialization_mode" into `save_guards`. All cases where we care about whether or not we're *loading* guards can be inferred automatically from the existing inputs.

The only case that's special here is whether or not to check guards. We don't want to check guards on guard load in CheckFnManager, because these guards have already been checked on save. Therefore, we put the setting in OutputGraphGuardsState, so that when we save, we bypass the guards check.

Because of this change, it is *technically* possible to do a load and a save in the *same* CheckFunctionManager.__init__() by passing all the necessary parts, and also passing `save_guards=True`. This should just work out of the box, but so far no callsites need it, so not super important.

Next up, we'll work on removing save_guards from GuardBuilder, and putting it into its own phase.

Subject: [PATCH 0526/1424] Add `is_cpu` method to stable tensor type (#160212)

Porting torchaudio to use the stable api requires the `is_cuda` and `dtype` functions. It would be more convenient if these were methods of the stable tensor class rather than utilities one needed to call from the C api. This PR adds them as methods, mirroring how `is_cuda` and `get_device` are already defined.

Subject: [PATCH 0527/1424] Recheck Autotune cache on Precompile serialization
 to prune compilation results (#158656)

This PR rechecks the autotune cache on Precompile.serialize(), allowing us to ahead of time save autotune results for statically compiled triton kernels, so that warm start does not need to check the autotune cache.

It has a few extra changes to make this work:

### Storing source code in TritonBundler
- We now store the source_code for statically compiled triton kernels instead of the hash of the source code in TritonBundler, so that we can easily access their source code when rechecking the autotune cache on PrecompileContext.serialize. To make sure that this is not a huge space concern, I ran the entire hugging face benchmark on training. The total space of `/tmp/torchinductor_jjwu/fxgraph` before my change was 1185004 KB (1.18 GB). After my change, this increased to 1207312 KB (1.2 GB), for an increased storage cost of ~1.8%, which seems safe.

- We now return early from recheck_autotune_cache if the number of triton kernels being compiled is 1, since there's no reason to check the cache at all in those cases.

Subject: [PATCH 0530/1424] [aoti-fx] Initial AOTInductor FX (#160765)

Using the existing WrapperFxCodegen backend, this PR prototypes an AOT version of it which will directly return a graph module.

How to use:
```python
exported_gm = torch.export.export(model, inp, dynamic_shapes=dynamic_shapes).module()
compiled_gm = torch._inductor.aot_compile(
    exported_gm, inp, options={"fx_wrapper": True, "compile_threads": 1}
)
assert torch.allclose(model(*inp), compiled_gm(*inp))
```

The motivation behind this is that backends like ExecuTorch/MTIA would like to use inductor's optimization technologies, but might have their own graph lowering pipelines so they might not want to use AOTI (which generates an so).

Subject: [PATCH 0536/1424] [dynamo] Fix crash and silent incorrectness issues
 in `attention.sdpa_kernel` calls with kwargs (#160684)

This patch fixes 2 issues, illustrated by the test cases added:
1. using `sdpa_kernel(backends=..., set_priority=...)` due to an
   internal assert that forgot to be updated after #147768.
2. forgetting to convert the `set_priority` VariableTracker back to a
   python constant so that its value is properly used by `sdpa_kernel`,
   also from #147768.

I ran into (1) because ComfyUI had a recent update that actually sues
this pattern
https://github.com/comfyanonymous/ComfyUI/blob/644b23ac0b92442b475e44397c62aa8de929d546/comfy/ops.py#L44,
and then noticed (2), and fixed it conveniently.

Subject: [PATCH 0537/1424] [dynamo] Fix graph break on calling functions
 decorated with special context manager (#160703)

As title. This is a follow-up of the previous patch, with the goal of
supporting a new pattern that showed up in ComfyUI:
https://github.com/comfyanonymous/ComfyUI/blob/644b23ac0b92442b475e44397c62aa8de929d546/comfy/ops.py#L44

Effectively, the semantics of calling a function decorated with a
context manager is:

```python
@ctx_manager(args)
def f(x):
    ...

f(x)
# ----->
with ctx_manager(args):
    f.__wrapped__(x)
```

Yes, a fresh context manager instance per invokation, see CPython source code:
https://github.com/python/cpython/blob/3.12/Lib/contextlib.py#L119-L122

So Dynamo already
1. knows how to handle the `with ctx_manager(args)` syntax, and has
   special handling for a few torch native context managers, like
   `sdpa_kernel` in this patch.
2. can trace through a good chunk (at least the ones that matter in this
   case) of contextlib.

This patch just let Dynamo trace a bit more into contextlib, and then
keep the torch-native special cases by moving their handling a bit down
the stack, so that no additional logic is introduced -- it's only
refactored.

This also allows us to get rid of some `_sdpa_kernel_variadic` special
handling, since now we will trace through its code, and it boils down to
`sdpa_kernel` anyways.

Subject: [PATCH 0538/1424] [cpp][inductor] Fix crash on bmm when input is used
 twice. (#160087)

Fixes #156412

For torch.bmm using CPP generated template code, when the input is used as both the first and second weights, the generated code will simplify so it only passes one input instead of 2. However, if the weights are being repacked and saved for more efficient data-loading patterns, then we need to save both inputs instead of just one. This PR fixes this issue.

## Test code:
```python
import torch

@torch.compile(mode="max-autotune")
def my_function(x, y):
    return torch.bmm(x, x)

# Test
x = torch.randn(2, 3, 3)
y = torch.randn(2, 3, 3)
result = my_function(x, y)
```

Subject: [PATCH 0539/1424] For sdists, replace symlink with copy for docs
 requirements (#157811)

Before this change, there was the requirements file `.ci/docker/requirements-docs.txt` which was symlinked as `../.ci/docker/requirements-docs.txt` from `docs/requirements.txt` since #151796.
In this situation, [because `.ci` is excluded from the source tarball](https://github.com/pytorch/pytorch/blob/3173616532ecf0d5c0b78595d6054f1b4bd2bd75/.github/workflows/create_release.yml#L67), we end up with a broken symlink, that additionally is [invalid in a Python source distribution](https://packaging.python.org/en/latest/specifications/source-distribution-format/#unpacking-without-the-data-filter).

The broken symlink can be confirmed in [the rc sources](https://github.com/pytorch/pytorch/actions/runs/15892205745).

~After this change, there is still a single source of truth, which now is `docs/requirements.txt`, symlinked as `../docs/requirements.txt` from `.ci/docker/requirements-docs.txt`, which would also be invalid in a Python source distribution, but is not included in the tarball (see above). Additionally, the docs requirements that were missing from the previous tarball, are now actually included, allowing users to build the documentation again.~

@malfet clarified offline that there is a problem with the docs workflows because they use a cache with a key that includes the hash of the requirements document in the `.ci` folder, which now does no longer change when the requirements change. Hence, a different solution is needed~, though for now the problem remains~.

The solution in this PR is simply to copy the actual document to replace the symlink just prior to creating the source distribution. This way, a single document needs to be maintained, git checkouts remain as they are, and the source distributions contain the before-missing document.

A better solution may be implemented at a later stage with a better build system.

Subject: [PATCH 0540/1424] [BE][CUDA][Distributed] Add
 require_exact_world_size() and a few distributed unit test fixes   (#160803)

1. Add require_exact_world_size()
2. Decorate the test `test_new_subgroups_with_group_param` with this require_exact_world_size(4) as the test would fail with world_size of 8 when testing with 8xB200 runner.
3. Modify `test_new_subgroups_world_size_not_divisible_by_group_size` so that it will not fail due to 4 vs. 8 mismatch. Doing so makes the test pass with both 4-GPU runner and 8-GPU runner.

Separating these changes out from B200 distributed runner PR #159323

Fixes https://github.com/pytorch/pytorch/issues/159987

Subject: [PATCH 0543/1424] harden fabric checks for symmetric memory (#160790)

Now we check only that fabric allocation succeeded, but sometimes we fail during export or import afterwards, with no recourse. Check the full cycle before attempting to allocate memory with the fabric.
TODO: move it to c10/cuda so that it can be used from CUDACachingAllocator too

Subject: [PATCH 0544/1424] [dynamic shapes] unbacked-safe slicing (#157944)

Generates new unbacked symbols for slice output size & storage offset, when appropriate semantics are unclear. Teaches inductor to codegen the slice with flexible semantics.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/157944
Approved by: https://github.com/laithsakka

Subject: [PATCH 0549/1424] Fix duplicated kernel name in kernel stack trace
 tracking (#160905)

Summary: as title. When we have two kernels with the same name, the stack traces should be appended, not overwritten.

Test Plan:
```
 buck run mode/opt fbcode//caffe2/test/inductor:provenance_tracing

Subject: [PATCH 0553/1424] [dynamo] Refactor tracer logic in convert_frame so
 that it doesn't leak to outer layer. [1/n] (#160814)

We are refactoring dynamo code for convert frame so that we can have modularized pieces sharable between different compiler frontends (e.g. torch.compile, precompile and torch.export).

One incremental step we can take is to refactor out InstructionTranslator as a functional piece providing bytecode tracing.

To separate out this part, we notice currently the tracer object is being passed around in the entire convert frame compile function. This is not very ideal because we want to build a boundary between the tracing and downstream compiler stack. Ideally, we should extract all the relevant information out of the tracer object and return a new data structure that is free of internal states of InstructionTranslator.

Luckily, there aren't many data used from tracer, after tracing is finished. The major one is OutputGraph, other than that, we only need to record two boolean flags for error handling purposes.

The new type we're adding is called DynamoTracerOutput, which contains all the information needed by torch.compile internal after symbolic convert is finished. To simplify the current PR, we leave out the part which reduce OutputGraph into a minimal set, since this can be done in a separate PR.

Subject: [PATCH 0554/1424] [PT2]: Allow None for
 wrapped_fbgemm_linear_fp16_weight (#160802)

Summary: Currently the implementation of [fbgemm_linear_fp16_weight](https://www.internalfb.com/code/fbsource/[ffe8ba561cb6af33fde5b32c27411d6d3f4f2c70]/fbcode/caffe2/aten/src/ATen/native/QuantizedLinear.cpp?lines=477) does not allow None for `bias`, but it's actually a valid case and internally `fbgemm_linear_fp16_weight_fp32_activation` accept None bias as well. For BC reason, we can't directly change the function signature. So wrapping an empty tensor if bias is None to workaround it in Sigmoid.

Test Plan:

Subject: [PATCH 0555/1424] [FSDP][Collectives] skipping reduce_scatter when
 world size is 1 (#160136)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

**Summary:** In its current state, FSDP collectives uses cuda synchronizations and communication ops regardless of what the world size is. However, now that replicate will use FSDP, there will be instances where group size = 1 and these synchronizations and ops will be used needlessly. I have updated fsdp_collectives to skip reduce_scatter in the foreach_reduce API when world_size ‎ = 1. I have created edited a test that uses CommDebugMode to verify that the reduce_scatter has been removed. I also edited an affected test which used 1-way FSDP by verifying and changing its assert statements for CommDebugMode. I have also added a test command.

**Test Cases**
1. pytest test/distributed/_composable/fsdp/test_fully_shard_training.py -k test_train_parity_single_worldsize1
2. pytest test/distributed/_composable/test_composability/test_2d_composability.py -k test_tp_with_fsdp_offloading

Subject: [PATCH 0556/1424] [FSDP] Use post_reduce_stream.record_event() on
 hsdp+cpuoffload (#160481)

Fixes https://github.com/pytorch/pytorch/issues/160291
`post_reduce_stream` is `all_reduce_stream` during HSDP, but CPU-GPU sync is hard coded to `reduce_scatter_stream`
The hard-code could fail unit test on HSDP+CPU offload, add unit test here.

Subject: [PATCH 0558/1424] [while_loop][inductor] fix aliased inputs by
 cloning (#160668)

[fx_graph_cse](https://github.com/pytorch/pytorch/blob/main/torch/_functorch/compile_utils.py#L46) is executed in min_cut partitioner which accidentally creates the aliasing for empty buffers and we could see the following graph node for joint graph with cmd: "pytest test/functorch/test_control_flow.py -k test_scan_multiple_layers_gradient_layers_2_device_cpu"
```python
while_loop = torch.ops.higher_order.while_loop(while_loop_cond_graph_0_0, while_loop_body_graph_0_0, (full_default_4, empty_strided_default, full_default_2, full_default_3, full_default_2, full_default_3, full_default, full_default, rev, rev_1, rev_2, rev_3), (primals_4, primals_5, primals_6, primals_7));
```

Notice the operands sequence **"full_default_2, full_default_3, full_default_2, full_default_3, full_default, full_default"**, which indicates the gradient of different layers now sharing the same buffer, which create silent incorrectness.

Fixes https://github.com/pytorch/pytorch/pull/158168.

Subject: [PATCH 0559/1424] Make Inductor benchmarker more compatible with
 Triton do_bench (#160921)

Common benchmark suites like TritonBench uses `triton.testing.do_bench` for kernel timing measurement which is not always fair for all backends. E.g. it includes torch.compile Dynamo invocation overhead and hence doesn't reflect real-world model use case where Dynamo overhead is usually hidden.

I also opened a PR to use this timing measurement function on TritonBench side: https://github.com/meta-pytorch/tritonbench/pull/333. But regardless of whether that PR can land, I think we should enhance Inductor benchmark_gpu to match do_bench features, to make it easier to people to migrate.

Subject: [PATCH 0560/1424] [ez] Only use default numa bindings if nproc ==
 cuda device count (#160848)

# Context
Another fix to enable broad rollout of #149334.

The implementation assumes that the trainer process with local rank `n` only uses device `cuda:n`. However, there are sometimes jobs with more than one GPU per process, in which case our assumption could be incorrect and actually lead to worse memory locality.

# This PR
As titled.

Subject: [PATCH 0564/1424] [BE][inductor] tl.dot(..., allow_tf32=...) ->
 tl.dot(..., input_precision=...) (#160711)

allow_tf32 is deprecated. Also, this will make it easier to support tf32x3 (i.e. #160359).

Subject: [PATCH 0567/1424] [BE] [Inductor] Re-Land Support TMA before strict
 3.4 cutoff (#160747)

Summary: Inductor's 3.4 Triton release is the most common used variant of Triton, but if someone is working with an alternative version of Triton this may not match. This moves the version check from 3.4 Triton to any variant that has support for the TMA APIs.

Test Plan:
Testing the previously failing test `inductor/test_torchinductor_strided_blocks.py::TritonTensorDescriptorTestCUDA::test_welford_non_block_pointer_cuda`

Rollback Plan:

Subject: [PATCH 0572/1424] Move save guard error throwing to separate phase
 (#160662)

This diff makes it so that the portion saving guards that can throw is completely separated from GuardBuilder, and instead in `serialize_guards`. This lets me add a try catch around it for caching precompile later.

Subject: [PATCH 0573/1424] Update checkpoint warning to target PyTorch 2.9
 (#160725)

Follow-up to #160534. Fixes the docstrings and the warning in checkpoint_sequential, which presumably should have same deprecation notice

Subject: [PATCH 0575/1424] [codemod] Fix unused-local-typedef issue in
 caffe2/aten/src/ATen/native/cuda/CUDALoops.cuh +2 (#160944)

Summary:
LLVM has a warning `-Wunused-local-typedef` which we are enabling to remove unused code. This has the side-effect of making it easier to do refactors should as removing unnecessary includes.

Subject: [PATCH 0578/1424] Port amax to stable ABI (#160214)

To enable porting torchaudio to the stable ABI, we need the `amax` operation to be accessible. This PR ports the op and provides tests that it behaves correctly.

Subject: [PATCH 0579/1424] [dynamic shapes] unbacked-safe slicing (#157944)

Generates new unbacked symbols for slice output size & storage offset, when appropriate semantics are unclear. Teaches inductor to codegen the slice with flexible semantics.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/157944

Subject: [PATCH 0581/1424] Tweak dependabot to run inductor jobs (#160935)

After https://github.com/pytorch/pytorch/pull/160635, I can see dependabot creating the PR to bump `transformers` version at https://github.com/pytorch/pytorch/pull/160807.  This a good start, but there are several tweaks we need:

1. Run inductor tests on the PR including one round of perf benchmark, which is always needed.  So, we need `ciflow/inductor` label and a `pull_request` trigger for the benchmark
2. Per @anijain2305 feedback, we don't need to update patch version.  So, I add a rule to ignore it.  Again, we would need to test this out after this lands.

Subject: [PATCH 0585/1424] [SymmMem] Support rendezvous on slice of a tensor
 (#160825)

When we search for a NVSHMEM allocation backing a tensor, don't limit it to an exact match between `tensor.data_ptr()` and `allocation.base_ptr`. Instead, test whether the former is within an allocation range, i.e. [base_ptr, base_ptr + size).

This PR also squashed in original base PR #160795:
Since (i) `handle = rendezvous(tensor)`, and (ii) we pass `handle->buffer_ptrs` to kernels, `handle` should carry the `data_ptr()` of tensor instead of the base address of a memory allocation (previous case).

Pull Request resolved: https://github.com/pytorch/pytorch/pull/160825
Approved by: https://github.com/Skylion007, https://github.com/ngimel

Subject: [PATCH 0591/1424] preserve node meta to fix inductor generated kernel
 name for pattern matched graphs (#160542)

Summary:
When using inductor pattern matcher to replace graphs, the graph generated by replacement function can be missing `original_aten` metadata for the replaced nodes.  This further results in inductor failing to generate a sensible kernel name, eg. `tri_poi_fused_0` , missing the aten op name.

This diff attempts to fix that by allowing tracing the graph in replacement function with `preserve_node_meta`. Included this as an option to turn on in `pattern_matcher.fwd_only` function.

Can confirm that with the fix, MTIA's pattern matcher replaced original graph with a node that has original_aten meta, and inductor generated kernel name has op name.

Test Plan:
added kernel_name check to afg_inductor_test silu test

Rollback Plan:

Subject: [PATCH 0593/1424] [export] Relax FC requirement of serde.deserialize
 by allowing unknown fields. (#160918)

Summary:
Previously we will pass all serialized data to dataclass ctors.
Now we just loop over all the existing fields in dataclass and fetch only the field we need to run ctor.

This should help with the case when we deserializing a buffer with new field.

Test Plan:
CI

Subject: [PATCH 0595/1424] Add ScalarType -> shim conversion, add
 stable::Tensor.scalar_type (#160557)

TL;DR: Moving to ScalarType in user extensions and removing deprecated dtypes.

This change _modifies_ the from/to behavior between ScalarType and StableValue! Whereas before, user extensions could only in abstract pass around obfuscated dtypes appearing as int32_ts, now, users can confidently use torch::headeronly::ScalarType in their extensions for major scalar types. This PR enables ABI stability by adding a translation layer through the shim, so that even if the ScalarType enum values change in the future, user extensions need not fear.

Then we add a Tensor scalar_type API which reuses the from/to logic to return to the user a nice ScalarType (vs an abstracted int32_t).

I then changed the test to test the scalar_type API.

This code change required some refactoring because of circular dependencies.

## BC Breaking note
This commit is (narrowly) BC-breaking for unpopular dtypes: `quint*`s, `qint*`s, `Bits*`, `dummy_uint*`s, `dummy_int*`s, `Float8_e8m0fnu`, and `Float4_e2m1fn_x2` in the narrow use case where an extension retrieves a Tensor dtype of the above and passes it into `aoti_torch_call_dispatcher`. As of now, I believe there are 0 users of this use case, so the benefits of this change significantly justify BC-breaking this API.

Subject: [PATCH 0599/1424] Add tlparse artifact for joint graph passes (for
 inference & non-freezing only) (#160589)

Summary:
Joint graph passes run several FX passes which can modify the graph before it hits Inductor.

There's three usages of joint graph passes:
- **for inference & not freezing** (we add structured loggings only for this)
- for inference & freezing
- for fw/bw split

Subject: [PATCH 0602/1424] [SymmMem] Support rendezvous on view of a tensor
 (#160925)

`tensor.view` share the same `data_ptr()` as the original tensor, thus cannot serve as key to rendezvous' map (we want a 1:1 match between handle and tensor, thus need a unique key).

@ezyang suggests using the raw `TensorImpl*` of a tensor, for which `tensor.view` would have a different value than the original tensor.

But the raw `TensorImpl*` can be stumbled on again when a previous tensor gets deallocated and a new one allocated. For that reason, we'd also need to use a `weak_instrusive_ptr` to distinguish the two tensors, i.e. for the deallocated tensor, `weak_instrusive_ptr::expired()` would return true.

Added `test_rendezvous_view` and `test_rendezvous_same`.

Note: the view support has been added to NVSHMEM backend and NCCL backend. For CUDA backend, I have yet to investigate.

Subject: [PATCH 0603/1424] [FSDP][Replicate] replicate tests for param
 registration and input device movements (#160147)

**Summary:** In order to ensure that replicate acts as intended (a specialized version of hsdp) we need to make sure that it can pass the same tests that fully_shard can for training. To this end, I have added three test cases, one to test input device movement and the other two to test parameter registration during the forward and backward pass of a model.

**Test Cases**
1. pytest test/distributed/_composable/test_replicate_training.py -k test_root_move_forward_input_to_device
2. pytest test/distributed/_composable/test_replicate_training.py -k TestReplicateRegisteredParams

Subject: [PATCH 0608/1424] [dynamo] Refactor transform() so that instruction
 translator can be used as a tracing function. [2/n] (#160815)

We are refactoring dynamo code for convert frame so that we can have modularized pieces sharable between different compiler frontends (e.g. torch.compile, precompile and torch.export).

This PR follows the last one which separate out the part to run instruction translator on a given frame and return a DynamoTracerOutput.

The end result is a free function that runs instruction translator indepedently. A follow up diff will wrap the low level function.

Subject: [PATCH 0609/1424] [BE][Dynamo] Type coverage for symbolic_convert
 (#160922)

As part of better engineering, we add type coverage to `dynamo/symbolic_convert.py`, which is the main work engine of dynamo for emulating python bytecode.

Running
```
mypy torch/_dynamo/symbolic_convert.py --linecount-report /tmp/coverage_log
```

Subject: [PATCH 0610/1424] Add kernel information JSON generation for AOTI
 packages (#160540)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
Build on D80031559. Generate kernel_information.json in AOTI compiled artifacts by combining stack traces and node mappings from provenance tracking.

This implementation delivers exactly what Zoomer team requested:

**1. Core Function**: `create_kernel_information_json()` in debug.py combines 3 data sources:
- `_inductor_kernel_stack_trace` → `stack_traces` field
- `_inductor_triton_kernel_to_post_grad_node_info` → `post_grad_nodes` field
- `_inductor_post_to_pre_grad_nodes["postToPre"]` → `pre_grad_nodes` field

**2. AOTI Integration**: codecache.py writes `kernel_information.json` to pt2 packages when both AOTI packaging and provenance tracking are enabled.

**3. Test Coverage**: TestKernelInformationAOTI class validates:
- JSON file creation in AOTI packages using zipfile
- Exact format compliance
- Proper disabling without provenance tracking

**Output Format** (exact specification):
```json
{
  "triton_kernel_name_1": {
    "stack_traces": [str, str, ...],
    "post_grad_nodes": [str, str, ...],
    "pre_grad_nodes": [str, str, ...]
  }
}
```

Test Plan:
```
buck test fbcode//caffe2/test/inductor:provenance_tracing -- TestKernelInformationAOTI
```

Manual validation:
```python
import torch
model = torch.nn.Linear(10, 1)
with torch._inductor.config.patch("aot_inductor.package", True):
    with torch._inductor.config.patch("trace.basic_provenance_tracking", True):
        # AOTI compilation should generate kernel_information.json
        compiled = torch.export.export(model, (torch.randn(1, 10),))
```

Subject: [PATCH 0611/1424] [dcp_poc] Fix parameter order in distributed
 checkpoint API to use path-first for consistency (#160986)

Summary: This commit standardizes the parameter order across PyTorch's experimental distributed checkpoint (DCP) API, changing all checkpoint operations from (state_dict, path) to (path, state_dict) for consistency with standard file I/O patterns.

Subject: [PATCH 0614/1424] [nativert] ensure that moveable outputs are set in
 other executionframe ctor (#161005)

Summary:
so we use this constructor in HigherOrderKernel. problems arise in the loop condition, where it's possible for an output from the prev. iteration to be an input to the next. so the Output(N) of a kernel may be the Input(M) to a kernel in the next iteration. Thus, if the output value is reset (via. fastresizetozero) or overwritten by a prev. kernel before it is to be used, we have major major issues.

we need to enforce that outputs are moved, not copied, to ensure this doesn't happen.

Test Plan:

Subject: [PATCH 0617/1424] [rfc] add hint_override kwarg to mark_dynamic
 (#161007)

The motivation for this change can be seen through the following example:

```
import torch

GPU_TYPE = "cuda"

@torch.compile
def no_override(x):
    return x.sum(dim=0)

@torch.compile
def override(x):
    return x.sum(dim=0)

x_small = torch.randn(4096, 512, device=GPU_TYPE)
no_override(x_small)
torch._dynamo.decorators.mark_dynamic(x_small, 0, hint_override=4096 * 1000)
override(x_small)
```

Previously, when reductions were split, codegen relied only on the first observed shape. With a small input, this resulted in a small split size:

```
def triton_per_fused_sum_1(in_ptr0, out_ptr0, xnumel, r0_numel, XBLOCK : tl.constexpr):
    xnumel = 512
    r0_numel = 32
```

With the new scheme, inductor honors hint_override during codegen, producing larger and more appropriate split sizes:

```
def triton_red_fused_sum_0(in_ptr0, out_ptr0, xnumel, r0_numel, XBLOCK : tl.constexpr, R0_BLOCK : tl.constexpr):
    xnumel = 16384
    r0_numel = 128
```

This addresses a broader problem with dynamism: performance and numerics previously depended on whichever shape was seen first. For example:

```
f(s0) -> f(s2)
f(s1) -> f(s2)
```

could generate different kernels. With the new approach, an explicit override pins the chosen configuration:

```
f(s0, hint_override=s0) -> f(s2)
f(s1, hint_override=s0) -> f(s2)
```

ensuring consistent kernel generation regardless of input order.

Subject: [PATCH 0618/1424] [inductor] Fix descriptor broadcasting for
 singleton dimensions (#160310)

This fixes the case when an input / output contains both zero strides and singleton dimensions. In this case the broadcasting dimensions generated for the descriptor need to ignore dimensions that have zero strides with size 1, otherwise the determination of which dimensions to broadcast will fail.

As an example, consider the following store instruction:

```
name=buf1
index=x2 + 192*y0 + 64*y1
valule=TritonCSEVariable('tmp7')
params = BlockParameters(
    shape=[3, 4, 1, 1, 64],
    block_shape=[((YBLOCK + 3)//4), Min(4, YBLOCK), 1, 1, XBLOCK],
    strides=[64, 192, 0, 0, 1],
    offsets=[(yoffset//4), ModularIndexing(yoffset, 1, 4), 0, 0, xoffset]
)
broadcasting_dims=[False, False, True, True, False]
broadcast_shape=[((YBLOCK + 3)//4), Min(4, YBLOCK), XBLOCK]
```
Because `len(self.broadcasting_dims) != self.broadcast_shape)`, dim3 is incorrectly
marked as a broadcast dimension when the pre-broadcast shape is computed in `codegen_broadcast_and_reshape`.

```
9             pre_broadcast_shape = [
280                 sympy.S.One if is_broadcasting else dim
281                 for dim, is_broadcasting in zip(
282  ->                 self.broadcast_shape, self.broadcasting_dims
283                 )
284             ]
```

The pre_broadcast_shape is now wrong: `[((YBLOCK + 3)//4), Min(4, YBLOCK), 1]`

Triton throws the following error: `reshape() cannot change total number of elements in tensor`

Subject: [PATCH 0622/1424] [ATen][CPU][Sparse] Use Third-Party Eigen for
 sparse add and addmm (#155357)

This pull request adds the following ops for sparse matrices using Eigen library:
```python
    add(a_csr, b_csr)
    add(a_csc, b_csc)

    addmm(c_csr, a_csr, b_csr)
    addmm(c_csr, a_csr, b_csc)
    addmm(c_csr, a_csc, b_csc)
    addmm(c_csr, a_csc, b_csr)

    addmm(c_csc, a_csr, b_csr)
    addmm(c_csc, a_csr, b_csc)
    addmm(c_csc, a_csc, b_csc)
    addmm(c_csc, a_csc, b_csr)
```

Currently, the operations for sparse matrices on CPU are available through MKL only. The non-existence of MKL on `aarch64` causes the unavailability of these ops on any machines with ARM based CPUs, including Apple Silicon, AWS Graviton and NVIDIA Grace. This PR addresses this issue by using Eigen as a backend for the above ops.

This is a re-factored version of my previous PR #101814. The main difference with the old one, this does not enable Eigen by default.

Subject: [PATCH 0628/1424] [dynamo] Refactor convert_frame._compile_inner to
 return compiled bytecode + output graph. [3/n] (#160855)

We are refactoring dynamo code for convert frame so that we can have modularized pieces sharable between different compiler frontends (e.g. torch.compile, precompile and torch.export).

This PR adds a new helper function compile_frame() which takes a bytecode and a transform function and return compiled bytecode + output graph as DynamoOutput type.

Subject: [PATCH 0629/1424] [dynamo] Refactor convert_frame to remove usage of
 nonlocal tracer output return. [4/n] (#160899)

Today convert_frame is implemented like the following:
```
def _compile():
    tracer_output = None
    def transform():
        nonlocal tracer_output
        ...
    def _compile_inner():
         transform(...)

     compile_inner(...)
```

The code is using unconventional nonlocal variable as the return value. This is not ideal for 2 reasons:
1. Reasoning about the code, especially together with error handling code becomes harder.
2. more importantly, this makes it harder to extract out common code pieces into a shared library because everything must depend on a central global state.

In this diff we remove the usage of nonlocal return and just use the conventional function return to output the compilation data.

Subject: [PATCH 0631/1424] add static dispatch kernel registration to open
 source (#160439)

Summary: static dispatch registry should be moved to open source. the rest can maintain internally for now, since delegates will all go through ET hop.

Test Plan: spot checked existing tests and didn't see any missing registrations

Subject: [PATCH 0633/1424] Fix filename showing up as ints in dynamo_compile
 stack_trace column. (#160916)

Test plan:
$ python -m test_utils

Note:
Another way is adding the actual file_name to from_traceback, but since it's referenced in multiple places and may have associated tests this seems safer. Lmk if changes are needed @c00w

Subject: [PATCH 0634/1424] Fix SVD forward-mode AD multiplication priority
 (#161027)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Multiplication order priority for the SVD JVP appears to have been the opposite of the optimal one.

Results from a crude CPU benchmark on my laptop for random matrices of various ratios:

Subject: [PATCH 0636/1424] Add support for tracing vmap in pre-dispatch export
 (#154650)

Summary: ONNX team and recent transformer upgrade ran into this error and we also ran into during our export benchmarking. This diff makes it possible to trace through vmap implementation in pre-dispatch IR. Note that we don't support serializing functorch ops in pre-dispatch IR and in the future, we should desugar them to post-grad ops.

The implementation strategy is:
1. We add python wrappers around vmap APIs so that we attach custom torch function handler that is only on during non-strict export. The reason is we don't want to add this to default torch_function handler because it will break BC.
2. Some dynamo changes to make sure it picks up new python wrapper APIs. The reason is when we do strict export, we need to re-materialize these APIs in pre-dispatch IR from torch IR. We can avoid this by special casing in dynamo for export to proxy different API calls but i feel that is too much chaos because you need to be able to proxy 2 different variants of same vmap API.

Test Plan: CI

Subject: [PATCH 0639/1424] [ROCm] fix large tensor sort on MI350 (#161054)

Currently std::min -> ::min did not work as expected on ROCm when input values >= 2147483648

Replace `std::min` to ternary statement
Also `std::min` can be replaced by explicit typing `std::min<int64_t>`

fixes on ROCm:
test_sort_and_select.py::TestSortAndSelectCUDA::test_sort_large_cuda_float16
error:
RuntimeError: Cannot sort dimension of length 8192

Similar PR to fix large tensors on ROCm https://github.com/pytorch/pytorch/pull/130994

Subject: [PATCH 0640/1424] Try to fix Inductor CI periodic tests (#160932)

- hf_Reformer: this one starts failing due to increased graph breaks due to transformers pin bump (#159291). We can likely just bump the expected graph break count.
- dla102: this one starts timing out on 8/13 Wed between commit 6e8865f and ee1b041. But based on the PT2 dashboard, this model actually doesn't have compile time or runtime regression. Will try to bump up the timeout and see if it can work.
- hf_BigBird: this one has its accuracy status improved since today. Will update hf_BigBird accuracy status.

Subject: [PATCH 0641/1424] [pytorch] Faster and safer lambda expression
 capture in `has_integral_tensor()` (#161042)

Summary: Because `includeBool` is already a small value type (i.e., `bool`, 1 byte) that's passed by value to the function. Capturing by reference (4 or 8 bytes depending on the system) is unnecessary and could potentially lead to dangling reference issues if the lambda outlives the original variable. Capturing by value is more efficient for small types and safer.

Subject: [PATCH 0642/1424] [CI] remove tb-nightly (#160996)

Removing tb-nightly because we found issues when importing tensorboard as having both tb-nightly and tensorboard causes issues when pip would report 2.18.0 (pinned tensorboard) but importing in a python shell would report 2.13.XXX. This mismatch causes issues when running tests in a numpy2.X environment. e.g.

Subject: [PATCH 0643/1424] Decrease number of bytes used by uninitialized
 tokens_ in KernelFunction (#160764)

std::unique_ptr to decrease bytes from 24 to 8

Since std::unique_ptr is not copyable this required defining the copy / copy assignment constructors. Which made me realize we shouldn't be copying `tokens_` in those.

Subject: [PATCH 0644/1424] Close some sources of fake tensor leakages 
 (#159923)

Differential Revision: D79694055

Couple of fixes:
1. When we run into an operation we didn't proxy, we end up emitting fake constants. We detect this and error using the FQN of the lifted constant
2. Previous attribute mutation detection logic in non-strict didn't account for nested module structure. This fixes silent incorrectness issue of exporting esm and qwen in non-strict
3. We modify yolov3 to fix the previous silent incorrect behaviour

When upgrading torchbench pin, opacus_cifar10 seems to not run on eager anymore. I verified this by pushing a temporary PR on master with new pin. So i added it to expect_fail list.

Subject: [PATCH 0645/1424] flip the list-as-tuple behavior for short lists
 (#160794)

Per title, previously we started throwing noisy warnings, but given how popular this pattern was in our test suite decided to leave it as warning, not as silent behavior change for one release.
Now `treatSequenceAsTuple` would return `true` in the only case where the sequence was indeed a tuple, so no need for a special function anymore.

Subject: [PATCH 0647/1424] Conditionally enable ACL for bmm_out_or_baddbmm_
 (#161065)

Summary: Similar to #ifdef checks added in addmm_impl_cpu_ to conditionally enable ACL, we add the same checks in bmm_out_or_baddbmm_. This essentially disables ACL for bmm_out_or_baddbmm_ and enables ArmPL, which seems to be performing better.

Subject: [PATCH 0651/1424] Replace _device_t with torch.types.Device in
 torch/cpu/__init__.py (#161031)

Fixes #152952

Replace `_device_t` with `torch.types.Device` in `torch/cpu/__init__.py`. Did basic smoke test by running tests that `import torch.cpu` including `test/distributed/test_c10d_functional_native.py` and `test/test_decomp.py`.

Based this PR off of #152935 which is referenced in the main issue.

(also, this is my first contribution but I followed the contributing guide closely)

Subject: [PATCH 0652/1424] TritonKernel.inductor_meta_common() ->
 self.inductor_meta_common() (#160895)

Summary: use `self.inductor_meta_common()` to call the static method, since the custom subclasses may overwrite the method to be an instance method

Test Plan:
```
caffe2/test/inductor:select_algorithm -- test_finalized_subclass_hooks
```

Subject: [PATCH 0653/1424] [BE] Move indexing tests to test_indexing (#160994)

Which enables them on MPS device
- xfail all `test_index_reduce` on MPS, as op is not implemented
- xfail all `test_index_copy` on MPS due to the silent correctness problems, see https://github.com/pytorch/pytorch/issues/160993
- Fixed hard crash in `index_fill` and replaced `skipIfMPS` with `expectedFailueMPS`
- Created issue for the lack of deterministic algorithms for MPS backend

Subject: [PATCH 0654/1424] Workaround ATen SFINAE under libc++ (#161101)

The existing logic here to workaround dealing with SFINAE under Microsoft platforms also applies to libc++ platforms. It appears that nvcc reports ambiguity in overload resolution for `pow_`. This seems like a nvcc limitation.

```
fbcode/caffe2/aten/src/ATen/native/cuda/Pow.cuh(42): error: more than one instance of overloaded function "pow" matches the argument list:
            function template "std::__2::enable_if<<expression>, std::__2::__promote<_A1, _A2, void>>::type::type pow(_A1, _A2) noexcept" (declared at line 848 of fbcode/third-party-buck/platform010-libcxx/build/libcxx/include/c++/v1/math.h)
            function template "std::__2::enable_if<<expression>, std::__2::__promote<_Tp, _Up, void>>::type pow(_Tp, _Up) noexcept" (declared at line 11308 of fbcode/third-party-buck/platform010/build/cuda/12.4/bin/..//include/crt/math_functions.h)
            argument types are: (double, float)
    return ::pow(base, exp);
           ^
```

Subject: [PATCH 0655/1424] don't try to set lazy module loading env var
 (#161103)

This is not needed on drivers >=525, and in DriverAPI::get() we are initializing the context anyway, so setting environment variable after that is beside the point
As a result of calling DriverAPI::get on systems that don't have gpus available (e.g. due to CUDA_VISIBLE_DEVICES="") people were getting confusing errors.

Reverted https://github.com/pytorch/pytorch/pull/160147 on behalf of https://github.com/jithunnair-amd due to Sorry, but looks like this broke ROCm distributed CI ([comment](https://github.com/pytorch/pytorch/pull/160136#issuecomment-3208632921))

Subject: [PATCH 0658/1424] Revert "[FSDP][Collectives] skipping reduce_scatter
 when world size is 1 (#160136)"

This reverts commit 3d126e17e0c2630031e7a359d6a6fd1dbe52c4f7.

Reverted https://github.com/pytorch/pytorch/pull/160136 on behalf of https://github.com/jithunnair-amd due to Sorry, but looks like this broke ROCm distributed CI ([comment](https://github.com/pytorch/pytorch/pull/160136#issuecomment-3208632921))

Subject: [PATCH 0659/1424] [rfc] add hint_override kwarg to mark_dynamic
 (#161007)

The motivation for this change can be seen through the following example:

```
import torch

GPU_TYPE = "cuda"

@torch.compile
def no_override(x):
    return x.sum(dim=0)

@torch.compile
def override(x):
    return x.sum(dim=0)

x_small = torch.randn(4096, 512, device=GPU_TYPE)
no_override(x_small)
torch._dynamo.decorators.mark_dynamic(x_small, 0, hint_override=4096 * 1000)
override(x_small)
```

Previously, when reductions were split, codegen relied only on the first observed shape. With a small input, this resulted in a small split size:

```
def triton_red_fused_sum_0(in_ptr0, out_ptr0, ks0, xnumel, r0_numel, XBLOCK : tl.constexpr, R0_BLOCK : tl.constexpr):
    xnumel = 16384
    rnumel = r0_numel
```

With the new scheme, inductor honors hint_override during codegen, producing larger and more appropriate split sizes:

```
def triton_red_fused_sum_0(in_ptr0, out_ptr0, ks0, xnumel, r0_numel, XBLOCK : tl.constexpr, R0_BLOCK : tl.constexpr):
    xnumel = 1024000
    rnumel = r0_numel
```

This addresses a broader problem with dynamism: performance and numerics previously depended on whichever shape was seen first. For example:

```
f(s0) -> f(s2)
f(s1) -> f(s2)
```

could generate different kernels. With the new approach, an explicit override pins the chosen configuration:

```
f(s0, hint_override=s0) -> f(s2)
f(s1, hint_override=s0) -> f(s2)
```

ensuring consistent kernel generation regardless of input order.

Subject: [PATCH 0663/1424] Fix torchaudio build when TORCH_CUDA_ARCH_LIST is
 not set (#161084)

Fixes https://github.com/pytorch/pytorch/issues/160988.  The root cause can be found in the same issue.  This fix ensures that when reuse old wheel is on and `torchaudio` wheel is not there, the inductor test job can still rebuild the wheel it needs

Subject: [PATCH 0667/1424] [inductor] Estimate peak memory allocfree and
 applying to reordering collectives (#160113)

1. Applying @eellison idea from https://github.com/pytorch/pytorch/pull/146562#discussion_r2059363672 for estimate_peak_memory:
```
    """
    Alternative version of estimate_peak_memory, that respects the fact,
    that every SchedulerNode has multiple phases:
    1. alloc ( outputs )
    2. run_kernel
    3. dealloc last_use buffers
    estimate_peak_memory collapses memory into one value: size_alloc - size_free
    While peak memory happens after alloc.

    Duplicating the code to not migrate all callsites at once,
    In future usages of estimate_peak_memory will migrate to this version.
    """
```

- Applying this in `reorder_communication_preserving_peak_memory` pass.

2. Buffers during reordering can change deallocation point, if candidate and group to swap both are users of the f_input_buf and group contains last_use_snode.

- Addressing this tracking the last_use_snode for each buffer and recomputing current memory respecting the change in size_free (group_node after reordering is not the last user of the buffer and its size_free -= buffer_size, while candidate becomes the last user and candidate.size_free += buffer_size).

4. Adding env var `PYTORCH_REORDER_COLLECTIVES_LIMIT` for ablation to limit number of collectives to reorder.

What is after this PR:

Iterative recomputation of memory estimations matches full memory estimations.

Active memory is not regressing a lot, but reserved memory is significantly regressed.

Investigation and fix of "reserved" memory will be in following PRs.

Subject: [PATCH 0672/1424] [Quant][CPU] Avoid NaN in fp8 output of qlinear and
 qconv (#160957)

**Summary**
When output dtype is fp8, oneDNN does not ensure intermediate results in the range of [-448, 448] before converting to fp8. So, we may get NaN in the output, which is a disaster for inference. This PR fixes this issue by clamping the intermediate results by oneDNN's post-op clip.

**Test plan**
```
pytest -sv test/quantization/core/test_quantized_op.py -k "q and fp8"
```

Subject: [PATCH 0675/1424] [inductor] Estimate peak memory allocfree and
 applying to reordering collectives (#160113)

1. Applying @eellison idea from https://github.com/pytorch/pytorch/pull/146562#discussion_r2059363672 for estimate_peak_memory:
```
    """
    Alternative version of estimate_peak_memory, that respects the fact,
    that every SchedulerNode has multiple phases:
    1. alloc ( outputs )
    2. run_kernel
    3. dealloc last_use buffers
    estimate_peak_memory collapses memory into one value: size_alloc - size_free
    While peak memory happens after alloc.

    Duplicating the code to not migrate all callsites at once,
    In future usages of estimate_peak_memory will migrate to this version.
    """
```

- Applying this in `reorder_communication_preserving_peak_memory` pass.

2. Buffers during reordering can change deallocation point, if candidate and group to swap both are users of the f_input_buf and group contains last_use_snode.

- Addressing this tracking the last_use_snode for each buffer and recomputing current memory respecting the change in size_free (group_node after reordering is not the last user of the buffer and its size_free -= buffer_size, while candidate becomes the last user and candidate.size_free += buffer_size).

4. Adding env var `PYTORCH_REORDER_COLLECTIVES_LIMIT` for ablation to limit number of collectives to reorder.

What is after this PR:

Iterative recomputation of memory estimations matches full memory estimations.

Active memory is not regressing a lot, but reserved memory is significantly regressed.

Investigation and fix of "reserved" memory will be in following PRs.

Subject: [PATCH 0679/1424] Fix torchaudio build when TORCH_CUDA_ARCH_LIST is
 not set (#161084)

Fixes https://github.com/pytorch/pytorch/issues/160988.  The root cause can be found in the same issue.  This fix ensures that when reuse old wheel is on and `torchaudio` wheel is not there, the inductor test job can still rebuild the wheel it needs

Subject: [PATCH 0680/1424] Allow bypasses for Precompile when guards, etc.
 cannot be serialized (#160902)

This adds a new function `bypass_package` and `CompilePackage.bypass_current_entry()`. This allows us to safely bypass if there are models with unserializable or incompatible parts. When we encounter something incompatible, we'll raise a bypass and ignore that particular code in DynamoCodeEntry.

Subject: [PATCH 0682/1424] [pytorch] Invoke `vector.reserve()` consistently
 for non-inplace foreach operations (#161128)

Summary:
The `reserve()` method is used to pre-allocate memory for the result vector before adding elements to it. This is an optimization that makes sense for several reasons:

1. Performance improvement: By pre-allocating memory for the exact number of elements needed, it avoids multiple reallocations and memory copies that would occur as the vector grows dynamically.

2. Memory efficiency: It ensures that the vector allocates exactly the amount of memory needed, no more and no less, which is efficient when we know the final size in advance.

3. Reduced overhead: Each reallocation typically involves:
- Allocating a new, larger block of memory
- Copying all existing elements to the new location
- Destroying the old elements
- Deallocating the old memory block
- Consistent performance: Without reservation, vector growth typically follows a geometric progression (like 1, 2, 4, 8, 16...), which can lead to unpredictable performance spikes when reallocation occurs.

+    Graph-safe RNG lets torch.compile use CUDA Graphs for graphs with RNG ops.
+    For graphs without HOPs, the partitioner adds placeholder nodes
+    fwd_rng_state_* and bw_rng_state_* to the forward and backward graphs. At
+    runtime, the AOTDispatcher retrieves these RNG states and passes them to the
+    compiled graphs.
+
+    This works well for no-HOP graphs. With HOPs, the partitioner runs
+    recursively: it first partitions the HOP (producing forward/backward HOP
+    subgraphs) and then stitches them back into the outer joint graph. For HOPs
+    that contain RNG ops, the outer joint graph now includes HOP subgraph
+    modules with extra RNG placeholders. We must thread these placeholders
+    through the outer module partitioned forward and backward graphs—this
+    function does exactly that. It collects the RNG placeholder nodes from the
+    HOPs and creates corresponding placeholders in the outer forward and
+    backward graphs.
+
+    There is a catch: for a short period, the joint graph is in a “bad” state.
+    The HOP subgraphs expect additional inputs (because of the new
+    placeholders), but the outer graph call sites don't yet provide them. We
+    can't fix this in the joint graph because the joint graph's input signature
+    is fixed (primals, tangents). As a compromise, we keep the joint graph in
+    somewhat of a bad state for some time and, once the outer forward and
+    backward graphs are partitioned, insert the corresponding RNG placeholders

Subject: [PATCH 0687/1424] Fix constant_pad_nd_mps bug when pad is empty
 (#161149)

Fixes #161066

There is a size check here, which causes the error.
https://github.com/pytorch/pytorch/blob/8ce81bcee1da294a34af0a90dc16483055e8c5a4/aten/src/ATen/native/mps/operations/Pad.mm#L39-L40

If the argument `pad` is empty, it will return the cloned tensor on CPU.

https://github.com/pytorch/pytorch/blob/8ce81bcee1da294a34af0a90dc16483055e8c5a4/aten/src/ATen/native/PadNd.cpp#L43-L64

Therefore, this PR fixes the empty padding argument error by checking the size first and returning a cloned tensor immediately if the padding size is 0.

Subject: [PATCH 0689/1424] [dcp][hf] Fix multi-rank consolidation for no files
 to process case (#160660)

Summary: In the consolidate_safetensors_files_on_every_rank method, where we use multiple ranks to combine sharded safetensors files, if there are more ranks in the world size, than there are safetensors file to consolidate, then some ranks don't have to do any work. When I had tested, this case wasn't caught, and there was an extra barrier call, causing issues for the ranks that had no work to do. They should wait at the end, as do the ranks with work.

Test Plan:
tested this case on a job e2e
added a unit test

Rollback Plan:

Subject: [PATCH 0691/1424] [VLLM]setup test cli logics (#160361)

setup vllm test logics.
1.  install wheels generated from previous build stage
2. generate and install vllm test pkg list on run time based on the torch wheels in the instance
3. run test based on the pre-defined test plan

notice the test-plan format is temporary for some basic vllm testing

Subject: [PATCH 0692/1424] [DTensor] Make default RNG semantics match
 user-passed generator (#160482)

Previously, DTensor kept its own copy of the generator state after the
first time a random operator was called on a DTensor. This copy would
evolve independently from the generator outside of DTensor.

After adding support for users to pass a specific generator into
random operators (e.g. `uniform_(..., generator=)`), it was determined
(in discussion on #159991) to change the semantics so that any random
operations performed on DTensor would evolve the state of the publicly
visible generators (either the default one or user-passed one).

The upsides are (1) it is now possible to call torch.manual_seed() at
any point in the program and have a consistent effect on DTensor, (2)
DTensor ops have an observable effect on the generator.  The downside is
that users are now responsible for seeding their generator before using
DTensor, ensuring all ranks use the same seed.

Fixes #159991

+### Random Operations
+
+DTensor provides distributed RNG functionality to ensure that random operations on sharded tensors get unique values, and random operations on replicated tensors get the same values. This system requires that all participating
+ranks (e.g. SPMD ranks) start out using the same generator state before each dtensor random operation is performed,
+and if this is true, it ensures they all end up at the same state after each dtensor random operation completes. There is no communication performed during random operations to synchronize RNG states.
+
+Operators that accept a `generator` kwarg will utilize the user-passed generator, if passed, or the default generator for the device otherwise. Whichever generator is used, it will be advanced after the DTensor operation.  It is valid to use the same generator for both DTensor and non-DTensor operations, but care must be taken to ensure the non-DTensor operations advance the generator state equally on all ranks if so.
+
+When using DTensor together with Pipeline Parallelism, ranks for each pipeline stage should use a distinct seed, and ranks within a pipeline stage should use the same seed.
+
+DTensor's RNG infra is based on the philox based RNG algorithm, and supports any philox based backend (cuda, and other cuda-like devices), but unfortunately does not yet support the CPU backend.

Subject: [PATCH 0694/1424] [BE] Enable
 `test_index_put_accumulate_duplicate_indices` on MPS (#161201)

By changing dtype to float if device is MPS

Note: for some reason test runs much longer on MPS than on CPU
```
% python ../test/test_indexing.py -v -k test_index_put_accumulate_duplicate_indices_mps
test_index_put_accumulate_duplicate_indices_mps (__main__.TestIndexingMPS.test_index_put_accumulate_duplicate_indices_mps) ... ok

----------------------------------------------------------------------
Ran 1 test in 9.139s

OK
```

Subject: [PATCH 0695/1424] Revert "[ATen][CPU][Sparse] Use Third-Party Eigen
 for sparse add and addmm (#155357)"

This reverts commit ce048de608180fa88335e5821070472539968b54.

Reverted https://github.com/pytorch/pytorch/pull/155357 on behalf of https://github.com/seemethere due to This is causing buck builds to fail since we didn't add the definition of AT_USE_EIGEN_SPARSE in the buckbuild.bzl file, will follow-up and re-land this. ([comment](https://github.com/pytorch/pytorch/pull/155357#issuecomment-3212270510))

Subject: [PATCH 0699/1424] Avoid making node a successor/predecessor of itself
 (#161205)

This fixes an assertion we were running into in the memory planning about not having an acyclic graph. The repro is very long so hard to make local test of, but fixes repro I am looking at.

Subject: [PATCH 0700/1424] [export] Remove unused Model, tensor_paths,
 constant_paths (#161185)

Summary:
Removed `Model`, it's not being used anywhere so it's safe.

Removed `tensor_paths` and `constant_paths` fields in `ExportedProgram`
- BC: when the current deserializer load a previously serialized EP (that comes with empty `tensor_paths` and `constant_paths`), it will just ignore those two fields
- FC: when the old deserializer load a newly serialized EP (that doesn't come with `tensor_paths` and `constant_paths`, it will also ignore those two fields in `_dict_to_dataclass()`

Differential Revision: D80725094

The `native_transformers_hip_hip` and `native_transformers_hip_cpp` sources are okay to define (and are required) even if accelerated versions of these operations are not available.

I've tested downstream builds of torch with ROCm on native Windows via https://github.com/ROCm/TheRock both with and without aotriton and these changes were needed for the build to succeed in both cases. I have _not_ tested Linux, WSL, or with the HIP SDK.

Subject: [PATCH 0703/1424] Log exception_stack_trace to dynamo_compile
 (#161096)

Note: Adding unit test for this is tricky as having errors in the specific unit test would cause test_utils.py to crash all together.

Tested as follows:
1. Added x = 1/0 after guarded_code = compile_inner(code, one_graph, hooks, transform) in convert_frame.py
2. Printed exception_stack_trace and got: ['Traceback (most recent call last):\n  File "/data/users/jovian/pytorch/torch/_dynamo/convert_frame.py", line 1207, in _compile\n    x = 1/0\n        ~^~\nZeroDivisionError: division by zero\n']

Subject: [PATCH 0704/1424] [inductor][cpu] Fix double-offset issue in
 `GEMM_TEMPLATE` (#159233)

Fixes #158076

Basically, the gemm template generates code like
```
cpp_CppMicroGemmRef_micro_gemm<static_cast<bool>(false), static_cast<bool>(false)>(
            &(X[static_cast<int64_t>(k_start + 196LL*m_start + 38416LL*ks_b_index)]),
            &(W[static_cast<int64_t>(200704000LL + n_start + 80LL*k_start + 15680LL*ks_b_index)]),
            &(local_acc_buf[static_cast<int64_t>(Nr*nci + ((-1LL)*Nr*nc))]),
            static_cast<int64_t>(m_end + ((-1LL)*m_start)),
            static_cast<int64_t>(Nr),
            static_cast<int64_t>(k_end + ((-1LL)*k_start)),
            static_cast<int64_t>(196LL),
            static_cast<int64_t>(80LL),
            static_cast<int64_t>(Nc_blocks*Nr)
        );
```

However, when the input tensor W has a storage offset, this results in a double offset issue. That is, the resulting pointer is `2 * 200704000LL` away from `W.storage().data_ptr()`, which causes an out-of-bounds access.

The storage offset of `W` is introduced by [this patch](https://github.com/pytorch/pytorch/pull/136421/files), but I think it's a reasonable fix. So `cpp_gemm_template.py` should handle input matrices with storage offsets properly.

I think a good way to fix this issue is to create a new matrix that has no storage offset.

When `should_block_weights` is true, `block_weight()` creates a clean new matrix, so that branch is not affected by this issue.

BTW I've also examined the FX IRs generated by `torch.compile()`, as well as the generated python module, and they are correct.

The newly-added test in `test_cpu_select_algorithm.py` can reproduce the issue. With this patch, the crash is fixed. It also resolves the crash reported in #158076.

I ran CPU tests in `test_cpu_select_algorithm.py`, but many of them are skipped due to MKL and AMX. I'd be appreciated if someone can help verify the test.

Subject: [PATCH 0707/1424] [dynamo] propagate tensor metadata on
 Tensor.__setitem__(tensor) (#161036)

Fixes silent incorrectness for autograd function tracing, where we rely on FakeTensor metadata (requires_grad) to determine whether to HOP or not: https://github.com/pytorch/pytorch/blob/5ee464db5c4293ac09521f9069fa7d2106680a7f/torch/_dynamo/variables/misc.py#L671

Stared at this with @anijain2305 yesterday, `Tensor.__setitem__` can update tensor metadata, and we can just run the fake prop and extract the output metadata from the updated FakeTensor.

FIXES https://github.com/pytorch/pytorch/issues/160901

It should also be the root cause behind the issue in https://github.com/pytorch/torchtitan/pull/1604 @bdhirsh  @ruisizhang123

Subject: [PATCH 0709/1424] [BE] Remove the default TORCH_CUDA_ARCH_LIST in CI
 Docker image (#161137)

This doesn't make sense to have this default to Maxwell, which is too old.  All other places in CI/CD needs to overwrite this value.  IMO, it makes more sense to not set this at all and let CI/CD jobs set it for their own use cases instead.  This is partly responsible for the build failure in https://github.com/pytorch/pytorch/issues/160988

Subject: [PATCH 0714/1424] Disable background threads for XPU host allocator
 (#161242)

# Motivation
https://github.com/pytorch/pytorch/pull/160505 enables background threads for XPU host allocator. However, it will hang on Windows during program exit. Now disable it until we narrow down the issue.

Subject: [PATCH 0720/1424] Add CUDA 13.0 x86 builds (#160956)

https://github.com/pytorch/pytorch/issues/159779

CUDA 13.0.0
NVSHMEM 3.3.20
CUDNN 9.12.0.46

Adding x86 linux builds for CUDA 13.
Adding libtorch docker.
Package naming changed for CUDA 13 (removed postfix -cu13 for some packages).

Preparation checklist:
1. Update index https://download.pytorch.org/whl/nightly/cu130 with pypi packages
2. Update packaging name based on https://pypi.org/project/cuda-toolkit/ metadata

Pull Request resolved: https://github.com/pytorch/pytorch/pull/160956
Approved by: https://github.com/atalman

Subject: [PATCH 0722/1424] [inductor] Estimate peak memory allocfree and
 applying to reordering collectives (#160113)

1. Applying @eellison idea from https://github.com/pytorch/pytorch/pull/146562#discussion_r2059363672 for estimate_peak_memory:
```
    """
    Alternative version of estimate_peak_memory, that respects the fact,
    that every SchedulerNode has multiple phases:
    1. alloc ( outputs )
    2. run_kernel
    3. dealloc last_use buffers
    estimate_peak_memory collapses memory into one value: size_alloc - size_free
    While peak memory happens after alloc.

    Duplicating the code to not migrate all callsites at once,
    In future usages of estimate_peak_memory will migrate to this version.
    """
```

- Applying this in `reorder_communication_preserving_peak_memory` pass.

2. Buffers during reordering can change deallocation point, if candidate and group to swap both are users of the f_input_buf and group contains last_use_snode.

- Addressing this tracking the last_use_snode for each buffer and recomputing current memory respecting the change in size_free (group_node after reordering is not the last user of the buffer and its size_free -= buffer_size, while candidate becomes the last user and candidate.size_free += buffer_size).

4. Adding env var `PYTORCH_REORDER_COLLECTIVES_LIMIT` for ablation to limit number of collectives to reorder.

What is after this PR:

Iterative recomputation of memory estimations matches full memory estimations.

Active memory is not regressing a lot, but reserved memory is significantly regressed.

Investigation and fix of "reserved" memory will be in following PRs.

-### Random Operations
-
-DTensor provides distributed RNG functionality to ensure that random operations on sharded tensors get unique values, and random operations on replicated tensors get the same values. This system requires that all participating
-ranks (e.g. SPMD ranks) start out using the same generator state before each dtensor random operation is performed,
-and if this is true, it ensures they all end up at the same state after each dtensor random operation completes. There is no communication performed during random operations to synchronize RNG states.
-
-Operators that accept a `generator` kwarg will utilize the user-passed generator, if passed, or the default generator for the device otherwise. Whichever generator is used, it will be advanced after the DTensor operation.  It is valid to use the same generator for both DTensor and non-DTensor operations, but care must be taken to ensure the non-DTensor operations advance the generator state equally on all ranks if so.
-
-When using DTensor together with Pipeline Parallelism, ranks for each pipeline stage should use a distinct seed, and ranks within a pipeline stage should use the same seed.
-
-DTensor's RNG infra is based on the philox based RNG algorithm, and supports any philox based backend (cuda, and other cuda-like devices), but unfortunately does not yet support the CPU backend.

From 25df65afd8b5e2fffbcaf2b7ed63ef7a1e37ecb9 Mon Sep 17 00:00:00 2001
From: Jeff Daily <jeff.daily@amd.com>

Subject: [PATCH 0729/1424] [ROCm] revamp HIPCachingAllocatorMasqueradingAsCUDA
 (#161221)

HIPAllocatorMasqueradingAsCUDA and HIPCachingAllocatorMasqueradingAsCUDA are now proper complete wrappers of HIPAllocator and HIPCachingAllocator, respectively. HIPAllocatorMasqueradingAsCUDA now subclasses HIPAllocator instead of Allocator. This fixes usability of hipify replacing c10::cuda::CUDACachingAllocator::get() where callers expect a CUDAAllocator to be returned but instead were getting a very thin Allocator shim instead.

This also fixes using cudagraph trees with torch compile. The hip:0 device was not being replaced by the cuda:0 device in all methods.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161221
Approved by: https://github.com/jeffdaily

Subject: [PATCH 0730/1424] remove old while_loop_schema_gen test (#161202)

Fixes https://github.com/pytorch/pytorch/issues/141202.

This test is flaky for mysterious reasons and we have created a new way of creating schemas for hops. So delete the test.

Subject: [PATCH 0732/1424] [inductor] Add get page_size support for Windows.
 (#161273)

`resource` can't work on Windows, as it is a Unix specific package as seen in https://docs.python.org/2/library/resource.html

Use Windows system API to get page_size.

Local tested:

Subject: [PATCH 0737/1424] Fix conv exhaustive autotuning and expand
 Exhaustive test coverage (#159387)

Conv exhuastive currently throws an error, and I think it's worth adding tests to the other ops too in order to prevent regression in exhaustive.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/159387
Approved by: https://github.com/coconutruben

Subject: [PATCH 0740/1424] [cuDNN] head dim > 128 works on H100 again in cuDNN
 SDPA?  (#161210)

reference: https://github.com/pytorch/torchtitan/pull/1610

9.10 only for now, we would want to hold off on upgrading to either cuDNN frontend 1.14+/cuDNN 9.11+ due to some head-dim > 128 handling issues

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161210
Approved by: https://github.com/Skylion007

Subject: [PATCH 0741/1424] [benchmark] Add torchscript jit.trace to benchmark
 option (#161223)

For comparing NativeRT and TorchScript. We add `torchscript-jit-trace` as an option in the benchmark. With this option, we can run trace a model and run inference with the traced module using TorchScript interpreter

```
python ./benchmarks/dynamo/huggingface.py --performance --inference --torchscript-jit-trace

python ./benchmarks/dynamo/timm_models.py --performance --inference --torchscript-jit-trace

python ./benchmarks/dynamo/torchbench.py --performance --inference --torchscript-jit-trace
```

Subject: [PATCH 0744/1424] [Profiler] Add GC Events to Python Stack Tracer
 (#161209)

Summary:
Adds Python Garbage Collection to Kineto Traces and Profiler FunctionEvents. Create custom cpp callback in profiler_python.cpp. Then define a python function with cpp and register that callback for all python garbage collection. We don't worry about thread safety in this case because we are only doing init/teardown for main thread while holding GIL.

Currently we are hiding this behind experimental config because python tracing tends to be unstable especially when adding any new feature. If this is found to not add too much overhead we can set this to on by default. NOTE: To enable this you need both with_stack=True and the experimental config on!

Test Plan:
Ran trace with GC induced and saw it on trace

Also added a test

Rollback Plan:

Subject: [PATCH 0745/1424] [ONNX] Remove enable_fake_mode and exporter_legacy
 (#161222)

Remove enable_fake_mode and exporter_legacy entirely. Even though this is bc breaking, `enable_fake_mode` is no longer compatible with the latest version of transformers, and so it is no longer useful.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161222
Approved by: https://github.com/titaiwangms

Subject: [PATCH 0751/1424] [Inductor-FX] Support Tensorbox outputs (#161245)

# Problem
The FX converter previously supported graph outputs which were `StorageBox`, but not `TensorBox`. The latter seems to show up in certain cases when the output is a slice/view of the input.

# Fix
This PR generalizes the code to handle `MutableBox` instead of `StorageBox` specifically.

# Test
Added a CI test exposing the issue. The test case was found by intentionally breaking `TensorBox(ReinterpretView` support in https://github.com/pytorch/pytorch/pull/161258.

Subject: [PATCH 0752/1424] [MPS] Update `avg_pool2d` to use Metal kernel when
 `ceil_mode=True` (#161011)

Fixes #160743

The MPS impl of `avg_pool2d` seems to only give incorrect results when `ceil_mode=True`. I wrote a performance measurement script (https://github.com/kurtamohler/pytorch-perf-test-scripts/blob/0ee6e586431fc3a0035a1d1d2ce06931d913ade5/avg_pool_mps/perf_2d.py) which tests a bunch of different cases and also marks the cases where MPS and CPU results do not match.

I found that if I update `avg_pool2d` to use the new Metal kernel in all cases, that fixes all the mismatches, but it also decreases performance for some of the `ceil_mode=False` cases. So I opted to only run the new Metal kernel when  `ceil_mode=True`, which does not significantly decrease performance in any of the cases tested.

Subject: [PATCH 0757/1424] [ONNX] Fix lower opset version support in
 dynamo=True (#161056)

After we switched to constructing the registry with the specified opset version in dynamo=True, support for opset<18 was broken because there would be no torchlib ops registered for these opsets. I updated the registry creation logic to always use opset 18 if the requested opset is lower, and use the version converter (as designed) to target those opsets.

This requires onnxscript>=0.4 (https://github.com/pytorch/pytorch/pull/161312)

Fixes https://github.com/onnx/onnx/issues/7235

Users encountered unexpected behaviour when using FlexAttention with learnable biases, including assertion errors (#157677)

We traced the root cause to the registration of subgraph buffers—this caused inconsistencies in the naming and ultimately incorrect retrieval later on. This problem only arose if the model was compiled as a whole (ie using @torch.compile) since only then would there be naming conflicts.

In this PR, we register the buffers with the base graph to solve this issue.

Subject: [PATCH 0763/1424] [AMD] Fix AMD User Defined Kernel Autotune
 (#160671)

Summary: AMD specific kwargs need to be removed from the guard, otherwise a keyerror will be raised when executing the kernel.

Test Plan:
```
buck2 run mode/opt-amd-gpu -m rocm641 -c fbcode.split-dwarf=true -c fbcode.use_link_groups=true -c fbcode.enable_gpu_sections=true //hpc/new/models/feed/benchmark:feed_lower_benchmark -- --load=manifold://ads_storage_fblearner/tree/user/facebook/fblearner/predictor/894698382/0/gpu_lowering/new_input8 --skip-eager --skip-flop-estimation --sync-mode=0 --lower-backend=AOT_INDUCTOR
```
can succeed after this change.

Subject: [PATCH 0764/1424] Support NUMA Binding for Callable Entrypoints, Take
 2 (#161183)

# Context
In #160163, we added support for NUMA binding for `Callable` entrypoints to `elastic_launch`. This requires special consideration, because they go through a different path to spawn subprocesses compared to `str` entrypoints, a path which does not provide a straightforward way to utilize `numactl` CLI. See #160006 for a full description of the challenges.

Although #160163 worked in initial local experiments, we ran into some linker errors in other environments when we tried to call `numactl`. This appeared to be due to interactions with how the `LD_PRELOAD` environment variable was being set.

# This PR
On further thought, the most straightforward, foolproof solution here is to use [the trick that @d4l3k suggested.](https://github.com/pytorch/pytorch/issues/160006#issuecomment-3162018836)

Specifically, for each local rank `i`:
1. The parent process sets its own CPU affinity to what local rank `i`'s should be.
2. Then, the parent spawns the subprocess for local rank `i`.
3. Finally, the parent resets its own CPU affinity to what it was originally.

There were other solutions that would work just for `Callable` entrypoints, but I believe this is the simplest one that can work for *both* `str` and `Callable`, and it's pretty simple.

This required a bit of refactoring:
1. Turn all the `_get_.*_numactl_options` into functions which return a set of logical CPUs to bind to, rather than options like `--cpunodebind=0`.
2. Instead of wrapping commands with `numactl`, use `os.sched_setaffinity` to bind to the CPUs from (1.).
3. Put this all inside a context manager which encapsulates applying and restoring the bindings in the parent process.
4. Use the context manager for both `str` and `Callable` paths

# Test Plan
## Automated
`$ pytest test/test_numa_binding.py`

## Manual
See [doc.](https://docs.google.com/document/d/1vxD-OKYBTT27jbBwtW9iz9g0tNM0u-i0tiTJg_ieQA8/edit?tab=t.0) Meta only, but TLDR tried out every combination of `str`, `Callable`, binding disabled, and binding enabled on the same model and saw 2x SM utilization for binding enabled.

Subject: [PATCH 0765/1424] Revert "Move non inductor workflows to Python 3.9
 -> 3.10 (#161182)"

This reverts commit e20f6d798606f3245686e950c43635bbe526232d.

Reverted https://github.com/pytorch/pytorch/pull/161182 on behalf of https://github.com/zou3519 due to broke dynamo_wrapped tests, those are a bit finicky to fix (there is probably more than one failure!) ([comment](https://github.com/pytorch/pytorch/pull/161182#issuecomment-3216953097))

Subject: [PATCH 0767/1424] [ATen][CPU][Sparse] Use Third-Party Eigen for
 sparse add and addmm (#155357)

This pull request adds the following ops for sparse matrices using Eigen library:
```python
    add(a_csr, b_csr)
    add(a_csc, b_csc)

    addmm(c_csr, a_csr, b_csr)
    addmm(c_csr, a_csr, b_csc)
    addmm(c_csr, a_csc, b_csc)
    addmm(c_csr, a_csc, b_csr)

    addmm(c_csc, a_csr, b_csr)
    addmm(c_csc, a_csr, b_csc)
    addmm(c_csc, a_csc, b_csc)
    addmm(c_csc, a_csc, b_csr)
```

Currently, the operations for sparse matrices on CPU are available through MKL only. The non-existence of MKL on `aarch64` causes the unavailability of these ops on any machines with ARM based CPUs, including Apple Silicon, AWS Graviton and NVIDIA Grace. This PR addresses this issue by using Eigen as a backend for the above ops.

This is a re-factored version of my previous PR #101814. The main difference with the old one, this does not enable Eigen by default.

Subject: [PATCH 0768/1424] Use -compress-mode=size for CUDA 13 build for
 binary size reduction (#161316)

https://github.com/pytorch/pytorch/issues/159779

CUDA 13 added the support for --compress-mode flag for nvcc across all drivers of CUDA 13.X toolkits, enabling the possibility to use --compress-mode=size for significant size reduction (~71% less for CUDA Math APIs for example). https://developer.nvidia.com/blog/whats-new-and-important-in-cuda-toolkit-13-0/

Why we have to add for CUDA 13 only, quote from @ptrblck : Any usage of --compress-mode=size/balance will drop the support of older CUDA drivers and will bump the min. driver requirement to CUDA 12.4. https://github.com/pytorch/pytorch/pull/157791#issuecomment-3058027353

Default for CUDA 13 will be --compress-mode=balance which gives smaller binaries than LZ4 speed mode used in previous CUDA versions.

Subject: [PATCH 0769/1424] [muon] Introduce Muon optimizer to PyTorch
 (#160213)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A single-device version of Muon. Algorithm refers Keller Jordan's [Muon blogpost](https://kellerjordan.github.io/posts/muon/), and optionally incorporates [Moonshot's](https://github.com/MoonshotAI/Moonlight/blob/master/Moonlight.pdf) learning rate adjustment strategy.

This implementation maintains a minimalist API and is consistent with other optimizer conventions. PyTorch team prefers to handle parameter filtering at a higher level, with the Muon optimizer performing only the msign computation for orthogonalization on all parameters it receives. Users are responsible for grouping parameters for different optimizers as needed. An example usage is shown below, and a more detailed example will be added to the [PyTorch examples](https://github.com/pytorch/examples) directory.

**Usage**

```python
    model = MyModelForCausalLM
    # filter out your params manually
    muon_params = [...]
    adamw_params = [...]
    muon = Muon(
        params = muon_params
        lr=lr,
        wd=wd,
    )
    adamw = AdamW(
        params = adamw_params
        lr=lr,
        wd=wd,
    )

    # in training loop

```

~~**Additional usage**~~
~~Users are also able to pass in self-defined `msign` function for orthogonalization, and learning rate adjustment function. Interface defined below:~~

```python
~~AdjustLrFn: TypeAlias = Callable[[float, torch.Size], float]~~
~~MsignFn: TypeAlias = Callable[[Tensor, BaseMsignFnConfig], Tensor]~~
```

As discussed with team and in comment, we prefer to make the interface simpler and cleaner, thus we removed the callback interface, and canonicalize the original NS algorithm for Muon. The only configs available to users are `ns_steps`, `coefficients`, and `eps`, configurable through kwargs.

By default, we use 5-step Newton-Schulz, with coefficients proposed by [Keller](https://kellerjordan.github.io/posts/muon/). We use LR adjustment proposed by [Moonshot](https://github.com/MoonshotAI/Moonlight/blob/master/Moonlight.pdf), which grafts learning rate from AdamW.

**Testing**

~~1. Unit tests: the newly introduced Muon is covered in `test/test_optim.py`. We updated the test cases to pass named parameters to the optimizer under test. Additionally, we introduced a new test case to verify that when the user provides an empty FQN list, Muon correctly falls back to AdamW behavior.~~

As discussed, in order not to complicate the codebase, we prefer not to include reference implementation into PyTorch. We also updated the interface so we don't need to test the FQN based filtering. Muon is covered by the existing `test_optim.py` unit test.

2. End-to-end test: we added a training script that pre-trains a QWEN-like model on `openwebtext-100k` dataset. We trained for one epoch and the resulting loss curve is compared against the Moonshot implementation to confirm behavioral consistency.

**Numerics**
We evaluate our implementation with existing implementation to confirm numerical consistency.

As discussed, our implementation closely follows the algorithm described in [Keller's post](https://kellerjordan.github.io/posts/muon/), while incorporating the learning rate adjustment from [Moonlight](https://github.com/MoonshotAI/Moonlight/blob/master/Moonlight.pdf). This captures a key insight that allows users to reuse hyper-parameters tuned for `adamW`, making Muon a drop-in swap.

As expected, the numerics difference mainly comes from `adjust_lr`, a max of ~5% relative diff in an example unit test setup below.

```python
    # dummy model and data
    model0 = Linear(10, 10, bias=False)
    model1 = copy.deepcopy(model0)
    inputs = torch.randn(8, 10)
    targets = torch.randn(8, 10)
    loss = MSELoss()

    lr = 1e-3
    wd = 0.1
    momentum = 0.95

    opt_ref_muon = KellySingleDeviceMuon(
        params=model0.parameters(),
        lr=lr,
        weight_decay=wd,
        momentum=momentum,
    )

    opt_exp_muon = Muon(
        params=model1.parameters(),
        lr=lr,
        weight_decay=wd,
        momentum=momentum,
    )

    out_ref = model0(inputs)
    loss_ref = loss(out_ref, targets)
    opt_ref_muon.zero_grad()
    loss_ref.backward()
    opt_ref_muon.step()

    out_exp = model1(inputs)
    loss_exp = loss(out_exp, targets)
    opt_exp_muon.zero_grad()
    loss_exp.backward()
    opt_exp_muon.step()

    for p_ref, p_exp in zip(model0.parameters(), model1.parameters()):
        torch.testing.assert_close(p_ref, p_exp)
```

As explained above, including this `adjust_lr` is preferable. This is validated by an e2e training runs on training a qwen-2-like 0.5b model, where the curves show that training with `adjust_lr` converges more effectively than without.

**Performance**
Training for one epoch of openwebtext-100k on eight H100 GPUs with DDP:

- adamw_ddp finishes in 13.12 min
- pytorch_muon_ddp finishes in 13.45 min

Muon runs ~20s slower compared to AdamW. Assuming no other changes, Muon is *2.5%* slower than AdamW.

AdamW: Optimizer.step() takes ~13.5 ms, step time ~930 ms

Muon: Optimizer.step() takes ~54 ms, step time ~960 ms

**Note**
We restrict the implementation to accept only 2D parameters.

An alternative approach is to allow parameters with more than two dimensions and apply orthogonalization over the last two dimensions. We opt not to go with this approach as it can be error-prone. For example, with a kernel shaped `[in_channel, height, width, out_channel]`, applying orthogonalization to the last two dimensions is not meaningful.

Since Muon is designed to operate orthogonalization on 2D matrices, preserving this assumption keeps the implementation clean and sound.

**Next Steps**

1. Add `MuP`
2. Open-source optimized triton kernel for symmetric matmul. A preliminary benchmark found 1.23x - 1.48x speedup on small - large (n = 256 -> 16384) matrices.
3. Open-source unsharded Muon co-designed with FSDP2.

+
+    Here, :math:`\mathrm{NS}^{(a,b,c)}_{k}(\cdot;\varepsilon)` denotes :math:`k` iterations of the
+    Newton–Schulz orthogonalization operator parameterized by coefficients :math:`(a,b,c)`
+    with numerical stabilization :math:`\varepsilon`.
+
+    The purpose for :math:`\mathrm{AdjustLR}\!\big(\gamma;\ \mathrm{shape}\!\big(\theta_t \big) \big)`
+    is to make the orthogonalized update have a consistent :math:`RMS` across rectangular matrices.
+
+    Keller's original implementation scales the update by :math:`\sqrt{\max\!\left(1, \frac{A}{B}\right)}`,
+    where :math:`A` and :math:`B` are dimension of the matrix being optimized.
+
+    Moonshot's implementation also focuses on matching :math:`RMS` of AdamW. The adjustment is computed as:
+    :math:`\gamma \leftarrow {0.2}\gamma\,\sqrt{\max\!\left({A}, {B}\right)}`
+    The method is adopted from `Muon is Scalable for LLM Training`_. Research
+    results show that with this adjustment Muon can directly reuse the learning rate
+    and weight decay tuned for AdamW.
+
+    We provide two options for the learning rate adjustment: "original", which follows Keller's
+    implementation, and "match_rms_adamw", which refers to Moonshot's implementation. This gives users the
+    flexibility to choose between the two. If `adjust_lr_fn` is not specified, the default is "original".
+
+    For further details regarding the algorithm we refer to `Muon: An optimizer for hidden layers in neural networks`_
+    and `Muon is Scalable for LLM Training`_.

Subject: [PATCH 0771/1424] [DTensor] Make default RNG semantics match
 user-passed generator (#160482)

Previously, DTensor kept its own copy of the generator state after the
first time a random operator was called on a DTensor. This copy would
evolve independently from the generator outside of DTensor.

After adding support for users to pass a specific generator into
random operators (e.g. `uniform_(..., generator=)`), it was determined
(in discussion on #159991) to change the semantics so that any random
operations performed on DTensor would evolve the state of the publicly
visible generators (either the default one or user-passed one).

The upsides are (1) it is now possible to call torch.manual_seed() at
any point in the program and have a consistent effect on DTensor, (2)
DTensor ops have an observable effect on the generator.  The downside is
that users are now responsible for seeding their generator before using
DTensor, ensuring all ranks use the same seed.

Fixes #159991

+### Random Operations
+
+DTensor provides distributed RNG functionality to ensure that random operations on sharded tensors get unique values, and random operations on replicated tensors get the same values. This system requires that all participating
+ranks (e.g. SPMD ranks) start out using the same generator state before each dtensor random operation is performed,
+and if this is true, it ensures they all end up at the same state after each dtensor random operation completes. There is no communication performed during random operations to synchronize RNG states.
+
+Operators that accept a `generator` kwarg will utilize the user-passed generator, if passed, or the default generator for the device otherwise. Whichever generator is used, it will be advanced after the DTensor operation.  It is valid to use the same generator for both DTensor and non-DTensor operations, but care must be taken to ensure the non-DTensor operations advance the generator state equally on all ranks if so.
+
+When using DTensor together with Pipeline Parallelism, ranks for each pipeline stage should use a distinct seed, and ranks within a pipeline stage should use the same seed.
+
+DTensor's RNG infra is based on the philox based RNG algorithm, and supports any philox based backend (cuda, and other cuda-like devices), but unfortunately does not yet support the CPU backend.

Subject: [PATCH 0772/1424] port distributed pipeline test files for Intel GPU
 (#159033)

In this PR we will port all distributed pipeline test files.
We could enable Intel GPU with following methods and try the best to keep the original code styles:

1. instantiate_device_type_tests()
2. use "torch.accelerator.current_accelerator()" to determine the accelerator backend
3. use "requires_accelerator_dist_backend()" to replace requires_nccl()
4. use "get_default_backend_for_device()" to get backend
5. enabled XPU for some test path

Pull Request resolved: https://github.com/pytorch/pytorch/pull/159033
Approved by: https://github.com/guangyey, https://github.com/kwen2501

Subject: [PATCH 0774/1424] xpu: fix cpp_extension compatibility with oneapi
 dpc++ 2025.2 compiler (#161012)

Intel oneapi DPC++ compiler has changed (fixed) parsing of `-fsycl-host-compiler-options` option in the respect of treating arguments with escaped quotes. This commit adds an if branches depending on compiler versions.

Fixes: https://github.com/intel/torch-xpu-ops/issues/1938

Subject: [PATCH 0781/1424] [dynamo] Refactor convert_frame.compile_frame to be
 self contained function. [5/n] (#160900)

convert_frame.compile_frame used to take a callback transform function which will capture the frame object it has, but the frame information is not passed directly into compile_frame function.

This PR changes the signature of compile_frame so that frame information is directly passed in the function without taking a callback. This makes it easier to build fullgraph capture API on top of compile_frame.

Subject: [PATCH 0788/1424] [aoti-fx] Output OpOverload fallbacks (#161195)

Updates the inductor-wrapper-fxir code to use the kernel.op_overload when generating extern kernel calls. This way we can keep the IR consistent with using ATen ops.

TODO: we're also inserting torch.empty_strided calls -- need to turn this into aten too

Subject: [PATCH 0790/1424] Fix OpSchema equality check (#161231)

`__eq__` didn't compare lists of DTensorSpec, but `__hash__` did (and
it looks like attention was paid to hash, so I made comparison follow
suit).

Subject: [PATCH 0791/1424] Use comparison key in OpSchema to avoid duplicate
 work between `__hash__` and `__eq__` (#161234)

The performance cost of `dict` lookups keyed by `OpSchema` is a
significant minority of DTensor overhead. With this change we shave a
net ~1% off the total running time of the benchmark from #160580, as
measured by using cProfile and comparing cumulative time spent in
propagate + OpSchema's `__post_init__`. (`__post_init__` grew from
2.5% to 6.4% (+3.9%) and propagate shrank from 12.5% to 7.8% (-4.7%)).

Subject: [PATCH 0796/1424] Revert "[dynamo] Refactor
 convert_frame.compile_frame to be self contained function. [5/n] (#160900)"

This reverts commit 1113e7de30da95973c1eac7921601f9a0e94f2db.

Reverted https://github.com/pytorch/pytorch/pull/160900 on behalf of https://github.com/atalman due to executorch failure ([comment](https://github.com/pytorch/pytorch/pull/160900#issuecomment-3221372096))

Subject: [PATCH 0797/1424] Fix the parity of original and exported module
 parameters (#160600)

## Problem
Fixing parameter mismatch issue during torch.export with strict mode (see "How to reproduce the issue" section below):

When there are two attribute mapping to the same tensor, the strict mode will
1. Have a standard param buffer table to standardize the name (bug happens [here](https://github.com/supercharleszhu/pytorch/blob/f861dc1826f7b49de37a5578d6e9ef6300498606/torch/export/_trace.py#L356)! when 2 parameter have same id(param), the latter name will overwrite the previous name)
2. [Update](https://github.com/supercharleszhu/pytorch/blob/f861dc1826f7b49de37a5578d6e9ef6300498606/torch/export/_trace.py#L1481) exported signature with updated standard FQN (problematic)
3. When getting exported_program.module(), it will call [_unlift_exported_program_lifted_states](https://github.com/supercharleszhu/pytorch/blob/f861dc1826f7b49de37a5578d6e9ef6300498606/torch/export/exported_program.py#L1297) to recover attribute from exported signature where the parameter name is defined and standardized
Then the named_parameter of this module will have overwritten name instead of original name

## How to reproduce the issue?
reproduce issue shared by @taotaohuang001

torch version: 2.8.0
```python
import torch
from torch import nn

# ---- Toy model with embedding weight sharing (aliasing) ----
class Toy(nn.Module):
    def __init__(self):
        super().__init__()
        self.embedding_layers = nn.ModuleDict()
        tbl = nn.Embedding(100, 8)
        self.embedding_layers["ActorId"] = tbl
        # Alias: reuse the SAME module instance for another feature
        self.embedding_layers["RootActorId"] = self.embedding_layers["ActorId"]
        self.proj = nn.Linear(16, 1)

    def forward(self, feats: dict[str, torch.Tensor]):
        e1 = self.embedding_layers["ActorId"](feats["ActorId"])
        e2 = self.embedding_layers["RootActorId"](feats["RootActorId"])
        return self.proj(torch.cat([e1, e2], dim=-1))

torch.manual_seed(0)

m = Toy().eval()

# Show pre-export parameter names (canonicalized; shared weight appears once)
print("PRE-EXPORT named_parameters:")
print([name for name, _ in m.named_parameters()])

# Sanity: the two feature names point to the same weight object
w1 = m.embedding_layers["ActorId"].weight
w2 = m.embedding_layers["RootActorId"].weight
print("PRE-EXPORT alias -> same object:", w1 is w2, "| same storage:", w1.data_ptr() == w2.data_ptr())

# Example inputs (dict structure will be captured by export)
ex_in = {
    "ActorId":     torch.randint(0, 100, (4,)),
    "RootActorId": torch.randint(0, 100, (4,)),
}

# ---- Export (in memory) and materialize the runnable module ----
ep = torch.export.export(m, (ex_in,), strict=True)
gm = ep.module()  # GraphModule with new (canonical) parameter names

print("\nPOST-EXPORT named_parameters (GraphModule):")
post_names = [name for name, _ in gm.named_parameters()]
print(post_names)

# Prove alias persists after export: run fwd/bwd and check a single grad tensor exists
out = gm(ex_in).sum()
out.backward()

# Find the embedding weight in the exported module by shape (100, 8)
emb_names = [name for name, p in gm.named_parameters() if p.shape == torch.Size([100, 8])]
print("\nEmbedding param (post-export) canonical name:", emb_names[0] if emb_names else "<not found>")

# Show that only one grad exists for the shared table
for name, p in gm.named_parameters():
    if p.grad is not None and p.shape == torch.Size([100, 8]):
        print("Grad present on shared embedding weight:", name, "| grad shape:", tuple(p.grad.shape))
        break

```

And you will see parameters are different before and after export
```
PRE-EXPORT named_parameters:
['embedding_layers.ActorId.weight', 'proj.weight', 'proj.bias']
PRE-EXPORT alias -> same object: True | same storage: True

POST-EXPORT named_parameters (GraphModule):
['embedding_layers.RootActorId.weight', 'proj.weight', 'proj.bias']

Embedding param (post-export) canonical name: embedding_layers.RootActorId.weight
Grad present on shared embedding weight: embedding_layers.RootActorId.weight | grad shape: (100, 8)

```
## Solution
Fixing this issue by making sure latter named parameter will not overwrite the `param_buffer_table` when original model's named parameter already maps to certain parameter.

Subject: [PATCH 0799/1424] [CUDAGraph] Add getter for cuda graph exec
 (#161294)

This is far simpler than #155164 since we never destroy the cudaGraphExec_t.

The request comes from TRT-LLM specifically. The motivation is that some power users would like to mutate specific kernel parameters via APIs like `cudaGraphExec*SetParams` after a cuda graph has been instantiated. For example, a common request has been to be able to change the sequence length of attention kernels, after having captured a graph for the largest possible sequence length. It turns out that the host overhead you eliminate via cuda graphs in LLM inference ends up causing an increase in computation time when you size your kernels to the maximum possible sequence length (which I believe is done in both TRT-LLM and vLLM). Attention is the most problematic kernel because its computation time is quadratic in the sequence length, rather than linear.

This can work if your attention kernel can work for arbitrary shapes (this is not the case for all attention implementations! Many of them specialize with templates), and you have a persistent kernel that allocates only as many blocks as you have SM's (so you don't have to figure out how many blocks to allocate for a specific sequence length). Using a conditional SWITCH node is a better generic approach to this problem, but that requires more infrastructure work.

Note that this requires knowledge of the exact location of the value in your kernel's parameter buffer to mutate. It won't work with arbitrary stream capture code whose kernels you don't know before hand. So I expect this code path to be rarely used.

Testing:

```
pytest -s -k raw_graph_exec test/test_cuda.py
```

Subject: [PATCH 0800/1424] Always run OIDC auth on B200 to be able to upload
 artifacts to S3 (#161436)

Reported by @drisspg , in its current form, the OIDC auth step wasn't run when the previous test step failed.  We need this to always run to be able to upload artifacts to S3.

Subject: [PATCH 0806/1424] [Inductor] Prune configs that require more shared
 memory than the hardware limit (#161040)

Summary:
This diff removes configs that require more shared memory than the hardware limit, which causes the following compilation error:
```
No valid triton configs. OutOfMemoryError: out of resource: triton_mm Required: 327680 Hardware limit:232448 Reducing block sizes or `num_stages` may help.
```

Test Plan:
```
buck2 test mode/dev-nosan fbcode//caffe2/test/inductor:max_autotune -- test_max_autotune_prune_choices -v 1,stderr
```

Rollback Plan:

Differential Revision: D80594562

Subject: [PATCH 0807/1424] [dynamo] Refactor convert_frame.compile_frame to be
 self contained function. [5/n] (#160900)

convert_frame.compile_frame used to take a callback transform function which will capture the frame object it has, but the frame information is not passed directly into compile_frame function.

This PR changes the signature of compile_frame so that frame information is directly passed in the function without taking a callback. This makes it easier to build fullgraph capture API on top of compile_frame.

Subject: [PATCH 0810/1424] [pytorch] Leverage `unordered_map.try_emplace()` to
 simplify code (#161388)

Summary: Because [`unordered_map.try_emplace()`](https://en.cppreference.com/w/cpp/container/unordered_map/try_emplace.html) does not invoke value's constructor if key is already existed, this matches with the previous the behavior on checking the key's existence first, and then instantiate the value.

Subject: [PATCH 0811/1424] Increase timeout value when pushing to ghcr.io
 (#161444)

Seeing this timing out a lots in trunk now https://github.com/pytorch/pytorch/actions/runs/17165552358/job/48705069047.  The benchmark image is the largest one we have on CI, so it's probably over the 30 minutes limit.

Subject: [PATCH 0812/1424] [Inductor][Triton] Fix SCALING_ROWWISE
 misclassification for scalar scales (#160450)

Summary: In `tuned_scaled_mm()`, we unsqeeuze any scalar scale from [] -> [1, 1]. Later, when we are determining how to set the `SCALING_ROWWISE` kernel attribute, we check whether the scale has 2 dimensions. However, since we previously unsqueezed any scalar scales, this will always evaluate to True.

Test Plan:
Run the following tests in test/inductor/test_fp8.py:
test_tensorwise_scaling_tma_template
test_rowwise_scaling_tma_template

Rollback Plan:

The comments/conventions are not exactly correct here, as the implementation at this PR is partial. They will be fixed in #160138.

No tests added, since there shouldn't be any overall semantic changes.

Subject: [PATCH 0817/1424] [dynamo, nested graph breaks] support very simple
 nested graph breaks (#159329)

e.g. this graph breaks once now:
```python
import torch

torch._dynamo.config.nested_graph_breaks = True

def inner(x):
    x = x + 1
    torch._dynamo.graph_break()
    return x + 2

@torch.compile(backend="eager")
def outer(x):
    return inner(x)

print(outer(torch.ones(3)))
```

Subject: [PATCH 0820/1424] [dynamo, nested graph breaks] clean up comments and
 codegen (#160138)

Fix comments to reflect that we no longer codegen cells to be sent to resume function as inputs - they are instead codegen'd after the unsupported instruction in order to build resume functions that are closures.

Also simplify some codegen.

Subject: [PATCH 0821/1424] [dynamo, nested graph breaks] prevent excessive
 recompilations (#159786)

Nested continuation function code objects are now unique w.r.t. stack trace below (and including) the current code object.

Without this change, e.g. in the added test, `f3` would be recompiled on the second graph break.

Followup: we can skip guards on continuation functions.

Subject: [PATCH 0822/1424] [1/n][export] Refactor PT2 Archive weight saving
 and loading (#160394)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:

We split the refactoring in two parts for forward compatibility concerns
First, we land the deserialization (loading part)
Then, we land the serialization (saving part)

Save weights and constants as individual files in PT2 archive. Each weight/constant will be saved as raw bytes, unless it is a custom object (TorchBind object) or a non-fake tensor subclass, for these two special cases we still save them using pickle.

The metadata of saved tensors along with the file name will be saved as `PayloadMeta`.
The mapping from FQN to `PayloadMeta` will be saved as `PayloadConfig` under `WEIGHTS_CONFIG_FORMAT` and `CONTANTS_CONFIG_FORMAT`

This changes the serialization in python side when calling `torch.export.save()`.

For deserialization in python `torch.export.load()`, we make it BC-safe by allowing loading legacy format weights/constants.

For deserialization in C++ `torch/nativert/ModelRunner.cpp`, we make this a BC breaking change as currently the OSS ModelRunner API is not being used.

Subject: [PATCH 0823/1424] Update pybind11 submodule to 3.0.1 (#160754)

Upgrade to PyBind11 v3. This allows us to strip out our own (possibly broken?) handling of the C++ ABI when building extensions, in favor of the more-complete PyBind11 internal handling.

Fixes a few test failures due to https://github.com/pybind/pybind11/issues/5774, which effectively makes the `__qualname__` attribute of functions platform-dependent.

Test plan: CI

Pull Request resolved: https://github.com/pytorch/pytorch/pull/160754

Subject: [PATCH 0825/1424] Disable inductor/test_flex_attention.py (#161450)

Currently inductor/test_flex_attention.py is causing rocm pytorch mi250 shard 1 to go over the timeout limit. This PR is for disabling that test.

Subject: [PATCH 0828/1424] Increase timeout value when pushing to ghcr.io
 (#161444)

Seeing this timing out a lots in trunk now https://github.com/pytorch/pytorch/actions/runs/17165552358/job/48705069047.  The benchmark image is the largest one we have on CI, so it's probably over the 30 minutes limit.

Subject: [PATCH 0834/1424] [Inductor][Tritonparse] Call
 `jit_post_compile_hook` within Inductor Triton Kernel compile path (#161443)

Summary: Since Inductor skips JIT compilation for Triton kernels, we need to manually invoke `knobs.runtime.jit_post_compile_hook` if one exists. Here, we do this to enable Tritonparse to extract launch metadata from Inductor launched kernels. We can control whether or not Inductor will run the hook with a new `TORCHINDUCTOR_RUN_JIT_POST_COMPILE_HOOK=1 ` config variable.

A performance optimization. Using `torch.addmm`, which fuses `matrix multiply + scale + add` into one op.

**Benchmark**
In a QWEN-like 0.5B model training we observed average `optimizer.step()` latency speedup: matmul ~44.5 ms -> addmm ~27.4 ms: a **1.62×** speedup.

**Testing**
End-to-end training:
We used a training script that pre-trains a QWEN-like model on `openwebtext-100k` dataset. We trained for one epoch and the resulting loss curves show consistency between normal matmul and addmm.

Unit test:

```python
    # dummy model and data
    model0 = Linear(10, 10, bias=False)
    model1 = copy.deepcopy(model0)
    inputs = torch.randn(8, 10)
    targets = torch.randn(8, 10)
    loss = MSELoss()

    lr = 1e-3
    wd = 0.1
    momentum = 0.95

    opt_ref_muon = Muon(
        params=model0.parameters(),
        lr=lr,
        weight_decay=wd,
        momentum=momentum,
        nesterov=nesterov,
        adjust_lr_fn="original",
    )

    opt_exp_muon = Muon(
        params=model1.parameters(),
        lr=lr,
        weight_decay=wd,
        momentum=momentum,
        nesterov=nesterov,
        adjust_lr_fn="original",
        use_addmm=True,
    )

    out_ref = model0(inputs)
    loss_ref = loss(out_ref, targets)
    opt_ref_muon.zero_grad()
    loss_ref.backward()
    opt_ref_muon.step()

    out_exp = model1(inputs)
    loss_exp = loss(out_exp, targets)
    opt_exp_muon.zero_grad()
    loss_exp.backward()
    opt_exp_muon.step()

    for p_ref, p_exp in zip(model0.parameters(), model1.parameters()):
        torch.testing.assert_close(p_ref, p_exp)
```

shows numeric difference, but this is expected on bf16 precision:
```
Mismatched elements: 96 / 100 (96.0%)
Greatest absolute difference: 8.985400199890137e-05 at index (1, 9) (up to 1e-06 allowed)
Greatest relative difference: 0.007370449136942625 at index (0, 6) (up to 1e-05 allowed)
```

~~Introduced a flag that allows users to opt in, as there are numerical differences relative to the original implementation.~~
Update: since `addmm` fuses the math ops, there are fewer intermediate roundings and is therefore more numerically accurate compared to the original form. Based on this, we opt to make `addmm` the default and only option.

Subject: [PATCH 0839/1424] [easy][test] Add repeat_interleave opinfo that
 exercises binary search fusion (#161445)

This adds a configuration that would have caught the need for https://github.com/pytorch/pytorch/pull/159961 when https://github.com/pytorch/pytorch/pull/158462 was landed.

Notably:
* the test has output_size kwarg specified
* the input is 1D plus a size-1 dimension (otherwise, if there are non-size-1 dimensions, then the fusion won't occur)

Subject: [PATCH 0840/1424] Revert "[dynamo] Refactor
 convert_frame.compile_frame to be self contained function. [5/n] (#160900)"

This reverts commit 447d34b5f80fb7350f79decd855cb599cab39083.

Reverted https://github.com/pytorch/pytorch/pull/160900 on behalf of https://github.com/atalman due to reverting since can't land existing diff internally, will need to reland it ([comment](https://github.com/pytorch/pytorch/pull/160900#issuecomment-3224029031))

Subject: [PATCH 0841/1424] Update NVSHMEM to 3.3.24 and fix download link
 (#161321)

https://github.com/pytorch/pytorch/issues/159779

Update NVSHMEM 3.3.24 for [PyTorch CUDA13 Binary Cannot Be Built with SM_75 with NVSHMEM](https://github.com/pytorch/pytorch/issues/160980)
Enabled back sm_75 for NVSHMEM
Fixed the NVSHMEM download link for the issue with 3.3.20 download in issue - [[CD] nvshem-3.3.9 wheels for aarch64 is not manylinux2_28 compliant](https://github.com/pytorch/pytorch/issues/160425)

Todo: Should also enable back build ARM with NVSHMEM since it is compatible with manylinux2_28

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161321
Approved by: https://github.com/Skylion007, https://github.com/atalman

Subject: [PATCH 0844/1424] [ez][CI] GIve the linux check job a name that isn't
 linux-job (#161413)

Reason:
The default name is linux-job, which gets put in the linux category on HUD, but this isn't really a linux related job.  Renaming it like this will make it go into the "other" category on HUD

Other options:
Change the grouping code in test-infra

Subject: [PATCH 0847/1424] [dynamo] lift backed symint output of item()
 (#161198)

Before the change in this PR, we have an error for the following code
```python
import torch

torch._dynamo.config.capture_scalar_outputs = True

class M(torch.nn.Module):
    def forward(self, idx, x):
        u0 = idx.item()
        x0 = x.select(0, u0)
        def fn():
            return x0.sin()
        return torch.cond(x0.sum() > 0, fn, fn)

m = M()
out = torch.compile(m, fullgraph=True)(torch.tensor(0, dtype=torch.int64), torch.randn(3, 3))
```

The error is caused when speculate fn, and tries to lift symbol of x0.storage_offset() but found the symbols doesn't have a source associated with it.

What really happens is that, when input tensor is a scalar tensor of int type and resides on CPU, we have a short cut that creates a norm symint when .item() is called see https://github.com/pytorch/pytorch/pull/126245.

However, previously, we only track the unbacked symint output of an operation because we believe all the backed symint must have a source associated with it and has already bee lifted as input at the top-level. Now this invariant no longer holds, so we end up an error saying the symbol doesn't have source (because only input and symbols derided from inputs have source and result of .item() doesn't have a source).

In this PR, we start to also track the normal symint with the proxy that created it (i.e. in this case the proxy .item()).

Subject: [PATCH 0848/1424] [dynamo] auto lift unbacked symbol in tensor's
 storage_offset (#161199)

```python
import torch

torch._dynamo.config.capture_scalar_outputs = True

class M(torch.nn.Module):
    def forward(self, idx, x):
        u0 = idx.item()
        x0 = x.select(0, u0)
        def fn():
            return x0.sin()
        return torch.cond(x0.sum() > 0, fn, fn)

m = M()
out = torch.compile(m, fullgraph=True)(torch.tensor(0, dtype=torch.int64, device="cuda"), torch.randn(3, 3, device="cuda"))
print(out)

```

Before the PR, we didn't track the storage_offset symbol of a tensor. After https://github.com/pytorch/pytorch/pull/157605, we create an unbacked_symint for stroage_offset for the result of select. So when we try to lift the free basic symbols of x0  during speculating fn, we found a free symbol that's not bound to a proxy.

This PR tracks the symbols of storage_offset and associated it with a proxy using torch.ops.aten.storage_offest.

Subject: [PATCH 0852/1424] [dtensor] Add propagate_tensor_meta function that
 skips cache if _are_we_tracing (#161334)

Fixes an issue where the log softmax handler checked the tensor metadata cache without checking for tracing or symints.

Probably best to merge this after #160798, but not strictly blocking.

Subject: [PATCH 0855/1424] [reland] [dynamo] Refactor
 convert_frame.compile_frame to be self contained function. [5/n] (#161514)

Summary:
convert_frame.compile_frame used to take a callback transform function which will capture the frame object it has, but the frame information is not passed directly into compile_frame function.

This PR changes the signature of compile_frame so that frame information is directly passed in the function without taking a callback. This makes it easier to build fullgraph capture API on top of compile_frame.

CI

Subject: [PATCH 0857/1424] Add inductor backend to device interface; make
 minifier_tests more device agnostic (#151314)

Tried to decouple the always cpu <=> c++, cuda <=> triton assumption. Tried to keep it relatively simple by just guarding things more specifically, at the moment.

Subject: [PATCH 0859/1424] Revert "[dynamo, nested graph breaks] clean up
 comments and codegen (#160138)"

This reverts commit ac6316caaa74513cbcf3c7f9269bc23cd74749db.

Reverted https://github.com/pytorch/pytorch/pull/160138 on behalf of https://github.com/atalman due to failing internal tests ([comment](https://github.com/pytorch/pytorch/pull/160138#issuecomment-3225546707))

Subject: [PATCH 0866/1424] [ROCm] No-fence global reduce (#161180)

This change removes need for fences in global_reduce by converting the stores to reduce_buffer[] into atomics+return. This is crucial for perf in architectures with split caches (e.g. MI300), where fences are inherently costly.

Subject: [PATCH 0869/1424] [ONNX] Drop draft_export in exporter API (#161454)

If onnx exporter fallbacks to draft_export with big models, this is taking forever for users, and possibly spam the printout, which keeps users from their stack trace with strict=False.

We could consider make another API for draft_export as debugging tool, or combine it with report=True when "model is small"?

Subject: [PATCH 0871/1424] Add early_stop kwarg to torch.utils.checkpoint
 (#160781)

We already have a context manager "set_checkpoint_early_stop". This PR adds a kwarg that toggles the same setting.

It is also useful to have a kwarg version of the setting in addition to the context manager because is annoying to apply a context manager when the AC is being applied via CheckpointWrapper.

Similar to the "debug" kwarg and the corresponding "set_checkpoint_debug_enabled" context manager, the context manager defaults to None and overrides the local setting when non-None.

Subject: [PATCH 0872/1424] [Inductor] Add DeviceAssert op to enable
 device-side assertion in torch.compile (#160677)

This PR introduces a device_assert op to trigger device-side assertions within torch.compile. This implementation is based on the suggestion in [this comment](https://github.com/pytorch/pytorch/issues/147282#issuecomment-2756056084).

Changes Included

- Implemented device_assert op and overrides has_side_effect to return True to avoid removal by dead code elimination.
- Commented out the assert_async_msg_decomp and functional_assert_async_msg_decomp decompositions to disable the default assert decomposition inside Inductor.
- Added lowering for torch.ops.aten._assert_async.msg to convert assert calls into the ops_handler.
- Implemented the codegen method for the device_assert op. This supports generating C++ and Triton code.
- Added test cases to verify both "should throw" and "should not throw" scenarios.

Fixes #147282

Subject: [PATCH 0876/1424] [APS IR] Minfor fix - use GetAttrKey in get_keystr
 to match with flat args path in unflatten (#161453)

Summary: While passing path info to [_check_input_constraints_for_graph](https://www.internalfb.com/code/fbsource/[6b5b2dc35902a26ce265e3c0ae5189a3faba1d38]/fbcode/caffe2/torch/export/unflatten.py?lines=594), GetAttrKey is used to specify path str. To match with that get_keystr should also use GetAttrKey.

Test Plan:
Existing tests

```
buck run mode/opt caffe2/test:test_export -- -r unflatten

Subject: [PATCH 0877/1424] [Inductor-FX] Support custom triton kernels
 (#161474)

# Feature
Add support for custom Triton kernels to the FX backend. This turned out not to require any new features, except for a minor change to handle `tl.constexpr` arguments which are not part of the autotuning config.

# Caveat

This may not cover every possible case. For example, we might need more features for autotuning custom Triton code. This PR entirely skips the [custom codegen ](https://github.com/pytorch/pytorch/blob/main/torch/_higher_order_ops/triton_kernel_wrap.py#L1034-L1039) for user-defined grid functions, but there may be edge cases requiring this logic. However, this PR seems to do a reasonable job as many of the grids end up being written into Inductor/Triton metadata and don't require special codegen.

As a follow up, I'm planning to test this against all of AOTI's custom Triton kernel tests.

# Test plan
Added a CI test using a custom Triton kernel.

Subject: [PATCH 0881/1424] [1/N][SymmMem] Add offset to handle, cache on base
 address (#161470)

For the kernels that need peer pointers directly, the rendezvous handle should allow user to get the offset of tensor wrt to base allocation address. Thus the need to add an `offset` field to SymmMem handle.

But we don't want to cache all the handles just bc they have different offsets, hence the search and cache logic below:

(i) At rendezvous, the search key is still `x.storage().data_ptr()`, like now, but it should do search in 2 parts - one is just dictionary lookup, like today, if that failed, it needs to search `allocations_` to see if the storage ptr falls in one of the segments. This is possible as we have all segments recorded during alloc.
(ii) If this segment hasn't been rendezvoused, we rendezvous it, cache it in the `symm_mem_` map with its base address as key.
(iii) We still need to return a handle for the current tensor, with a corresponding offset. This handle will be a shallow copy of the base handle, with the offset adjusted.

Some impl details:
(i.1) If we find a matching allocation, we can immediately use the allocation base address to do a re-search in `symm_mem_`.

(iii.1) To make the handle copy shallow, we move the common information -- base ptrs, base signal pad, etc -- to a structure referenced by both handles. The structure is called `NVSHMEMPeerAllocInfo`. A copy of handle just adds one more `intrusive_ptr` to it. The handle copy constructor accepts an `offset` argument.

Test:
Existing tests should not fail.

Subject: [PATCH 0882/1424] [2/N][SymmMem] Add MemPool allocator and tests
 (#161471)

(Porting most of #161008)

Hooking SymmetricMemory Allocator to MemPool so that user can create symmetric tensors with regular `torch.zeros`, `torch.arange` etc factories. Also so that our ops can have functional variants that create `out` tensors on symmetric memory.

To end users, this PR supports a python UI as follows:
```
allocator = symm_mem.get_mempool_allocator(device)
mempool = torch.cuda.MemPool(allocator)
with torch.cuda.use_mem_pool(mempool):
    tensor = torch.arange(numel, dtype=dtype, device=device)
```

Added tests for both use cases above.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161471
Approved by: https://github.com/ngimel

Subject: [PATCH 0888/1424] [dynamo, nested graph breaks] add nested graph
 break tests (#144516)

Note: nested graph break tests (and wrapped tests) are xfailed/skipped for now - we will iteratively enable the tests as more of the nested graph break implementation is complete.

Subject: [PATCH 0892/1424] Add debug handle to inductor provenance tracking
 (#161110)

Summary:
Use debug handle on kernel names to distinguish different calls to the same kernel.

Previous kernel name: kernel_name

New kernel name: kernel_name:debug_handle

We add the debug handle to the tlparse artifacts: `inductor_provenance_tracking_node_mappings` and `inductor_provenance_tracking_kernel_stack_traces`.

We also add debug handles in the comments of the generated code so we can map to them in the provenance tracking highlighter tool: https://github.com/pytorch/tlparse/pull/134

Example output code is below. If a kernel doesn't have a debug handle, the `[Provenance debug handles]` comment line will not be written.

```
        # Topologically Sorted Source Nodes: [y, z], Original ATen: [aten.addmm, aten.gelu]
        # [Provenance debug handles] triton_poi_fused_addmm_gelu_2:3
        stream0 = get_raw_stream(0)
        triton_poi_fused_addmm_gelu_2.run(buf4, primals_5, 300, stream=stream0)
```

The debug handles will also be used by downstream profilers such as zoomer.

Test Plan:
```
buck run mode/opt fbcode//caffe2/test/inductor:provenance_tracing
```

Rollback Plan:

Subject: [PATCH 0894/1424] [CD] [aarch64] Add CUDA 13.0 sbsa nightly build
 (#161257)

https://github.com/pytorch/pytorch/issues/159779

CUDA SBSA build for CUDA 13.0
1. Supported archs: sm_80 to sm_120. Including support for Thor (sm_110), SPARK (sm_121), GB300 (sm_103).
"This release adds support of SM110 GPUs for arm64-sbsa on Linux." from 13.0 release notes https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html
2. Use -compress-mode=size for binary size reduction, 13.0 wheel is 2.18 GB, when compared with 12.9 3.28 GB, that is 1.1 GB of savings and ~33.5% smaller.
3. Refactored the libs_to_copy list with common libs, and version_specific_libs.

TODO: add the other CUDA archs in the existing support matrix of x86 to SBSA build as well

Subject: [PATCH 0896/1424] [OpenReg] Add Develop Notes for Integrating New
 Backend into PyTorch (#158644)

To facilitate the integration of the new backend, we plan to publish a new development note that details all the key components,hoping to speed up the development of other accelerators.

This PR is the beginning of this note, and involve the part of registration of operators and we will gradually improve it and keep in sync with OpenReg's code.

+# Extending PyTorch with New Accelerators
+
+## Background
+
+Since PyTorch 2.1, the community has made significant progress in simplifying the integration of new accelerators into the PyTorch ecosystem. These improvements include, but are not limited to: refinement of the `PrivateUse1` Dispatch Key, introduction and improvement of core subsystem extension mechanisms, and device-agnostic refactoring of key modules (e.g., `torch.accelerator`, `memory management`). Taken together, these improvements lay the foundation for a **robust**, **flexible** and developer-friendly accelerator integration path.
+
+### Why Does This Matter?
+
+This integration path has several key advantages:
+
+* **Speed**: Extensibility is built-in for all core PyTorch modules. Developers can integrate new accelerators into their downstream codebase independently without modifying upstream code and without being constrained by community review bandwidth.
+* **Future-proofing**: This integration path is the default for all future PyTorch features, which means that new modules and features will automatically support scaling to new accelerators as long as this path is followed.
+* **Autonomy**: Vendors have full control over their accelerator integration timelines, enabling agile iteration cycles and reducing reliance on upstream coordination.
+
+### About This Document
+
+This guide aims to provide a **comprehensive overview of the modern integration pathway** for new accelerator in PyTorch. It walks through the full integration surface, from low-level device primitives to higher-level domain modules like compilation and quantization. The structure follows a **modular and scenario-driven approach**, where each topic is paired with corresponding code examples from [torch_openreg][OpenReg URL], an official reference implementation.
+
+The goal is to help developers:
+
+* Understand the full scope of accelerator integration;
+* Follow best practices to quickly launch new accelerators;
+* Avoid common pitfalls through clear, targeted examples.
+
+### Target Audience
+
+This document is intended for:
+
+* **Accelerator Developers** who are integrating accelerator into PyTorch;
+* **Advanced PyTorch Users** interested in the inner workings of key modules;
+
+Next, we will officially embark on the integration journey of the new PyTorch accelerator.
+
+## Operators
+
+For new accelerators, one of the most important and fundamental aspects of integration is supporting high-performance operators. To facilitate operator adaptation for users and accelerator developers, PyTorch provides multiple methods for developing and registering operators in both `Python` and `C++`. The following sections detail some of PyTorch's fundamental capabilities for operator registration.
+
+```{note}
+`Dispatch Key` is used to uniquely identify accelerator within PyTorch, such as `CPU`, `CUDA`, `MPS`, and `PrivateUse1`. In theory, all subsequent new accelerators will share `PrivateUse1`, leveraging its built-in comprehensive scaffolding capabilities to complete the integration of new accelerators. Please refer to [Let's talk about the PyTorch dispatcher](https://blog.ezyang.com/2020/09/lets-talk-about-the-pytorch-dispatcher/) if you are interested with dispatcher.
+```
+
+(operator-set)=
+
+### Operator Set
+
+PyTorch currently has over 3500 built-in operators (including related operator variants). This represents a significant workload from any perspective, and supporting this massive number of operators in a short period of time is no easy task. Therefore, as the first step in developing new backend operators, our goal should be to focus on the essential operators. For other operators, we can first use the community's fallback mechanism to support the feature as the first priority. After that, we can gradually complete other operators to improve the performance of the new backend.
+
+The required operator set is listed below, primarily consisting of low-level operators required by factory functions and fallback operators:
+
+| Operator Name                      | Dispatch Key | Description                                                                                                        |

+
+### Basics
+
+Now that we have defined the initial scope of operator support, we can begin developing operator adaptations. This section will explain these implementations in `Python` and `C++` based on actual scenarios.
+
+(step-one)=
+
+#### Step 1
+
+{ref}`The operators mentioned above <operator-set>` share a common characteristic: They are built-in PyTorch operators with defined `namespaces` and `Schemas`, and these operators' built-in accelerators (`CPU`, `CUDA`, etc.) have been implemented. What we have to do next is to implement these operators for the new accelerators.
+
+::::{tab-set}
+
+:::{tab-item} C++
+
+```{eval-rst}
+.. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/native/Minimal.cpp

+    :end-before: LITERALINCLUDE END: EMPTY.MEMORY_FORMAT WRAPPER
+    :linenos:
+```
+
+:::
+
+::::
+
+Taking the `empty.memory_format` operator as an example, we first need to query the operator's `schema` information in `native_functions.yaml`, which contains detailed signature information. Then, we can implement the operator based on the capabilities of the new accelerator.
+
+```Yaml
+- func: empty.memory_format(SymInt[] size, *, ScalarType? dtype=None, Layout? layout=None, Device? device=None, bool? pin_memory=None, MemoryFormat? memory_format=None) -> Tensor
+dispatch:
+    CPU: empty_cpu
+    CUDA: empty_cuda
+    ...
+```
+
+::::{tab-set-code}
+
+```{eval-rst}

+    :end-before:  LITERALINCLUDE END: TORCH_LIBRARY_IMPL DEFAULT
+    :emphasize-lines: 1,2
+    :linenos:
+```
+
+::::
+
+After completing the `wrapper_empty_memory_format`, we can register `aten::empty.memory_format` for `PrivateUse1` through `TORCH_LIBRARY_IMPL`.
+
+#### Step 2
+
+By following {ref}`Step 1<step-one>`, we can complete the development and registration of all operators except `fallback`. Next, to support operators related to operations (such as mathematical operations and convolution operations), we need to implement the registration of fallback semantics. This is a built-in capability provided by the PyTorch framework that can fallback some operations that are not supported by new accelerators to the CPU for execution. For new backends in development, this is an extremely effective way to ensure functionality at the expense of performance.
+
+::::{tab-set}
+
+:::{tab-item} C++
+
+```{eval-rst}
+.. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/native/Minimal.cpp
+    :language: c++
+    :start-after: LITERALINCLUDE START: FALLBACK IMPL

+    :end-before: LITERALINCLUDE END: FALLBACK GLOBAL
+    :linenos:
+```
+
+:::
+
+::::
+
+`wrapper_cpu_fallback` wraps the `at::native::cpu_fallback` method provided by PyTorch and is registered with `PrivateUse1` in PyTorch via `TORCH_LIBRARY_IMPL`. Subsequent operations not supported by the new backend will automatically fall back to the CPU for execution, and the results will be passed back to the new backend after execution.
+
+### Advanced
+
+#### Selective Fallback
+
+Enabling the fallback mechanism only for certain operators, while following PyTorch's default behavior for other operators (an error will be reported if the accelerator does not have a corresponding operator implementation), this is a very reasonable scenario as well.
+
+::::{tab-set}
+
+:::{tab-item} C++
+
+```{eval-rst}
+.. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/OpenRegMinimal.cpp
+    :language: c++
+    :start-after: LITERALINCLUDE START: FALLBACK WRAPPER

+    :language: c++
+    :start-after: LITERALINCLUDE START: FALLBACK SINGLE
+    :end-before: LITERALINCLUDE END: FALLBACK SINGLE
+    :linenos:
+```
+
+:::
+
+::::
+
+Per-operator fallbacks are very similar to global fallbacks, the only difference being the registration method: calling `m.impl` registers an implementation for a specific operator, while `m.fallback` registers a default implementation for all operators.
+
+::::{tab-set-code}
+
+```{eval-rst}
+.. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/native/Minimal.cpp
+    :language: c++
+    :start-after: LITERALINCLUDE START: FALLBACK IMPL
+    :end-before: LITERALINCLUDE END: FALLBACK IMPL
+    :emphasize-lines: 2-5
+    :linenos:
+```
+
+::::
+
+Of course, global fallbacks can also be combined with a blacklist of fallbacks, which is a common approach, especially when only a few operators do not support fallbacks.
+
+#### PyTorch STUB
+
+PyTorch also provides another approach for built-in operators: `STUB`. This method is essentially based on the `Step 1<step-one>` approach, but adds secondary scheduling capabilities (for example, scheduling based on CPU characteristics).
+
+```{note}
+The `STUB` method currently supports only a limited set of operators. For new accelerator devices, the advantage of the `STUB` method is that it significantly reduces the cost of development at the cost of a small performance overhead. PyTorch currently does not clearly list the set of operators that can be registered through `STUB`. Due to the large number of related operators, only the query method for the supported operator list is provided here.
+```
+
+```shell
+pushd ${TORCH_ROOT}
+
+find aten -type f -a -name "*.h" | xargs -I {} grep -wl "^DECLARE_DISPATCH" {}
+
+popd
+```
+
+`DECLARE_DISPATCH` is a macro used to explicitly declare `STUB`. It is currently distributed in the `aten` directory. Based on this macro, you can find all operators that can be integrated using the `STUB` method.
+
+```text
+...
+aten/src/ATen/native/Activation.h
+aten/src/ATen/native/FusedSGD.h
+aten/src/ATen/native/nested/NestedTensorBinaryOps.h
+aten/src/ATen/native/TensorCompare.h
+aten/src/ATen/native/Sorting.h
+...
+```
+
+```c++
+using unary_fn = void(*)(TensorIteratorBase&);
+
+DECLARE_DISPATCH(unary_fn, abs_stub)
+```
+
+The above listing contains the file that declares the `STUB` operator, where you can clearly see the STUB name and the associated function signature. Next, we will take `abs_stub` as an example to briefly introduce the path to support operators through `STUB`.
+
+::::{tab-set}
+
+:::{tab-item} C++
+
+```{eval-rst}
+.. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/native/Extra.cpp
+    :language: c++
+    :start-after: LITERALINCLUDE START: STUB ABS
+    :end-before: LITERALINCLUDE END: STUB ABS
+    :linenos:
+```
+
+```{eval-rst}
+.. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/OpenRegExtra.cpp
+    :language: c++
+    :start-after: LITERALINCLUDE START: STUB DEFAULT
+    :end-before: LITERALINCLUDE END: STUB DEFAULT
+    :emphasize-lines: 1
+    :linenos:
+```
+
+:::
+
+::::
+
+From the signature, we can see that the input of `abs_stub` is `TensorIteratorBase`, a powerful helper class provided by PyTorch that contains all input and output operators, as well as some other auxiliary methods. Based on it, we can develop the `abs_kernel` operator and then call `REGISTER_PRIVATEUSE1_DISPATCH` to specify `abs_stub` to complete the registration.
+
+#### Custom Operators
+
+In addition to PyTorch's built-in operators, custom accelerator operators are also very common to improve performance in specific scenarios. These can be categorized into three main approaches:
+
+* Forward-only
+* Forward and backward: Separate registration
+* Forward and backward: Implemented using `torch.autograd.Function`
+
+```{note}
+There are more details in PyTorch tutorials, so refer to [PyTorch Custom Operators](https://docs.pytorch.org/tutorials/advanced/custom_ops_landing_page.html) if you are interested.
+```
+
+Here, we'll briefly introduce the implementation process of custom operators, focusing on the forward-only approach. The implementation can be summarized into the following three points:
+
+1. **Define Schema:**
+
+    ::::{tab-set}
+
+    :::{tab-item} C++
+
+    ```{eval-rst}
+    .. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/OpenRegExtra.cpp
+        :language: c++
+        :start-after: LITERALINCLUDE START: CUSTOM OPERATOR SCHEMA
+        :end-before: LITERALINCLUDE END: CUSTOM OPERATOR SCHEMA
+        :emphasize-lines: 2
+        :linenos:
+    ```
+
+    :::
+
+    ::::
+
+    * Namespace Name: `openreg`
+    * Function Name: `custom_abs`
+    * Input Parameters:
+        * Type: `Tensor`
+        * Name: `input`
+    * Output Type: `Tensor`
+
+2. **Register Operator&Autograd Fallback:**
+
+    ::::{tab-set}
+
+    :::{tab-item} C++
+
+    ```{eval-rst}
+    .. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/OpenRegExtra.cpp
+        :language: c++
+        :start-after: LITERALINCLUDE START: CUSTOM OPERATOR DEFAULT
+        :end-before: LITERALINCLUDE END: CUSTOM OPERATOR DEFAULT
+        :linenos:
+
+    .. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/csrc/aten/OpenRegExtra.cpp
+        :language: c++
+        :start-after: LITERALINCLUDE START: CUSTOM OPERATOR FALLBACK
+        :end-before: LITERALINCLUDE END: CUSTOM OPERATOR FALLBACK
+        :emphasize-lines: 2
+        :linenos:
+    ```
+
+    :::
+
+    ::::
+
+    Use `TORCH_LIBRARY_IMPL` to register the `wrapper_custom_abs` implementation for the `custom_abs` operator in `PrivateUse1`. However, because `Autograd` is always enabled in PyTorch, PyTorch defaults to finding and executing the corresponding backward implementation even if only forward computation is required(will fallthrough in backward implementation). Therefore, we also need to register the corresponding implementation for `AutogradPrivateUse1` of the `custom_abs` operator. Fortunately, PyTorch also provides a general `Autograd Fallback` mechanism named `torch::autograd::autogradNotImplementedFallback`, if only forward computation is involved, it is equivalent to a fallthrough operation, selecting the next DispatchKey for computation; if backward computation is involved, an error is thrown.
+
+3. **Register Metadata(optional, but required by the graph mode, etc.):**
+
+    ::::{tab-set-code}
+
+    ```{eval-rst}
+    .. literalinclude:: ../../../test/cpp_extensions/open_registration_extension/torch_openreg/torch_openreg/openreg/meta.py
+        :language: python
+        :start-after: LITERALINCLUDE START: CUSTOM OPERATOR META
+        :end-before: LITERALINCLUDE END: CUSTOM OPERATOR META
+        :linenos:
+    ```
+
+    ::::
+
+    PyTorch supports registering `Meta` in both C++ and Python. Since Python registration is simpler, Python is used as an example here. Similar to the `TORCH_LIBRARY_IMPL` function in C++, Python provides the more user-friendly `torch.library.impl` decorator.
+
+### Tools
+
+Operator registration in PyTorch is complex, with diverse registration methods and numerous scenarios. Therefore, the PyTorch community has provided a number of tools to help developers quickly understand the underlying principles and assist in troubleshooting. Here we briefly introduce several commonly used tools:
+
+#### Commands
+
+PyTorch provides a set of commands prefixed with `torch._C._dispatch_` around its Dispatch feature. You can query all related interfaces using the following command:
+
+```Shell
+python -c 'import torch; print("\n".join([x for x in dir(torch._C) if x.startswith("_dispatch_")]))'
+
+...
+_dispatch_dump
+_dispatch_dump_table
+_dispatch_has_kernel
+_dispatch_has_kernel_for_any_dispatch_key
+_dispatch_has_kernel_for_dispatch_key
+_dispatch_isTensorSubclassLike
+_dispatch_is_alias_key
+_dispatch_is_included_in_alias
+_dispatch_is_main_interpreter
+_dispatch_kernel_for_dispatch_key_is_fallthrough
+_dispatch_key_for_device
+_dispatch_key_name
+_dispatch_key_parse
+_dispatch_key_set
+...
+```
+
+Here are explanations for several commonly used commands:
+
+* `torch._C._dispatch_key_set`:
+
+    Displays the DispatchKey of the current Tensor, with priority increasing from left to right.
+
+    ```Python
+    >>> import torch
+    >>> a = torch.randn(3,3,device="cuda")
+    >>> torch._C._dispatch_key_set(a)
+    'DispatchKeySet(CUDA, ADInplaceOrView, AutogradCUDA, AutocastCUDA)'
+    ```
+
+* `torch._C._dispatch_dump_table`:
+
+    Queries the support status of a given operator across different Dispatch Keys, making it easy to locate the corresponding implementation code.
+
+    ```Python
+    >>> import torch
+    >>> print(torch._C._dispatch_dump_table("aten::add.Tensor"))
+    >>> ...
+        CPU: registered at ./build/aten/src/ATen/RegisterCPU_0.cpp:1309 [kernel]
+        CUDA: registered at ./build/aten/src/ATen/RegisterCUDA_0.cpp:2420 [kernel]
+        HIP: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        MPS: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        IPU: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        XPU: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        HPU: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        VE: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        MTIA: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        MAIA: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        PrivateUse1: registered at ./build/aten/src/ATen/RegisterCompositeExplicitAutogradNonFunctional_0.cpp:1373 [default backend kernel]
+        ...
+    ```
+
+    You can easily query the corresponding implementation of the `aten::add.Tensor` operator on other platforms, so that you can track the entire operator calling process from the source code level.
+
+#### Environment Variables
+
+PyTorch also provides some dispatcher-related environment variables that can help with learning and quickly locating issues.
+
+* TORCH_SHOW_DISPATCH_TRACE
+
+    Displays detailed internal dispatch key scheduling during PyTorch execution.
+
+    ```Bash
+    export TORCH_SHOW_DISPATCH_TRACE=1
+    ```
+
+    ```Python
+    >>> import torch
+    >>> a = torch.randn(3,3)
+     [call] op=[aten::randn], key=[BackendSelect]
+       [redispatch] op=[aten::randn], key=[CPU]
+         [call] op=[aten::empty.memory_format], key=[BackendSelect]
+           [redispatch] op=[aten::empty.memory_format], key=[CPU]
+         [call] op=[aten::normal_], key=[CPU]
+    ```
+
+    You can clearly see all the underlying operators called by Python-level operators within PyTorch: including the operator name, calling hierarchy, and corresponding `Dispatch Key`.

Subject: [PATCH 0897/1424] [Inductor] Add DeviceAssert op to enable
 device-side assertion in torch.compile (#160677)

This PR introduces a device_assert op to trigger device-side assertions within torch.compile. This implementation is based on the suggestion in [this comment](https://github.com/pytorch/pytorch/issues/147282#issuecomment-2756056084).

Changes Included

- Implemented device_assert op and overrides has_side_effect to return True to avoid removal by dead code elimination.
- Commented out the assert_async_msg_decomp and functional_assert_async_msg_decomp decompositions to disable the default assert decomposition inside Inductor.
- Added lowering for torch.ops.aten._assert_async.msg to convert assert calls into the ops_handler.
- Implemented the codegen method for the device_assert op. This supports generating C++ and Triton code.
- Added test cases to verify both "should throw" and "should not throw" scenarios.

Fixes #147282

Subject: [PATCH 0907/1424] Fix running the benchmark jobs twice (#161619)

I made a mistake in https://github.com/pytorch/pytorch/pull/160935 removing this condition check.  This ran the benchmark job twice for schedule jobs, i.e. https://github.com/pytorch/pytorch/actions/runs/17266546494.  This was missed during testing because `pull_request` and `workflow_dispatch` were working ok.

Subject: [PATCH 0910/1424] [inductor] structured-log graph execution order +
 test (#160448)

Summary:

- Emit a structured trace per compiled graph execution to reconstruct execution order in TLParse.
- Adds debug.log_graph_execution(name) called from `CompiledFxGraph.__call__`, producing an artifact named inductor_graph_execution with payload {"graph": "graph_<id>"}.

Testing:
- Add inline test to verify structure and output

Subject: [PATCH 0911/1424] Updates to CuTe DSL template renderer (#161117)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Summary
This adds a few more render functions available to template writers, specifically get_output and modification. The reasons why are more clear in the next PR in this stack.

<img width="1645" height="364" alt="Screenshot 2025-08-21 at 1 48 50 PM" src="https://github.com/user-attachments/assets/2d508fda-4273-43ef-9edf-086e592e9249" />

Majority of the new cod is around the OpOverrides for CuTe DSL. It is alot to test and most of the actual testing I have been doing is via score_mods to the flash_attention at the next layer of this stack.

A bunch of score mods that me and Claude came up with , that exercise the actual ops.
``` Py

    return torch.where((q_idx + kv_idx) % 2 == 0, score, float("-inf"))

    is_causal = q_idx >= kv_idx
    is_global = kv_idx < 4
    return torch.where(is_causal | is_global, score, float("-inf"))

    is_attended = (distance == 0) | ((distance > 0) & ((distance & (distance - 1)) == 0))
    return torch.where(is_attended, score, float("-inf"))

This is bfloat16 and there are no major differences. The list of pointwise ops here isn't exhaustive but it is fairly covering

Subject: [PATCH 0912/1424] [ONNX] Fix index_put_ usage (#161263)

Summary:
It's hard to understand how it's working in most of our models, but in general it looks like `aten::copy_` is replaced incorrectly.
There are two schemas for `aten::copy_`:
1. `aten::copy_.Tensor(Tensor(a!) self, Tensor other) -> Tensor(a!)`
2. `aten::copy_(Tensor(a!) self, Tensor src, bool non_blocking=False) -> Tensor(a!)`

According to the logic in the comments we don't need one of the parameters for `aten::index_put_`.

It seems logic has been inferred from ordinary `aten::copy` where there could be a third parameter which is `non_blocking` flag.

Depending on the execution environment the sliced copying can be replaced either by first schema or by second schema with explicitly setting default parameter to `False`.

If first schema is selected it will lead to the crash (which is easily to catch in our prod env). In case of the second schema selection, there is no crash, but the third parameter is treated as `accumulate` parameter of the `index_put_` function which doesn't make sense.

So, in any case usage of the third parameter must be removed from the `aten::copy_` replacement.

For more details and check this post:
https://fb.workplace.com/groups/1405155842844877/permalink/25337687649165028/

Test Plan:

The test fails in production envirounment only.
In the test env `non_blocking` flag is mapped as `False` to the `acumulate` flag, which doesn't cause test to fail, but has no sense in terms of flags mapping.

The export works without errors, before the fix it was failing with accessing by index out of bounds vector, like this:
```
   1095     _C._jit_onnx_log("Torch IR graph at exception: ", graph)
File ~/.bento/kernels/bento_kernel_gaia_ml/1578/bento_kernel_gaia_ml_binary-inplace#link-tree/torch/onnx/utils.py:636, in _optimize_graph(graph, operator_export_type, _disable_torch_constant_prop, fixed_batch_size, params_dict, dynamic_axes, input_names, module)
    629 _C._jit_pass_lower_all_tuples(graph)
    630 # in _jit_pass_onnx, symbolic functions are called for each node for conversion.
    631 # However, there are nodes that cannot be converted without additional context.
    632 # For example, the number of outputs from split (and whether it is static or dynamic) is unknown
    633 # until the point where it is unpacked by listUnpack node.
    634 # This pass does a preprocess, and prepares the nodes such that enough context can be received
    635 # by the symbolic function.
--> 636 _C._jit_pass_onnx_remove_inplace_ops_for_onnx(graph, module)
    637 _C._jit_pass_onnx_preprocess(graph)
    639 # onnx does not support tuples, so try to remove them
RuntimeError: vector::_M_range_check: __n (which is 2) >= this->size() (which is 2)
```

The test script:
```
import torch as th
import tempfile

class CopyTest(th.nn.Module):
    def forward(
        self,
        input_th: th.Tensor
    ):
        to_fill = th.ones((3, 3))
        to_fill[:, 0] = input_th[:, 0]
        return to_fill

m = CopyTest()

test_tensor = th.zeros((3, 3))

with tempfile.NamedTemporaryFile() as f:
    th.onnx.export(
            m,
            (test_tensor,),
            f,
            export_params=True,
            opset_version=17,
            do_constant_folding=True,
            input_names=["input"],
            output_names=["features"],
            dynamo=False,
        )
```

The exported model test:
```
import torch
import onnx
import onnxruntime

model_name = '/home/ironsided/test_model.onnx'
onnx_model = onnx.load(model_name)
onnx.checker.check_model(onnx_model)

example_inputs = (torch.zeros(3, 3),)

onnx_inputs = [tensor.numpy(force=True) for tensor in example_inputs]
print(f"Input length: {len(onnx_inputs)}")
print(f"Sample input: {onnx_inputs}")

ort_session = onnxruntime.InferenceSession(
    model_name, providers=["CPUExecutionProvider"]
)

onnxruntime_input = {input_arg.name: input_value for input_arg, input_value in zip(ort_session.get_inputs(), onnx_inputs)}

# ONNX Runtime returns a list of outputs
onnxruntime_outputs = ort_session.run(None, onnxruntime_input)[0]

print(onnxruntime_outputs)
```

The produced result is correct:
```
Input length: 1
Sample input: [array([[0., 0., 0.],
       [0., 0., 0.],
       [0., 0., 0.]], dtype=float32)]
[[0. 1. 1.]
 [0. 1. 1.]
 [0. 1. 1.]]
```

Subject: [PATCH 0917/1424] Update pybind11 submodule to 3.0.1 (#160754)

Upgrade to PyBind11 v3. This allows us to strip out our own (possibly broken?) handling of the C++ ABI when building extensions, in favor of the more-complete PyBind11 internal handling.

Fixes a few test failures due to https://github.com/pybind/pybind11/issues/5774, which effectively makes the `__qualname__` attribute of functions platform-dependent.

Test plan: CI

Subject: [PATCH 0920/1424] Revert "Add inductor backend to device interface;
 make minifier_tests more device agnostic (#151314)"

This reverts commit 77bc959fe122bfd131e339ca36cab445a1860806.

Reverted https://github.com/pytorch/pytorch/pull/151314 on behalf of https://github.com/atalman due to sorry change is faling internally ([comment](https://github.com/pytorch/pytorch/pull/151314#issuecomment-3229774015))

Subject: [PATCH 0921/1424] [rfc] aot precompile with custom backend api
 (#161383)

Adding a new feature to torch.compile(fullgraph=True) which "aot_compile" a function with given example inputs.

On user side it should look like:

```
def foo(x, y):
    return x + y

compiled_fn = torch.compile(fullgraph=True).aot_compile(((torch.randn(3, 4), torch.randn(3, 4)), {}))
```

This is different from the traditional `torch.compile` workflow where compiled object will be a drop-in replacement for the original eager model:
```
tensor input -> torch.compile() -> tensor output (and populates the cache entry)
```
`aot_compile` will instead return a compiled function as result, and it's purely functional and doesn't populate the compile cache entry in dynamo:
```
tensor input -> aot_compile() -> compiled function
```
The aot compiled function will be savable and loadable on disk as well:
```
torch.compile(fullgraph=True).aot_compile(...).save_compiled_function('my/path')
compiled_fn = torch.compiler.load_compiled_function("my/path")
```

Right now we treat compiler backend as a blackbox and it needs to implement the following interface to make compile artifacts serialzable:
```
class SerializableCallable:
    def save_compile_artifacts(): ....
    def load_compile_artifacts(): ....
```
We haven't implemented this for inductor yet, but this shouldn't be an issue since we gate this feature through `torch._dynamo.config.aot_compile` (which defaults to False), and this will be left as follow up PR to the current PR.

Subject: [PATCH 0922/1424] [AOTI-FX] Enhance launch grid FloorDiv replacement
 using sympy.together.  (#161582)

# Feature
2d launch grids with dynamic shapes can contain sympy expressions like `floor(x / 128 + y / 128)`. This breaks the dynamic shapes tracer which only supports `FloorDiv`, and not `floor`.  To handle this case, call `sympy.together` prior to pattern matching to convert this to `floor((x + y) / 128)`. Then, we can recognize the pattern and map it to `FloorDiv(x + y, 128)`.

# Test plan
Added a custom Triton test exposing this. The test calls a 2d autotuned kernel with dynamic shapes.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161582
Approved by: https://github.com/nandesuka

Subject: [PATCH 0924/1424] inductor: Log the specific triton kernel that fails
 (#161452)

Added a optional name argument to SubprocPool.submit.

We record this in a dictionary, and when raising exceptions, add the name.
We manage the lifecycle the same as the pending futures.

Added a specific testcase to make sure this logs correctly.

Subject: [PATCH 0925/1424] async_compile: Fix the wait method to actually wait
 (#161561)

This method never triggered. It's used in 2 tests and they pass, so no serious
concern.

Note that I did introduce and fix a latent bug, which is if we called
shutdown_compile_workers, jobs would crash with this change due to ready_future
being finished if we called wait.

However we only call wait in tests so that bug is fine.

The other behaviour, is that if you called shutdown, I believe we may
potentially block on your first triton compile after that, until the pool was
ready. This should correctly switch to direct mode, until the pool is ready on
later warmups.

Subject: [PATCH 0930/1424] [dynamo, nested graph breaks] support very simple
 nested graph breaks (#159329)

e.g. this graph breaks once now:
```python
import torch

torch._dynamo.config.nested_graph_breaks = True

def inner(x):
    x = x + 1
    torch._dynamo.graph_break()
    return x + 2

@torch.compile(backend="eager")
def outer(x):
    return inner(x)

print(outer(torch.ones(3)))
```

Subject: [PATCH 0933/1424] [dynamo, nested graph breaks] clean up comments and
 codegen (#160138)

Fix comments to reflect that we no longer codegen cells to be sent to resume function as inputs - they are instead codegen'd after the unsupported instruction in order to build resume functions that are closures.

Also simplify some codegen.

Subject: [PATCH 0934/1424] [dynamo, nested graph breaks] prevent excessive
 recompilations (#159786)

Nested continuation function code objects are now unique w.r.t. stack trace below (and including) the current code object.

Without this change, e.g. in the added test, `f3` would be recompiled on the second graph break.

Followup: we can skip guards on continuation functions.

Subject: [PATCH 0936/1424] Ensure that tensors are contiguous before using
 no-graph MPS impl (#161641)

Fixes #161640

Check if tensors are contiguous before using the no-graph implementation. Using the script in the issue above with this change I get expected results.

```
MPS contiguous result sample: tensor([ 1.3600, -2.9516,  1.3207, -3.5132,  1.7061], device='mps:0')
MPS non-contig result sample: tensor([ 1.3600, -2.9516,  1.3207, -3.5132,  1.7061], device='mps:0')
CPU non-contig result sample: tensor([ 1.3600, -2.9516,  1.3207, -3.5132,  1.7061])
```

Subject: [PATCH 0938/1424] switch prefer_deferred_runtime_asserts_over_guards
 in export (#160111)

Summary:
In preparation for checking shape guards in export, this PR effectively switches `prefer_deferred_runtime_asserts_over_guards` to `False`, matching Dynamo.

Actually that's a lie: we switch it to `allow_complex_guards_as_runtime_asserts`, which is `False` by default but can be controlled via an internally API to be `True`. This makes the two flags synchronized, so we should be able to kill `allow_complex_guards_as_runtime_asserts` at this point.

Test Plan:
updated tests

Rollback Plan:

Subject: [PATCH 0939/1424] Updates to CuTe DSL template renderer (#161117)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Summary
This adds a few more render functions available to template writers, specifically get_output and modification. The reasons why are more clear in the next PR in this stack.

<img width="1645" height="364" alt="Screenshot 2025-08-21 at 1 48 50 PM" src="https://github.com/user-attachments/assets/2d508fda-4273-43ef-9edf-086e592e9249" />

Majority of the new cod is around the OpOverrides for CuTe DSL. It is alot to test and most of the actual testing I have been doing is via score_mods to the flash_attention at the next layer of this stack.

A bunch of score mods that me and Claude came up with , that exercise the actual ops.
``` Py

    return torch.where((q_idx + kv_idx) % 2 == 0, score, float("-inf"))

    is_causal = q_idx >= kv_idx
    is_global = kv_idx < 4

    is_attended = (distance == 0) | ((distance > 0) & ((distance & (distance - 1)) == 0))
    return torch.where(is_attended, score, float("-inf"))

This is bfloat16 and there are no major differences. The list of pointwise ops here isn't exhaustive but it is fairly covering

Subject: [PATCH 0941/1424] [TorchScript] ProfilingExecutor -
 RemoveProfileNodesAndSpecializeTypes None handling (#161538)

ProfilingGraphExecutor works like this:
1. do some unrelated JIT optimizations
2. Add profiling nodes to collect JIT information like tensor dtypes and shapes
3. Do some more unrelated JIT optimizations
4. Remove the profiling nodes and extract the tensor info, and then use the JIT tensor info to do optimizations.

This PR is intended to fix a bug in Step 4, where the profiling nodes were removed. It was previously assumed that all the things that were profiled were either Tensors or Optional[Tensor]s - otherwise, step 2 would not have introduced a profiling node.

However, we saw a case where step 3 would remove replace Optional[Tensor] inputs with `None` inputs (e.g. if a conditional that returned a Tensor or a None could be statically known to only follow the `None` branch).

To fix this, we essentially just modify the RemoveProfileNodesAndSpecializeTypes assert so that it accepts Tensors, Optional[Tensor]s, or None (the new part).

Note that this issue is probably somewhat uncommon (maybe why we didn't see it for the first 4 years that this code existed). I expect that, typically, any time that step 3 would convert `Optional[Tensor] -> None`, step 1 would have already done that. So it's difficult to reproduce in an end-to-end TorchScript workload.

Subject: [PATCH 0943/1424] Revert "[Inductor] Add DeviceAssert op to enable
 device-side assertion in torch.compile (#160677)"

This reverts commit 378edb047f83dfb84c2d9c032bddebc5e0147b8f.

Reverted https://github.com/pytorch/pytorch/pull/160677 on behalf of https://github.com/atalman due to new test is failing internally ([comment](https://github.com/pytorch/pytorch/pull/160677#issuecomment-3230152168))

Subject: [PATCH 0945/1424] [C10D] add _summarize_ranks util (#160284)

Prints ranges of ranks succinctly.

e.g.

For a strided list of ranks, summarizes down to start:stop:step
```
0:4096:512
```

Omits step if it's 1
```
0:8
```

Note: endpoints are exclusive. This may not be intuitive to everyone,
but in the first above the last rank is 3584, and in the second it is
7.

Currently, does not support combinations of striding _and_ range.  (e.g.
can not generate a representation like "0:2, 4:6, ..., 12:14".  Is this
needed / useful? If so it could be added.

Subject: [PATCH 0948/1424] Allow parallel start NUMA binding (#161576)

# Context
In #161183, we added NUMA-binding support for `Callable` entrypoints to `elastic_launch`.

However, we would raise an exception if the subprocesses would be spawned in parallel via `ThreadPoolExecutor`, which is an option configurable via the `TORCH_MP_PARALLEL_START` environment variable (see diff).

The logic here was that `os.sched_setaffinity`, which we used to set CPU affinities, is [per process](https://docs.python.org/3/library/os.html#os.sched_setaffinity), so there could be a race condition during a parallel start:

> Restrict the process with PID pid (or the current process if zero) to a set of CPUs. mask is an iterable of integers representing the set of CPUs to which the process should be restricted.

But on further reading, the Linux docs say [`sched_setaffinity` is per *thread*.](https://man7.org/linux/man-pages/man2/sched_setaffinity.2.html) As it turns out, the Python doc is a misnomer.

I [verified that `sched_setaffinity` only affects the calling thread, not the entire calling process.](https://gist.github.com/pdesupinski/7e2de3cbe5bb48d489f257b83ccddf07)

The upshot is that we actually *can* safely use the inheritance trick from #161183 even with parallel start, since the setting will be inherited from the calling thread, and `os.sched_setaffinity` only affects the calling thread.

# This PR
Remove restrictions against parallel start for NUMA binding.

Subject: [PATCH 0952/1424] [export] Support AC HOP in pre-dispatch (#161479)

Adds the pre-dispatch handling for the AC hop. This lets the HOP pre-dispatch export without actually pre-dispatch tracing into it,. However, this is not sufficient to support AC in export:
- because the HOP body will still be in torch IR, so it will fail export verifiers
- the exported module also can't be ran in eager because the AC HOP relies on partitioner to embed RNG state saving/restoring

So it must be lowered by AOT Autograd into post-dispatch first before being executed, It suffices for my purposes though.

If users had checkpoint API use in their exported model, the behavior goes from silently incorrect to now be validation error.

Models are now passing accuracy. # of graph breaks is larger because
these were not actually tested in CI (if the model fails accuracy we
do not assert on # of graph breaks).

Subject: [PATCH 0955/1424] Add option for TorchDispatchMode to ignore
 torch.compile internals (#161648)

If TorchDispatchMode.ignore_compile_internals() is True, then we turn
off the TorchDispatchMode during the compilation process, instead
turning it back on during runtime of the compiled artifact.

Test Plan:
- new test

Subject: [PATCH 0957/1424] [Inductor UT] Re-enable
 test_torchinductor_opinfo.py on XPU. (#161477)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PR #160222 replaced @skipCUDAIf with @requires_cuda_and_triton in test_torchinductor_opinfo.py, which caused the CI jobs for other devices to skip this large test suite. We attempted to revert #160222 but ran into conflicts. I then opened #160936 to revert the changes from #160222, but that resulted in CPU CI job timeouts. I also filed issue #161132 for assistance, but haven’t received a response yet.

To minimize the impact, this PR re-enables the test suite on XPU first. I will continue to seek help on re-enabling it for CPU afterwards.

Subject: [PATCH 0958/1424] Support Triton kernels in SAC region (#161541)

SAC interaction with triton kernel:
- In eager, triton ops are not dispatchable, and so it is always ignored by SAC,  i.e., always recomputed.
- In compile, although we wrap triton kernels into HOPs, allowing us to intercept them, we still recompute by default rather than save by default, so that compile maintains the invariant of using less memory than eager.
- If you want to do something else (e.g. save the output of your triton kernel) you should wrap it in a custom op.

Subject: [PATCH 0962/1424] [SymmMem] Isolate set_device tests to avoid hang
 (#161668)

`test_symmetric_memory.py` hangs like this:
```
SymmetricMemoryTest::test_empty_strided_p2p_persistent_set_device_False PASSED [5.6364s]
SymmetricMemoryTest::test_empty_strided_p2p_persistent_set_device_True ...
```

This set of tests parameterizes whether user sets the device before calling `symm_mem.emtpy`.
However, such parametrization does not work well with `MultiProcContinuousTest` because the set device will "contaminate" the next test function.

Solution is to move the "set device" tests to a separate test suite using the traditional `MultiProcessTestCase`, which would respawn processes every time.

Hang is gone now.

Subject: [PATCH 0964/1424] [2/N][SymmMem] Add MemPool allocator and tests
 (#161471)

(Porting most of #161008)

Hooking SymmetricMemory Allocator to MemPool so that user can create symmetric tensors with regular `torch.zeros`, `torch.arange` etc factories. Also so that our ops can have functional variants that create `out` tensors on symmetric memory.

To end users, this PR supports a python UI as follows:
```
allocator = symm_mem.get_mempool_allocator(device)
mempool = torch.cuda.MemPool(allocator)
with torch.cuda.use_mem_pool(mempool):
    tensor = torch.arange(numel, dtype=dtype, device=device)
```

Added tests for both use cases above.

Subject: [PATCH 0966/1424] [4/N][SymmMem] Add `get_remote_tensor` + move up
 `get_buffer` and `get_signal_pad` (#161533)

Stack from [ghstack](https://github.com/ezyang/ghstack) (oldest at bottom):

`get_remote_tensor `: return a symmetric tensor given a peer rank.

The difference between `get_buffer` API and `get_remote_tensor` API:
- the former accepts an offset, whereas the latter doesn't
- the latter returns a symmetric tensor at `hdl.offset` on `peer`.

As a refactorization, this PR also moves the implementation of `get_buffer` and `get_signal_pad` to the `SymmetricMemory` level as their code is common to all backends.

Subject: [PATCH 0969/1424] kill allow_complex_guards_as_runtime_asserts
 (#160198)

Summary: Since `allow_complex_guards_as_runtime_asserts` is now sync'd with `prefer_deferred_runtime_asserts_over_guards`, we can kill the former (especially since it was a export-only concept).

Test Plan:
updated tests

Rollback Plan:

Subject: [PATCH 0971/1424] [RELAND] Close some sources of fake tensor leakage
 (#161589)

Reland of https://github.com/pytorch/pytorch/pull/159923

Couple of fixes:
1. When we run into an operation we didn't proxy, we end up emitting fake constants. We detect this and warn using the FQN of the lifted constant. We warn because some internal users complained it was regressing their exportability.

2. Previous attribute mutation detection logic in non-strict didn't account for nested module structure. This fixes silent incorrectness issue of exporting esm and qwen in non-strict

3. We modify yolov3 to fix the previous silent incorrect behaviour
4. We use strict export for levit_128 because it errors in non-strict due to more strict side effect checking

When upgrading torchbench pin, opacus_cifar10 seems to not run on eager anymore. I verified this by pushing a temporary PR on master with new pin. So i added it to expect_fail list.

Subject: [PATCH 0980/1424] [DTensor] Wrap sharding prop error with contextual
 exception (#161574)

Mainly, this helps tell the user more info about the operator that
failed to run if it fails during sharding propagation.

Previously, only this exception would be raised:
```
RuntimeError: ('Attempted to flatten sharded dimension 1, ', 'but only the leftmost dim of a Flatten can be sharded.')
```

Now you get both the above exception as well as

```
The above exception was the direct cause of the following exception:
RuntimeError: Sharding propagation failed for Op(op=aten.view.default, args_schema=Spec((Replicate(), Shard(dim=0), Shard(dim=1), Shard(dim=2)) on (8, 8, 4)), [64, 4] @ mesh: (1, 2, 2, 2))
```

<stacktrace omitted>
<details><summary>detailed error</summary>

```

Subject: [PATCH 0981/1424] [MPS] Migrate round unary op to Metal (#161712)

And actually use the right function, as [`torch.round`](https://docs.pytorch.org/docs/stable/generated/torch.round.html) doesn't use `std::round`, but rather `std::rint`, which can be easily seen by running something like
```python
import torch
print(torch.arange(-3., 3., step=.5, device='mps').round())
print(torch.arange(-3., 3., step=.5, device='mps').cpu().round())
```

Before this change it printed
```
tensor([-3., -3., -2., -2., -1., -1.,  0.,  1.,  1.,  2.,  2.,  3.], device='mps:0')
tensor([-3., -2., -2., -2., -1., -0.,  0.,  0.,  1.,  2.,  2.,  2.])
```
But after this change results match

Subject: [PATCH 0982/1424] [cuBLASLt][FP8] `cuBLASLt` appears to support
 float8 rowwise-scaling on H100 (#161305)

Following #157905 I think the macro around
```
  TORCH_INTERNAL_ASSERT(use_rowwise == false, "rowwise scaled_gemm not supported with blaslt");
```
was never updated and this would cause `float8` tests to fail. Also it appears the `Lt` accepts two inputs with `e4m3` and `e5m2` dtypes simultaneously, so removing that check here as well...

Subject: [PATCH 0986/1424] Revert "[dynamo] [guard] Add caching for inside
 torch.compile.disable function to avoid unnecessary recompilation. (#160934)"

This reverts commit 8f31aa97a3e1e17bed29b6cedf9884f0c6b145e9.

Reverted https://github.com/pytorch/pytorch/pull/160934 on behalf of https://github.com/anijain2305 due to causes memory leak leading to OOMs ([comment](https://github.com/pytorch/pytorch/pull/160934#issuecomment-3234426359))

Subject: [PATCH 0988/1424] [Inductor] Add DeviceAssert op to enable
 device-side assertion in torch.compile (#160677)

This PR introduces a device_assert op to trigger device-side assertions within torch.compile. This implementation is based on the suggestion in [this comment](https://github.com/pytorch/pytorch/issues/147282#issuecomment-2756056084).

Changes Included

- Implemented device_assert op and overrides has_side_effect to return True to avoid removal by dead code elimination.
- Commented out the assert_async_msg_decomp and functional_assert_async_msg_decomp decompositions to disable the default assert decomposition inside Inductor.
- Added lowering for torch.ops.aten._assert_async.msg to convert assert calls into the ops_handler.
- Implemented the codegen method for the device_assert op. This supports generating C++ and Triton code.
- Added test cases to verify both "should throw" and "should not throw" scenarios.

Fixes #147282

 fudge_factors for MI355 (#161429)

This PR fixes:

- Numpy >= 2.1 version detection (instead of python 3.13 version detection) to skip some tests (numpy 2.1 can be installed for older python versions)

Subject: [PATCH 0990/1424] kill allow_complex_guards_as_runtime_asserts
 (#160198)

Summary: Since `allow_complex_guards_as_runtime_asserts` is now sync'd with `prefer_deferred_runtime_asserts_over_guards`, we can kill the former (especially since it was a export-only concept).

Test Plan:
updated tests

Subject: [PATCH 0992/1424] [PT2] Add fastResizeToZero to all static dispatch
 kernels (#161679)

Summary:
Add fastResizeToZero whenever we are reusing output tensors. Otherwise it keeps throwing warning
```
Warning: An output with one or more elements was resized since it had shape [10], which does not match the required output shape [181]. This behavior is deprecated, and in a future PyTorch release outputs will not be resized unless they have zero elements. You can explicitly reuse an out tensor t by resizing it, inplace, to zero elements with t.resize_(0). (function _resize_output_check)
```

Test Plan:
Run local replayer.

```

Subject: [PATCH 0994/1424] [inductor][mm] restructure decompose k (#161026)

# why

- make it easier to integrate into lookup table later

# what

- current version generates templates on the fly and uses them
  to generate a single choice
- lookup table and performance model work best when there is a
  stable set of templates (with predictable names) and those
  are then parametrized
- this change makes it so that there is a single DecomposeK template
  with a stable name, and the k split is the only parametrization we do

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py::TestMaxAutotune::test_max_autotune_decompose_k_dynamic_False_bfloat16_sizes1 -v

Subject: [PATCH 0996/1424] [inductor][decompose-k] make part of template
 heuristics (#161098)

# why

- enable it to go through commont template heuristics point
- make easier to use in common extension point e.g. lookup table

# what

- break template heuristic into base + triton
- move k_split generation logic into a templateheuristic for decompose k
- register through normal mechanism

- to make testing work, add a context manager to temporarily set
  template heuristics for a template/op to empty (effectively skipping
  it). This is used for decompose k test to disable triton choices

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v

Subject: [PATCH 0998/1424] Support Triton kernels in SAC region (#161541)

SAC interaction with triton kernel:
- In eager, triton ops are not dispatchable, and so it is always ignored by SAC,  i.e., always recomputed.
- In compile, although we wrap triton kernels into HOPs, allowing us to intercept them, we still recompute by default rather than save by default, so that compile maintains the invariant of using less memory than eager.
- If you want to do something else (e.g. save the output of your triton kernel) you should wrap it in a custom op.

Subject: [PATCH 1000/1424] [Dynamo] Fix weakref.proxy error when
 `torch.compile` (#161508)

Fixes #159258

The error occurs when we attempt to create a weak reference from a weak reference proxy.
https://github.com/pytorch/pytorch/blob/e9d42b3880dcdbd823bbdc9370c8b0b3af0ba2e3/torch/_dynamo/guards.py#L2910-L2915

In fact, we shouldn't create a weak reference from another reference or proxy, as it would check in CPython.
https://github.com/python/cpython/blob/f60f8225ed146a8f9b5fbf1eeed3474782127ea8/Objects/weakrefobject.c#L410-L418

However, `__weakrefoffset__` is not equal to **0** when the `guarded_object` is in `weakref.ProxyTypes`, and it will wrongly create a weak reference for the `weakref.ProxyTypes`. I think this could be a bug from CPython, but we can prevent it by adding more weakref type checks (`weakref.ProxyTypes` contains `weakref.ProxyType` and `weakref.CallableProxyType`) here.

Subject: [PATCH 1002/1424] Revert "kill
 allow_complex_guards_as_runtime_asserts (#160198)"

This reverts commit 69d91b94ba5366f4444d8cb8fd3dab4de4f04d3d.

Reverted https://github.com/pytorch/pytorch/pull/160198 on behalf of https://github.com/jeffdaily due to let's revert again instead of waiting for forward fix, see earlier comments ([comment](https://github.com/pytorch/pytorch/pull/160198#issuecomment-3235165462))

Subject: [PATCH 1012/1424] [export] Support complex constant in serde
 (#161517)

Summary:

Fixes #160749

For a model like
```
class M(torch.nn.Module):
    def forward(self, x):
        s = torch.sin(x)
        z = 1j * s
        return z
```
Its graph will be
```
graph():
    %x : [num_users=1] = placeholder[target=x]
    %sin : [num_users=1] = call_function[target=torch.ops.aten.sin.default](args = (%x,), kwargs = {})
    %mul : [num_users=1] = call_function[target=torch.ops.aten.mul.Tensor](args = (%sin, 1j), kwargs = {})
    return (mul,)
```

`1j` will appear as a constant complex argument in the `aten.mul`

Test Plan:
buck2 run mode/dev-nosan caffe2/test:test_export -- -r test_complex_constant

Rollback Plan:

Subject: [PATCH 1018/1424] Fix `SequentialLR` deprecate warning about invoke
 `step(epoch)` (#149392)

Fixes #116776 #76113 #113222 #67958
## Changes

- Refactor `LRScheduler.step` method, leave `epoch` check logic in public method `step`
- Move update `lr` logic to `_update_lr` method
- Make `SequentialLR` use `_update_lr` to avoid unnecessary warning message

## Test Result

```bash
pytest test/optim/test_lrscheduler.py -vv
```

pripority, which means if the test specifies to use CPU for testing while CUDA is
available on the host, the barrier() will use CUDA. To avoid this and better respect
`self.device_type`, we add this branch to enforce barrier() to use CPU when
`self.device_type` is CPU and other accelerator is also available.

**Test**
`pytest test/distributed/tensor/test_dtensor_testbase.py`

**Debugging Output**
```
# from init_process_group()
init pg: backend=gloo, device_id = None
default_pg has backend: gloo, device_types: [device(type='cuda'), device(type='cpu')]

# from barrier()
barrier: device_ids = [10], devices = [], device = None, PG=[device(type='cuda'), device(type='cpu')]
```

Subject: [PATCH 1023/1424] [SymmMEM] Fix test_empty_strided_p2p_persistent
 (#161677)

test_empty_strided_p2p_persistent allocates persistent symm memory tensors. However, it uses the same alloc_id for different tests, which could cause troubles if these tests are ran under the same process. This PR fixes the issue by using a different alloc_id for different test.

https://github.com/pytorch/pytorch/pull/161668 should also fix the issue but we can land this PR for a safer test.

Subject: [PATCH 1026/1424] [inductor] Fix SubgraphInfo round trip (#161779)

Currently `numels` is not specific to a created subgraph since it is not retrieved by `dataclasses.fields(SubgraphInfo)` due to it not being type annotated, see [ref](https://docs.python.org/3/library/dataclasses.html#module-dataclasses:~:text=The%20%40dataclass%20decorator%20examines%20the%20class%20to%20find%20fields.%20A%20field%20is%20defined%20as%20a%20class%20variable%20that%20has%20a%20type%20annotation.%20With%20two%20exceptions%20described%20below%2C%20nothing%20in%20%40dataclass%20examines%20the%20type%20specified%20in%20the%20variable%20annotation.).

So for example the following would happen:

```
self.numels = {"x": sympy.Integer(5)}
subgraph_name = "<x>"
with self.create_subgraph_body(subgraph_name):
     self.numels = {"x", sympy.Integer(7)}
# this would print that x has size 7, not the original value of 5
print(self.numels)
# numels would be None because dataclasses.fields(SubgraphInfo) does not include numels
# since it is not type annotated
print(self.subgraph_bodies[subgraph_name])
```

Subject: [PATCH 1027/1424] [MPS] sparse add unary funcs + add for sparse
 tensors (#160839)

Adds several unary functions and add. Enables tests for unary functions in test_sparse but not enabling other tests yet, needs more ops before we fully migrate to testing SparseMPS with `test_sparse.py`

Pull Request resolved: https://github.com/pytorch/pytorch/pull/160839

Subject: [PATCH 1031/1424] make einsum produce contiguous inputs in more cases
 (#161755)

Fixes #161729
Written by codex
This won't produce contiguous inputs for all einsum applications, because we flatten all right-only and left-only dimensions, so if right and left operand dimensions are interleaved in output, we cannot (with current algo) produce contiguous output, however, for common cases like in the linked issue it works. Let's see what CI says

Subject: [PATCH 1038/1424] [inductor][triton] support JITCallable._hash_lock
 (#161768)

Fixes #161618

Triton # 7974 introduces a threading.RLock() in JITCallable, which is not pickle-able. This PR adds this field to the list of un-pickleable fields that need to be handled specially.

Subject: [PATCH 1039/1424] [inductor] Lift fw_compiler and bw_compiler as
 toplevel functions. (#161762)

This is a no-op refactor to compiler_fx which lifts the logic of fw_compiler and bw_compiler to toplevel, so that they can be reused in a different stack (e.g. precompile).

Subject: [PATCH 1042/1424] [inductor][heuristics registry] missing heuristic
 is not an error anymore, cross device heuristics (#161767)

# why

- not having a heuristic is an error but should not crash, just provide 0 configs
- some heuristics are cross device type
- cleaner to be explicit about being cross device type than having to
  enumerate every possible device type

# what

- on registration, supply device_type=None (explicitly) to say this
  heuristic is cross device
- test to guard the heuristics hierarchies

# testing

```
python3 -bb -m pytest test/inductor/test_template_heuristics_registry.py
```

 than cuda (#161795)

# why

- untested so far

# what

- add an empty config heuristic for all devices for decompose k
- the cuda heuristic, because it is more specific, will still be picked
  up
- add notes explaining how to enable on other devices

# testing

```

Subject: [PATCH 1045/1424] Enable XPU path for FlexAttention (#143553)

[#RFC153024](https://github.com/pytorch/pytorch/issues/153024)

**Motivation**

1. The Attention has been the critical performance bottleneck in the current LLM models, and FlexAttention is a good choice to cover the broad variants in the transformers series models. With FlexAttention, it is easy for us to enable the paged attention and fused SDPA  in the transformers repo on XPU device. Besides,  it also provide a candidate to process attention in LLM ecosystem libraries ., e.g., vLLM, SGLang on XPU device.
2. FlexAttention is good start point to push the intel triton based GEMM kernel to be matured. FlexAttention provide both flexattention kernel and flexdecoding kernel to cover both compute bound and memory bound GEMM computation, and  different shapes should also been supported to serve LLM inference., e.g. head_dim=64, 96, 128, 256.

**What does this PR do?**

 1. Enable the device type for Flexattention kernel  and UTs to ensure all important UTs pass on XPU device.
 2. For E2E model inference, ensure the functionality  of LLM models inference with FlexAttention to be ready.

Subject: [PATCH 1049/1424] [SymmMEM] Move AsyncTP tests to a seperate test
 class (#161820)

We move AsyncTP tests to a seperate test suite because 1) Async TP ops are not the core symmetric memory APIs, they are more like applications, 2) MultiProcContinuousTest will skip all the following tests if a test fails (we should fix this too). We still want to get the test signals for the core
symmetric memory APIs when Async TP ops fail.

Subject: [PATCH 1050/1424] [MPS] Add slow version of `kthvalue` (#161817)

Which heavily borrows implementation logic from `topk`
As this method is non-deterministic, modified the logic for cpu-ops indices comparison with just an equality statement, as by default random numbers picked for input tensor allow for quite a lot of overlaps

Subject: [PATCH 1051/1424] Revert "Cleanup stale submodule directories after
 checkout (#161748)"

This reverts commit 0e45023cf9cbe1cf18279c1b0d391ea9464e7731.

Reverted https://github.com/pytorch/pytorch/pull/161748 on behalf of https://github.com/malfet due to I still see the same failures, and could not understand, from the log whether those checks are running on not ([comment](https://github.com/pytorch/pytorch/pull/161748#issuecomment-3238791895))

Subject: [PATCH 1052/1424] [WIP] more aggressive persistent reduction
 (#161055)

Gives 18% speedup on rms norm (2048, 32768). And we have seen other instances where inductor is not aggressive enough about codegening persistent reductions - e.g. 39% on [this kernel from torch ao](https://github.com/pytorch/pytorch/issues/159769#issuecomment-3188568335).

Codegen-ing persistent reductions can be risky if you run out of registers. Here, I'm effectively making persistent reductions an option of looped reductions by setting RBLOCK == rnumel, so that we can still fallback to looped reductions as needed.

As criteria:

- there needs to be significant memory savings from doing a persistent reduction (by keeping memory in register and avoiding another iteration over input)
- we should not be coalescing on x dimension, otherwise large rblock will inhibit coalescing
- we should not be especially register or arithmetic intensive (this last part uses mem_ops_per_thread, but could be improved).

Still need to do dashboard run, although I'm not sure we get a lot of large rblock in our benchmarks.

Subject: [PATCH 1053/1424] [MPS] sparse add unary funcs + add for sparse
 tensors (#160839)

Adds several unary functions and add. Enables tests for unary functions in test_sparse but not enabling other tests yet, needs more ops before we fully migrate to testing SparseMPS with `test_sparse.py`

Subject: [PATCH 1056/1424] Add batch option for send/recv_object_list
 (#160342)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`send_object_list` and `recv_object_list` use regular `send`/`recv` P2P ops which means that they will create 2-rank NCCL communicators between ranks if the communicators have not been initialized.

This adds an option `use_batch` which will call the send/recv with `batch_isend_irecv` which will re-use the communicators already initialized for collectives in the group.

---

BatchP2P ops, creates (or use existing) communicator keyed by device index
Regular P2P Ops, creates (or use existing) dedicated 2-rank communicators keyed by “rank1:rank2”

Subject: [PATCH 1058/1424] [FlexAttn] Fix Paged Attention Accuracy via Upper
 Mask Mod and Prevent Invalid Memory Access  (#160861)

Fixes #159247
Issue 1: Accuracy Problem with Non-Divisible KV Sequences
---------------------------------------------------------

### Background

Paged attention in flex decoding produced inaccurate results when KV sequence length is not divisible by block size. For example, when `KV_S = 64` and `block_size = 128`, the output didn't match standard attention accuracy.

### Root Cause
The current paged attention does not apply upper mask mod when converting from logical to physical mask mod. Instead, it uses a noop_mask by default which makes all the values unmasked, leading to an accuracy mismatch. Adding a upper mask mod according to the origin actual kv_len (64 in this test case) resolves the issue.

### Solution

*   **Applied proper upper bound masking**: Updated all calls to `convert_logical_block_mask` to pass `kv_len` as a tensor with proper shape `[B, KV_S]` to provide information of actual batched KV sequence length. The function now correctly applies upper bound checks using the actual KV sequence lengths for each batch

### Files Modified
*    `torch/nn/attention/experimental/_paged_attention.py`: Added `kv_len` parameter as a tensor to `get_mask_mod` and applied upper mask to the new mask mod.
*   `test/inductor/test_flex_attention.py`: Fixed all related `kv_len` parameter call in the tests
*   `test/inductor/test_flex_decoding.py`: Fixed all related `kv_len` parameter call in the tests

Issue 2: Invalid Memory Access (IMA) in Triton Kernels
------------------------------------------------------

### Background

The Triton kernel for flex attention was experiencing invalid memory access errors when running with compute sanitizers, particularly with short KV sequences and small batch sizes.

### Root Cause

*   Kernel launches CTAs (Cooperative Thread Arrays) proportional to GPU's multi-processor count (108 via `SPLIT_KV`)
*   With small workloads, many CTAs remain idle but still attempt to access `kv_indices` with invalid `indices_idx` values
*   This caused out-of-bounds memory access violations

### Solution

Implemented boundary checks with early exit:

1.  **Added `MAX_VALID_KV_IDX` parameter** in `torch/_inductor/kernel/flex/flex_decoding.py`

    *   Calculate maximum valid KV index based on actual `kv_indices` tensor size and pass it to Triton template
2.  **Added early exit logic** in `torch/_inductor/kernel/flex/templates/flex_decode.py.jinja`

    *   Boundary checks before accessing `kv_indices` in both normal and full blocks
    *   Idle CTAs with invalid `indices_idx` skip computation entirely

This prevents invalid memory access while reducing wasted computation on idle thread blocks.

Testing & Validation
--------------------

### Accuracy Tests

*   Added comprehensive test cases covering KV sequences not divisible by block sizes
*   Verified output matches standard attention for various sequence length combinations

### Sanitizer Results

`========= COMPUTE-SANITIZER Starting standalone test_max_autotune... Running test_max_autotune on device: cuda max_autotune config: True test_max_autotune completed successfully! Test passed! ========= ERROR SUMMARY: 0 errors`

**Before**: More than 13720 invalid memory access errors with sanitizers
**After**: Clean execution with 0 errors

Both fixes work together to ensure paged attention produces accurate results while running safely without memory access violations.

Subject: [PATCH 1059/1424] [Inductor] update exp codegen for better precision
 (#161829)

Prior to this PR, we have:
```
[Default Behavior] uses `tl.math.exp({x})`:
eager diff: tensor(2.6935e-06, device='cuda:0', dtype=torch.float64)
compile diff: tensor(9.2757e-06, device='cuda:0', dtype=torch.float64)
eager_latency:0.0013996509159580942, compile_latency:0.0013981951951980592

TORCHINDUCTOR_USE_FAST_MATH=1 uses `tl.extra.libdevice.exp2(tmp0 * 1.4426950408889634)`:
eager diff: tensor(2.2315e-06, device='cuda:0', dtype=torch.float64)
compile diff: tensor(3.5329e-06, device='cuda:0', dtype=torch.float64)
eager_latency:0.0013982331859319662, compile_latency:0.0013824134564199367

Update inductor to use `tl.extra.libdevice.exp(tmp0)`:
eager diff: tensor(2.3421e-06, device='cuda:0', dtype=torch.float64)
compile diff: tensor(2.3421e-06, device='cuda:0', dtype=torch.float64)
eager_latency:0.0014109122834153282, compile_latency:0.0014062877025520593
```

Since `tl.extra.libdevice.exp` leads to both better precision and on-par latency, we use it by default now.

Note that `tl.extra.libdevice.exp` used to have a perf issue in [January 2025](https://github.com/triton-lang/triton/issues/5735) since it used due to `ex2.approx.f32` instead of `ex2.approx.ftz.f32`. So `tl.extra.libdevice.exp2(tmp0 * 1.4426950408889634)` was used as a workaround. I double checked that the issue is resolved and `tl.extra.libdevice.exp` also uses [ex2.approx.ftz.f32](https://github.com/triton-lang/triton/issues/5735#issuecomment-3238421293) today.

Subject: [PATCH 1060/1424] [Inductor][CPP] Optimize config selecting for micro
 gemm when number of mxn blocks can not occupy all the threads (#161144)

If number of mxn blocks can not occupy all the threads, use smaller register block size will get better performance since the computing size per thread is smaller.
It may get ~20% performance improvement for the real case `m1_n512_k4096`.

Subject: [PATCH 1061/1424] Fix forced copying def_property_readonly for
 FunctionSchema & friends (#161301)

This took me a bit to figure out and I'm pretty sure I've looked at
this code before. Pybind uses
`return_value_policy::reference_internal` for `def_property`, which
[causes the owning object to be kept alive for the lifespan of the
return
value](https://pybind11.readthedocs.io/en/stable/advanced/functions.html),
allowing the getter to safely avoid copying the property
value. However, lambdas act like they return `auto`, not
`decltype(auto)`, so our lambdas themselves were forcing copies!

Testing: observed std::vector<Argument> copying disappear in Linux
perf profile of someOpInfo._schema.arguments/returns (in
_python_dispatch.correct_storage_aliasing).

- Empty containers are Falsey
- Hoist cheap checks first
- Microbenchmarked single-element set access method

Benchmark code:
```
import timeit

to_test = [
    ('list(x)', 'x = set([3])'),
    ('x[0]', 'x = [3]'),
    ('list(x)[0]', 'x = set([3])'),

]

for (stmt, setup) in to_test:
    res = timeit.timeit(stmt=stmt, setup=setup)
    print(f"Time for `{stmt}`: {res}")
```

Result with Python 3.13 on Mac (with excess digits manually trimmed; directionally matches result on Linux)
```
Time for `list(x)`: 0.03418
Time for `x[0]`: 0.00852
Time for `list(x)[0]`: 0.03561
Time for `next(iter(x))`: 0.02278
```

FWIW, I was surprised by this result, so I guess I'm glad I wrote the benchmark!

Subject: [PATCH 1069/1424] Stop trying to intern arguments in
 PyObject_FastGetAttrString (#161432)

If we want them interned, we should intern at callsites. (The numpy reference has bit rotted; see https://github.com/numpy/numpy/commit/b222eb66c79b8eccba39f46f020ed8303614a87f#diff-6bdb6105198083838f51c57b55b3a49472ed23043bb40018f1ea41138e687163)

Profiling a simple torchdispatch benchmark with perf before/after seems to show that time spent copying std::strings and interning Python strings is gone, though there is some noise and the improvement is very small.

Subject: [PATCH 1071/1424] [inductor] check block options after broadcasting
 and singleton dims have been removed (#161602)

This will allow for some more cases to use tensor descriptors e.g. before the following block params would not match
because the innermost dimension does not have stride 1
```python
block_params=BlockParameters(shape=[64, 4, 1, 1], block_shape=[((XBLOCK + 3)//4), Min(4, XBLOCK), 1, 1], strides=[0, 1, 0, 0], offsets=[(xoffset//4), ModularIndexing(xoffset, 1, 4), 0, 0])
```
After broadcasting dimensions and singleton dimensions are removed:
```python
block_params=BlockParameters(shape=[4], block_shape=[Min(4, XBLOCK)], strides=[1], offsets=[ModularIndexing(xoffset, 1, 4)])
```

Subject: [PATCH 1075/1424] [OpenReg] Add Event&Stream Support for OpenReg
 Backend (#160099)

Referring to the signatures and functions of `Stream` and `Event` in CUDA, we use CPU multithreading
and conditional variables to implement equivalent capabilities as the underlying foundation of torch_openreg.

**Changes:**

- Add stream capabilities for OpenReg
- Add event capabilities for OpenReg
- Add kernel launch entrypoint for OpenReg
- Add testcases about stream and event for OpenReg
- Add example for OpenReg
Pull Request resolved: https://github.com/pytorch/pytorch/pull/160099

 OpenReg is a C++ backend library that simulates the behavior of a CUDA-like device on a CPU. Its core objective is **not to accelerate computation or improve performance**, but rather to **simulate modern CUDA programming, enabling developers to prototype and test in an environment without actual GPU hardware**. The current design principles are as follows:
 
-* **API Consistency**: Provide an interface consistent with the CUDA Runtime API, allowing upper-level applications (like PyTorch's PrivateUse1 backend) to switch and test seamlessly.

 * **Functional Consistency**: Provide behavior consistent with the CUDA Runtime, such as memory isolation, device context management, etc.
-* **Completeness**: Aim to support PrivateUse1 device integration and safeguard the third-party device integration mechanism, without striving to cover all capabilities of the CUDA Runtime.

 2. **Deallocation**: Memory is freed using `munmap`.
 3. **Authorization**: When a legitimate memory access is required, an RAII guard restores the memory permissions to `PROT_READ | PROT_WRITE`. The permissions are automatically reverted to `PROT_NONE` when the scope is exited.
 
+### Stream&Event Principles
+
+Simulating creation, release and synchronization for event and steam:
+
+1. **Event**: Each event is encapsulated as a task function and placed into a stream, which acts as a thread. Upon completion of the task, a flag within the event is modified to simulate the event's status.
+2. **Stream**: When each stream is requested, a new thread is created, which sequentially processes each task in the task queue within the stream structure. Tasks can be wrappers around kernel functions or events.
+3. **Synchronization**: Synchronization between streams and events is achieved using multithreading, condition variables, and mutexes.

-The following is a simple code snippet demonstrating how to use the core features of the OpenReg library.
-
-```cpp
-#include "openreg.h"
-#include <iostream>
-#include <vector>
-#include <cstdio>
-
-#define OR_CHECK(call) do { \
-    orError_t err = call; \
-    if (err != orSuccess) { \
-        fprintf(stderr, "OR Error code %d in %s at line %d\n", err, __FILE__, __LINE__); \
-        exit(EXIT_FAILURE); \
-    } \

-    int device_count = 0;
-    OR_CHECK(orGetDeviceCount(&device_count));
-    std::cout << "Found " << device_count << " simulated devices." << std::endl;

-    int current_device = -1;
-    OR_CHECK(orSetDevice(1));
-    OR_CHECK(orGetDevice(&current_device));
-    std::cout << "Set current device to " << current_device << "." << std::endl;
-
-    const int n = 1024;
-    const size_t size = n * sizeof(int);
-    int *h_a, *d_a;
-    OR_CHECK(orMallocHost((void**)&h_a, size));
-    OR_CHECK(orMalloc((void**)&d_a, size));
-
-    orPointerAttributes attr;
-    OR_CHECK(orPointerGetAttributes(&attr, d_a));
-    std::cout << "Pointer " << (void*)d_a << " is of type " << attr.type
-              << " on device " << attr.device << std::endl;

+Please refer to [example](example/example.cpp) for example.
+
+The command to compile example.cpp is as follow:
+
+```Shell
+mkdir build
+
+pushd build
+cmake ..
+make -j 32
+popd
+
+g++ -o out example/example.cpp -L ./build -lopenreg
+LD_LIBRARY_PATH=./build ./out
 ```
 
-## Next Steps
+The output is as follow:
 
-To better support PrivateUse1 device integration, the following capabilities are planned for the future:
+```Shell
+Current environment have 2 devices
+Current is 0 device
+All tasks have been submitted.
+Kernel execution time: 0.238168 ms
+Verification PASSED!
+```
+
+## Next Steps
 
-* **Stream Support**: Provide the ability to simulate CUDA Streams.
-* **Event Support**: Provide the ability to simulate CUDA Events.
-* **Cross-Platform Support**: Add support for Windows and macOS (low priority).
+The most basic functions of the OpenReg backend are currently supported, and will be dynamically optimized and expanded based on the needs of PyTorch integration.

Subject: [PATCH 1077/1424] [OpenReg] Integrate Event&Stream from OpenReg
 Backend into PyTorch (#160100)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We integrated the openreg backend’s `Stream` and `Event` into PyTorch, all of which are similar
to other accelerators like `CUDA`, `XPUs`, etc.
Pull Request resolved: https://github.com/pytorch/pytorch/pull/160100
Approved by: https://github.com/albanD
ghstack dependencies: #161603, #160099, #161773

Subject: [PATCH 1078/1424] Revert "[4/N][SymmMem] Add `get_remote_tensor` +
 move up `get_buffer` and `get_signal_pad` (#161533)"

This reverts commit 95516ad7e6d92ed131fb6057b29ec52e73190e3c.

Reverted https://github.com/pytorch/pytorch/pull/161533 on behalf of https://github.com/atalman due to Multiple internal failures on PR #[161471](https://github.com/pytorch/pytorch/pull/161471) will need to land it via co-dev ([comment](https://github.com/pytorch/pytorch/pull/161533#issuecomment-3239278635))

Subject: [PATCH 1081/1424] Pass shared_ptr by value (#161834)

The way AsyncAllreduceCUDADeviceWork is currently implemented,
using it will force a copy of `shared_ptr<gloo::Context>`
because `std::move` does nothing for a const ref.

This PR changes the param type to shared_ptr<> instead of the
const ref. This allows more efficient parameter passing.

Here's an example that demonstrates the issue:

```cpp
#include <memory>
#include <iostream>

struct Foo {};

void useFoo_ref(const std::shared_ptr<Foo>& f) {
    std::shared_ptr<Foo> internal = std::move(f);
    std::cout << "use_count: " << internal.use_count() << '\n';
}

void useFoo_val(std::shared_ptr<Foo> f) {
    std::shared_ptr<Foo> internal = std::move(f);
    std::cout << "use_count: " << internal.use_count() << '\n';
}

int main() {
    std::shared_ptr<Foo> f1 = std::make_shared<Foo>();
    useFoo_ref(std::move(f1)); // prints "use_count: 2"

    std::shared_ptr<Foo> f2 = std::make_shared<Foo>();
    useFoo_val(std::move(f2)); // prints "use_count: 1"
}
```

This also aligns well with [C++ Core Guidelines][1] for handling
smart pointers.

Subject: [PATCH 1086/1424] [CPU][Inductor] Improve performance of A16W8 GEMM
 template (#161148)

**Summary**
This PR improves the performance of A16W8 GEMM template by
- Removing the config with block_n=48 & block_m=16 as it is not very efficient.
- Using AMX microkernel when M >= 5 so that we use AMX instead of AVX512 for M=5~31.
- Converting int8 values to bf16 with intrinsics instead of `at::vec::convert` as the latter does not have optimized implementation for this case.

We saw up to >10% performance gain in various cases of running Llama-3.1-8b-instruct.

**Test plan**
Already covered by UT.

Subject: [PATCH 1090/1424] [2/N][SymmMem] Add MemPool allocator and tests
 (#161471)

(Porting most of #161008)

Hooking SymmetricMemory Allocator to MemPool so that user can create symmetric tensors with regular `torch.zeros`, `torch.arange` etc factories. Also so that our ops can have functional variants that create `out` tensors on symmetric memory.

To end users, this PR supports a python UI as follows:
```
allocator = symm_mem.get_mempool_allocator(device)
mempool = torch.cuda.MemPool(allocator)
with torch.cuda.use_mem_pool(mempool):
    tensor = torch.arange(numel, dtype=dtype, device=device)
```

Added tests for both use cases above.

Subject: [PATCH 1095/1424] Remove background thread UT on XPU to fix CI
 (#161844)

# Motivation
Because we revert `torch._C._set_allocator_settings` in https://github.com/pytorch/pytorch/pull/161626, this UT becomes invalid.
Fix https://github.com/pytorch/pytorch/issues/161697

Subject: [PATCH 1098/1424] [4/N][SymmMem] Add `get_remote_tensor` + move up
 `get_buffer` and `get_signal_pad` (#161533)

Stack from [ghstack](https://github.com/ezyang/ghstack) (oldest at bottom):

`get_remote_tensor `: return a symmetric tensor given a peer rank.

The difference between `get_buffer` API and `get_remote_tensor` API:
- the former accepts an offset, whereas the latter doesn't
- the latter returns a symmetric tensor at `hdl.offset` on `peer`.

As a refactorization, this PR also moves the implementation of `get_buffer` and `get_signal_pad` to the `SymmetricMemory` level as their code is common to all backends.

Subject: [PATCH 1100/1424] Skip compilation when FX graph has no calls and
 returns empty (#160536)

Fixes #160437

Summary:
This PR avoids compiling empty FX graphs generated during graph breaks. If there are no calls in the graph, we can just return the empty list of instructions.

More precisely,
In compile_and_call_fx_graph, if the FX graph contains no calls (count_calls(self.graph) == 0) and the return value list is empty, we now return an empty instruction list immediately

Impact:
module: dynamo

Subject: [PATCH 1101/1424] [CUDA] Reuse blocks with record_stream during CUDA
 Graph capture in the CUDACachingAllocator (#158352)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Introduction

During CUDA Graph capture, the CUDA caching allocator currently defers reclaiming blocks until capture ends. This is because CUDA forbids querying events recorded during capture (the CUDA operation is not executed during the capture stage), so the allocator cannot use its normal event-based logic. However, capture records an DAG (we call it **capturing graph**) of work. We can use the capturing graph to determine when a block’s old lifetime is fully before future work, and safely reuse it within the same capture.

This PR adds an experimental flag `graph_capture_record_stream_reuse: True|False (default: False)`. When enabled, the allocator inserts lightweight free markers and uses capture ordering to decide if a freed block is safe to reuse during capture. If the proof cannot be established, we fall back to the existing post-capture path.

## Terms

* **Free marker**: A capture-legal no-op (created with `cudaGraphAddEmptyNode`) inserted after the last captured use of the block on each stream that used it.
* **Terminal**: The set of the lastest operations of the stream (or the capturing graph). Any newly captured op on that stream will attach after all nodes in this set. For a stream currently capturing, it is the set of nodes returned in `dependencies_out` by `cudaStreamGetCaptureInfo`.

## When can we reuse a block during capture?

### Strong Rule (Graph-Wide Safety)

This rule provides a universal guarantee that a block is safe for reuse by any stream in the graph.

> A block is safe to reuse if every free marker is a predecessor of every terminal of all active streams in the graph.

Why it's safe:

This rule establishes a strict global ordering. Since any new operation on any stream must be appended after that stream's terminals, this condition guarantees that the block's new lifetime begins only after its old lifetime has completely ended everywhere. This prevents lifetime overlaps when the graph is replayed, ensuring correctness.

### Per-stream Rule (A Practical Optimization)

The strong rule, while safe, is often unnecessarily restrictive. The `DeviceCachingAllocator` introduces a crucial constraint that allows for a simpler check.

In `DeviceCachingAllocator`, `get_free_block` only returns blocks whose `block->stream == p.stream()`. In other words, we never reuse a block on a stream different from the allocation stream. This means we don't need to verify safety across the entire graph. We only need to confirm that the block is safe to reuse from the perspective of its own allocation stream.

> Reuse a block for allocations on stream S if every free marker is a predecessor of every node in the terminal set of S.

In short, a block is considered **reusable** on stream S as long as all marker marking it "free" are guaranteed to complete before any new work that might need it on stream S begins.

## Implementation

* On `free(block)` during capture
  * For each stream in `block->stream_uses` and the allocation stream, insert a free marker (empty node) and make it that stream’s tail.
  * If we cannot place markers for all such streams (for example, a stream is not in capture), defer to the post-capture path.
  * Otherwise, store the marker handles and keep the block in the capture-private structures.
* On `allocate(stream)` during capture (attempt per-stream reclaim)
  * Query the allocation stream S’s terminal via `cudaStreamGetCaptureInfo`.
  * For each deferred block, check whether it is allocated on this stream, and each of its free markers is a predecessor of the terminal.
    * If yes, hand the block to S for immediate reuse within the same capture.
    * If no, keep it deferred; it will be reconsidered as capture progresses and S’s terminal advances.
* On capture end
  * Any still-deferred blocks follow the existing post-capture reclamation (event insertion/polling). External behavior remains unchanged if we cannot prove safety during capture.

## Examples (2 streams)

<img width="641" height="801" alt="pytorch-remove-cudagraph-defer-reclaiming (6)" src="https://github.com/user-attachments/assets/41adc835-d448-483b-99ba-b4341cb7d2a2" />

* Case 0 — Unsafe
The two frees are not ordered with respect to each other. For stream 1, the other stream’s free marker does not precede this stream’s terminal, so the per-stream condition fails.
Counterexample intuition for the unsafe setups: imagine `f2(x)` runs for a long time. If DeviceCachingAllocator reused block `x` on a stream whose terminal is not ordered after the free markers, the new lifetime could overlap the old one on replay, risking use-after-free or data corruption. The per-stream rule prevents exactly this.
* Case 1 — Reusable on stream 1
Stream 1’s terminal is after both frees, so every free marker precedes stream 1’s terminal. The block is reusable for allocations on stream 1.
* Case 2 — Not reusable on stream 2, but this cannot occur in `DeviceCachingAllocator`
This depicts reusing the block on stream 2 while stream 1’s free is not yet ordered before stream 2’s terminal. Though the block is not safe to reuse on stream 2, DeviceCachingAllocator will not choose that block for stream 2 anyway: `get_free_block` rejects blocks whose `stream != p.stream()`. So this case is unreachable.
* Case 3 — Safe (strong rule holds)
In this scenario, the terminal nodes of all streams are positioned after the block's free markers, satisfying the strong rule. This guarantees the block is safe for reuse by any stream in the capturing graph. However, since `DeviceCachingAllocator ` only reuses a block on its original allocation stream, verifying this strong condition is unnecessary. We only need to ensure the per-stream rule is met for the specific stream requesting the block.
* Case 4 — Freeing after a join
See the note below.

## Edge Case: Freeing after a join

Our current dependency tracking has a limitation in scenarios where a block is freed after a stream join, see @galv's [comments here](https://github.com/pytorch/pytorch/pull/158352#pullrequestreview-3112565198)).

In the case 4, we have a missed opportunity. Because the block's usage is not explicitly marked, we cannot determine that the block's actual last use may have occurred much earlier, long before the join. Then, we must wait for the subsequent join before the block can be reused.

## Thanks
Thanks to @galv for his great idea around graph parsing and empty nodes.

Subject: [PATCH 1105/1424] Revert "[CUDA] Reuse blocks with record_stream
 during CUDA Graph capture in the CUDACachingAllocator (#158352)"

This reverts commit 190c391a28845a14df26abb228d26aa813efb20c.

Reverted https://github.com/pytorch/pytorch/pull/158352 on behalf of https://github.com/atalman due to Broke cuda 13.0 nightly builds https://github.com/pytorch/pytorch/actions/runs/17382188549/job/49341981474 ([comment](https://github.com/pytorch/pytorch/pull/158352#issuecomment-3242871629))

1. `pytorch-linux-jammy-cuda12.8-cudnn9-py3-gcc9-inductor-benchmarks` is used by almost all inductor jobs including nightly benchmark
2. `pytorch-linux-jammy-cuda12.8-cudnn9-py3.12-gcc9-inductor-benchmarks` runs inductor unit tests with python 3.12
3. `pytorch-linux-jammy-cuda12.8-cudnn9-py3.13-gcc9-inductor-benchmarks` runs inductor unit tests with python 3.13
4. `pytorch-linux-jammy-py3-gcc11-inductor-benchmarks` runs inductor unit tests on CPU

My proposal here is to clean up (2) and (3) and to keep (1) under the same setup from https://ghcr.io/pytorch/torchbench.  Simplicity is the key here as inductor workflows are getting more and more complex:
1. Unit tests for Python variant like 3.12 and 3.13 were useful when they were first added to CI.  They are much less useful now.  [Flambeau](https://hud.pytorch.org/flambeau/s/3876ec7b-43f0-42c6-bfbf-899035e5bb77) shows a 0.97 correlation between them.  And we are also moving to 3.14 nowadays.  I want to choose 3.12 for (1), but will do this separately.  This is also what TorchBench and vLLM are using on CI.
1. We are gradually cleaning up 3.9 on CI https://github.com/pytorch/pytorch/issues/161167

Another BE change here is to rename the jobs various inductor workflows because I think names like `linux-jammy-cuda12_8-py3_10-gcc9-inductor-build` is too long and confusing to look at, better just use human-friendly names like `inductor-build`.  Other information is already spelled out in the build environment.

Subject: [PATCH 1109/1424] Fix type checking for persistent loads in the
 weights-only unpickler (#161661)

The error message here implies that we can only call `self.persistent_load(...)` for ints or tuples, but due to the second part of the type check being inverted, weights-only unpickler will throw an exception iff `pid` is an int.

Subject: [PATCH 1110/1424] Defer loading hipify until it is needed (#160824)

Saves a few milliseconds when running a test case:

Before:
```
$ PYTORCH_TEST_WITH_DYNAMO=1 python test/dynamo/cpython/3_13/test_float.py GeneralFloatCases.test_float_pow
frames [('total', 1), ('ok', 1)]
inline_call []
.
----------------------------------------------------------------------
Ran 1 test in 1.497s
```

After:
```
$ PYTORCH_TEST_WITH_DYNAMO=1 python test/dynamo/cpython/3_13/test_float.py GeneralFloatCases.test_float_pow
frames [('total', 1), ('ok', 1)]
inline_call []
.
----------------------------------------------------------------------
Ran 1 test in 0.909s
```

Subject: [PATCH 1113/1424] Make distributed modules importable even when
 backend not built (#159889)

This PR is greatly simplified now that it stacked on top of a PR that builds with distributed always. We only need to stub functions that may not be defined due to a backend not being enabled.

Subject: [PATCH 1114/1424] [AOTI] split too long string to smaller pieces when
 its length larger than 16000, fix msvc c2026. (#161850)

Split too long string to smaller pieces when its length larger than 16000, fix msvc c2026.

reproducer:
```cmd
pytest test\inductor\test_aot_inductor.py -v -k test_runtime_checks_large_cpu
```

Error message:

For MSVC c2026:
https://learn.microsoft.com/en-us/cpp/error-messages/compiler-errors-1/compiler-error-c2026?view=msvc-170

We can split too long string to smaller pieces, it can fix this issue.

Subject: [PATCH 1116/1424] [dynamo] Prevent unnecessary recompile on disabled
 functions in the compiled frame (#161883)

Trying out a re-impl of https://github.com/pytorch/pytorch/pull/160934

The above PR led to OOM, most likely because of the cache holding to a nested function (which if not held in the cache would have been garbage collected), which holds on to cuda tensors in its closure.

Subject: [PATCH 1117/1424] test: ensure editable cached wrapper is respected
 (#160943)

## Summary
- add a test verifying that editing the local cache wrapper is picked up after Dynamo reset

## Testing
- `lintrunner -a` *(fails: FLAKE8 failure, TEST_HAS_MAIN failure, CODESPELL failure, PYFMT failure)*
- `PYTHONPATH=. python test/inductor/test_codecache.py TestPyCodeCache.test_editable_cached_wrapper -v`

Subject: [PATCH 1119/1424] Fixes broken memory_viz link in CUDA memory docs
 (#161426)

Fixes #161375

The  "Using the visualizer" section in torch_cuda_memory.md had a link to  https://pytorch.org/memory_viz written in inline Markdown link form. Strangely the same syntax worked earlier on the page as the issuer mentioned, but in this spot it's rendered sa a broken link.

I wasn't able to pinpoint why the second occurrence was treated differently, but switching it to the Markdown autolink form fixes the problem consistently. I tested this by rebuilding the docs locally with make html and serving the HTML with a local http.server. With the autolink, the link resolves correctly.

Subject: [PATCH 1122/1424] Make pattern matcher resilient to ddes (#161843)

Motivated by the following discord support chat: https://discord.com/channels/1189498204333543425/1409578286186758195

```
import torch
@torch.compile(fullgraph=True, mode='reduce-overhead')
def get_mask(W: torch.Tensor, percentage_nonzeros: torch.Tensor):
    total_elements = W.numel()
    k = int(total_elements * percentage_nonzeros)
    top_k_indices = torch.topk(torch.abs(W).flatten(), k)[1]
    mask = torch.zeros(total_elements, dtype=torch.bool, device=W.device)
    mask.scatter_(0, top_k_indices, True)
    mask = mask.view(W.shape)
    return mask

x = torch.randn((128, 64), device='cuda')
p = torch.tensor(0.50, device='cuda')
get_mask(x, p)
```

Results in

```
InductorError: GuardOnDataDependentSymNode: Could not guard on data-dependent expression Eq(TruncToInt(zuf0), 1) (unhinted: Eq(TruncToInt(zuf0), 1)).  (Size-like symbols: none)
```

Subject: [PATCH 1123/1424] [DTensor] select strategy with no redistribute when
 redistribute cost is 0 (#161882)

Before this PR, the `_select_strategy` always selects the first strategy with minimum redistribute cost. This causes unexpected behavior when
- multiple strategies have 0 redistribute costs
- the first one with 0 redistribute cost may perform local chunking

E.g. in memory efficient SDPA, the default orders of candidate strategies have a `Shard(2)` one before the `Replicate()` one. https://github.com/pytorch/pytorch/blob/main/torch/distributed/tensor/_ops/_matrix_ops.py#L500-L512
When the input is `Replicate()`, `_select_strategy` will pick the `Shard(2)` strategy and do local chunking first, before local computation. This is clearly unexpected to users.

In this PR, we improve `_select_strategy` so that when multiple strategies have 0 redistribute cost, we prioritize the one which keeps input unchanged.

Subject: [PATCH 1125/1424] Improve error message for unsupported padding
 config (#160866)

Fixes #160053

The previous error message `Only 2D, 3D, 4D, 5D padding with non-constant  padding are supported for now`  was not clear

now we have

Subject: [PATCH 1130/1424] [CUDAGraph] add config to error on skipping
 cudagraph (#161862)

Many users want a config to force all cuda ops captured by cudagraph. When not possible, pt2 should error.

This PR adds `torch._inductor.triton.cudagraph_or_error` for that (default as False). Also added an environment variable `TORCHINDUCTOR_CUDAGRAPH_OR_ERROR` to control.

Subject: [PATCH 1132/1424] [ONNX] Refactor torchscript based exporter
 (#161323)

Refactor torchscript based exporter logic to move them to a single (private) location for better code management. Original public module and method apis are preserved.

- Updated module paths in `torch/csrc/autograd/python_function.cpp` accordingly
- Removed `check_onnx_broadcast` from `torch/autograd/_functions/utils.py` because it is private&unused

@albanD / @soulitzer could you review changes in `torch/csrc/autograd/python_function.cpp` and
`torch/autograd/_functions/utils.py`? Thanks!

## BC Breaking
- **Deprecated members in `torch.onnx.verification` are removed**

-## Symbolic functions Opsets
-
-Opset 9 is the base version. It is selected as the base version because
-
-1. It is the first opset version supported by PyTorch export.
-2. Opset 9 is more robust than previous opset versions. Opset versions like 7/8 have limitations

-    we chose to handle them as special cases separately.
-
-Backward support for opset versions beyond opset 7 is not in our roadmap.
-
-For opset versions other than 9, by default they will inherit the symbolic functions defined in
-symbolic_opset9.py.
-
-To extend support for updated operators in different opset versions on top of opset 9,
-simply add the updated symbolic functions in the respective symbolic_opset{version}.py file.
-Check out topk in symbolic_opset10.py, and upsample_nearest2d in symbolic_opset8.py for example.
-
-## Editing Symbolic Files
-
-- Use the internal `registration.onnx_symbolic` decorator to register a new symbolic function. Search for `def reshape(g, self, shape):` to see an example.
-- Parameter names must *exactly* match the names in
-  aten/src/ATen/native/native_functions.yaml, because
-  dispatch is done with keyword arguments.
-- Looking for inplace ops? They're detected by
-  `_jit_pass_onnx_remove_inplace_ops_for_onnx`, and
-  transparently dispatched to their non inplace versions in
-  "run_symbolic_function". See Note [Export inplace](#export-inplace)
-
-### A note on Tensor types
-
-In general, we should avoid depending on the type of Tensor Values contained
-within the trace graph. However, this is sometimes unavoidable (due to ONNX
-spec requirements, etc). The TensorType object has accessors for these properties that return the property if it is statically known and return nullopt otherwise.
-
-In general, we should prefer to rely on the least specific information possible.
-For example, not relying on tensor properties at all is better than relying
-on the number of dimensions which is better than relying on
-concrete shapes. Doing so will make the export symbolics
-more robust to different graphs.
-
-### Extra context for symbolic functions
-
-The first argument of a symbolic function is always a `GraphContext` object.
-
-`GraphContext` contains all methods defined in a `torch.Graph` object and context
-for the symbolic function.
-
-In general, symbolic functions only require inputs and attributes to
-the original node. An example of a symbolic function needing context is
-`prim::Loop`. It needs access to the sub-block of the original node.
-
-### Export inplace
-
-It would be better for us to export inplace annotations,
-than to not export them, since it is useful information that can
-help the target of an ONNX export export more efficiently. However,
-ONNX doesn't currently formalize inplace. Fortunately, it's sound to drop
-inplace annotations, but we are losing information this way.
-
-### Pointwise by scalar
-
-What happens if you add a tensor with a constant (e.g., x + 2)?  There are
-some moving parts to implementing the ONNX translation in this case:
-
-- By the time we get the scalar in a symbolic function here, it is no longer a
-  Python long/float, but a PyTorch tensor with `numel == 1` (eventually, we want
-  it to be a zero dim tensor but this change has not happened yet.) However, the
-  type of this scalar is *exactly* what the user wrote in Python, which may not
-  match the tensor it is being added to. PyTorch will do implicit conversions on
-  scalars; however, ONNX will not, so we must do the conversion ourselves. This
-  is what `symbolic_helper._if_scalar_type_as()` and
-  `_jit_pass_onnx_scalar_type_analysis` does.
-
-- Dispatch to these functions takes advantage an outrageous coincidence
-    between the tensor and scalar name.  When we add two tensors together,
-    you get the dispatch:
-
-    add(*[self, other], **{"alpha": alpha})
-
-    When you add a tensor and a scalar, you get the dispatch:
-
-    add(*[self], **{"other": other, "alpha": alpha})
-
-    By having the argument name line up with the name of the scalar attribute
-    if it exists, we can write a single function for both overloads.

+
+    Args:

+        args:
+
+            args can be structured either as:
+
+            1. ONLY A TUPLE OF ARGUMENTS::
+
+                args = (x, y, z)
+
+            The tuple should contain model inputs such that ``model(*args)`` is a valid
+            invocation of the model. Any non-Tensor arguments will be hard-coded into the
+            exported model; any Tensor arguments will become inputs of the exported model,
+            in the order they occur in the tuple.
+
+            2. A TENSOR::
+
+                args = torch.Tensor([1])
+
+            This is equivalent to a 1-ary tuple of that Tensor.
+
+            3. A TUPLE OF ARGUMENTS ENDING WITH A DICTIONARY OF NAMED ARGUMENTS::
+
+                args = (x, {"y": input_y, "z": input_z})
+
+            All but the last element of the tuple will be passed as non-keyword arguments,
+            and named arguments will be set from the last element. If a named argument is
+            not present in the dictionary, it is assigned the default value, or None if a
+            default value is not provided.
+
+            .. warning::
+                This behavior will be deprecated in a future release. Please use the

+                If a dictionary is the last element of the args tuple, it will be

+            be exported. Set this to False if you want to export an untrained model.
+            In this case, the exported model will first take all of its parameters

+                `ATen <https://pytorch.org/cppdocs/#aten>`_ is PyTorch's built-in tensor library, so
+                this instructs the runtime to use PyTorch's implementation of these ops.
+
+                .. warning::
+
+                    Models exported this way are probably runnable only by Caffe2.
+
+                    This may be useful if the numeric differences in implementations of operators are
+                    causing large differences in behavior between PyTorch and Caffe2 (which is more
+                    common on untrained models).
+
+            * ``OperatorExportTypes.ONNX_ATEN_FALLBACK``: Try to export each ATen op
+                (in the TorchScript namespace "aten") as a regular ONNX op. If we are unable to do so
+                (e.g. because support has not been added to convert a particular torch op to ONNX),
+                fall back to exporting an ATen op. See documentation on OperatorExportTypes.ONNX_ATEN for
+                context.
+                For example::

+            to target. Must be >= 7.
+        do_constant_folding: Apply the constant-folding optimization.
+            Constant-folding will replace some of the ops that have all constant inputs
+            with pre-computed constant nodes.
+        dynamic_axes:
+
+            By default the exported model will have the shapes of all input and output tensors
+            set to exactly match those given in ``args``. To specify axes of tensors as
+            dynamic (i.e. known only at run-time), set ``dynamic_axes`` to a dict with schema:
+
+            * KEY (str): an input or output name. Each name must also be provided in ``input_names`` or
+                ``output_names``.
+            * VALUE (dict or list): If a dict, keys are axis indices and values are axis names. If a

+
+        keep_initializers_as_inputs: If True, all the
+            initializers (typically corresponding to parameters) in the
+            exported graph will also be added as inputs to the graph. If False,
+            then initializers are not added as inputs to the graph, and only
+            the non-parameter inputs are added as inputs.
+            This may allow for better optimizations (e.g. constant folding) by
+            backends/runtimes.
+
+            If True, `deduplicate_initializers` pass will not be executed. This means
+            initializers with duplicated values will not be deduplicated and
+            will be treated as distinct inputs to the graph. This allows different
+            input initializers to be supplied at the runtime following export.
+
+            If ``opset_version < 9``, initializers MUST be part of graph
+            inputs and this argument will be ignored and the behavior will be
+            equivalent to setting this argument to True.
+
+        custom_opsets (dict[str, int], default empty dict): A dict with schema:
+
+            * KEY (str): opset domain name
+            * VALUE (int): opset version
+
+            If a custom opset is referenced by ``model`` but not mentioned in this dictionary,
+            the opset version is set to 1. Only custom opset domain name and version should be
+            indicated through this argument.
+
+        export_modules_as_functions: Flag to enable
+            exporting all ``nn.Module`` forward calls as local functions in ONNX. Or a set to indicate the
+            particular types of modules to export as local functions in ONNX.
+            This feature requires ``opset_version`` >= 15, otherwise the export will fail. This is because
+            ``opset_version`` < 15 implies IR version < 8, which means no local function support.
+            Module variables will be exported as function attributes. There are two categories of function
+            attributes.
+
+            1. Annotated attributes: class variables that have type annotations via
+            `PEP 526-style <https://www.python.org/dev/peps/pep-0526/#class-and-instance-variable-annotations>`_
+            will be exported as attributes.
+            Annotated attributes are not used inside the subgraph of ONNX local function because
+            they are not created by PyTorch JIT tracing, but they may be used by consumers
+            to determine whether or not to replace the function with a particular fused kernel.
+
+            2. Inferred attributes: variables that are used by operators inside the module. Attribute names
+            will have prefix "inferred::". This is to differentiate from predefined attributes retrieved from
+            python module annotations. Inferred attributes are used inside the subgraph of ONNX local function.
+
+            * ``False`` (default): export ``nn.Module`` forward calls as fine grained nodes.
+            * ``True``: export all ``nn.Module`` forward calls as local function nodes.
+            * Set of type of nn.Module: export ``nn.Module`` forward calls as local function nodes,
+                only if the type of the ``nn.Module`` is found in the set.
+
+        autograd_inlining: Flag used to control whether to inline autograd functions.
+            Refer to https://github.com/pytorch/pytorch/pull/74765 for more details.

+        check_shape: Whether to check the shapes between PyTorch and ONNX Runtime outputs
+            are exactly the same. Set this to False to allow output shape broadcasting.

+            to the ONNX model. Supply a list when there are unused inputs in the model.
+            Since unused inputs will be removed in the exported ONNX model, supplying

-    If ``model`` is not a :class:`torch.jit.ScriptModule` nor a
-    :class:`torch.jit.ScriptFunction`, this runs
-    ``model`` once in order to convert it to a TorchScript graph to be exported
-    (the equivalent of :func:`torch.jit.trace`). Thus this has the same limited support
-    for dynamic control flow as :func:`torch.jit.trace`.
-
-    Args:
-        model: The model to be exported.
-        args:
-
-            args can be structured either as:
-
-            1. ONLY A TUPLE OF ARGUMENTS::
-
-                args = (x, y, z)
-
-            The tuple should contain model inputs such that ``model(*args)`` is a valid
-            invocation of the model. Any non-Tensor arguments will be hard-coded into the
-            exported model; any Tensor arguments will become inputs of the exported model,
-            in the order they occur in the tuple.
-
-            2. A TENSOR::
-
-                args = torch.Tensor([1])
-
-            This is equivalent to a 1-ary tuple of that Tensor.
-
-            3. A TUPLE OF ARGUMENTS ENDING WITH A DICTIONARY OF NAMED ARGUMENTS::
-
-                args = (x, {"y": input_y, "z": input_z})
-
-            All but the last element of the tuple will be passed as non-keyword arguments,
-            and named arguments will be set from the last element. If a named argument is
-            not present in the dictionary, it is assigned the default value, or None if a
-            default value is not provided.
-
-            .. warning::
-                This behavior will be deprecated in a future release. Please use the
-                kwargs argument instead.
-
-            .. note::
-                If a dictionary is the last element of the args tuple, it will be
-                interpreted as containing named arguments. In order to pass a dict as the
-                last non-keyword arg, provide an empty dict as the last element of the args
-                tuple. For example, instead of::

-            be exported. Set this to False if you want to export an untrained model.
-            In this case, the exported model will first take all of its parameters

-                `ATen <https://pytorch.org/cppdocs/#aten>`_ is PyTorch's built-in tensor library, so
-                this instructs the runtime to use PyTorch's implementation of these ops.

-                    Models exported this way are probably runnable only by Caffe2.
-
-                    This may be useful if the numeric differences in implementations of operators are
-                    causing large differences in behavior between PyTorch and Caffe2 (which is more
-                    common on untrained models).
-
-            * ``OperatorExportTypes.ONNX_ATEN_FALLBACK``: Try to export each ATen op

-                fall back to exporting an ATen op. See documentation on OperatorExportTypes.ONNX_ATEN for
-                context.

-        do_constant_folding: Apply the constant-folding optimization.
-            Constant-folding will replace some of the ops that have all constant inputs
-            with pre-computed constant nodes.
-        dynamic_axes:
-
-            By default the exported model will have the shapes of all input and output tensors
-            set to exactly match those given in ``args``. To specify axes of tensors as
-            dynamic (i.e. known only at run-time), set ``dynamic_axes`` to a dict with schema:
-
-            * KEY (str): an input or output name. Each name must also be provided in ``input_names`` or
-                ``output_names``.
-            * VALUE (dict or list): If a dict, keys are axis indices and values are axis names. If a

-
-        keep_initializers_as_inputs: If True, all the
-            initializers (typically corresponding to parameters) in the
-            exported graph will also be added as inputs to the graph. If False,
-            then initializers are not added as inputs to the graph, and only

-            This may allow for better optimizations (e.g. constant folding) by

-
-            If True, `deduplicate_initializers` pass will not be executed. This means

-            input initializers to be supplied at the runtime following export.
-
-            If ``opset_version < 9``, initializers MUST be part of graph
-            inputs and this argument will be ignored and the behavior will be
-            equivalent to setting this argument to True.
-
-        custom_opsets (dict[str, int], default empty dict): A dict with schema:
-
-            * KEY (str): opset domain name
-            * VALUE (int): opset version
-
-            If a custom opset is referenced by ``model`` but not mentioned in this dictionary,
-            the opset version is set to 1. Only custom opset domain name and version should be
-            indicated through this argument.
-
-        export_modules_as_functions: Flag to enable
-            exporting all ``nn.Module`` forward calls as local functions in ONNX. Or a set to indicate the
-            particular types of modules to export as local functions in ONNX.
-            This feature requires ``opset_version`` >= 15, otherwise the export will fail. This is because
-            ``opset_version`` < 15 implies IR version < 8, which means no local function support.
-            Module variables will be exported as function attributes. There are two categories of function
-            attributes.
-
-            1. Annotated attributes: class variables that have type annotations via
-            `PEP 526-style <https://www.python.org/dev/peps/pep-0526/#class-and-instance-variable-annotations>`_
-            will be exported as attributes.
-            Annotated attributes are not used inside the subgraph of ONNX local function because
-            they are not created by PyTorch JIT tracing, but they may be used by consumers
-            to determine whether or not to replace the function with a particular fused kernel.
-
-            2. Inferred attributes: variables that are used by operators inside the module. Attribute names
-            will have prefix "inferred::". This is to differentiate from predefined attributes retrieved from
-            python module annotations. Inferred attributes are used inside the subgraph of ONNX local function.
-
-            * ``False`` (default): export ``nn.Module`` forward calls as fine grained nodes.
-            * ``True``: export all ``nn.Module`` forward calls as local function nodes.
-            * Set of type of nn.Module: export ``nn.Module`` forward calls as local function nodes,
-                only if the type of the ``nn.Module`` is found in the set.
-
-        autograd_inlining: Flag used to control whether to inline autograd functions.

-        check_shape: Whether to check the shapes between PyTorch and ONNX Runtime outputs
-            are exactly the same. Set this to False to allow output shape broadcasting.

-        check_dtype: Whether to check the dtypes between PyTorch and ONNX Runtime outputs
-            are consistent. Default to True.
-        backend: ONNX backend for verification. Default to OnnxBackend.ONNX_RUNTIME_CPU.
-        rtol: relative tolerance in comparison between ONNX and PyTorch outputs.
-        atol: absolute tolerance in comparison between ONNX and PyTorch outputs.
-        remained_onnx_input_idx: If provided, only the specified inputs will be passed
-            to the ONNX model. Supply a list when there are unused inputs in the model.
-            Since unused inputs will be removed in the exported ONNX model, supplying

Subject: [PATCH 1133/1424] Detect torch function in lists as well (#160256)

We basically follow the same pattern we do for tensor arguments. The major downside is we now have to traverse the entirety of the int list / etc where previously we didn't have. Benchmark suggests 2% regression for relevant things.

Subject: [PATCH 1135/1424] ROCm: Enable overload tests from test_matmul_cuda
 (#161540)

This patch enables hipblaslt backend tests for test_mm_bmm_dtype_overload and test_addmm_baddmm_dtype_overload.
Tests were disabled as part of #150812
Rocblas backend tests are not enabled yet, WIP.

Test command
PYTORCH_TEST_WITH_ROCM=1 pytest test/test_matmul_cuda.py -k 'test_mm_bmm_dtype_overload' -v PYTORCH_TEST_WITH_ROCM=1 pytest test/test_matmul_cuda.py -k 'test_addmm_baddmm_dtype_overload' -v

This reverts commit 9a665ca3c472384e9d722bddba79e5a7680f1abd.

Reverted https://github.com/pytorch/pytorch/pull/160750 on behalf of https://github.com/jeanschmidt due to Seems that those errors are legitimate, and there is no test plan. I'll be proceeding with a revert ([comment](https://github.com/pytorch/pytorch/pull/160750#issuecomment-3246095383))

Subject: [PATCH 1143/1424] [dynamo] Graph break on torch.cuda.sychronize
 (#161925)

Today, AOTDispatcher ignores cuda.synchornize. Even if we wrap it in
some  HOP, we need it to be a barrier op to prevent any inductor
reordering. So graph breaking.

Fixes https://github.com/pytorch/pytorch/issues/160751

Subject: [PATCH 1144/1424] [MPS] Move sparsemps testing from test_mps to
 test_sparse (#161852)

Moves Sparse MPS testing from test_mps to test_sparse. Lots of skips now but I expect to remove them iteratively once ops are implemented

Subject: [PATCH 1149/1424] Revert "Always build USE_DISTRIBUTED. (#160449)"

This reverts commit b7034e9c924412bfbe8ee25a22d7e95239b5ca65.

Reverted https://github.com/pytorch/pytorch/pull/160449 on behalf of https://github.com/jeanschmidt due to Breaking internal builds, can't be landed with forward fix due to internal tooling problems ([comment](https://github.com/pytorch/pytorch/pull/160449#issuecomment-3246689684))

Subject: [PATCH 1154/1424] [aot precompile] Handle closure variables.
 (#161990)

We previously assume aot precompile should only work on non closures. This is hard to enforce in practice because we will see a lot of cases with decorater (e.g. hugging face models)
```
def check_inputs(fn):
    def _fn(self, *args, **kwargs):
        for arg in args:
            assert arg.shape[0] > 1

        return fn(*args, **kwargs)
    return _fn

@check_inputs
def foo(x, y):
    a = x + x
    b = y + y
    c = a + b
    return c
```
It doesn't make sense to not support these cases since they are straightfowrad to do.

This PR adds the logic to handle closure and make sure they can be precompiled properly.

Subject: [PATCH 1155/1424] [ONNX] Default to dynamo export (#159646)

Set dynamo=True and enable fallback.

1. Implemented the compatible behavior where BytesIO objects as `f` is accepted
2. Update tests to explicitly set dynamo=False

#151693

Subject: [PATCH 1156/1424] [SymmMem] Make sure CUDA runtime is initialized
 before NVSHMEM init (#161232)

Previously, without calling `torch.empty` before NVSHMEM init, we see error below:
```
src/host/init/init.cu:nvshmemi_check_state_and_init:1117: nvshmem initialization failed, exiting
src/host/util/cs.cpp:21: non-zero status: 16: Device or resource busy, exiting... mutex destroy failed
```
Fixing it by calling a `cudaFree(nullptr)` to make sure CUDA runtime is initialized before NVSHMEM init.
Removing all `torch.empty(1)` calls from tests.

Reverted https://github.com/pytorch/pytorch/pull/161572 on behalf of https://github.com/seemethere due to This appears as though its causing downstream build failures in inductor workflows and for developers working locally. Going to revert out of an abundance of caution. ([comment](https://github.com/pytorch/pytorch/pull/161572#issuecomment-3247121981))

Subject: [PATCH 1161/1424] [SymmMem] Use non-blocking version of getmem
 (#162006)

As titled, so that the `getmem` calls in the loop are non-blocking, so that we max out the issuance rate.
Also had a single `nvshmem_quiet()` at the end to make sure all the getmem calls complete.

The functions here expect to return pointers, but currently aren't returning anything.  Make them return NULL.

The properties array wants an extra set of braces.  One pair for the array, another for the first item in the array.

Subject: [PATCH 1163/1424] [inductor] add notion of extra_kwargs for
 mm_configs (#161123)

# why

- some kwargs are choice independent but rather
  always the same for a specific op or template
- this enables us to track those differently than the
  choice ones, and thus enables interception of them
  cleaner
- maybe_append_choices can then be simplified to
  just pass through the kwargs

# what

- hookup for template heuristics to have per template/op extra
  kwargs that are always the same, for all choices
- hookup for the called to get_mm_configs to provide template/op
  kwargs to override some of the template/choice kwargs

this pr does not use the new machinery, and everything is empty
for now. subsequent prs start using it to simplify ops

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1164/1424] [inductor] move tma workspace in heuristics
 (#161124)

# why

- another step towards get_mm_configs providing
  all the kwargs needed to add a choice from
  a template. This in turn will allow us to send
  all templates through one single call, and handle modifications

# what

use the infrastructure for template heuristics to provide extra kwargs
that are fixed for a template/op pair to provide the workspace_arg for
all the tma templates

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v -k tma
```

Subject: [PATCH 1165/1424] [inductor] move addmm/baddbmm template args into
 heuristics (#161125)

# why

- another step towards get_mm_configs providing
  all the kwargs needed to add a choice from
  a template. This in turn will allow us to send
  all templates through one single call, and handle modifications

# what

- use the infrastructure for template heuristics to provide extra kwargs
  that are fixed for a template/op pair to provide the prefix args
  and epilogue function/fn for addmm/baddbmm

- expand kernelinputs to also be able to shuttle around non tensor
  inputs (scalars) as is needed for alpha and beta

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v -k addmm
```

Subject: [PATCH 1166/1424] [inductor] move scaled_mm template args into
 heuristics (#161126)

# why

- another step towards get_mm_configs providing
  all the kwargs needed to add a choice from
  a template. This in turn will allow us to send
  all templates through one single call, and handle modifications

# what

- use the infrastructure for template heuristics to provide extra kwargs
  that are fixed for a template/op pair to provide the suffix args
  and epilogue function/fn for scaled_mm

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1167/1424] [inductor][ez] ExternChoice with
 maybe_append_choice (#161336)

# why

- make the API for ExternChoice the same as KernelTemplate
- make it possible to use the same retrieval point as templates

# what

- add a maybe_append_choice to ExternChoice that under the hood
  invokes self.bind

This pr does not actuate the new path, but just exposes it

# testing

Subject: [PATCH 1169/1424] [inductor][ez] add hook for heuristics to adjust
 kernel input nodes (#161339)

# why

- some templates e.g. scale_mm need to unsqueeze/squeeze the nodes
  for codegen and heuristics

- unified place where we can just adjust them for the template

# what

- inside get_mm_configs, return not the passed in kernel inputs,
  but allow the template heuristic to adjust them if necessary

- the default implementation right now just passes them back

this diff just adds the functionality, but does not exercise it
other than the default (passthrough)

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1172/1424] build: Add fallback commands to setup.py (#162009)

Adds fallback commands for the following:
* python setup.py install
* python setup.py develop

Ideally these should just work and should provide backwards compat.

Thought process here is that multiple people rely on these commands and just because setuptools wants to drop support for this I don't think a lot of our downstream users who build from source are expecting these to be gone.

This should provide some room for developers to move away from these commands until we have a unified frontend for doing all of these commands that should abstract most of these away.

+# Accelerator Integration
+
+Since PyTorch 2.1, the community has made significant progress in streamlining the process of integrating new accelerators into the PyTorch ecosystem. These improvements include, but are not limited to: refinements to the `PrivateUse1` Dispatch Key, the introduction and enhancement of core subsystem extension mechanisms, and the device-agnostic refactoring of key modules (e.g., `torch.accelerator`, `memory management`). Taken together, these advances provide the foundation for a **robust**, **flexible**, and **developer-friendly** pathway for accelerator integration.
+
+## Why Does This Matter?
+
+This integration pathway offers several major benefits:
+
+* **Speed**: Extensibility is built into all core PyTorch modules. Developers can integrate new accelerators into their downstream codebases independently—without modifying upstream code and without being limited by community review bandwidth.
+* **Future-proofing**: This is the default integration path for all future PyTorch features, meaning that as new modules and features are added, they will automatically support scaling to new accelerators if this path is followed.
+* **Autonomy**: Vendors maintain full control over their accelerator integration timelines, enabling fast iteration cycles and reducing reliance on upstream coordination.
+
+## About This Document
+
+This guide aims to provide a **comprehensive overview of the modern integration pathway** for new accelerator in PyTorch. It walks through the full integration surface, from low-level device primitives to higher-level domain modules like compilation and quantization. The structure follows a **modular and scenario-driven approach**, where each topic is paired with corresponding code examples from [torch_openreg][OpenReg URL], an official reference implementation.
+
+The goal is to help developers:
+
+* Understand the full scope of accelerator integration;
+* Follow best practices to quickly launch new accelerators;
+* Avoid common pitfalls through clear, targeted examples.
+
+## Target Audience
+
+This document is intended for:
+
+* **Accelerator Developers** who are integrating accelerator into PyTorch;
+* **Advanced PyTorch Users** interested in the inner workings of key modules;
+
+## Quick Overview
+
+This document outlines the key processes and practical scenarios involved in integrating new devices into PyTorch, providing developers with a comprehensive and detailed guide for bringing up new backends. The discussion is structured around four major axes:
+
+* **Runtime**: Covers core components such as Event, Stream, Memory, Generator, Guard, Hooks, as well as the supporting C++ scaffolding.
+* **Operators**: Involve the minimum necessary set of operators, forward and backward operators, fallback operators, fallthroughs, STUBs, etc. in both C++ and Python implementations.
+* **Python Frontend**: Focuses on Python bindings for modules and device-agnostic APIs.
+* **High-level Modules**: Explores integration with major subsystems such as `AMP`, `Compiler`, `ONNX`, and `Distributed` and so on.
+
+Next, we will officially embark on the integration journey for a new PyTorch accelerator.
+

+# Operator Registration
 
 For new accelerators, one of the most important and fundamental aspects of integration is supporting high-performance operators. To facilitate operator adaptation for users and accelerator developers, PyTorch provides multiple methods for developing and registering operators in both `Python` and `C++`. The following sections detail some of PyTorch's fundamental capabilities for operator registration.

 PyTorch currently has over 3500 built-in operators (including related operator variants). This represents a significant workload from any perspective, and supporting this massive number of operators in a short period of time is no easy task. Therefore, as the first step in developing new backend operators, our goal should be to focus on the essential operators. For other operators, we can first use the community's fallback mechanism to support the feature as the first priority. After that, we can gradually complete other operators to improve the performance of the new backend.

Subject: [PATCH 1176/1424] [Reland][Inductor] Prune configs that require more
 shared memory than the hardware limit.  (#161996)

Summary:
This is a re-land of [PR161040](https://github.com/pytorch/pytorch/pull/161040), which had previously caused test failures on AMD GPUs. The tests are now configured to target only NVIDIA GPUs.

This diff removes configurations that exceed the hardware shared memory limit, which causes the following compilation error:
```
No valid triton configs. OutOfMemoryError: out of resource: triton_mm Required: 327680 Hardware limit:232448 Reducing block sizes or `num_stages` may help.
```

Test Plan:
```
pytest test/inductor/test_max_autotune.py
pytest test/inductor/test_triton_heuristics.py
```

Subject: [PATCH 1178/1424] [DTensor] forbid view ops to redistribute when
 local split is impossible (#161950)

This PR is a followup to https://github.com/pytorch/pytorch/pull/149764.

In that PR, it only forbids illegal view due to `Flatten`; this PR also forbids illegal view caused by `Split`.

This PR also updates the error message to be less about internal implementation details, which users may find confusing.

Subject: [PATCH 1179/1424] [Intel GPU] Fix XPU SDPA default priority_order UT
 fail (#161690)

Fixes #161483

When the whole `test/test_transformers.py` file is run, the case `test_default_priority_order` can pass because other xpu cases would call SDPA so that the priority order is set by https://github.com/pytorch/pytorch/blob/eec876deb659fe667aac2d97a48d7451c3e88dee/aten/src/ATen/native/mkldnn/xpu/Attention.cpp#L98-L112

However, when the case `test_default_priority_order` is run separately, the priority order is unset so that this case would fail. This PR fix this case.

This function has come up in DTensor perf work, and I had a nitpick on #160256 so here it is. I have neither compiled nor measured this, but am reasonably confident it's better nonetheless.

Subject: [PATCH 1184/1424] Add inline fast paths for SymInt operators
 (#161586)

If SymInt::maybe_as_int() returns non-empty, then we get an inline
fast path. The philosophy here (as with the previous PR) is to
preserve performance in the "plain old ints" case.

Observed time spent in SymInt functions in computeStorageNBytes to
drop (and not cost shift elsewhere in the function) after this change,
profiling detach() using code similar to the benchmark from #160580
and Linux perf.

Subject: [PATCH 1186/1424] Make distributed modules importable even when
 backend not built (#159889)

This PR is greatly simplified now that it stacked on top of a PR that builds with distributed always. We only need to stub functions that may not be defined due to a backend not being enabled.

Subject: [PATCH 1187/1424] [AOTI] Fix a bug from load_constants (#161887)

Summary:
we have
```
std::vector<size_t> constants_internal_offset(
        num_constants - num_folded_constants);
```

but the for loop does not consider it
```
for (size_t i = 0; i < num_constants; i++) {
...
constants_internal_offset[i]
...
```
even in the for loop, it does
```
bool from_folded = this->constant_from_folded(i);
      if (from_folded) {
        continue;
      }
```
but `i` could still be wrong

 (#161953)

Summary: Save the config args that Inductor burns into `inductor_metadata` so we can optionally pass them to any Jit Hooks that are set. This allows us to pass them to Tritonparse.

Subject: [PATCH 1194/1424] port distributed tensor parallel test files for
 Intel GPU (#161261)

In this pr, we port test/distributed/parallel 4 test files and test/distributed/debug 1 test file for Intel GPU
We could enable Intel GPU with following methods and try the best to keep the original code styles:

1. Use torch.accelerator for general gpu
2. Skip the case if running on xpu which has known issues

Subject: [PATCH 1195/1424] Support generic dynamic shape with padding
 (#160997)

Summary:
Inductor has the following configurations:

config.comprehensive_padding
config.padding_alignment_bytes
config.padding_stride_threshold

In the case of static shape by enabling these three options Inductor will generate code for Flexible layout tensors that tries to pad up all stride dimension to be a multiple of config.padding_alignment_bytes for strides above: config.padding_stride_threshold. In the case where dynamic shapes is enabled no padding is done today.
This PR introduces the following configuration which allows the user to specify they wish to generated a padded stride even in the case of dynamic shape operations. This is mainly done so we don't break the previous behaviour of not padding up dynamic shape use cases. The config.padding_stride_threshold does not apply since the values of the strides are dynamic.

config.pad_dynamic_shapes

In addition to this a new mode "python_slow" has been added to launch grid calculation which achieves the same ceildiv behaviour that is generally applicable to integer division. This is done to prevent test regressions and make wrapper_fxir codegen more generic.

Subject: [PATCH 1199/1424] Contiguous subgraph decomposition (#161241)

## Summary

Adds a subgraph decomposition for addmm and mm that performs well on large `K` compared to `M` and `N`, and functions well as an alternative to `split-k` on AMD (transposed only), which does not support AMD currently.

## Background

On AMD (MI300x), for a matmul A * B, if B is non-contiguous, the resulting matmul is quite a bit slower.
For example:
```
  args[0]: TensorBox(StorageBox(
    InputBuffer(name='arg0_1', layout=FixedLayout('cuda:0', torch.float16, size=[1024, 178176], stride=[178176, 1]))
  ))
  args[1]: TensorBox(StorageBox(
    InputBuffer(name='arg1_1', layout=FixedLayout('cuda:0', torch.float16, size=[178176, 6144], stride=[1, 178176]))
  ))
```
is a lot slower than:
```
  args[0]: TensorBox(StorageBox(
    InputBuffer(name='arg0_1', layout=FixedLayout('cuda:0', torch.float16, size=[1024, 178176], stride=[178176, 1]))
  ))
  args[1]: TensorBox(StorageBox(
    InputBuffer(name='arg1_1', layout=FixedLayout('cuda:0', torch.float16, size=[178176, 6144], stride=[6144, 1]))
  ))
```
This PR adds a subgraph decomposition to test out whether making B contiguous is faster than just using the normal kernels.

## Data

I ran this on unique non-contiguous shapes from torchbench/huggingface and got these speedups:

## Results

The largest shape gain, `256,197951,512`, seemed to be driven by a case where the extern kernel is way faster than the best triton configs on the recursive autotune:

It seems to perform really well for high values of `K` vs `N` and `M`.

## Conclusion
Contiguous Subgraph Decompositionseems worthwhile for `mm` and `addmm`, but not `bmm`, and has a very large improvment on low `M`, low `N`, and high `K` shapes.

Subject: [PATCH 1202/1424] [inductor][ez] add hook for heuristics to adjust
 kernel input nodes (#161339)

# why

- some templates e.g. scale_mm need to unsqueeze/squeeze the nodes
  for codegen and heuristics

- unified place where we can just adjust them for the template

# what

- inside get_mm_configs, return not the passed in kernel inputs,
  but allow the template heuristic to adjust them if necessary

- the default implementation right now just passes them back

this diff just adds the functionality, but does not exercise it
other than the default (passthrough)

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1205/1424] [ROCm] Use MI325 (gfx942) runners for binary smoke
 testing (#162044)

### Motivation

* MI250 Cirrascale runners are currently having network timeout leading to huge queueing of binary smoke test jobs:
<img width="483" height="133" alt="image" src="https://github.com/user-attachments/assets/17293002-78ad-4fc9-954f-ddd518bf0a43" />

* MI210 Hollywood runners (with runner names such as `pytorch-rocm-hw-*`) are not suitable for these jobs, because they seem to take much longer to download artifacts: https://github.com/pytorch/pytorch/pull/153287#issuecomment-2918420345 (this is why these jobs were specifically targeting Cirrascale runners). However, it doesn't seem like Cirrascale runners are necessarily doing much better either e.g. [this recent build](https://github.com/pytorch/pytorch/actions/runs/17332256791/job/49231006755).
* Moving to MI325 runners should address the stability part at least, while also reducing load on limited MI2xx runner capacity.
* However, I'm not sure if the MI325 runners will do any better on the artifact download part (this may need to be investigated more) cc @amdfaa

* Also removing `ciflow/binaries` and `ciflow/binaries_wheel` label/tag triggers for `generated-linux-binary-manywheel-rocm-main.yml` because we already trigger ROCm binary build/test jobs via these labels/tags in `generated-linux-binary-manywheel-nightly.yml`. And for developers who want to trigger ROCm binary build/test jobs on their PRs, they can use the `ciflow/rocm-mi300` label/tag as per this PR.

### TODOs (cc @amdfaa):
* Check that the workflow runs successfully on the MI325 runners in this PR. Note how long the test jobs take esp. the "Download Build Artifacts" step
* Once this PR is merged, clear the queue of jobs targeting `linux.rocm.gpu.mi250`

Subject: [PATCH 1206/1424] Prototype for building non-strict leak detector
 (#160456)

Summary:
Our strategy for detecting fake tensor leakage in non-strict for outside scope (side effects happening outside of model.forward) is:
1. We do gc.collect() before export and get the alive fake tensors
2. We dump the proxy to fake tensor map from make_fx tracer
3. We query gc again to get alive fake tensors
4. We take the delta between (1) and (3)
5. Filter out fake tensors that are:
    1. Associated with `TrackedFake` (input tracking thing in symbolic_shapes)
    2. Associated with `gm.meta`
6. Do ID match with the proxies and emit their stacktraces.

We rely on (https://github.com/pytorch/pytorch/pull/159923) for other sources of leakages such as:
1. We failed to proxy an operator (like param.data)
2. We cache some tensor in model.forward (https://github.com/pytorch/pytorch/issues/155114)

In general, we notice `gc.collect()` and query-ing gc for live objects are kinda slow. So we turn on this feature under env variable. We should document on export public facing documents that if you run into weird errors regarding fake tensors, they should look into turning on this env variable for further analysis.

+These functions are used to detect potential fake tensor leakage when using PT2 export.
+See NOTE [export non-strict fake tensor leak detection]
+
+There are some complications that made this logic overly complicated:
+1) Python 3.10 and Python 3.12 have different ways of implementing referrer so
+   we need to account for whether it is ref.__dict__ or the real ref object
+
+2) There are some internal PT2 references to fake tensors like `TrackedFake`
+3) closures, generators, and bound methods can hold fake tensors.
+4) global object can hold onto a fake tensor
+
+In general, these utils are our last resort to detect fake tensors. if the leak happens
+within the model attributes, we have a separate mechanism to detect. This tool relies a bit
+on garbage collector internal details, so I think it is unsafe to turn on by default, hence
+this tool should be used as debugging tool.

Subject: [PATCH 1207/1424] [pt2e] Avoid getting model device once per node
 (#159901)

**Summary:** Previously, we call `assert_and_get_unqiue_device` once per node in both prepare and convert. This is expensive and unnecessary since the model device is the same across all nodes, so we should just call this once in the beginning and reuse the same model device across all the nodes.

**Test Plan:**
python test/test_quantization.py -k TestQuantizePT2E

Fixes #153326

Minimal code to reproduce error:
```
import torch

tensor = torch.tensor([])

torch.choose_qparams_optimized(
    tensor,
    0,
    200,
    0.16,
    8
)
```

Previous Output:
`Segmentation fault`

Now Output:
```
Traceback (most recent call last):
  File "/home/amaitra/work/tests/issue_153326.py", line 5, in <module>
    torch.choose_qparams_optimized(
RuntimeError: input tensor is empty and has no data
```

Caused because `const float* input_row =input_tensor.const_data_ptr<float>();` becomes null

Subject: [PATCH 1215/1424] [ROCm] Bump AOTriton to 0.11b (#161754)

Notable new features/optimizations for SDPA operators on AMD systems from AOTriton 0.11b:

* Invoke AITER Assembly kernels on gfx942/gfx950 when inputs meet requirements
  - AITER ASM kernels deliver over 500TFLOPS training performance. See
    [AOTriton 0.11b Release Page](https://github.com/ROCm/aotriton/releases/tag/0.11b) for more
    details.
* Now returns natural based `logsumexp` tensor, matching CUDA's behavior
  - PR #156903 is reverted in this PR as well since it is not needed anymore.
* Enables `CausalVariant.LOWER_RIGHT`

The build system changes drastically along with new packaging scheme of
AOTriton 0.11

* AOTriton 0.11 packs GPU images separately from AOTriton runtime
* `aotriton.cmake` now selectively downloads image packs according to
  `PYTORCH_ROCM_ARCH`
* `aotriton.cmake` now only use pre-compiled runtime library that exactly
  matches the ROCM in the build environment. For PyTorch builds with ROCm
  versions not listed in the file, the build process will build AOTriton
  runtime without GPU images from source
  - This avoids any further ABI breaks like ROCM 6.4 -> 7.0
  - recursive git clone is disabled since building AOTriton runtime does not
    require submodules.

Bug fixes:

* Fix a kernel bug introduced when implementing SWA

Known Problems:

* gfx1100 target (Radeon RX 7000 Series) is moved back to experimental status
  due to accuracy issues. Triton compiler fixes are needed to restore the
  support status.
* Enabling TF32 tests affects accuracy for later non-TF32 tests on ROCM 7.0.
  This issue is under investigation.

Subject: [PATCH 1216/1424] Rename propagate_tensor_meta to make private again
 (#161744)

Rename the wrapper `propagate_tensor_meta` added in #161334 to make it clearly private, and rename the existing LRU function to accommodate.

Subject: [PATCH 1221/1424] [CI] viable strict upgrade: Explicitly name which
 linux binary wheels should block (#162100)

Reason:
rocm binary builds should not block viable strict upgrade.  It is queuing/canceled so viable strict is 1.2 days old

Tested by mangling the workflow file to get to the actual call of the python script `python ../test-infra/tools/scripts/fetch_latest_green_commit.py --required-checks '["pull", "trunk", "lint", "^linux-binary-manywheel$", "^linux-binary-libtorch-release$", "linux-aarch64"]' --viable-strict-branch viable/strict --main-branch master`, which I then ran locally where I have credentials.  It returned d64718503728001a1e78168fd7f2d4ff23e57285 which is green.  Without this change, it returns 5e5870e858f60ff4bf87d03f3592097e934a9580, which is pretty old

The other solution would have been to mark it as unstable I think

Side note, why is it master and how is it working like that

Subject: [PATCH 1226/1424] kill allow_complex_guards_as_runtime_asserts
 (#161794)

Summary:
[reland]
Since `allow_complex_guards_as_runtime_asserts` is now sync'd with `prefer_deferred_runtime_asserts_over_guards`, we can kill the former (especially since it was a export-only concept).

Test Plan:
updated tests

Rollback Plan:

Differential Revision: D81334984

Subject: [PATCH 1228/1424] [DCP][HuggingFace] Add Support for dequantization
 of SafeTensors checkpoints (#160682)

This PR introduces the QuantizedHuggingFaceReader component which enables the reading and dequantization of the quantized tensors in the SafeTensors checkpoint. Following capabilities are inrtoduced:
- Configuration the target DType and the block size.
- Multi threaded dequantization for efficiency

Test Plan:
buck test //caffe2/test/distributed/checkpoint\:test_quantized_hf_storage
```
Time elapsed: 2:34.1s
Tests finished: Pass 31. Fail 0. Fatal 0. Skip 0. Build failure 0
```

Subject: [PATCH 1229/1424] [dynamo] rename set_fullgraph to
 error_on_graph_break (#161739)

Renaming `set_fullgraph` to `error_on_graph_break` for now. There are no semantic differences yet. In a followup PR, we will introduce a new `torch.compile` option `error_on_graph_break` that has lower priority than `fullgraph` so that `fullgraph` really returns 1 graph.

I could keep `set_fullgraph` as a deprecated alias for `error_on_graph_break` for now, but I'm hoping that won't be necessary since it's still private API (there are no internal callsites yet, and there are no significant OSS callsites yet).

Subject: [PATCH 1231/1424] expose number of outputs in native runtime for
 unified runtime (#161723)

This is only user outputs which is what we want. Spoke to @zhxchen17 though and it seems like nativeRT might have some bugs on propogating updates to things like input mutation or buffer mutation though. Something to take a look at in a follow up.

Also I have no idea where the nativeRT tests are. Any pointers @zhxchen17  @SherlockNoMad

Subject: [PATCH 1232/1424] [Quant][Inductor][CPU] add qlinear int8-mixed-bf16
 patterns (#161486)

Summary:
Expand the patterns supported by qlinear weight prepack, Specifically, expand the linear patterns of int8-mixed-bf16 datatype to support the following two cases:
Case 1:
the `out_dtype` of `dequantize_per_tensor ` is `torch.float32`

    dq_per_tensor  dq_per_channel
         |               |
    to_bf16           to_bf16
         |               |
     OPT(reshape)     permute
            \          /
             addmm/mm
                    |
           OPT(reshape)

or

    dq_per_tensor  dq_per_channel
         |               |
    to_bf16           to_bf16
         |               |
       expand         permute
          \              |
                      expand
                       /
               bmm
                |
            OPT(add)

Case 2:
the `out_dtype` of `dequantize_per_tensor ` is `torch.bfloat16`

    dq_per_tensor  dq_per_channel
         |               |
                       to_bf16
                         |
     OPT(reshape)   permute
            \          /
             addmm/mm
                    |
           OPT(reshape)

or

    dq_per_tensor  dq_per_channel
         |                |
                        to_bf16
                          |
       expand          permute
          \               |
                        expand
                        /
               bmm
                |

Subject: [PATCH 1233/1424] [Quant][Inductor][CPU] add qconv int8-mixed-bf16
 patterns (#161487)

Summary:
Expand the patterns supported by qconv weight prepack, Specifically, expand the conv patterns of int8-mixed-bf16 datatype to support the following two cases:
Case 1:
the `out_dtype `of `dequantize_per_tensor  `is `torch.float32`

```
    dq_per_tensor  dq_per_channel
         |               |
    to_bf16           to_bf16
            \          /
             Conv2d
```

Case 2:
the `out_dtype `of `dequantize_per_tensor  `is `torch.bfloat16`

```
    dq_per_tensor  dq_per_channel
         \               |
                      to_bf16
                       /
             Conv2d
```

Subject: [PATCH 1238/1424] [pt] strip error messages in profile builds
 (#162076)

Summary: Profile builds should match production builds, and error messages result in large static initializers running. Omit them for profile builds too.

Test Plan:
Before:
```
$ buck build //xplat/caffe2:aten_native_cpuApple -c user.sandcastle_build_mode=profile --show-output
$ llvm-nm buck-out/v2/gen/fbsource/31fc3668aa0b4012/xplat/caffe2/__aten_native_cpuApple__/libaten_native_cpuApple.pic.a | grep ZN3c106detail12_str_wrapperIJPKcRKiS3_RKxS3_RKS3_S3_EE4callES9_S5_S9_S7_S9_S9_S9
0000000000003234 T __ZN3c106detail12_str_wrapperIJPKcRKiS3_RKxS3_RKS3_S3_EE4callES9_S5_S9_S7_S9_S9_S9_
```

After:
```
$ buck build //xplat/caffe2:aten_native_cpuApple -c user.sandcastle_build_mode=profile --show-output
$ llvm-nm buck-out/v2/gen/fbsource/31fc3668aa0b4012/xplat/caffe2/__aten_native_cpuApple__/libaten_native_cpuApple.pic.a | grep ZN3c106detail12_str_wrapperIJPKcRKiS3_RKxS3_RKS3_S3_EE4callES9_S5_S9_S7_S9_S9_S9
```

Subject: [PATCH 1241/1424] Contiguous subgraph decomposition (#161241)

## Summary

Adds a subgraph decomposition for addmm and mm that performs well on large `K` compared to `M` and `N`, and functions well as an alternative to `split-k` on AMD (transposed only), which does not support AMD currently.

## Background

On AMD (MI300x), for a matmul A * B, if B is non-contiguous, the resulting matmul is quite a bit slower.
For example:
```
  args[0]: TensorBox(StorageBox(
    InputBuffer(name='arg0_1', layout=FixedLayout('cuda:0', torch.float16, size=[1024, 178176], stride=[178176, 1]))
  ))
  args[1]: TensorBox(StorageBox(
    InputBuffer(name='arg1_1', layout=FixedLayout('cuda:0', torch.float16, size=[178176, 6144], stride=[1, 178176]))
  ))
```
is a lot slower than:
```
  args[0]: TensorBox(StorageBox(
    InputBuffer(name='arg0_1', layout=FixedLayout('cuda:0', torch.float16, size=[1024, 178176], stride=[178176, 1]))
  ))
  args[1]: TensorBox(StorageBox(
    InputBuffer(name='arg1_1', layout=FixedLayout('cuda:0', torch.float16, size=[178176, 6144], stride=[6144, 1]))
  ))
```
This PR adds a subgraph decomposition to test out whether making B contiguous is faster than just using the normal kernels.

## Data

I ran this on unique non-contiguous shapes from torchbench/huggingface and got these speedups:

## Results

The largest shape gain, `256,197951,512`, seemed to be driven by a case where the extern kernel is way faster than the best triton configs on the recursive autotune:

It seems to perform really well for high values of `K` vs `N` and `M`.

## Conclusion
Contiguous Subgraph Decompositionseems worthwhile for `mm` and `addmm`, but not `bmm`, and has a very large improvment on low `M`, low `N`, and high `K` shapes.

Subject: [PATCH 1243/1424] [DLPACK] Optimize toDLPack Conversion Speed
 (#162111)

Previously in gh-83069, the toDLPack converter introduces a normalization step that changes the strides to 1 when shape[i] == 1

This step, however, calls as_strided during toDLPack, and can slow down the toDLPack about 3x. This causes PyTorch's DLPack conversion to be around 0.6 us overhead per call from the < 0.2us.

This PR updates the logic by adding a need_normalize_strides check, to first confirm if the strides normalization is necessary. In most common cases, when the tensor is continguous, such normalization is not necessary.

We confirmed that having this additional step would recover the speed of toDLPack to below 0.2us and can help significantly speedup eager mode integration of DLPack with PyTorch.

If we detect that there is normalization needs, the older path will be invoked.

Fixes #162113

Subject: [PATCH 1244/1424] [ROCm] Enable USE_FBGEMM_GENAI (#160676)

Summary:
X-link: https://github.com/pytorch/FBGEMM/pull/4703

X-link: https://github.com/facebookresearch/FBGEMM/pull/1728

In this diff we enable the support for the new FBGEMM backed FP8 _scaled_grouped_mm on ROCm. For now we only enable support for `gfx942` as that is what we have thoroughly tested performance and correctness on.

Rollback Plan:

Differential Revision: D79564024

Test Plan:

Ensure builds with:
- `USE_FBGEMM_GENAI=1` and without gfx942
- `USE_FBGEMM_GENAI=1` and with gfx942
- `USE_FBGEMM_GENAI=1` and all current [`PYTORCH_ROCM_ARCH`](https://github.com/pytorch/pytorch/blob/9491d289b329e4ba4a9f5f5b1be7960671bb7840/.ci/docker/libtorch/build.sh#L48)

  warnings.warn(error_message
```

### After
```python

Subject: [PATCH 1249/1424] [inductor] Fix int64 from MutationOutput Buffer
 (#162020)

Summary:
When we have a user defined triton kernel, it marks the mutated outputs as `MutationOutput` with a NoneLayout. This MutationOutput may later be used as input to another inductor-generated triton kernel.

When we determine whether to use int32 or int64 for the inductor generated triton kernel, we need to look at the number of elements for all buffers involved. If one of the buffer is a MutationOutput, we should still consider it's number of elements, instead of skipping it.

To get a hint on the MutationOutput size, we look at the buffers corresponding to `mutation_names` in MutationOutput.

Test Plan:
```
buck run mode/opt  fbcode//caffe2/test/inductor:test_aot_inductor -- -r test_autotune_int64_user_defined_triton_kernel
```

Subject: [PATCH 1253/1424] [2/N]Port several test files under test/distributed
 to Intel GPU (#159473)

For https://github.com/pytorch/pytorch/issues/114850, we will port distributed tests to Intel GPU. This PR will work on some test files under test/distributed. We could enable Intel GPU with following methods and try the best to keep the original code styles:

- instantiate_device_type_tests()
- use "torch.accelerator.current_accelerator()" to determine the accelerator backend
- use requires_accelerator_dist_backend to allow both nccl and xccl test
- enabled XPU for some test path
- Change the hardcoded world_size according to device_count.
- Unify some common code under torch/testing/_internal for multiple backend, for example:
  Added xpu for Backend.backend_capability and dist.Backend.register_backend()

Subject: [PATCH 1254/1424] Revert "Make distributed modules importable even
 when backend not built (#159889)"

This reverts commit 4ae57d448c0a7d37e4cfd5c27d977fad2cef4051.

Reverted https://github.com/pytorch/pytorch/pull/159889 on behalf of https://github.com/jeanschmidt due to Failing internal tests, probably typechecks. See D81588399 ([comment](https://github.com/pytorch/pytorch/pull/159889#issuecomment-3253651785))

Subject: [PATCH 1255/1424] Relax tolerance for
 test_quick_baddbmm_cpu_complex64 (#152424)

On Zen 2 (AMD EPYC) and Intel Sapphire Rapids this fails with small differences when compiled with native targeted optimizations. I.e. it fails with `-march=znver2` but succeeds with `-march=znver1`.

I assume some operator fusing is being used by GCC. Small differences like using `vmovdqa` can be seen in the minimized code of the baddbmm kernel: https://godbolt.org/z/jsxMa91Wb

The greatest differences are consistent and the same on both CPU architectures:
```
Greatest absolute difference: 3.43852152582258e-05 at index (1, 2, 1) (up to 1e-05 allowed)
Greatest relative difference: 3.6034286949870875e-06 at index (1, 2, 1) (up to 1.3e-06 allowed)
```

Hence I assume this is in the expected tolerances  especially as `complex128` and all other types pass.

Subject: [PATCH 1257/1424] [CUDAGraph] add config to error on skipping
 cudagraph (#161862)

Many users want a config to force all cuda ops captured by cudagraph. When not possible, pt2 should error.

This PR adds `torch._inductor.triton.cudagraph_or_error` for that (default as False). Also added an environment variable `TORCHINDUCTOR_CUDAGRAPH_OR_ERROR` to control.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/161862

Subject: [PATCH 1260/1424] Keep default `CMAKE_PREFIX_PATH` in
 test_aot_inductor_package (#161907)

`CMAKE_PREFIX_PATH` is a list of paths used to find dependencies. The test overwrites that with a single path causing dependencies such as protobuf or Abseil not being found.

Instead prepend the path to the existing value.

This fixes a test failure:
> pytorch-v2.7.1/test/inductor/test_aot_inductor_package.py", line 242, in test_compile_after_package
>    self.assertTrue(so_path.exists())
> AssertionError: False is not true

Caused by:
```
/software/binutils/2.42-GCCcore-13.3.0/bin/ld: cannot find -labsl::utility: No such file or directory
/software/binutils/2.42-GCCcore-13.3.0/bin/ld: cannot find -labsl::variant: No such file or directory
collect2: error: ld returned 1 exit status

Subject: [PATCH 1264/1424] [ROCm] [CK] Composable Kernel integration for
 inductor backend (#158747)

This is a part of our effort for integrating Composable Kernel library for Inductor backend. Currently we have a submodule, but would prefer to have commit pin control over the library as with Triton. We intentionally avoid putting all installation logic in CI scripts to allow locally built versions to have this functionality.

The idea is to have CK as a pytorch dependency in pytorch 2.9 release to allow people to use it with inductor and AOT inductor and then gradually step away from submodule usage. Right now CK usage in SDPA/Gemm is tied to submodule files.

This PR is a remake of due to branch error: https://github.com/pytorch/pytorch/pull/156192

Subject: [PATCH 1267/1424] [dynamo] change error_on_graph_break/fullgraph
 semantics (#161747)

This PR implements the semantics change to `torch._dynamo.error_on_graph_break`:
- ~`torch.compile` now has a new `error_on_graph_break` kwarg that serves as a lower-priority toggle for erroring/continuing on graph breaks~
- `error_on_graph_break` is a new internal `torch.compile `setting that is lower-priority than `fullgraph`. It allows the user to toggle erroring/continuing on graph breaks.
- `error_on_graph_break` does nothing when `fullgraph=True`
- `error_on_graph_break` does NOT guarantee a single graph

Followup [DONE]: need to change the programming model docs to reflect the 3 graph break modes for compilation:
- `fullgraph=True`: enforce one graph, no graph breaks, cannot be toggled
- `fullgraph=False, error_on_graph_break=True`: errors on graph breaks, latter can be toggled during compile time
- `fullgraph=False, error_on_graph_break=False`: resumes tracing on graph breaks, latter can be toggled during compile time

+
+# Toggling `error_on_graph_break`
+
+**Summary:**
+
+- When `fullgraph=False`, we can use `torch._dynamo.error_on_graph_break()` for more flexibility in
+  dealing with graph breaks.
+
+So far, we have introduced two ways in dealing with graph breaks in `torch.compile`:
+1. `fullgraph=True` errors on the first graph break and additionally guarantees that only one graph is traced from the code.
+2. `fullgraph=False` continues tracing even when encountering graph breaks.
+
+What if we want to disallow graph breaks for most of the code, but there are a few problematic functions where the graph breaks are hard to remove,
+and we are okay with having those graph breaks? We can use `torch._dynamo.error_on_graph_break()` to achieve this.
+
+`torch.compile` has an `error_on_graph_break` setting (initially set to `False`).
+If a graph break or compiler error occurs in code while `error_on_graph_break` is set to `False`, then `torch.compile` will attempt to continue compilation after the graph break/error.
+If `error_on_graph_break` is set to `True`, then `torch.compile` will abort compilation and propagate the error to user code.
+
+A significant difference between `error_on_graph_break=True` and `fullgraph=True` is that the former **does not guarantee that a single graph will be captured**.
+`error_on_graph_break` **can be arbitrarily toggled during compile time** by using the `torch._dynamo.error_on_graph_break()` context manager/decorator.
+In comparison, once `fullgraph` is set to `True`, it cannot be set back to `False`.
+Finally, `error_on_graph_break` has lower precedence than `fullgraph` - `error_on_graph_break` only takes effect when `fullgraph=False`.
+
+
+## `error_on_graph_break(False)` example
+
+```{code-cell}
+@torch._dynamo.error_on_graph_break(False)
+def code_with_a_difficult_graph_break(x):
+    x = x + 1
+    torch._dynamo.graph_break()
+    return x + 2
+
+def inner(x):
+    return code_with_a_difficult_graph_break(x)
+
+# NOTE: fullgraph=False
+@torch._dynamo.error_on_graph_break(True)
+@torch.compile
+def fn(x):
+    return inner(x)
+
+# No error, but there is a graph break
+fn(torch.randn(3))
+```
+
+Using `error_on_graph_break(False)` under `error_on_graph_break(True)` is helpful for when we want to minimize graph breaks (i.e. follow the `fullgraph=True` programming model),
+but there are some sections of code with non-performance-critical graph breaks that are difficult to work around.
+
+`error_on_graph_break()` can be used as a context manager as well:
+
+```{code-cell}
+# NOTE: fullgraph=False
+@torch._dynamo.error_on_graph_break(True)
+@torch.compile
+def fn(x):
+    x = x + 1
+    with torch._dynamo.error_on_graph_break(False):
+        torch._dynamo.graph_break()  # no error
+    return x + 2
+
+# No error, but there is a graph break
+fn(torch.randn(3))
+```
+
+You can use monkey patching to toggle `error_on_graph_break` for code where you cannot edit the source (e.g. framework code):
+
+```{code-cell}
+class ThirdPartyModule(torch.nn.Module):
+    def forward(self, x):
+        x = x + 1
+        torch._dynamo.graph_break()
+        return x + 2
+
+tp_mod = ThirdPartyModule()
+tp_mod.forward = torch._dynamo.error_on_graph_break(False)(tp_mod.forward)
+
+@torch._dynamo.error_on_graph_break(True)
+@torch.compile
+def fn(x):
+    return tp_mod.forward(x)
+
+# No error, but there is a graph break
+fn(torch.randn(3))
+```
+
+## `error_on_graph_break(True)` example
+
+```{code-cell}
+@torch._dynamo.error_on_graph_break(True)
+def inner2(x):
+    x = x + 1
+    torch._dynamo.graph_break()  # error
+    return x + 2
+
+def inner(x):
+    return inner2(x)
+
+# fullgraph=False, error_on_graph_break=False
+@torch.compile
+def fn(x):
+    x = x + 4
+    torch._dynamo.graph_break()  # no error
+    return inner(x)
+
+try:
+    fn(torch.randn(3))
+except Exception as e:
+    print(e)
+```
+
+Using `error_on_graph_break(True)` under `error_on_graph_break(False)` is helpful for when we want to use `torch.compile` flexibly (i.e. follow the `fullgraph=False` programming model),
+but there are some sections of the code that are performance-critical and we want to ensure that those sections do not contain graph breaks.
+
+## `error_on_graph_break` nesting behavior
+
+`torch._dynamo.error_on_graph_break()` affects the `error_on_graph_break` setting of nested calls as well:
+
+```{code-cell}
+def inner(x):
+    x = x + 1
+    torch._dynamo.graph_break()
+    return x + 2
+
+def inner2(x):
+    with torch._dynamo.error_on_graph_break(False):
+        return inner(x)
+
+@torch._dynamo.error_on_graph_break(True)
+@torch.compile
+def fn(x):
+    return inner2(x)
+
+# no error
+fn(torch.randn(3))
+```
+
+`torch._dynamo.error_on_graph_break()` can be used under another `torch._dynamo.error_on_graph_break()` region:
+
+```{code-cell}
+def inner(x):
+    x = x + 1
+    with torch._dynamo.error_on_graph_break(False):
+        torch._dynamo.graph_break()
+    return x + 2
+
+def inner2(x):
+    with torch._dynamo.error_on_graph_break(True):
+        return inner(x)
+
+@torch.compile
+def fn(x):
+    return inner2(x)
+
+# no error
+fn(torch.randn(3))
+```
+
+## Interaction with `fullgraph`
+
+`fullgraph=True` takes higher precedence than `error_on_graph_break`:
+
+
+```{code-cell}
+@torch._dynamo.error_on_graph_break(False)
+def inner(x):
+    x = x + 1
+    torch._dynamo.graph_break()
+    return x + 2
+
+@torch.compile(fullgraph=True)
+def fn(x):
+    return inner(x)
+
+try:
+    fn(torch.randn(3))
+except Exception as e:
+    print(e)
+```
+
+`fullgraph=True` cannot be toggled back to `fullgraph=False`:
+
+```{code-cell}
+@torch.compile(fullgraph=False)
+def inner(x):
+    x = x + 1
+    torch._dynamo.graph_break()
+    return x + 2
+
+@torch.compile(fullgraph=True)
+def fn(x):
+    return inner(x)
+
+try:
+    fn(torch.randn(3))
+except Exception as e:
+    print(e)
+```
+
+```{code-cell}
+@torch.compile(fullgraph=True)
+def inner(x):
+    x = x + 1
+    torch._dynamo.graph_break()
+    return x + 2
+
+@torch.compile(fullgraph=False)
+def fn(x):
+    return inner(x)
+
+try:
+    fn(torch.randn(3))
+except Exception as e:
+    print(e)
+```
+
+## Summary of `fullgraph=True/False` vs `error_on_graph_break`
+
+Here is a table summarizing the differences between `fullgraph=True/False` and `error_on_graph_break`:
+
+|  | `error_on_graph_break=True` | `error_on_graph_break=False` (default) |
+| --- | --- | --- |
+| `fullgraph=True` | Graph breaks result in errors. Only the first graph break will be reported. **One graph guarantee.**<br><br>`fullgraph` cannot be toggled to `False`. `error_on_graph_break` has no effect.<br><br>User code must be fully compatible with `torch.compile`.

Subject: [PATCH 1268/1424] [CUDA] Reuse blocks with record_stream during CUDA
 Graph capture in the CUDACachingAllocator (#158352)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Introduction

During CUDA Graph capture, the CUDA caching allocator currently defers reclaiming blocks until capture ends. This is because CUDA forbids querying events recorded during capture (the CUDA operation is not executed during the capture stage), so the allocator cannot use its normal event-based logic. However, capture records an DAG (we call it **capturing graph**) of work. We can use the capturing graph to determine when a block’s old lifetime is fully before future work, and safely reuse it within the same capture.

This PR adds an experimental flag `graph_capture_record_stream_reuse: True|False (default: False)`. When enabled, the allocator inserts lightweight free markers and uses capture ordering to decide if a freed block is safe to reuse during capture. If the proof cannot be established, we fall back to the existing post-capture path.

## Terms

* **Free marker**: A capture-legal no-op (created with `cudaGraphAddEmptyNode`) inserted after the last captured use of the block on each stream that used it.
* **Terminal**: The set of the lastest operations of the stream (or the capturing graph). Any newly captured op on that stream will attach after all nodes in this set. For a stream currently capturing, it is the set of nodes returned in `dependencies_out` by `cudaStreamGetCaptureInfo`.

## When can we reuse a block during capture?

### Strong Rule (Graph-Wide Safety)

This rule provides a universal guarantee that a block is safe for reuse by any stream in the graph.

> A block is safe to reuse if every free marker is a predecessor of every terminal of all active streams in the graph.

Why it's safe:

This rule establishes a strict global ordering. Since any new operation on any stream must be appended after that stream's terminals, this condition guarantees that the block's new lifetime begins only after its old lifetime has completely ended everywhere. This prevents lifetime overlaps when the graph is replayed, ensuring correctness.

### Per-stream Rule (A Practical Optimization)

The strong rule, while safe, is often unnecessarily restrictive. The `DeviceCachingAllocator` introduces a crucial constraint that allows for a simpler check.

In `DeviceCachingAllocator`, `get_free_block` only returns blocks whose `block->stream == p.stream()`. In other words, we never reuse a block on a stream different from the allocation stream. This means we don't need to verify safety across the entire graph. We only need to confirm that the block is safe to reuse from the perspective of its own allocation stream.

> Reuse a block for allocations on stream S if every free marker is a predecessor of every node in the terminal set of S.

In short, a block is considered **reusable** on stream S as long as all marker marking it "free" are guaranteed to complete before any new work that might need it on stream S begins.

## Implementation

* On `free(block)` during capture
  * For each stream in `block->stream_uses` and the allocation stream, insert a free marker (empty node) and make it that stream’s tail.
  * If we cannot place markers for all such streams (for example, a stream is not in capture), defer to the post-capture path.
  * Otherwise, store the marker handles and keep the block in the capture-private structures.
* On `allocate(stream)` during capture (attempt per-stream reclaim)
  * Query the allocation stream S’s terminal via `cudaStreamGetCaptureInfo`.
  * For each deferred block, check whether it is allocated on this stream, and each of its free markers is a predecessor of the terminal.
    * If yes, hand the block to S for immediate reuse within the same capture.
    * If no, keep it deferred; it will be reconsidered as capture progresses and S’s terminal advances.
* On capture end
  * Any still-deferred blocks follow the existing post-capture reclamation (event insertion/polling). External behavior remains unchanged if we cannot prove safety during capture.

## Examples (2 streams)

<img width="641" height="801" alt="pytorch-remove-cudagraph-defer-reclaiming (6)" src="https://github.com/user-attachments/assets/41adc835-d448-483b-99ba-b4341cb7d2a2" />

* Case 0 — Unsafe
The two frees are not ordered with respect to each other. For stream 1, the other stream’s free marker does not precede this stream’s terminal, so the per-stream condition fails.
Counterexample intuition for the unsafe setups: imagine `f2(x)` runs for a long time. If DeviceCachingAllocator reused block `x` on a stream whose terminal is not ordered after the free markers, the new lifetime could overlap the old one on replay, risking use-after-free or data corruption. The per-stream rule prevents exactly this.
* Case 1 — Reusable on stream 1
Stream 1’s terminal is after both frees, so every free marker precedes stream 1’s terminal. The block is reusable for allocations on stream 1.
* Case 2 — Not reusable on stream 2, but this cannot occur in `DeviceCachingAllocator`
This depicts reusing the block on stream 2 while stream 1’s free is not yet ordered before stream 2’s terminal. Though the block is not safe to reuse on stream 2, DeviceCachingAllocator will not choose that block for stream 2 anyway: `get_free_block` rejects blocks whose `stream != p.stream()`. So this case is unreachable.
* Case 3 — Safe (strong rule holds)
In this scenario, the terminal nodes of all streams are positioned after the block's free markers, satisfying the strong rule. This guarantees the block is safe for reuse by any stream in the capturing graph. However, since `DeviceCachingAllocator ` only reuses a block on its original allocation stream, verifying this strong condition is unnecessary. We only need to ensure the per-stream rule is met for the specific stream requesting the block.
* Case 4 — Freeing after a join
See the note below.

## Edge Case: Freeing after a join

Our current dependency tracking has a limitation in scenarios where a block is freed after a stream join, see @galv's [comments here](https://github.com/pytorch/pytorch/pull/158352#pullrequestreview-3112565198)).

In the case 4, we have a missed opportunity. Because the block's usage is not explicitly marked, we cannot determine that the block's actual last use may have occurred much earlier, long before the join. Then, we must wait for the subsequent join before the block can be reused.

## Thanks
Thanks to @galv for his great idea around graph parsing and empty nodes.

Subject: [PATCH 1271/1424] create torch._grouped_mm fallback path with for
 loops / bmm (#161407)

Summary:

Creates a fallback path for `torch._grouped_mm`, using the naive for
loop implementation (or bmm).

For the sake of keeping the PR small, this PR only enables SM80+ (CUDA
capability 8.0 and up), since I am testing this on an A100 machine. In
future PRs, we can increase the coverage of the fallback to:

Subject: [PATCH 1272/1424] move `_grouped_mm` fallback to composite explicit
 autograd (#161717)

Summary:

Moves the `torch._grouped_mm` fallback from cuda-only code to a place
where it can be used by multiple backends. Specifically:
1. make the fallback path and util functions reusable and move them to
   `ATen/native/GroupedMMUtils.h`
2. register a backend-agnostic kernel to composite explicit autograd key
3. refactor the grouped_mm tests to their own test case and enable CPU

At the end of this PR, here is the support matrix:
* CUDA SM90+: fast path with test coverage (no change)
* CUDA SM80+: fallback with test coverage (no change)
* CPU: fallback works, but without test coverage (new in this PR)
* other SM versions and other backends: will probably already work, but
  let's leave this to future PRs
* float32/float16: will probably already work, but let's leave this to
  future PRs

Test Plan:

```bash
pytest test/test_matmul_cuda.py -s -k test_grouped_gemm -x
```

Subject: [PATCH 1273/1424] enable float32 and float16 in `torch._grouped_mm`
 fallback (#162059)

Summary:

Enables `torch.float32` and `torch.float16` options in
`torch._grouped_mm`. Note that the fast path is only enabled if `mat_a`,
`mat_b`, and `out_dtype` are `torch.bfloat16`.

Saving for future PRs:
1. enabling testing on more platforms
2. supporting out_dtype != mat_a.dtype
3. opinfo
4. better compile support

Test Plan:

```bash
// on A100 and H100
pytest test/test_matmul_cuda.py -s -k test_grouped_gemm -x
// on H100
pytest test/test_matmul_cuda.py -s -k test_scaled_grouped_gemm -x
```

Subject: [PATCH 1275/1424] export: add explicit decomposition for
 aten.expand_copy and unit test (#161688)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #161080
torch.export.export fails with TypeError: expand() got an unexpected keyword argument 'implicit' when calling torch.expand_copy(..., implicit=True). This happened because expand_copy = _make_copy_from_view(aten.expand) register aten. expand as the decomposition path for aten.expand_copy, which doesn’t accept the implicit argument.

I have added an explicit a decomposition for aten.expand_copy in torch/_decomp/decompositions.py to ignore the implicit argument, and a simple unit test to demonstrate the bug being fixed.

…h.is_complex.

The PR proposes adding a simple, self-explanatory example to the documentation page. The example demonstrates the function's output for tensors with various data types, showing both True and False return values.

Fixes #161859

Subject: [PATCH 1285/1424] Fix Arm64 OSS pytorch build with FBGEMM (#161527)

Summary:
X-link: https://github.com/pytorch/FBGEMM/pull/4775

Without this change, Arm64 OSS pytorch build with FBGEMM failed with the following error.
Undefined symbols for architecture arm64:
  "fbgemm::FindMinMax(float const*, float*, float*, long long)", referenced from:
      at::native::fbgemm_linear_int8_weight_fp32_activation(at::Tensor const&, at::Tensor const&, at::Tensor const&, at::Tensor const&, c10::Scalar const&, c10::Scalar const&, at::Tensor const&) in QuantizedLinear.cpp.o
      at::native::fbgemm_linear_quantize_weight(at::Tensor const&) in QuantizedLinear.cpp.o
      PackedConvWeight<2>::apply_dynamic(at::Tensor const&, bool) in qconv_dynamic.cpp.o
      PackedConvWeight<3>::apply_dynamic(at::Tensor const&, bool) in qconv_dynamic.cpp.o
      at::Tensor PackedLinearWeight::apply_dynamic_impl<false>(at::Tensor, bool) in qlinear_dynamic.cpp.o
      at::Tensor PackedLinearWeight::apply_dynamic_impl<true>(at::Tensor, bool) in qlinear_dynamic.cpp.o
ld: symbol(s) not found for architecture arm64

This change fixed the issue by moving FindMinMax's implementation from QuantUtilsAvx2.cc to QuantUtils.cc. FindMinMax is a platform-agnostic function with AVX2-specific optimizations so conceptually it can be put in QuantUtils.cc.

Test Plan:
With this change, Arm64 OSS pytorch built successfully with FBGEMM enabled.

Rollback Plan:

Subject: [PATCH 1286/1424] Revert "[nativert] triton runtime implementation
 (#161798)"

This reverts commit 3dde5d7f9bf80dd6623a712bc429e9e4302464b5.

Reverted https://github.com/pytorch/pytorch/pull/161798 on behalf of https://github.com/jeanschmidt due to introducing linting failures ([comment](https://github.com/pytorch/pytorch/pull/161798#issuecomment-3255412085))

Subject: [PATCH 1287/1424] Make distributed modules importable even when
 backend not built (#159889)

This PR is greatly simplified now that it stacked on top of a PR that builds with distributed always. We only need to stub functions that may not be defined due to a backend not being enabled.

Subject: [PATCH 1294/1424] fix incorrect interaction between DDPOptimizer and
 donated buffers (#160745)

This should fix https://x.com/wightmanr/status/1953147089518772254?t=ng_R4t0-tRhO_qQE8NqOhw&s=19. Still working on adding a reasonable test.

You can see more of a description of the problem in the code comments. But the TLDR is that:

* When using DDPOptimizer, we partition the graph and compile several subgraphs. So 1 dynamo graphs becomes N AOT/inductor artifacts
* We have some existing logic to stash graph metadata (`fw_metadata`) in dynamo's TracingContext. When using DDPOptimizer, we generate one `fw_metadata` per **AOT** graph, and we stash it on the 1 TracingContext from dynamo. So we end up clobbering the `fw_metadata` for graph i-1 when AOT and inductor start compiling graph i
* This is normally ok, but it becomes a problem if inductor ever wants to read from this `fw_metadata` during **backward compilation**. Why? We (by default) compile the backwards lazily. So when using DDPOptimizer, we will compile backward graph N, then bw graph N-1, etc. But... at the time that we have stated compiling bw graph N-1, its corresponding fw_metadata has already been clobbered! So we end up reusing graph N's metadata for all of our backward graph compilations. With donated buffer metadata, that means we end up donated and writing into incorrect input buffers

The fix that I added was to add more dedicated DDPOptimizer metadata into the TracingContext, so we can properly switch between these N different `fw_metadata` objects in the backward.

Subject: [PATCH 1295/1424] Fix memory leak in AOTI when calling
 `aoti_torch_as_strided` (#162118)

Summary:
Fix memory leak in AOTI when calling `aoti_torch_as_strided`

If you have something like `AtenTensorHandle buf_handle`; and you allocated memory to it, you have to make it a `RAIIAtenTensorHandle` to release the ownership. Otherwise you have leaked the memory because even when the program ends, there's still a pointer pointing to the underlying storage of `buf_handle_restrided`, and the storage is never freed.

Test Plan:
```
buck run fbcode//mode/dev-nosan fbcode//caffe2/test/inductor:test_aot_inductor -- -r test_pad_non_zero_memory_leak
```

Also verified by looking at `print(f"Allocated memory: {torch.cuda.memory_allocated() / 1024 ** 2:.2f} MB")`

Subject: [PATCH 1304/1424] Add new parameter for gen_pyi.py to make it more
 configureable. (#161772)

This is a reposting of PR #128519.
This change is important to how we maintain PyTorch at Google.

From the previous PR:
"
This will make the script more flexible for the directory where it is executed.
...
We plan to use the deprecated_yaml from a blaze genrule that invokes pyi.py. As the input to the pyi.py, genrule requires the input file to be explicitly listed out. When we feed the value of tools/autograd/deprecated.yaml to genrule, it failed to resolve since tools/autograd is a package from blaze perspective. Any file under a blaze package will a proper blaze target to be access.
"

Subject: [PATCH 1306/1424] Allow for using a dedicated binary for the torch
 subproc pool. (#162093)

Summary:
The binary torch is running inside of can be larger than needed and in certain
situations, this can cause a loss of memory.

Test Plan:
We've manually run tests via
```
TORCHINDUCTOR_FORCE_DISABLE_CACHES=1 TORCHINDUCTOR_WORKER_SUPPRESS_LOGGING=0
make mc8-train-publish-cint-datafm-toy -C
minimal_viable_ai/models/ifr_mtml/main_v1/ 2>&1 | tee ~/run_out
```
and overriding the binary used to be the built fbpkg in /packages.

We've also kicked off manual runs at
```
fire-feid-20250903-1051-ae8c6827
```

Which do show the binary running -  https://fburl.com/scuba/procprint/e6lwv32m

Rollback Plan:
steps:
  - jk.update:
      jk: pytorch/compiler:subproc_worker_binary
      constant_bool: null
      consistent_pass_rate: null
      fractional_host_rollout: null
      sampling_rate: null

Subject: [PATCH 1307/1424] [BE] [Inductor] Add Kernel name to all coor-desc
 tuning (#161409)

Summary: When running coordinate descent tuning the logging is difficult to parse if the results are parallelized at all. This includes the kernel name in each step so post-processing can unify the results, even if run in parallel.

Test Plan:
NFC. Just a logging change.

Rollback Plan:

Subject: [PATCH 1311/1424] [1/N] Port 5 _composable/fsdp distributed test
 cases to Intel GPU (#159118)

For https://github.com/pytorch/pytorch/issues/114850, we will port distributed tests to Intel GPU.
We could enable Intel GPU with following methods and try the best to keep the original code styles:

- use "torch.accelerator.current_accelerator()" to determine the accelerator backend
- enabled XPU for some test path
- skip some test cases which Intel GPU does not support

Subject: [PATCH 1313/1424] [ez][inductor] add a few outer dimension reduction
 cases for LOAF (#162028)

For the not able to fuse issue reported here: https://github.com/pytorch/pytorch/issues/93718 , LOAF can fuse the outer dimension softmax into a single kernel and brings 1.87x speedup for the example shape mentioned in the issue.

Pull Request resolved: https://github.com/pytorch/pytorch/pull/162028
Approved by: https://github.com/jansel, https://github.com/eellison

Subject: [PATCH 1315/1424] [DCP][Quantization] Fix for FP8 multiplication
 during dequantization (#162202)

Summary:
Weight vector needs to be upcasted since some FP8 formats (like Float8_e4m3fn) don't have CPU implementations in PyTorch. Reference: https://docs.pytorch.org/docs/stable/tensors.html#id13

We will use FP32 for the scale vector multiplication and convert to the target dtype.

Upcasting helps with the following:

1.  **Full CPU support**: `float32` has complete CPU kernel implementations for all operations
2.  **Numerical stability**: `float32` provides more precision during intermediate calculations
3.  **Compatibility**: Works across all devices (CPU/GPU) and PyTorch versions

Test Plan:
UTs

Rollback Plan:

Differential Revision: D81711093

Subject: [PATCH 1318/1424] [cuBLASLt][FP8] `cuBLASLt` appears to support
 float8 rowwise-scaling on H100 (#161305)

Following #157905 I think the macro around
```
  TORCH_INTERNAL_ASSERT(use_rowwise == false, "rowwise scaled_gemm not supported with blaslt");
```
was never updated and this would cause `float8` tests to fail. Also it appears the `Lt` accepts two inputs with `e4m3` and `e5m2` dtypes simultaneously, so removing that check here as well...

Subject: [PATCH 1323/1424] [inductor][contigous mm] mild refactor (#162075)

# why

- use the new heuristics logic better to handle kwargs

# what

- move all checks into the heuristics to yield a single choice or not
  choices if the decomposition should not be used
- fix `hip` device type, which should be `cuda`
- let heuristics handle the kwarg passing

# testing

Subject: [PATCH 1324/1424] [inductor] move scaled_mm input nodes logic
 (#161340)

# why

- a step towards a unified interface for all choices, where any
  adjustment to nodes (e.g. unsqueezing) happens as part of
  choice specific preprocessing, behind a common point

# what

- move the unsqueeze logic for triton nodes for scaled_mm inside
  the new hookup for adjusting the kernel inputs for template
  heuristics

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v -k "scale"
```

Subject: [PATCH 1325/1424] [inductor][ez] add template/externchoice uid
 (#161341)

# why

- to have a central registry of templates/externkernelchoice
  to match them to heuristics etc, they need unique names
- mm is both the triton template name and the aten_mm name

# what

- add a uid() to KernelTemplate/ExternKernelChoice that returns name
- override in ExternKernel to prepend "aten::"
- override in TritonTemplate to prepend "triton::"

This id is just use to find template heuristics, so it has no other
impact

# testing

```

Subject: [PATCH 1326/1424] [inductor][aten] treat like a template in GEMMs
 (#161342)

# why

- central point to analyze and override all generated choices

# what

- add a pseudo heuristic for aten that just yields a single, empty
  kwargs
- add a pseudo heuristic with the bias_addmm logic for it
- add an addmm specific heuristic that yields a single choice, but
  also expands it with alpha and beta kwargs

- replace all the aten.bind calls with V.choices.get_mm_configs
  using the now matching API for aten

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1327/1424] [inductor][ez] pass template rather than
 template.uid (#161343)

# why

- simpler interface
- enables future of extracting more things out of the template e.g. a
  hash

# what

V.choices.get_mm_configs now takes the whole template rather than just
the template.uid

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1328/1424] [inductor] move max-autotune logic inside
 V.choices.get_mm_configs (#161344)

# why

- heuristics providers know decide whether to (or which choices to add)
  in the max-autotune case
- enables an eventual override point to gracefully fallback to the
  standard behavior

# what

- max-autotune is determined inside V.choices.get_mm_configs
  because it's mm only right now, we can just do
  `config.max_autotune or config.max_autotune_gemm`
  a TODO indicates that this can change in the future when this
  expands to more templates

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1329/1424] [inductor][ez] return choicecallers directly
 (#161345)

# why

- remove repeat patterns
- we have everything to make the choicecallers
  - templates
  - input_nodes
  - layouts
  - all the kwargs

# what

- yield a choicecaller directly from V.choices.get_mm_configs

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v

Subject: [PATCH 1330/1424] [inductor] V.choice.get_mm_configs takes a stack of
 templates (#161346)

# why

- enables us to just gather relevant templates and get all
  choices at once
- that in turns allows us to make op wide override decisions

# what

- V.choice.get_mm_configs takes a stack of templates
- all callsites just provide a stack of size 1 right now
  but do not merge everything yet (other features pending)

# testing

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1331/1424] [inductor] add kernel template choice (ktc)
 (#161347)

# why

- gather everything up to make choices, without running
  potentially expensive generators
- enables overrides where we toss the entire list of configs
  from inductor, without having to enumrate it (expensive)

# what

- add a holding class that just gets all the components necessary
  to generate a ChoiceCaller
- use that class to generate ChoiceCallers
- this does not (yet) add the override function, but just prepares
  the scene

```
python3 -bb -m pytest test/inductor/test_max_autotune.py -v
```

Subject: [PATCH 1332/1424] [inductor][ez] V.choices.get_mm_configs returns
 list of ChoiceCallers (#161348)

\# why

- every callsite just executes the generator on the spot
- previous pr adds the ability to add an override before expensive
  generators are executed, so we don't need this generator anymore

\# what

- rather than yielding the ChoiceCaller, just return the list of all
  valid ChoiceCallers

\# testing

```

Date: Thu, 4 Sep 2025 12:58:51 -0400
Subject: [PATCH 1340/1424] Make distributed modules importable even when
 backend not built (#159889)

This PR is greatly simplified now that it stacked on top of a PR that builds with distributed always. We only need to stub functions that may not be defined due to a backend not being enabled.

Subject: [PATCH 1342/1424] [cutlass backend] Add FP8 tests for multiple
 linears (#160782)

Adding a test that is closer to real use case. Thanks @mlazos for fixing a few issues so this test works for most cases.

We still have to skip the AOTI and dynamic case due to accuracy issues.

Subject: [PATCH 1344/1424] [C10d][Gloo] Enable complex datatype support in
 ProcessGroupGloo (#156633)

- Enable communication of tensors with Complex datatype in ProcessGroupGloo, similar to how ProcessGroupNCCL handles it.
- Move a function, which checks if Complex datatype is supported by a reduce operation, from ProcessGroupNCCL.cpp into a new file to be shared with ProcessGroupGloo.

Fixes #156632

Subject: [PATCH 1346/1424] Making batching rule for F.embedding DTensor-aware
 (#162117)

`vmap(F.embedding)(DTensor, DTensor)` was failing because F.embedding's
batching rule generates a new tensor via at::arange, at::arange
generates a regular tensor, and DTensor rightfully errors on mixed
DTensor-regular Tensor operations.

This PR fixes the problem by activating DTensor implicit replication on
just the at::arange and the subsequent add operation.

In order to accomplish this I move the DTensor implicit replication flag
to C++ (most batching rules are in C++).

Test Plan:
- new test

Subject: [PATCH 1348/1424] [DCP][Quantization] Fix the issue when scale vector
 is in a different SafeTensors file (#162214)

Summary: The current dequantization implementation assumes that the weight and scale tenors are in the same SafeTensors files. This diff fixes the issue to support the case when these could be in different files.

Test Plan:

Subject: [PATCH 1349/1424] [aot-precompile] default-filter global guards
 (#162090)

if the user doesn't provide their own guard filter fn, we should by default filter global guards.

Subject: [PATCH 1353/1424] Add return-max-scores to flex-attention (#161667)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Summary

### Update

API

```Py
class AuxRequest(NamedTuple):
    """Request which auxiliary outputs to compute from flex_attention.

    Each field is a boolean indicating whether that auxiliary output should be computed.
    """

    lse: bool = False
    max_scores: bool = False

class AuxOutput(NamedTuple):
    """Auxiliary outputs from flex_attention operation.

    Fields will be None if not requested, or contain the tensor if requested.
    """

    lse: Optional[Tensor] = None
    max_scores: Optional[Tensor] = None

  out_only = flex_attention(query, key, value, score_mod)
  out_max, aux_max = flex_attention(
      query,
      key,
      value,
      score_mod,
      return_aux=FlexAttentionAuxRequest(max_scores=True),
  )
  out_both, aux_both = flex_attention(
      query,
      key,
      value,
      score_mod,
      return_aux=FlexAttentionAuxRequest(lse=True, max_scores=True),
        )
```

Returns the max post mod scores from flex attention.

Not being able to break BC is kinda of annoying here since we end up with a combinatorial problem where if we need to add any more return vals we need to new kwargs that gate if they get returned by the function and need to support the 2**N additional args possible return groups.

Ideally there isn't much more we need to return, but we might want to think about how best to set this up for expansion in the future. I added kwarg only now

Maybe we make a `ExtraReturns` type kwarg that can grow and we don't need to keep adding new top level args.

We could also return a Struct that holds all the extra tensors and start deprecation cycle for logsumexp eventually returning just 1 `ExtraReturns` like struct with the tensors.

### Req Grad
I currently dont return a max_scores that supports backproping grads. I think this might be feasible  but since max is essentially 1 hot 	on the inputs and a reduction we would either need to save another `max_location` from the forward or find the max_score but also only apply to first occurence if there is multiple equivalent scores (need to check if thats we define for vanilla max op in torch).

For now no grad, we can re-visit if needed.

## Perf
I am going to disable for flex_decode. Since at least initially the motivation is for training. I also more hard than it should be to have ops return nuns or optional tensors, If return max is at the false, we should probably just create a tensor of size zero so that we don't slow down the hot path.

Subject: [PATCH 1355/1424] [dynamo] Graph break on on user-defined class in
 compiled region (#161670)

Currently, user-defined classes inside of a compiled frame will cause the whole
frame to be skipped by dynamo.  This change defers the Unsupported exception
until the __build_class__ builtin is actually called, which allows a graph break
to be inserted.  Fixes #161562

-  Explanation: Dynamo does not support tracing classes that are defined in the compiled region.
-  Hint: Move the class definition out of the compiled region.
-  Hint: It may be possible to write Dynamo tracing rules for this code. Please report an issue to PyTorch if you encounter this graph break often and it is causing performance issues.
+Attempted to call function marked as skipped
+  Explanation: Dynamo does not know how to trace the builtin `builtins.__build_class__.` This function is either a Python builtin (e.g. _warnings.warn) or a third-party C/C++ Python extension (perhaps created with pybind).
+  Hint: If it is a Python builtin, please file an issue on GitHub so the PyTorch team can add support for it and see the next case for a workaround.
+  Hint: If it is a third-party C/C++ Python extension, please either wrap it into a PyTorch-understood custom operator (see https://pytorch.org/tutorials/advanced/custom_ops_landing_page.html for more details) or, if it is traceable, use `torch.compiler.allow_in_graph`.

Subject: [PATCH 1359/1424] [inductor] estimate peak memory in codegen only
 when buffer reuse (#162300)

As titled, this PR ensures peak memory is estimated only when buffer reuse is enabled. Without this config, some nodes' successor nodes are eliminated from memory estimation after inductor bucketing, which can cause errors.

The original codegen peak memory estimation code is from this PR: https://github.com/pytorch/pytorch/pull/159530

+# Joint with descriptors
+
+Joint with descriptors is an experimental API for exporting a traced joint
+graph that supports all of torch.compile's features in full generality and,
+after processing, can be converted back into a differentiable callable that
+can be executed as normal.  For example, it is used to implement autoparallel,
+a system that takes a model and reshards inputs and parameters to make it
+a distributed SPMD program.

Subject: [PATCH 1366/1424] Fix `DeviceMesh._flatten` docstring example
 (#162277)

Fix the `DeviceMesh._flatten` docstring example of use. Alternative fix would be to replace `mesh_3d["dp", "cp"]` with `mesh_3d["cp", "tp"]`.

(I verified the fix using the `gloo` backend)

When running bazel build, we (Google) run into the following error.
The `-Wctad-maybe-unsupported` warning would be raised to an error and break the build in certain cases.
So, we propose to suppress the warning to make the build with bazel more smooth.

This is the error message we got:

-Attempted to call function marked as skipped
-  Explanation: Dynamo does not know how to trace the builtin `builtins.__build_class__.` This function is either a Python builtin (e.g. _warnings.warn) or a third-party C/C++ Python extension (perhaps created with pybind).
-  Hint: If it is a Python builtin, please file an issue on GitHub so the PyTorch team can add support for it and see the next case for a workaround.
-  Hint: If it is a third-party C/C++ Python extension, please either wrap it into a PyTorch-understood custom operator (see https://pytorch.org/tutorials/advanced/custom_ops_landing_page.html for more details) or, if it is traceable, use `torch.compiler.allow_in_graph`.
+LOAD_BUILD_CLASS bytecode not supported
+  Explanation: Dynamo does not support tracing classes that are defined in the compiled region.
+  Hint: Move the class definition out of the compiled region.

Subject: [PATCH 1373/1424] [AOTI-FX] Support registering custom FX backends
 (#162317)

# Feature
Currently, `torch._inductor.compile_aot` always uses the `WrapperFxCodegen` class. In contrast, Python and C++ codegen allow users to register custom backends. This PR brings that feature to FX codegen.

# Test plan
Added a CI test registering a custom FX backend.

Subject: [PATCH 1375/1424] MXFP8 grouped GEMM support for
 torch._scaled_grouped_mm + submodule bump (#162209)

## Summary
- We just landed 2d-2d support for mxfp8 grouped gemm in FBGEMM: https://github.com/pytorch/FBGEMM/pull/4816
- This is needed for backward pass of mxfp8 MoE training with grouped gemms
- Changes:
    - Add dispatching + input validation for mxfp8 grouped gemm in `torch._scaled_grouped_mm`
    - Add meta registration input validation for mxfp8 grouped gemm, for composability with compile
    - Add unit tests exercising torch._scaled_grouped_mm with mxfp8 inputs
    - Bump FBGEMM third party submodule to include:
          - https://github.com/pytorch/FBGEMM/pull/4816
          - https://github.com/pytorch/FBGEMM/pull/4820
          - https://github.com/pytorch/FBGEMM/pull/4821
          - https://github.com/pytorch/FBGEMM/pull/4823

#### How fbgemm dependency was bumped
Documenting this since I haven't found it documented elsewhere:
- `cd ~/pytorch/third_party/fbgemm`
- `git fetch`
- `git checkout <hash>`
- `cd ~/pytorch`
- `git add third_party/fbgemm`

## Test plan

#### Test build
```
USE_FBGEMM_GENAI=1 python -m pip install --no-build-isolation -v -e .
...
Successfully installed torch-2.9.0a0+gitf5070f3
```
[full build log](https://www.internalfb.com/phabricator/paste/view/P1933787581)

#### Unit tests
```

Subject: [PATCH 1376/1424] [3/N] Enable 6 fsdp test on Intel GPU (#161601)

For https://github.com/pytorch/pytorch/issues/114850, we will port distributed tests to Intel GPU. This PR is created base on PR https://github.com/pytorch/pytorch/pull/158533 and https://github.com/pytorch/pytorch/pull/159473 and will work on some test files under test/distributed/fsdp. We could enable Intel GPU with following methods and try the best to keep the original code styles in this PR:

1. add allow_xpu=True in instantiate_device_type_tests() if needed.
2. use "torch.accelerator.current_accelerator()" to determine the accelerator backend

3. enabled XPU for some test path

Subject: [PATCH 1377/1424] New export implementation with flat inp/out
 (#162167)

This is my first attempt of building new export API. The main thing it addresses is correctly getting input and output relations. Subsequent diffs willl add functionality for dynamic shapes, nn_module_stack etc.

Subject: [PATCH 1379/1424] [inductor] rename deps during refreshing (#162303)

Skiping renaming cause wrong dependencies when mutations are involved.

Test:

CUDA_VISIBLE_DEVICES=4,5,6 TORCHINDUCTOR_LOOP_ORDERING_AFTER_FUSION=1 python test/distributed/test_compute_comm_reordering.py TestComputeCommReorderingMultiProc.test_reorder_compute_for_overlap

Both all-reduce and wait-tensor ir node contains a MutationBuffer for this test.

Subject: [PATCH 1380/1424] NLLLoss: validate target is 0D when input is 1D
 (#161412)

Add a shape check in nll_loss_forward to error out when both input and target are 1D. Added a unit test to cover the incompatible 1D/1D case.

Fixes #157420

+# We can compute gx using chain rule:

+#     gx = gy0 * bw(y0, x),
+#
+# where gy0 denotes the graident of loss with respect to y0, and bw(y0, x) denotes the graident of y0 with
+# respect to x. Note that bw can be computed from forward body_fn easily using torch.autograd.grad.
+# We could substitute the unknowns gy0, gy1, ..., with chain rule until gy4:
+#
+#     gx = gy1 * bw(y1, y0) * bw(y0, x)
+#        = gy2 * bw(y2, y1) * bw(y1, y0) * bw(y0, x)

+#
+# since gy4 is the graient of the final output, which is given as the backward input, we've got a formula
+# to compute gx. A abbr for the formula is: gy4 * bw43210x
+#
+# In a similar way, we can compute g_additional_inputs using chain rule:
+#
+# g_additional_inputs = gy0 * bw(y0, addi) + gy1 * bw(y1, addi) + gy2 * bw(y2, addi) + ... + gy4 * bw(y4, addi)
+#
+# Notice that gy0 = gy4 * bw43210, gy1 = gy4 * bw4321 etc, we now also get a formula for g_additional_inputs.

Subject: [PATCH 1383/1424] [export] Move example inputs in move_to_device_pass
 (#162301)

Summary:
If i have a EP that's exported on CPU and want to AOTI compile it for CUDA. I need to use `move_to_device_pass`.

But in `torch._inductor.aoti_compile_and_package()`, it directly uses the `example_inputs` attached to the EP, so we should move the example inputs as well if applicable.

Test Plan:
buck2 run mode/dev-nosan caffe2/test:test_export -- -r test_move_device_example_inputs

Subject: [PATCH 1384/1424] [dynamo] Use relaxed CLOSURE_MATCH guard then
 ID_MATCH (#162247)

I am unable to write a test that would fail here. The reason is that when we do _dynamo.disable(fn) in the compiled frame, the id of disabled function changes but currently we guard on the original function - `fn` whose id is not changing. This PR still guards on the `fn.__code__` just to be more precise.

Thanks to @thenumberouscode for pointing this out.

Subject: [PATCH 1385/1424] [nativert] AOTI lowering and packaging as NativeRT
 delegate (#162285)

Summary:
A demo for creating AOTI delegate for NativeRT in OSS.

- It supports full graph lowering only.
- It leverages `executorch_call_delegate` HOP but doesn't rely on `executorch`.
- The delegate graph is obtained by tracing a `LoweredBackendModule` whose forward function calls `executorch_call_delegate`.
- The main difference between `executorch_call_delegate` and `aoti_call_delegate` is that the delegate graph from `executorch_call_delegate` doesn't have weights lifted as inputs.
- original_ep and delegate_ep are treated as flat EP dictionary and there is no nested structure.
- The naming contract is enforced by `model_name` and `backend_id`

Test Plan:
CI

Subject: [PATCH 1389/1424] Revert "Add return-max-scores to flex-attention
 (#161667)"

This reverts commit 486b20b73cfcf32a773a4301b1b97f91c157ce76.

Reverted https://github.com/pytorch/pytorch/pull/161667 on behalf of https://github.com/huydhn due to Sorry for reverting your change but reverting https://github.com/pytorch/pytorch/pull/161730 does not seem to fix all trunk failures ([comment](https://github.com/pytorch/pytorch/pull/161667#issuecomment-3263512642))

Subject: [PATCH 1390/1424] Build vLLM nightly wheels (#162000)

This uses the same approach as building triton wheel where we publish a nightly wheel for vLLM whenever its pinned commit is updated.  The key change is to use `pytorch/manylinux2_28-builder` as the base image to build vLLM, so there are a couple of changes on the vLLM Dockerfile used by lumen_cli

1. `pytorch/manylinux2_28-builder` is RedHat instead of Debian-based, so no apt-get
2. Fix a bug in `.github/actions/build-external-packages/action.yml` where `CUDA_VERSION` is not set correctly, preventing CUDA 12.9 build
3. Fix a bug in `.github/actions/build-external-packages/action.yml` where `TORCH_WHEELS_PATH` is not set correctly and always defaulted to `dist`
4. In vLLM Dockerfile, use the correct index for the selected CUDA version, i.e. https://download.pytorch.org/whl/nightly/cu12[89] for CUDA 12.[89]
5. Install torch, vision, audio in one command. Unlike the CI image `pytorch-linux-jammy-cuda12.8-cudnn9-py3.12-gcc11-vllm`, `pytorch/manylinux2_28-builder` doesn't have any torch dependencies preinstalled
6. Bump xformers version to 0.0.32.post2 now that PyTorch 2.8.0 has been landed on vLLM

We need to prepare 3 wheels for vLLM, xformers, and flashinfer-python. And I rename them in the same convention as PyTorch nightlies `MAJOR.MINOR.PATCH.devYYYYMMDD` so that vLLM nightlies will work with torch nightlies on the same date.

### Usage

* Install latest nightlies
```
pip install --pre torch torchvision torchaudio vllm xformers flashinfer_python \
  --index-url https://download.pytorch.org/whl/nightly/cu129
```

* Install a specific version
```
pip install --pre torch==2.9.0.dev20250903 torchvision torchaudio \
  vllm==1.0.0.dev20250903 \
  xformers=0.0.33.dev20250903 \
  flashinfer_python=0.2.14.dev20250903 \
  --index-url https://download.pytorch.org/whl/nightly/cu129
```

-# gx <── gy0 <─ gy1 <─ gy2 <─ gy3 <─ gy4
-#
-# We can compute gx using chain rule:
-#
-#     gx = gy0 * bw(y0, x),
-#
-# where gy0 denotes the graident of loss with respect to y0, and bw(y0, x) denotes the graident of y0 with
-# respect to x. Note that bw can be computed from forward body_fn easily using torch.autograd.grad.
-# We could substitute the unknowns gy0, gy1, ..., with chain rule until gy4:
-#
-#     gx = gy1 * bw(y1, y0) * bw(y0, x)
-#        = gy2 * bw(y2, y1) * bw(y1, y0) * bw(y0, x)

-#        = gy4 * bw(y4, y3) * bw(y3, y2) * bw(y2, y1) * bw(y1, y0) * bw(y0, x)
-#
-# since gy4 is the graient of the final output, which is given as the backward input, we've got a formula
-# to compute gx. A abbr for the formula is: gy4 * bw43210x
-#
-# In a similar way, we can compute g_additional_inputs using chain rule:
-#
-# g_additional_inputs = gy0 * bw(y0, addi) + gy1 * bw(y1, addi) + gy2 * bw(y2, addi) + ... + gy4 * bw(y4, addi)
-#
-# Notice that gy0 = gy4 * bw43210, gy1 = gy4 * bw4321 etc, we now also get a formula for g_additional_inputs.
-#
-# Implementation:
-# The idea of implementation is to construct a while_loop to calculate both gx and g_additional_inputs.
-# Specifically, we can implement the backward of while_loop with as follows:

-#     reversed_idx = fw_inps.size(0) - 1 - idx
-#     next_grad_carry, next_grad_additional_inputs  = bw(fw_inps[reversed_idx], fw_additional_inputs, grad_carries)
-#     return idx + 1, next_grad_carry, next_grad_additional_inputs + grad_additional_inputs
-#
-# idx = 0

Subject: [PATCH 1393/1424] Improve typing of ONNX decorators with ParamSpec
 (#162332)

## Summary
This PR improves typing in ONNX-related modules by replacing TypeVar bound to Callable[..., Any] with ParamSpec to preserve parameter types and avoid type erasure in decorator functions.

## Changes
- `torch/onnx/_internal/exporter/_flags.py`: Replace TCallable TypeVar with ParamSpec
- `torch/onnx/ops/_impl.py`: Replace _T TypeVar with ParamSpec for _onnx_op decorator
- `torch/onnx/_internal/exporter/_torchlib/_torchlib_registry.py`: Replace _T TypeVar with ParamSpec

## Motivation
The previous implementation used TypeVar bound to Callable which erased parameter type information to Any. ParamSpec preserves the exact parameter types and return types, providing better type safety and IDE support.

## Testing
- Verified all changes compile and import correctly
- Created comprehensive test suite to validate ParamSpec functionality
- No linting errors introduced
- Maintains backward compatibility

Fixes #142306

+#
+# We can compute gx using chain rule:
+#
+#     gx = gy0 * bw(y0, x),
+#
+# where gy0 denotes the graident of loss with respect to y0, and bw(y0, x) denotes the graident of y0 with
+# respect to x. Note that bw can be computed from forward body_fn easily using torch.autograd.grad.
+# We could substitute the unknowns gy0, gy1, ..., with chain rule until gy4:
+#
+#     gx = gy1 * bw(y1, y0) * bw(y0, x)
+#        = gy2 * bw(y2, y1) * bw(y1, y0) * bw(y0, x)

+#
+# since gy4 is the graient of the final output, which is given as the backward input, we've got a formula
+# to compute gx. A abbr for the formula is: gy4 * bw43210x
+#
+# In a similar way, we can compute g_additional_inputs using chain rule:
+#
+# g_additional_inputs = gy0 * bw(y0, addi) + gy1 * bw(y1, addi) + gy2 * bw(y2, addi) + ... + gy4 * bw(y4, addi)
+#
+# Notice that gy0 = gy4 * bw43210, gy1 = gy4 * bw4321 etc, we now also get a formula for g_additional_inputs.

Subject: [PATCH 1401/1424] [easy] [precompile] Convert CompileArtifacts to
 callable (#162169)

The goal of this PR stack is to be able to implement `aot_compile_module`, which AOT precompiles a torch.nn.Module.
Step 1 is a simple refactor to make CompileArtifacts itself the callable, which makes it easier to use directly.

Subject: [PATCH 1402/1424] Add BundledAOTAutogradSerializableCallable
 (#162170)

This PR hooks up the python wrapper inductor backend to aot_compile. This is *not* the best way for us to grab the output of AOTAutograd; that involves a refactor to make AOTAutograd itself return a serializable callable. I'll do that refactor soon, but I want a basic interface to test with for now.

In the medium term, we'll want aot_compile to call AOTAutograd directly, instead of using the TorchInductorWrapper's callback through compile_fx.

+    Level 4:    gl_ys4           ─> g_ys4,
+
+    where gl_y1 is the gradient of the loss with respect to ys1 and the input of backward.
+
+    To calculate the gradients of the inputs, the chain rule suggests:
+
+    g_xs0 = g_ys1
+    g_xs1 = g_ys1 * bw(ys0, xs1) = g_ys1 * bwxs01
+    g_xs2 = g_ys2 * bw(ys1, xs2) = g_ys2 * bwxs12
+    g_xs3 = g_ys3 * bw(ys2, xs3) = g_ys3 * bwxs23
+    g_xs4 = g_ys4 * bw(ys3, xs4) = g_ys4 * bwxs34
+
+    Notice the bw(...) is just the single step bw (instantaneous gradients), whose formula can be computed from combine_fn.
+    For example bw(ys3, xs4) (also abbreviated with bwxs34) computes the gradients ∂/∂xs4 combine_fn(ys3, xs4).
+    Similarly, bw(ys4, ys3) (also abbreviated with bwys43) computes the gradients ∂/∂ys3 combine_fn(ys3, xs4).
+
+    Let's break down how to calculate g_ys by recursively substituting the unknowns:
+
+    g_ys1 = gl_ys1 + g_ys2 * bw(ys2, ys1)
+          = gl_ys1 + (gl_ys2  + g_ys3 * bw(ys3, ys2)) * bw(ys2, ys1)
+          = gl_ys1 + gl_ys2 * bw(ys2, ys1) + g_ys3 * bw(ys3, ys2) * bw(y2, y1)
+          = gl_ys1 + gl_ys2 * bw(ys2, ys1) + gl_ys3 * bw(ys3, ys2) * bw(y2, y1) \
+                   + g_ys4 * bw(ys4, ys3) * bw(ys3, ys2) * bw(ys2, ys1)
+          = gl_ys1 + gl_ys2 * bw(ys2, ys1) + gl_ys3 * bw(ys3, ys2) * bw(y2, y1) \
+                   + gl_ys4 * bw(ys4, ys3) * bw(ys3, ys2) * bw(ys2, ys1)
+
+    Let's do the same for all the g_ys:
+    g_ys2 = gl_ys2 + gl_ys3 * bw(ys3, ys2) + gl_y4 * bw(ys4, ys3) * bw(ys3, ys2)
+    g_ys3 = gl_ys3 + gl_ys4 * bw(ys4, ys3)
+    g_ys4 = gl_ys4
+
+    Notice that the above can be re-written as columnwise multiplication of y_mat and gl_ys:
+
+    g_ys1   1, bwys21, bwys321, bwys4321       gl_ys1
+    g_ys2 = 0,    1  , bwys321, bwys4321   .   gl_ys2
+    g_ys3   0,    0  ,     1  , bwys4321       gl_ys3
+    g_ys4   0,    0  ,     0  ,        1       gl_ys4,
+
+    where bwys21 is an abbreviation for bw(ys2, ys1),
+    bwys321 is an abbreviation for bw(ys3, ys2) * bw(ys2, ys1) so on and so forth.
+
+    We could effectively compute the upper triangular matrix y_mat with:
+    cumprod([1, bwys21, bwys32, bwys43]) then masking out the values as needed.
+    Thus, only [1, bwys21, bwys32, bwys43] are required to compute the y_mat.

+
+        NOTE: [associative_scan autograd implementation]
+
+        The forward of associative_scan can be computed with the following steps:
+
+        1.) Compute the forward output of the associative_scan
+            ys = associative_scan(combine_fn, xs, additional_inputs)
+
+        The backward of associative_scan can be computed with the following steps:
+
+        2.) Prepare the backward graph
+            We prepare the backward graph to be used in the backward function.
+            We utilize ``create_bw_fn`` to generate the joint function:
+            combine_fn_bw = create_bw_fn(combine_fn, operands)
+            where operands = [ys{t-1}, xst, additional_inputs]
+
+        3.) Materialize the ``combine_fn_bw``
+            This is required because torch.compile and torch.autograd.grad
+            cannot trace through the joint backward function dynamically.
+
+        4.) Compute the single step bw (instantaneous gradients) at every step t
+            bwys{t-1}, bwxst = combine_fn_bw(ys{t-1}, xst, 1.)
+            Here we pass 1 as the upstream gradient to obtain the local partial derivatives.
+
+            This gives:
+                bwys = [bw(ys1, ys0), bw(ys2, ys1), ..., bw(ysT, ys{T-1})]
+                bwxs = [bw(ys1, xs0), bw(ys2, xs1), ..., bw(ys{T-1}, xsT)]
+
+        5.) Compute the gradient transition matrix y_mat
+
+            As shown in the example above, each input xst affects all later outputs ysi for i ≥ t.
+            According to the chain rule, each such path contributes a product of local gradients g_ysk.
+
+            For example:
+                ∂ysT/∂xst = ∂ysT/∂ys{T-1} * ∂ys{T-1}/∂ys{T-2} * ... * ∂ys{t+1}/∂yst * ∂yst/∂xst
+                        = bw(ysT, ys{T-1}) * bw(ys{T-1}, ys{T-2}) * ... * bw(ys{t+1}, yst) * bw(ys{t-1}, xst)
+
+            This motivates the use of a cumulative product over bwys to compute all such paths efficiently.
+
+            We now construct the matrix of gradient transition paths:
+
+            5.1 Repeat g_y values to form the base matrix
+                y_mat = [[1, bwys21, bwys32, bwys43],
+                         [1, bwys21, bwys32, bwys43],
+                         [1, bwys21, bwys32, bwys43],
+                         [1, bwys21, bwys32, bwys43]]
+
+            5.2 Mask the lower triangle (inclusive) with 1s
+                y_mat = [[1, bwys21, bwys32, bwys43],
+                         [1, 1     , bwys32, bwys43],
+                         [1, 1     , 1     , bwys43],
+                         [1, 1     , 1     , 1    ]]
+
+            5.3 Apply cumulative product row-wise
+                y_mat = cumprod(y_mat, dim=1)
+                Resulting in:
+                y_mat = [[1, bwys21, bwys32 * bwys21, bwys43 * bwys32 * bwys21],
+                         [1, 1      , bwys32         , bwys43 * bwys32         ],
+                         [1, 1      , 1              , bwys43                  ],
+                         [1, 1      , 1              , 1                       ]]
+
+            5.4 Zero out the lower triangle (exclusive)
+                Final y_mat:
+                y_mat = [[1, bwys21, bwys32 * bwys21, bwys43 * bwys32 * bwys21],
+                         [0, 1      , bwys32         , bwys43 * bwys32         ],
+                         [0, 0      , 1              , bwys43                  ],
+                         [0, 0      , 0              , 1                       ]]
+
+        6.) Scale the y_mat with the upstream gradients gl_ys
+            scaled_y_mat = y_mat * gl_ys
+            Each entry now holds the full contribution of ∂L/∂ysj to ∂L/∂xsi via the path through ysj.
+
+        7.) Reduce the scaled_y_mat with a row-wise sum
+            summed_y_mat = scaled_y_mat.sum(dim=1)
+            This accumulates all downstream contributions for each xst.
+
+        8.) Scale with the instantaneous input gradients bwxs
+            g_xs = summed_y_mat * bwxs
+
+            This gives the final input gradients:
+                g_xs = [∂L/∂xs0, ∂L/∂xs1, ..., ∂L/∂xsT]
+
+        NOTE: [scan partial grad handling]
+            If any element of xs or of the outputs does not require gradients
+            (i.e., requires_grad=False), then the corresponding gradients will be returned
+            as tensors of zeros with the same shape as the element.

Subject: [PATCH 1407/1424] [inductor][triton] more JITCallable._hash_lock
 support (#162244)

Follow-up to #161768.

Context: ProcessPool pickles the outputs before sending them back to the main process. Triton kernels have some un-pickleable fields, so `prepare_for_pickle()` is used to strip out those fields. Previously, in the standard case (without triton_bundler.py), `prepare_for_pickle()` would strip out the un-pickleable fields and they would never be added back after unpickling, because the un-pickleable fields were not actually needed after compilation finished.

In #161768 updated `prepare_for_pickle` to also strip out the `fn._hash_lock` field, a newly added field in JITCallable instances which is a `threading.RLock()`, which is not pickleable.

It turns out that we do need to restore the `fn._hash_lock` field, even in the non-triton_bundler case - the MultiKernel case uses the hash lock.

To do this, we add `restore_after_unpickle()` which will restore fields (or if the old fields are not provided, initialize just the hash_lock)

Compile time benchmarks look good, maybe a very minor regression (see the comment below on the PR)

Subject: [PATCH 1408/1424] [inductor][triton] support static cuda launcher
 after triton # 7866 (#162309)

Fixes static cuda launcher after https://github.com/triton-lang/triton/pull/7866.

Static cuda launcher checks to make sure that no hook knobs are set (and if they are, it throws an error). But Triton has changed the semantics of hooks so that "empty hooks" are now represented by empty `HookChain`s instead of being represented by `None`. This PR changes the way we define "empty hooks" to account for HookChains.

Subject: [PATCH 1409/1424] [AsyncTP] Fixes AsyncMM (#162040)

The original implementation set beta to be 1, which cause the out (C) being added to the the output. Thus if the output is not initialized as zero beforehand, the output can be incorrect.

Removing the alpha and beta fixes the issue.

Thanks @ngimel to figure out the root cause.

Subject: [PATCH 1412/1424] [upstream triton] update triton pin to triton 3.5
 (#162278)

Update PyTorch to the latest Triton release candidate branch (release/3.5.x in triton-lang/triton)

Notably:
* this does *not* include the version number bump from 3.4 -> 3.5 (we'll do that in a follow-up PR)
* sam_fast is still failing, so we've disabled it temporarily https://github.com/pytorch/pytorch/issues/162282 and we are committed to fixing it, ideally before the branch cut but possibly as a cherry-pick into the release branch.

Subject: [PATCH 1413/1424] [inductor] Runtime estimations: use nccl estimator;
 mm only benchmark mode (#161405)

During comms reordering , sink wait iterative observed previous runtime estimations pretty off for collectives and mms.

Adding optional usage of:
- c10d.time_estimator for collectives, which is based on NCCL estimator

Benchmark mode only for matmuls, as they are highly dependent on mm backend

- The logic mostly copied from Ruisi's PRs for inductor simple_fsdp https://github.com/pytorch/pytorch/pull/157572

This estimations corrections are in default `BaseSchedulerNode.estimate_runtime()`

Subject: [PATCH 1416/1424] [AsyncTP] Use assertEqual instead of allClose for
 bf16 tests (#162041)

The async tp result and regular MM result are very close. If we adjust the allclose threshold, the test succeeds. This seems to indicate that the error is from numerical error of low precision.

Subject: [PATCH 1418/1424] Add C++ function for
 torch.distributed.tensor._op_schema.is_view_op (#161595)

This seems to have been an especially slow one because of the repeated pybind access (schema is a pybind, as is arguments, and then we hit each argument). It's still ~~1% of total benchmark runtime because of the repeated single pybind function call, but that's a lot better.

Subject: [PATCH 1423/1424] CD Windows CUDA 13.0 build - fix packaging of cuda
 dlls (#162383)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Trying to fix https://github.com/pytorch/pytorch/issues/162333

CUDA 13.0 file structure changed. Instead of keeping most of dlls in bin folder its now in ``bin\x64`` except for cudnn dll. See attached picture :
