From 2923244ded1f5987724a913cd0d1e3ff1d95253c Mon Sep 17 00:00:00 2001 From: hinriksnaer Date: Mon, 24 Nov 2025 16:17:56 +0000 Subject: [PATCH 001/338] [dynamo] Remove redundant _nonvar_fields assignments in UserDefinedObjectVariable subclasses (#167801) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Removed redundant `_nonvar_fields` assignments from 5 UserDefinedObjectVariable subclasses. These explicit re-assignments are unnecessary because Python's class attribute inheritance automatically provides access to parent class attributes. **Classes cleaned up:** - UserDefinedDictVariable - UserDefinedSetVariable - UserDefinedListVariable - UserDefinedTupleVariable - MutableMappingVariable All 5 classes inherit from `UserDefinedObjectVariable`, which defines `_nonvar_fields`. The pattern `_nonvar_fields = UserDefinedObjectVariable._nonvar_fields` is pure redundancy - the child classes will automatically inherit this attribute from the parent. ## Changes - **Lines removed:** 10 (5 redundant assignments + 5 blank lines) - **File modified:** `torch/_dynamo/variables/user_defined.py` ## Impact - **Code reduction:** -10 lines - **Maintainability:** ↑ (less redundancy) - **Risk:** Zero (identical behavior via inheritance) Pull Request resolved: https://github.com/pytorch/pytorch/pull/167801 Approved by: https://github.com/guilhermeleobas --- torch/_dynamo/variables/user_defined.py | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/torch/_dynamo/variables/user_defined.py b/torch/_dynamo/variables/user_defined.py index fb676295535df..e87af5b87a75a 100644 --- a/torch/_dynamo/variables/user_defined.py +++ b/torch/_dynamo/variables/user_defined.py @@ -2018,8 +2018,6 @@ class UserDefinedDictVariable(UserDefinedObjectVariable): UserDefinedObjectVariable.

Simplified the x86 TORCH_CUDA_ARCH_LIST logic to reuse the base list in`.ci/manywheel/build_cuda.sh`. 2. Added function filter_aarch64_archs() that filters the TORCH_CUDA_ARCH_LIST for aarch64 based on the x86 code. 3. Added function in `.ci/pytorch/build.sh` to report error if ACL is not present. 4. Deprecated previous aarch64 scripts (`.ci/aarch64_linux/` folder). Improvements: 1. Significant improvement in build time for CUDA ARM wheel build - Reduced build time from 5.5–6 hours to 1 hour 40–50 minutes taking this 13.0 build for example, 6h 11m 46s to 1h 50m 1s ≈ 70 % faster build time old: https://github.com/pytorch/pytorch/actions/runs/19304934204/job/55209695430 new: https://github.com/pytorch/pytorch/actions/runs/19301014750/job/55195226316 Reason: MAX_JOBS=5 is now removed after we move away from original aarch64 build workflow, previously it was OOM in building flash-attn, new MAX_JOBS is 12. https://github.com/pytorch/pytorch/pull/166044/files#diff-ccef31095e4f2d203710232531c38bff3251e41cf73ec84ee59f224bb64034aeL280 2.

This PR appends a human-readable `repr(type)` as a trailing comment: ___check_type_id(x, 94229757490048) # ### What This Change Does - Adds `repr(t)` to improve readability of guard output. - No behavior or semantics are changed — this is a debug-only improvement. ### Testing Verified that `repr(type)` produces readable, accurate names for built-in, user-defined, and torch.nn module types. Runtime behavior is unchanged; CI will validate everything end-to-end.

For now we only support one effect within a subgraph. * During the tracing part of AOTAutograd, we will then wrap the subgraph to take in and output a token. Before: ``` def forward(self, x): repeated_subgraph0 = self.repeated_subgraph0 invoke_subgraph = torch.ops.higher_order.invoke_subgraph(repeated_subgraph0, 'subgraph_0', x) return invoke_subgraph def repeated_subgraph(self, x): record_memory = torch.ops.mylib.record_memory.default("forward", "N") add = torch.ops.aten.add(x, x) return add ``` After: ``` def forward(self, token, x): repeated_subgraph0 = self.repeated_subgraph0 invoke_subgraph = torch.ops.higher_order.invoke_subgraph(repeated_subgraph0, 'subgraph_0', token, x) getitem = invoke_subgraph[0] # output token getitem_1 = invoke_subgraph[1] return (getitem, getitem_1) def repeated_subgraph(self, token, x): with_effects = torch.ops.higher_order.with_effects(token, torch.ops.mylib.record_memory.default, 'forward', 'N') getitem = with_effects[0] # output token add = torch.ops.aten.add(x, x) return (getitem, add) ``` * Then there is a bunch of logic within `_remove_effect_tokens` to handle removing the effects from the invoke_subgraph subgraph Differential Revision: [D87392741](https://our.internmc.facebook.com/intern/diff/D87392741) Pull Request resolved: https://github.com/pytorch/pytorch/pull/167231 Approved by: https://github.com/anijain2305 --- test/export/test_converter.py | 2 +- test/export/test_passes.py | 15 +- test/export/test_torchbind.py | 12 +- test/higher_order_ops/test_with_effects.py | 100 ++++++++ torch/_guards.py | 18 ++ torch/_higher_order_ops/invoke_subgraph.py | 50 ++++ torch/export/_remove_effect_tokens_pass.py | 265 ++++++++++++--------- torch/export/_unlift.py | 24 +- 8 files changed, 352 insertions(+), 134 deletions(-) diff --git a/test/export/test_converter.py b/test/export/test_converter.py index e739e5c346677..5b608503a1168 100644 --- a/test/export/test_converter.py +++ b/test/export/test_converter.py @@ -1405,7 +1405,7 @@ def func3(x): # noqa: F841 ) # qnnpack not supported on s390x @xfailIfS390X - def test_ts2ep_convert_quantized_model(self): + def test_ts2ep_convert_quantized_model1(self): class Standalone(torch.nn.Module): def __init__(self): super().__init__() diff --git a/test/export/test_passes.py b/test/export/test_passes.py index 9cf442c27a2bb..866eeaaee3986 100644 --- a/test/export/test_passes.py +++ b/test/export/test_passes.py @@ -640,16 +640,13 @@ def forward(self, x): self.assertExpectedInline( without_token_ep.graph_module.code.strip(), """\ -def forward(self, token, obj_attr, x): - with_effects = torch.ops.higher_order.with_effects(token, torch.ops._TorchScriptTesting.takes_foo_tuple_return.default, foo = obj_attr, x = x);

The context of `unlift_tokens` is currently tokens are threaded as inputs and outputs of the toplevel graph produced by AOTAutograd. However we don't want the inductor traced graph to have any notion of effects/tokens, just that the tokens should introduce some extra dependency behavior. So, we unlift the tokens from the toplevel graph. Instead of placeholder nodes the tokens will come from a `_make_token` call, and instead of outputting the tokens we will sink all tokens into `_sink_tokens`. Similarly, we want the invoke_subgraph subgraph to not have any notion of tokens, so we will also remove the tokens from the inputs of the invoke_subgraph subgraph. However, we still need a way mark the invoke_subgraph call as being effectful at the toplevel module to prevent invoke_subgraph calls from being reordered, so I wrap the invoke_subgraph with an effects.

Previously, using negative values in the `indices` tensor caused an out-of-bounds error. This update wraps indices correctly, matching Python-style indexing semantics. ### 🔧 Changes - Modified `_take_along_dim_helper` to apply modulo logic for dimension-safe negative indexing. - Added a unit test `test_take_along_dim_negative_indices` to `test/test_indexing.py` to assert correctness of negative indexing behavior. ### 🧪 Testing ```bash pytest test/test_indexing.py -k test_take_along_dim_negative_indices ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/152161 Approved by: https://github.com/albanD --- aten/src/ATen/native/TensorAdvancedIndexing.cpp | 3 +++ torch/_refs/__init__.py | 4 ++++ torch/testing/_internal/common_methods_invocations.py | 8 ++++++++ 3 files changed, 15 insertions(+) diff --git a/aten/src/ATen/native/TensorAdvancedIndexing.cpp b/aten/src/ATen/native/TensorAdvancedIndexing.cpp index 6c7efb3c161b0..537faf2a9194f 100644 --- a/aten/src/ATen/native/TensorAdvancedIndexing.cpp +++ b/aten/src/ATen/native/TensorAdvancedIndexing.cpp @@ -2669,6 +2669,9 @@ inline std::tuple _take_along_dim_helper( broadcast_shape = infer_size_symint(indices_sizes, self.sym_sizes()); auto self_broadcasted = at::broadcast_to_symint(self, broadcast_shape); + // Wrap negative indices to positive (Python-style) + indices_broadcasted = + indices_broadcasted.remainder(self_broadcasted.size(dim)); return std::make_tuple( std::move(self_broadcasted), std::move(indices_broadcasted), diff --git a/torch/_refs/__init__.py b/torch/_refs/__init__.py index e56163266caa1..4255142614103 100644 --- a/torch/_refs/__init__.py +++ b/torch/_refs/__init__.py @@ -4914,6 +4914,10 @@ def take_along_dim( broadcast_shape = utils.infer_size_shapes(indices_sizes, a.size()) self_broadcast = broadcast_to(a, broadcast_shape) + # wrap negative indices + dim_size = self_broadcast.size(dim) + indices_broadcast = indices_broadcast % dim_size + return torch.gather(self_broadcast, dim, indices_broadcast) diff --git a/torch/testing/_internal/common_methods_invocations.py b/torch/testing/_internal/common_methods_invocations.py index 0cf0f50c23ef5..5f3454ef54cca 100644 --- a/torch/testing/_internal/common_methods_invocations.py +++ b/torch/testing/_internal/common_methods_invocations.py @@ -3007,6 +3007,14 @@ def sample_inputs_take_along_dim(op_info, device, dtype, requires_grad, **kwargs yield SampleInput( make_arg((S, S)), gather_variable((S, S // 2), 0, S, True, device=device)) + # Negative indices sample — guarded against python_ref + if not kwargs.get('is_python_ref', False): + neg_idx = gather_variable((S, S), 1, S, True, device=device) - S + yield SampleInput( + make_arg((S, S)), + neg_idx, + 1) + def error_inputs_aminmax_amax_amin(op_info, device, is_ref=False, **kwargs): From 6936e335f9b8ad0a83b65aa8af32b6b350e6f7d6 Mon Sep 17 00:00:00 2001 From: mansiag05 Date: Tue, 25 Nov 2025 00:20:21 +0000 Subject: [PATCH 029/338] =?UTF-8?q?Adding=20check=20for=20step=20size=3D0?= =?UTF-8?q?=20in=20unfold=20backward=20to=20avoid=20divide=20by=200=20?= =?UTF-8?q?=E2=80=A6=20(#162720)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit …or FPE.

When `unmap_block` is called, the allocator decreases `allocation_count` as expected: (see lines 862–867) https://github.com/pytorch/pytorch/blob/265397e178dab071294f6a10e35226fe333b2983/c10/xpu/XPUCachingAllocator.cpp#L862-L867 However, when an expandable segment is created via `try_allocate_expandable_block`, we never increment `allocation_count`. As a result, `allocation_count` can drop below its correct value after unmapping. # Solution This patch fixes the issue by ensuring `allocation_count` is incremented when creating a new expandable segment. # Additional Context PyTorch currently does not support using a custom allocator together with the expandable-segment feature in the memory pool. Therefore, we add an assertion to fail fast when this unsupported condition is detected.

It's because to call onednn's primitive, we need to prepare a bunch of data structs as its args, which has big overhead. In the past, such things are cached in the context and attached to torch jit graph. However, Inductor does not support non-tensor data on graph. This PR adds a cache of those data structs by using a static `std::unordered_map`, whose key is weight data address as an `int64` and value is a struct that contains all data needed to run a primitive. This cache is safe in most cases where weight data address won't change during inference and weight data are not reused by different layers. However, since we cannot guarantee the assumption, we define an environment variable `"ONEDNN_CACHE_CONTEXT_UNSAFE"` to control this feature. Users should use it at their own risk. We found >5% E2E performance gain when running ViT with PT2E static quantization on an 6th gen of Intel Xeon CPU. **Test plan** ``` pytest -sv test/test_quantization.py -k "qlinear and pt2e" ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/168150 Approved by: https://github.com/mingfeima, https://github.com/jerryzh168 --- .../ATen/native/quantized/cpu/OnednnUtils.h | 36 ++++++++++ .../src/ATen/native/quantized/cpu/qlinear.cpp | 69 ++++++++++++++----- test/quantization/core/test_quantized_op.py | 53 +++++++++----- 3 files changed, 125 insertions(+), 33 deletions(-) diff --git a/aten/src/ATen/native/quantized/cpu/OnednnUtils.h b/aten/src/ATen/native/quantized/cpu/OnednnUtils.h index 963a47a21fa9f..e3fe5c33406b6 100644 --- a/aten/src/ATen/native/quantized/cpu/OnednnUtils.h +++ b/aten/src/ATen/native/quantized/cpu/OnednnUtils.h @@ -462,4 +462,40 @@ at::Tensor _qconv_prepack_onednn( #define FP8E4M3_MAX 448.0 +#define CACHE_ONEDNN_CONTEXT_FLAG "ONEDNN_CACHE_CONTEXT_UNSAFE" + +struct QlinearForwardParams { + dnnl::matmul primitive; + ideep::exec_args args; + ideep::tensor packed_weight; + ideep::tensor weight_scales; + std::optional src_scale; + std::optional src_zero_point; + std::optional dst_scale; + std::optional dst_zero_point; + std::optional bias; + ideep::tensor scratchpad; + + void init_args() { + args.insert({DNNL_ARG_WEIGHTS, packed_weight}); + args.insert({DNNL_ARG_SCRATCHPAD, scratchpad}); + if (bias.has_value()) { + args.insert({DNNL_ARG_BIAS, bias.value()}); + } + if (src_scale.has_value()) { + args.insert({DNNL_ARG_ATTR_SCALES | DNNL_ARG_SRC, src_scale.value()}); + } + if (dst_scale.has_value()) { + args.insert({DNNL_ARG_ATTR_SCALES | DNNL_ARG_DST, dst_scale.value()}); + } + args.insert({DNNL_ARG_ATTR_SCALES | DNNL_ARG_WEIGHTS, weight_scales}); + if (src_zero_point.has_value()) { + args.insert({DNNL_ARG_ATTR_ZERO_POINTS | DNNL_ARG_SRC, src_zero_point.value()}); + } + if (dst_zero_point.has_value()) { + args.insert({DNNL_ARG_ATTR_ZERO_POINTS | DNNL_ARG_DST, dst_zero_point.value()}); + } + } +}; + #endif // #if AT_MKLDNN_ENABLED() diff --git a/aten/src/ATen/native/quantized/cpu/qlinear.cpp b/aten/src/ATen/native/quantized/cpu/qlinear.cpp index 7a80b166f8cb7..ea1e6456d22d0 100644 --- a/aten/src/ATen/native/quantized/cpu/qlinear.cpp +++ b/aten/src/ATen/native/quantized/cpu/qlinear.cpp @@ -1147,24 +1147,13 @@ static at::Tensor linear_int8_with_onednn_weight( dim == 2 ? input.contiguous() : input.reshape({-1, input.size(dim -

For example: ```cpp #include #include #include #include int8_t device = 0; int main() { std::cout << std::strlen((std::stringstream() << "Head" << device << "Tail").str().c_str()) << std::endl; std::cout << std::strlen((std::stringstream() << "Head" << static_cast(device) << "Tail").str().c_str()) << std::endl; std::cout << std::strlen((std::stringstream() << "Head" << +device << "Tail").str().c_str()) << std::endl; return 0; } ``` output ```bash 4 9 9 ``` Maybe we can use `+` instead of `static_cast`, but it needs discussion.

Unset LD_LIBRARY_PATH in check_binary.sh so that system libaries are not found by the linker. This will ensure that only packaged .so files in the whl are used by the runtime linker. E.g. in https://github.com/pytorch/pytorch/pull/166044 we had a problem of missing libopenblas.so but the check_binary.sh passed. - Allow DESIRED_PYTHON format cp310_cp310t. The script in .ci/python/set_desired_python.sh manipulates the env variable DESIRED_PYTHON, so this change allows the check_binary.sh to be used with the alt format.

Instead of maintaining a centralized list of hashable types and custom equality logic in _HashableTracker, we now delegate hashability checks, hash computation, and equality comparison to individual VariableTracker subclasses. ## Motivation The previous implementation had several issues: 1. Centralized logic: All hashability checks and hash computations were centralized in dicts.py, making it difficult to add support for new hashable types 2. Maintainability: Adding a new hashable type required modifying multiple locations in _HashableTracker (underlying_value, _eq_impl, and the is_hashable function) 3. Scattered knowledge: Type-specific hashing logic was separated from the type's own implementation 4. Limited extensibility: No clear protocol for VariableTracker subclasses to declare themselves as hashable ## Changes New Protocol Methods Added three new methods to the VariableTracker base class: 1. is_python_hashable(): Returns whether the underlying Python object is hashable 2. get_python_hash(): Computes the hash value for the underlying Python object 3. is_python_equal(other): Checks Python-level equality between two VariableTrackers The base implementation raises unimplemented() with helpful error messages, and subclasses override these methods as appropriate. ## Simplified _HashableTracker The _HashableTracker class in ConstDictVariable is now much simpler: - Removed underlying_value property (centralized type handling) - Removed _eq_impl static method (centralized equality logic) - Simplified __hash__() to delegate to vt.get_python_hash() - Simplified __eq__() to delegate to vt.is_python_equal() ## Decentralized Implementations Implemented the new protocol methods across relevant VariableTracker subclasses: - ConstantVariable, TensorVariable, TupleVariable, ListVariable - FrozensetVariable, FrozenDataClassVariable - BuiltinVariable, UserFunctionVariable, SkipFunctionVariable - FunctoolsPartialVariable, WeakRefVariable - NumpyVariable, NNModuleVariable, MethodWrapperVariable - TorchInGraphFunctionVariable, TorchHigherOrderOperatorVariable - TypingVariable, UserDefinedObjectVariable, UserDefinedClassVariable - SymNodeVariable, EnumVariable ## Enhanced Test Coverage Added 14 new test cases covering various hashable types as dictionary keys: - range, tuples, enums, frozensets - Typing constructs (e.g., typing.Union) - NumPy dtypes, method wrappers - Torch builtin functions, frozen dataclasses - Custom objects with __hash__ - Negative test for unhashable types (lists) ## Improved Error Messages Updated error messages to be more informative when encountering unhashable types, showing both the Python type and the VariableTracker type.

Sometimes, we have to check for these capabilities in the document, and then hard-code. This PR proposes a new unified API for users to check their accelerator capabilities. # Changes This PR creates a new data structure `DeviceCapability` containing the capabilities that an accelerator commonly has: - Supporting DataType (set to be supported as default): - `fp16`, `int32`, `complex` ... etc - Other capabilities (need to be discussed) To access the structure, this PR defines a new Python API in the Accelerator module -- `get_device_capability`. It takes `device` as an input and returns a dictionary containing the capabilities (now we have `supported_dtypes` as the key). # Usage ```python >>> import torch >>> import torch_openreg >>> torch.accelerator.get_device_capability('openreg:0') {'supported_dtypes': [torch.uint8, torch.int8, torch.int16, torch.int32, torch.int64, torch.float16, torch.float32, torch.float64, torch.complex32, torch.complex64, torch.complex128, torch.bool, torch.qint8, torch.quint8, torch.qint32, torch.bfloat16, torch.quint4x2, torch.quint2x4, torch.bits1x8, torch.bits2x4, torch.bits4x2, torch.bits8, torch.bits16, torch.float8_e5m2, torch.float8_e4m3fn, torch.float8_e5m2fnuz, torch.float8_e4m3fnuz, torch.uint16, torch.uint32, torch.uint64, torch.uint1, torch.uint2, torch.uint3, torch.uint4, torch.uint5, torch.uint6, torch.uint7, torch.int1, torch.int2, torch.int3, torch.int4, torch.int5, torch.int6, torch.int7, torch.float8_e8m0fnu, torch.float4_e2m1fn_x2]} ``` # TODO - So far, precision is the only capability to track, based on my knowledge. But we can find more capabilities in common, and the API should be designed for good extension. - It will support other in-tree accelerators, such as **cuda** and **mps**. - Clarify whether the capabilities are software or hardware supported.

If the tensor's last usage is on the side stream, then syncrhonization is needed to ensure the memory is not reused on the allocating stream until after the side stream is finished. Accordingly, we estimate the runtime of both streams, record an event on the side stream at the last usage of the tensor, and then wait on that event in the allocating stream. In order to find the right location to wait, we estimate the runtime of all ops on both streams, and find the corresponding location in the allocating stream where we think the side stream has finished its work based on the runtime estimates. We then insert a `synced_deallocation` op at that location. This op waits on an event and takes a dummy tensor argument. This final usage of the tensor as a dummy argument serves the function of delaying the deallocation (and any subsequent reuse) of the memory on the allocating stream until after the wait event has completed.

This can be considered a general follow up for the ND case to https://github.com/pytorch/pytorch/pull/160480#discussion_r2342953799 which added transpose support for 2D tensors.

This PR adds a fallback so in the case where we can't safetly generate a key for caching (eg. certain HOPs), we still generate a random nonce key for precompile.

[PATCH 095/338] [AOTI] Fix a GPU memory leak caused by reference circle (#168063) Summary: Fix https://github.com/pytorch/pytorch/issues/167630. There was a reference circle between GraphLowering and CppWrapperCpu due to caching, which makes GraphLowering unnecessarily hold some contant tensors causing GPU memory leaks. This PR fixes that by changing the cache to use the object id of GraphLowering as a part of the key.

This change refactors DTensor implementation so that it can be shared with Local Tensor. The existing Local Tensor implementation was incorrectly computing shard linear index based on number of elements in the tensor instead of shard coordinates. AutoParallel PP slices world mesh into "pp" submeshes for MPMD execution and "dp_mod_ep, ep" submeshes for SPMD execution. Local Tensor uses default process group (corresponding to the world mesh) to compute collective groups and assumes input local tensors have ranks from the world mesh. Local Tensor mode can be created with subset of ranks. This feature is used in AutoParallel PP integration. Therefore this change modifies Local Tensor collectives to execute only if all ranks from the deduced rank groups are present on local tensor inputs.

Instead of maintaining a centralized list of hashable types and custom equality logic in _HashableTracker, we now delegate hashability checks, hash computation, and equality comparison to individual VariableTracker subclasses. ## Motivation The previous implementation had several issues: 1. Centralized logic: All hashability checks and hash computations were centralized in dicts.py, making it difficult to add support for new hashable types 2. Maintainability: Adding a new hashable type required modifying multiple locations in _HashableTracker (underlying_value, _eq_impl, and the is_hashable function) 3. Scattered knowledge: Type-specific hashing logic was separated from the type's own implementation 4. Limited extensibility: No clear protocol for VariableTracker subclasses to declare themselves as hashable ## Changes New Protocol Methods Added three new methods to the VariableTracker base class: 1. is_python_hashable(): Returns whether the underlying Python object is hashable 2. get_python_hash(): Computes the hash value for the underlying Python object 3. is_python_equal(other): Checks Python-level equality between two VariableTrackers The base implementation raises unimplemented() with helpful error messages, and subclasses override these methods as appropriate. ## Simplified _HashableTracker The _HashableTracker class in ConstDictVariable is now much simpler: - Removed underlying_value property (centralized type handling) - Removed _eq_impl static method (centralized equality logic) - Simplified __hash__() to delegate to vt.get_python_hash() - Simplified __eq__() to delegate to vt.is_python_equal() ## Decentralized Implementations Implemented the new protocol methods across relevant VariableTracker subclasses: - ConstantVariable, TensorVariable, TupleVariable, ListVariable - FrozensetVariable, FrozenDataClassVariable - BuiltinVariable, UserFunctionVariable, SkipFunctionVariable - FunctoolsPartialVariable, WeakRefVariable - NumpyVariable, NNModuleVariable, MethodWrapperVariable - TorchInGraphFunctionVariable, TorchHigherOrderOperatorVariable - TypingVariable, UserDefinedObjectVariable, UserDefinedClassVariable - SymNodeVariable, EnumVariable ## Enhanced Test Coverage Added 14 new test cases covering various hashable types as dictionary keys: - range, tuples, enums, frozensets - Typing constructs (e.g., typing.Union) - NumPy dtypes, method wrappers - Torch builtin functions, frozen dataclasses - Custom objects with __hash__ - Negative test for unhashable types (lists) ## Improved Error Messages Updated error messages to be more informative when encountering unhashable types, showing both the Python type and the VariableTracker type.

without crashing the job (#169064) Summary: Opts to capture timeout errors during compilation without forcing process failure. Useful to avoid hangs in MAST jobs. We may want to consider a configuration option for this to avoid wasted compute by never pruning bad config options.

This meant these strategies were always available, even when CP was not enabled, which could lead to incorrect sharding behavior as these sharding rules are not mathmetically correct without CP. 1. **Created new module**: `torch/distributed/tensor/experimental/_context_parallel/_sharding_rules.py` - Implements `op_strategy_context()` - a context manager for temporarily registering/unregistering strategies - Defines CP-enhanced strategy functions for all 6 scaled_dot_product_attention ops (forward and backward for flash, efficient, and cudnn variants) - Provides `register_cp_sharding_rules()` and `unregister_cp_sharding_rules()` APIs 2. **Updated `_matrix_ops.py`** - Removed all CP-specific sharding rules (sequence dimension sharding strategies) - Base strategies now only contain replicate, tensor parallelism, and batch sharding strategies 3. **Updated `_attention.py`** - `_enable_cp_dtensor_dispatcher()` now calls `register_cp_sharding_rules()` to dynamically add CP strategies - ~`_disable_cp_dtensor_dispatcher()` now calls `unregister_cp_sharding_rules()` to restore original strategies~ This will invalidate all the sharding prop caches. Disable it for now.

The results are validated in the improved testing that the ``___dict_contains`` will be sorted based on the verbose part. The first solution was also suggested in https://fb.workplace.com/groups/1075192433118967/permalink/1650742858897252/ by sorting the ``get_leaf_guards()`` in ``construct_manager_string``. 2. The second solution will be adopted the ``OrderedSet`` in setGuards during guards construction to make sure the ``contain_dict`` are displayed as the order of being added. We decided to pursuit the second options to reduce the sorting time overhead and simplicity.

Sometimes, we have to check for these capabilities in the document, and then hard-code. This PR proposes a new unified API for users to check their accelerator capabilities. # Changes This PR creates a new data structure `DeviceCapability` containing the capabilities that an accelerator commonly has: - Supporting DataType (set to be supported as default): - `fp16`, `int32`, `complex` ... etc - Other capabilities (need to be discussed) To access the structure, this PR defines a new Python API in the Accelerator module -- `get_device_capability`. It takes `device` as an input and returns a dictionary containing the capabilities (now we have `supported_dtypes` as the key). # Usage ```python >>> import torch >>> import torch_openreg >>> torch.accelerator.get_device_capability('openreg:0') {'supported_dtypes': [torch.uint8, torch.int8, torch.int16, torch.int32, torch.int64, torch.float16, torch.float32, torch.float64, torch.complex32, torch.complex64, torch.complex128, torch.bool, torch.qint8, torch.quint8, torch.qint32, torch.bfloat16, torch.quint4x2, torch.quint2x4, torch.bits1x8, torch.bits2x4, torch.bits4x2, torch.bits8, torch.bits16, torch.float8_e5m2, torch.float8_e4m3fn, torch.float8_e5m2fnuz, torch.float8_e4m3fnuz, torch.uint16, torch.uint32, torch.uint64, torch.uint1, torch.uint2, torch.uint3, torch.uint4, torch.uint5, torch.uint6, torch.uint7, torch.int1, torch.int2, torch.int3, torch.int4, torch.int5, torch.int6, torch.int7, torch.float8_e8m0fnu, torch.float4_e2m1fn_x2]} ``` # TODO - So far, precision is the only capability to track, based on my knowledge. But we can find more capabilities in common, and the API should be designed for good extension. - It will support other in-tree accelerators, such as **cuda** and **mps**. - Clarify whether the capabilities are software or hardware supported.

We do this by reusing `restore_side_effects` flag as much as possible. Based on my understanding, this flag works by: **When `restore_side_effects = True` (default)**: - Side effects data structure is saved before tracing and restored after - Intermediate tensors/symints are NOT captured as extra outputs - Used by most HOPs **When `restore_side_effects = False`**: - Side effects data structure is NOT restored - Intermediate tensors/symints ARE captured and returned as extra outputs - Used by `invoke_subgraph` (always) and `checkpoint` (when `config.skip_fwd_side_effects_in_bwd_under_checkpoint=True`) We had to keep some `under_activation_checkpointing` due to legacy FSDP changes.

issues (#169062) Summary: Add logging at the beginning of the autotuning process to capture the shapes being benchmarked before timeouts occur. This helps identify which specific tensor shapes cause compilation or benchmarking to hang, enabling faster debugging of timeout issues during kernel selection. Test Plan: Ran the code with a model that previously timed out during autotuning and verified that the shape information is now logged before the timeout occurs, making it easy to identify problematic shapes.

`/data/users/wouterdevriendt/fbsource/xplat/caffe2/torch/csrc/jit/runtime/static/passes.cpp`, but the file still uses the `ConstantPooling` function in the `SplitOutPrecomputeOpsForSparseNN` function.

Currently `make_fallback` doesn't work for aten.native_layer_norm due to decomposition. This PR prevents the decomposition, following the PR [#151637](https://github.com/pytorch/pytorch/pull/151637) where XPU enabled fallback for embedding_dense_backward. **This PR:** https://github.com/pytorch/pytorch/pull/168290 was reverted because it caused runtime failures for mtia tests ([T245927718](https://www.internalfb.com/intern/tasks/?t=245927718)). Not sure why the internal CI didn't prevent the diff landing though. After investigation, I think the failures were caused by `torch.mtia.is_available()`: 1. The API didn't run lazy initialization of mtia device, which caused error when this API was run by Inductor while mtia device hasn't been initialized. This issue should be fixed by D88058718. 2. I also found some failing tests were run without mtia device, which causes `torch.mtia.is_available()` returns false. ## This PR Exactly copy of https://github.com/pytorch/pytorch/pull/168290, except for changing `torch.mtia.is_available()` to `torch.mtia._is_compiled()`, which doesn't require mtia device to be initialized. And I verified the failed tests can pass with `torch.mtia._is_compiled()`. `torch.mtia._is_compiled()` checks whether MTIA hook is registered, so should not affect non-MTIA program.

It does the following: 1. Registered the `_scaled_mm` and `_scaled_mm_v2` op for XPU. 2. Enables XPU tests in `test_scaled_matmul_cuda.py`. 3. Update torch-xpu-ops pin to remove fallback `scaled_mm` to CPU implementation. ## PR Stack: - https://github.com/pytorch/pytorch/pull/165978 : implementation of XPU scaled_mm and oneDNN kernel - https://github.com/pytorch/pytorch/pull/167518 : implementation of XPU scaled_mm_v2 -

So, here we fully get rid of restore_side_effects, and leave it to the caller of the auto_flattening speculate subgraph to do this manually. We introduce allow_side_effects flag, which exposes intermediates to outputs and also sets up side effects to not raise when it sees a mutation during hop tracing.

When torch.linalg.eig() is called on a real-valued CUDA tensor that produces complex eigenvalues, the implementation previously transferred eigenvectors to CPU for decoding, then transferred them back to GPU. This PR keeps all operations on the GPU, improving performance by ~8-10%. ## PR Overview This PR makes linalg_eig_make_complex_eigenvectors dispatchable and adds a CUDA kernel implementation. The changes span 4 commits: **Commit 1: Add dispatch infrastructure** - Declares DECLARE_DISPATCH stub for linalg_eig_make_complex_eigenvectors - File: aten/src/ATen/native/BatchLinearAlgebra.h **Commit 2: Refactor for dispatch** - Moves CPU implementation to dispatch system - Removes GPU-to-CPU synchronization from call site - Preserves existing CPU implementation exactly (rename only) - Files: aten/src/ATen/native/BatchLinearAlgebra.cpp, BatchLinearAlgebraKernel.cpp **Commit 3: Add CUDA kernel** - Implements parallel CUDA kernel for eigenvector decoding - Parallelizes across batch, eigenvectors, and elements - Uses AT_DISPATCH_V2 for float32/float64 support - File: aten/src/ATen/native/cuda/BatchLinearAlgebraEig.cu **Commit 4: Add comprehensive test** - Tests CUDA kernel with rotation matrices (known analytical eigenvalues) - Validates fundamental identity: A@v = λv - Covers complex eigenvalues, real eigenvalues, and batched operations - File: test/test_linalg.py Now, for CUDA tensors, the entire pipeline runs on GPU with no host synchronization. ## Performance Results Benchmarked on NVIDIA H200 with CUDA 12.8 using block-diagonal rotation matrices (which guarantee complex eigenvalues, triggering the eigenvector decoding path). Timing method: Wall-clock with GPU synchronization, 20 iterations after 5 warmup runs.

In the forward method of TransformerEncoderLayer, the device whitelist for the Fast Path implementation by default only includes "cpu" and "cuda". This change explicitly adds the "xpu" device type to the supported list. This ensures that when XPU tensors are used as input, the code correctly selects and executes the highly optimized C++ fused kernel (torch._transformer_encoder_layer_fwd), instead of falling back to the slower, unoptimized Python implementation.

For example: ```python def inference_with_grad(): x = x_data.requires_grad_(True) # Forward: checkpoint node computed here z = torch.utils.checkpoint.checkpoint(lambda a: torch.sin(a), x) loss = z.sum() # Backward: checkpoint node only used here dx = torch.autograd.grad(loss, x)[0] return dx ``` Without optimization, the checkpointed `sin(x)` is computed during forward and held in memory until backward. This wastes memory if it's only needed in backward. Adds `rematerialize_ac_nodes()` pass that: 1. **Duplicates AC nodes used in both forward/backward**: Keeps in forward, recomputes in backward The pass is controlled by the config flag `torch._functorch.config.enable_inference_mode_ac_reordering` (default: `False`). The pass works in several steps: 1. **Find backward boundary**: Identify where backward computation starts using metadata annotations 2. **Categorize AC nodes**: Classify each AC node based on usage 3. **Rebuild graph**: - Backward: Duplicate AC chains for nodes used in both forward and backward while maintaining original order 4. **DCE** Use DCE to clean up forward nodes since some of them are only used in backward. **User code:** ```python def inference_with_grad(arg0_1, arg1_1): # Checkpointed computation z = torch.utils.checkpoint.checkpoint( lambda a, b: torch.sigmoid(torch.mm(a, b)), arg0_1, arg1_1, use_reentrant=False ) loss = z.sum() # Backward in same graph with torch.fx.traceback.annotate({"backward": 0}): grads = torch.autograd.grad(loss, (arg0_1, arg1_1)) return grads ``` **Compiled graph without AC reordering:** ```python # Forward mm = torch.mm(arg0_1, arg1_1) sigmoid = torch.sigmoid(mm) # AC node computed in forward detach = sigmoid.detach() # Saved for backward sum_1 = sigmoid.sum() # Backward sigmoid_backward = ... # Uses saved sigmoid (held in memory since forward) mm_1 = torch.mm(t, sigmoid_backward) mm_2 = torch.mm(sigmoid_backward, t_1) # Operation counts: mm=3, sigmoid=1 # Memory: sigmoid held from forward through backward ``` **Compiled graph with AC reordering:** ```python # Forward mm = torch.mm(arg0_1, arg1_1) sigmoid = torch.sigmoid(mm) # AC node computed for sum sum_1 = sigmoid.sum() # Used in forward, then freed # Backward - AC nodes recomputed just-in-time mm_recomputed = torch.mm(arg0_1, arg1_1) # Recompute sigmoid_recomputed = torch.sigmoid(mm_recomputed) # Recompute detach = sigmoid_recomputed.detach() # Use recomputed version sigmoid_backward = ... mm_1 = torch.mm(t, sigmoid_backward) mm_2 = torch.mm(sigmoid_backward, t_1) # Operation counts: mm=4, sigmoid=2 # Memory: sigmoid freed after forward, recomputed just-in-time ``` We tested on a synthetic large model which looks like: ```python def large_model(x, weights): """ Large model with multiple checkpointed transformer blocks. Simulates a model with ~6 checkpointed layers. """ # Initial projection x = torch.sin(x) # Checkpointed block 1 w1_1, w1_2, w1_3, w1_4 = weights[0:4] x = torch.utils.checkpoint.checkpoint( transformer_block, x, w1_1, w1_2, w1_3, w1_4, use_reentrant=False ) x = torch.nn.functional.layer_norm(x, x.shape[-1:]) # Checkpointed block 2 w2_1, w2_2, w2_3, w2_4 = weights[4:8] x = torch.utils.checkpoint.checkpoint( transformer_block, x, w2_1, w2_2, w2_3, w2_4, use_reentrant=False ) x = torch.nn.functional.layer_norm(x, x.shape[-1:]) # Checkpointed block 3 w3_1, w3_2, w3_3, w3_4 = weights[8:12] x = torch.utils.checkpoint.checkpoint( transformer_block, x, w3_1, w3_2, w3_3, w3_4, use_reentrant=False ) x = torch.nn.functional.layer_norm(x, x.shape[-1:]) # Checkpointed block 4 w4_1, w4_2, w4_3, w4_4 = weights[12:16] x = torch.utils.checkpoint.checkpoint( transformer_block, x, w4_1, w4_2, w4_3, w4_4, use_reentrant=False ) x = torch.nn.functional.layer_norm(x, x.shape[-1:]) # Checkpointed block 5 w5_1, w5_2, w5_3, w5_4 = weights[16:20] x = torch.utils.checkpoint.checkpoint( transformer_block, x, w5_1, w5_2, w5_3, w5_4, use_reentrant=False ) x = torch.nn.functional.layer_norm(x, x.shape[-1:]) # Checkpointed block 6 w6_1, w6_2, w6_3, w6_4 = weights[20:24] x = torch.utils.checkpoint.checkpoint( transformer_block, x, w6_1, w6_2, w6_3, w6_4, use_reentrant=False ) x = torch.nn.functional.layer_norm(x, x.shape[-1:]) return x ``` The naive inference graph has peak memory of 2700MB while with reordering pass, we achieve around 1100MB which is more or less same as eager peak memory. **Next Steps** Currently, we manually annotate the backward region using fx annotation API, but we should automatically tag them when torchdynamo encounter torch.autograd.grad.

I have done a thorough investigation and some of these tests are passing simply by pure random chance. test_matmul_mv_cpu_bfloat16 passes in it's current form but can be made to fail simply by changing the random seed. test_matmul_mv_cpu_float32 fails but equally can be made to pass by setting the random seed. The failure message is this something like this ``` Mismatched elements: 50000 / 50000 (100.0%) Greatest absolute difference: 0.0859375 at index (0,) (up to 1e-05 allowed) Greatest relative difference: 3.4299155231565237e-06 at index (0,) (up to 1.3e-06 allowed) To execute this test, run the following from the base repo dir: python test/test_linalg.py TestLinalgCPU.test_matmul_mv_cpu_float32 ``` The test is the following ``` n = 50_000 A = torch.ones(n, n, dtype=dtype, device=device) B = torch.rand(n, dtype=dtype, device=device) C = torch.matmul(A, B) self.assertEqual(C, B.sum().expand(B.shape)) ``` The problem is that we are testing 2 different reduction paths for a very large N( torch.matmul and torch.sum will perform a different order of summation, especially with vectorization ). So it is entirely expected that C and B.sum() will have large differences. This is made worse by the use of the uniform distribution instead of the normal distribution. Below are 2 charts which demonstrate that errors tends to accumulate into larger magnitudes for the uniform distribution. ( Note the x axis is square root of N ) ### mean error calculated over different 100 seeds for torch.rand linalg_matmul ### mean error calculated over different 100 seeds for torch.randn randn There is some mathematical proof for this.... following a random walk model to calculate the expected error .. with normally distributed data the error scales with square root of N ( N^1/2 ) , where as for uniformly distributed data the error scales with N^3/2 . The reason being is that for normally distributed data the running sum tends to oscillate around 0, so the magnitude of the error stays roughly constant, where as for non-zero mean random data the sum grows and so does the magnitude of the error. ### The Fix ### - I have changed rand to randn. - Technically the comment says this is regression test for a segmentation fault https://github.com/pytorch/pytorch/issues/150637 so in theory we don't need to check for closeness, we could just put sanity checks in opn the size and shape. - For completeness we keep the assertEqual but i have overridden the tolerances with suitably large atol and rtol which have been made from the mathematical theory but also from evidence of running this with 100 seeds.

17 00:00:00 2001 From: Frank Lin Date: Wed, 3 Dec 2025 18:37:58 +0000 Subject: [PATCH 192/338] The Nested Pool (#168382) This PR fixes issue #161193 by simply reversing the iteration order over captures_underway. After discussing with @galv, we decided to land this minimal fix first to unblock nested MemPool usage. Long-term, the underlying infrastructure (e.g., captures_underway) still needs refactoring to clearly define the interaction between graph capture, MemPools, and threads. That broader cleanup will be addressed in #168137.

It might be easier to work with a graph that already has scooped out regions for better abstraction. If not done this way, it is necessary to run the regional inductor pass at the very end of the compiler to avoid striding issues.

Existing autotuning only supports single-process benchmarking, making it impossible to autotune collective ops that require multi-rank coordination. **Summary:** Added distributed benchmarking via `benchmark_collective_choice()` and `register_custom_op_autotuning()` API. All ranks are synchronized and benchmarked at the same time to ensure a fair comparison. The benchmark across all possible ranks(world_size) has a timeout detection(default 30s, configurable in configs.py) and exception handling to prevent deadlocks. If any rank times out or encounters an exception, all ranks fallback to regular benchmark together. **Example:** ```python # Define custom op with multiple implementations @torch.library.custom_op("mylib::allreduce", mutates_args=()) def my_allreduce(x: torch.Tensor) -> torch.Tensor: return torch.ops._c10d_functional.all_reduce_(x.clone(), "sum", "default") # Register autotuning choices register_custom_op_autotuning( my_allreduce, configs=[ CustomOpConfig(lambda x: all_reduce_(x.clone(), "sum", "default")), CustomOpConfig(lambda x: all_reduce_(x.clone(), "avg", "default") * world_size), ], ) # Compile and autotune model = torch.compile(MyModel()) output = model(input) # Autotuning happens here ``` **Implementation:** Different from regular benchmark which calls benchmarker.benchmark with warmup and rep, collective op benchmarking should handle barrier synchronization and timing. So I created `collective_benchmark` for subgraphcaller choice to only run the implementation once with cached compiled modules. Then the timing and synchronization will be handled in select_algorithm.py **example log** ``` Autotune Choices Stats: {"num_choices": 3, "num_triton_choices": 0, "best_kernel":

Previously the behavior of with_effects is that we turn each with_effects(op, ..) call into an `ir.EffectfulKernel`, and the `op` is treated as a FallbackKernel. However in the case of `invoke_subgraph`, we want it to be an `ir.InvokeSubgraph` to trigger the invoke_subgraph inductor lowering logic. So now instead of turning with_effects into an `ir.EffectfulKernel`, I just add this dependency information to `V.graph.additional_star_deps`, similar to `V.graph.additional_buffer_deps` which is used by `control_deps`.

Sometimes, we have to check for these capabilities in the document, and then hard-code. This PR proposes a new unified API for users to check their accelerator capabilities. # Changes This PR creates a new data structure `DeviceCapability` containing the capabilities that an accelerator commonly has: - Supporting DataType (set to be supported as default): - `fp16`, `int32`, `complex` ... etc - Other capabilities (need to be discussed) To access the structure, this PR defines a new Python API in the Accelerator module -- `get_device_capability`. It takes `device` as an input and returns a dictionary containing the capabilities (now we have `supported_dtypes` as the key). # Usage ```python >>> import torch >>> import torch_openreg >>> torch.accelerator.get_device_capability('openreg:0') {'supported_dtypes': [torch.uint8, torch.int8, torch.int16, torch.int32, torch.int64, torch.float16, torch.float32, torch.float64, torch.complex32, torch.complex64, torch.complex128, torch.bool, torch.qint8, torch.quint8, torch.qint32, torch.bfloat16, torch.quint4x2, torch.quint2x4, torch.bits1x8, torch.bits2x4, torch.bits4x2, torch.bits8, torch.bits16, torch.float8_e5m2, torch.float8_e4m3fn, torch.float8_e5m2fnuz, torch.float8_e4m3fnuz, torch.uint16, torch.uint32, torch.uint64, torch.uint1, torch.uint2, torch.uint3, torch.uint4, torch.uint5, torch.uint6, torch.uint7, torch.int1, torch.int2, torch.int3, torch.int4, torch.int5, torch.int6, torch.int7, torch.float8_e8m0fnu, torch.float4_e2m1fn_x2]} ``` # TODO - So far, precision is the only capability to track, based on my knowledge. But we can find more capabilities in common, and the API should be designed for good extension. - It will support other in-tree accelerators, such as **cuda** and **mps**. - Clarify whether the capabilities are software or hardware supported.

This is because RNN module's `flatten_parameters()` method calls `p.data_ptr()` for aliasing detection, causing "Cannot access data pointer of Tensor" errors on GPU. This PR fixes this issue by disabling cudnn during export time.

Existing autotuning only supports single-process benchmarking, making it impossible to autotune collective ops that require multi-rank coordination. **Summary:** Added distributed benchmarking via `benchmark_collective_choice()` and `register_custom_op_autotuning()` API. All ranks are synchronized and benchmarked at the same time to ensure a fair comparison. The benchmark across all possible ranks(world_size) has a timeout detection(default 30s, configurable in configs.py) and exception handling to prevent deadlocks. If any rank times out or encounters an exception, all ranks fallback to regular benchmark together. **Example:** ```python # Define custom op with multiple implementations @torch.library.custom_op("mylib::allreduce", mutates_args=()) def my_allreduce(x: torch.Tensor) -> torch.Tensor: return torch.ops._c10d_functional.all_reduce_(x.clone(), "sum", "default") # Register autotuning choices register_custom_op_autotuning( my_allreduce, configs=[ CustomOpConfig(lambda x: all_reduce_(x.clone(), "sum", "default")), CustomOpConfig(lambda x: all_reduce_(x.clone(), "avg", "default") * world_size), ], ) # Compile and autotune model = torch.compile(MyModel()) output = model(input) # Autotuning happens here ``` **Implementation:** Different from regular benchmark which calls benchmarker.benchmark with warmup and rep, collective op benchmarking should handle barrier synchronization and timing. So I created `collective_benchmark` for subgraphcaller choice to only run the implementation once with cached compiled modules. Then the timing and synchronization will be handled in select_algorithm.py **example log** ``` Autotune Choices Stats: {"num_choices": 3, "num_triton_choices": 0, "best_kernel":

Subject: [PATCH 242/338] [dynamo, guards] apply functools.cached_property to Source.name (#168131) Partial fix for https://github.com/pytorch/pytorch/issues/168118. Decreases guard build time from 25s -> 16s on a local tlparse. On the guard build benchmark, time went from 135.81s -> 84.66s However, there are a lot of changes to `source.name()` callsites. This could technically be avoided by writing our own `cached_property` decorator that requires the function call.

Typically, new accelerators only require a CPU backend as fallback purpose in case certain operations or functions are not yet ready. Furthermore, some PrivateUse1-related features are limited to allowing only one accelerator. Therefore, to align with real-world use cases, we are refactoring the current OpenReg integration to ensure that OpenReg-related tests are executed using **only the CPU** (currently, OpenReg test cases are executed in environments including GPUs). ## Design - **Isolation**: Removing OpenReg tests from the default global test case set prevents these tests from running in environments containing accelerators other than CPUs and provides a dedicated entry point for supporting the execution of OpenReg tests. - **Reuse**: The integration mechanism based on PrivateUse1 needs to support multiple platforms, such as Linux, Windows and OSX. Therefore, we need to enable openreg test cases for these platforms by adding openreg configuration items to the workflow specifically for each platform. ## Validation Run ```shell python test/run_test.py --dry-run &> ./selected_tests && grep "test_openreg" ./selected_tests python test/run_test.py --openreg --dry-run &> ./selected_tests && grep "test_openreg" ./selected_tests ``` to check if `test_openreg` is included by the default test case range. image ## New CI Jobs The new OpenReg CI jobs require minimal compute resources (not include GPU resource) and typically finish in less than 10 minutes. | Name | OS | Accelerator | Python | Compiler | Arch | Status | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | ----------- | ------ | -------- | ----- | --------- | | [linux-aarch64 / linux-jammy-aarch64-py3.10 / test (openreg, 1, 1, lf.linux.arm64.m7g.4xlarge) (push)](https://github.com/pytorch/pytorch/actions/runs/19557552621/job/56003633536?pr=167958)

But this broke BC in that after that PR `from(...)` is no longer usable without template arguments, which makes the code in fa3 https://github.com/Dao-AILab/flash-attention/blob/ad70a007e6287d4f7e766f94bcf2f9a813f20f6b/hopper/flash_api_stable.cpp#L1797-L1800 no longer compilable in 2.10 We could update the code in FA3, but that might require ifdefs for 2.9 vs 2.10 -- as a general principle for stable extensions, I'm not sure whether updating the extension code or not breaking BC of the headers is what we should go with here. But I'm leaning towards the latter. This PR takes the alternative approach of restoring torchaudio Windows CI sanity by replacing all `{from/to}` in torch/csrc/stable/stableivalue_conversions.h with `torch::stable::detail::{from/to}` rather than making the `from`/`to` in the global namespace a function pointer Confirmed that audio CI passes https://github.com/pytorch/audio/pull/4133 Pull Request resolved: https://github.com/pytorch/pytorch/pull/169475 Approved by: https://github.com/albanD --- .../libtorch_agnostic_2_9/csrc/kernel.cpp | 13 +- torch/csrc/stable/stableivalue_conversions.h | 155 +++++++++++------- 2 files changed, 104 insertions(+), 64 deletions(-) diff --git a/test/cpp_extensions/libtorch_agnostic_2_9_extension/libtorch_agnostic_2_9/csrc/kernel.cpp b/test/cpp_extensions/libtorch_agnostic_2_9_extension/libtorch_agnostic_2_9/csrc/kernel.cpp index 0304dfd8f0f4c..cf50a4d70e6d7 100644 --- a/test/cpp_extensions/libtorch_agnostic_2_9_extension/libtorch_agnostic_2_9/csrc/kernel.cpp +++ b/test/cpp_extensions/libtorch_agnostic_2_9_extension/libtorch_agnostic_2_9/csrc/kernel.cpp @@ -67,12 +67,23 @@ Tensor sgd_out_of_place( return out;

The reasons as to why this mapping over the one in https://github.com/pytorch/pytorch/pull/158137 are: - Prior work done to extend cuBLASLt coverage in `addmm` beyond just 1D bias and `beta=1, alpha=1`. As long as there is an activation after `addmm`, we can call Lt. This makes the check for pattern replacement leaner and agnostic to the inputs' meta-data (`addmm`'s checks for free). - Inductor intercepts `addmm` and replaces it with `alpha * [alpha != 1] * m1 @ m2 + beta * [beta != 1] * input` when followed by point-wise consumers (including activation functions). So it is way easier and cleaner to intercept just `addmm` (and not combinatorial set of patterns) before such replacements.

It also adds robustness checks such as device ID validation and supplements relevant test cases for stream context management. **Changes and Reasons** 1. OpenReg runtime (OpenRegStream.cpp) 1）Redesigned the ID of OpenReg Stream. In the new implementation: - StreamIdType=6 indicates the default stream, and StreamIdType=7 represents the external stream. Values 0-5 are reserved as priority codes for normal stream pools. OpenReg currently supports stream pools with priorities 0-1. This design makes the priority of stream pools more intuitive and easier to understand. - Modified StreamIdType from an enum to a regular class to support multi-priority scenarios. - Updated the implementation of OpenRegStream::stream() for retrieving orStream_t. - Adjusted the code in the original implementation that restricted stream pools to single-priority, enabling multi-priority support. 2）Enhanced robustness: added device validation, DeviceGuard initialization. 2. Tests (test_streams.py) Added assertions for "original stream restoration" in context exception paths and stream switching checks, covering key code paths.

This change exposes `set_signal_pad_size` and `get_signal_pad_size` APIs to allow users to configure the signal pad size before making symmetric memory allocations. ### Changes: #### 1. Core API (C++) - Renamed `signal_pad_size` constexpr to `default_signal_pad_size` in CUDASymmetricMemoryTypes.hpp - Added `get_signal_pad_size()` and `set_signal_pad_size(size_t)` function declarations in CUDASymmetricMemoryTypes.hpp - Implemented the functions in SymmetricMemory.cpp using `std::optional` to distinguish between default and user-configured values - Added TORCH_API exports in SymmetricMemory.hpp for public API access #### 2. Backend Updates - Updated CUDASymmetricMemory.cu to call `get_signal_pad_size()` instead of using the hardcoded constant - Updated NCCLSymmetricMemory.cu to use configurable signal pad size with local variable `signal_pad_size` - Updated NVSHMEMSymmetricMemory.cu to use configurable signal pad size with local variable `signal_pad_size` #### 3. Python Bindings - Added Python bindings in init.cpp with comprehensive docstrings explaining usage - Added Python wrapper functions in torch/distributed/_symmetric_memory/__init__.py - Updated `__all__` to export the new API functions #### 4. Tests - Added `test_get_signal_pad_size()` to verify the API returns a positive integer and Python/C++ consistency - Added `test_set_signal_pad_size()` to verify setting, getting, and restoring signal pad size values Test Plan: `PYTHONPATH=. python3 test/distributed/test_symmetric_memory.py` Pull Request resolved: https://github.com/pytorch/pytorch/pull/169156 Approved by: https://github.com/ngimel --- test/distributed/test_nvshmem_triton.py | 10 +++ test/distributed/test_symmetric_memory.py | 69 +++++++++++++++++ torch/_C/_distributed_c10d.pyi | 3 +- torch/csrc/distributed/c10d/init.cpp | 10 ++- .../c10d/symm_mem/CUDASymmetricMemory.cu | 9 +-- .../c10d/symm_mem/CUDASymmetricMemory.hpp | 1 -

The later records can not be ran without building FA3 from source, so we will ommit them until the dynamo FA3 PR is merged. The tweaks are to library-ify the script by commenting out everything other than the model class definitions, to change the pg initialization to use fake pg, and constant-ify some hyperparameters. The tests run locally, but this model specifically requires H100. I wasn't sure how to filter for that, so I skipped all the tests. This will be tested on the dynamo benchmark side: https://github.com/pytorch/pytorch/pull/169449.

Interpreter to preserve annotation (#169528) Similar to https://github.com/pytorch/pytorch/pull/165336 We have an issue when using fx_traceback.annotate and tracing HOPs. HOPs have bodies that have already been traced by Dynamo, and have the annotations. But when we lower that Dynamo HOP body to aten, we need to propagate the annotations to the aten nodes. To do this, we need to run the graph in Interpreter mode so the node meta can be propagated.

For example, this feature enables TorchTitan to load GPT-OSS models with de-quantization happening under the hood. 1. Test 1. We use `dcp.load(hf_state_dict, storage_reader=QuantizedHuggingFaceStorageReader(path=input_dir))` to load from GPT-OSS HF checkpoint, and map the `hf_state_dict` back to TorchTitan state dict. We build one test input, and compare two outputs: 1. Using `transformer` library to load GPT-OSS HF checkpoint and run inference on the test input; 2. We use the converted TorchTitan model to run inference on the test input. We compare the outputs by comparing the KL divergence of two output probability distributions. The result shows two models are very similar. Pasted Graphic 2. Test 2. With TorchTitan, we load the model directly from quantized GPT-OSS HF checkpoint, and do a test training.

This new convention replaces the previous mechanism of separate function pointers, and aligns with the latest DLPack standard as shown in PR [174](https://github.com/dmlc/dlpack/pull/174). Specifically, the new `DLPackExchangeAPI` struct is exposed as `torch.Tensor.__c_dlpack_exchange_api__`, which stores and exposes the following function pointers: * `managed_tensor_allocator` * `managed_tensor_from_py_object_no_sync` * `managed_tensor_to_py_object_no_sync` * `dltensor_from_py_object_no_sync` * `current_work_stream` Within the new `DLPackExchangeAPI` struct, the new `current_work_stream` function pointer allows more robust and integrated querying of the current device stream (e.g., CUDA stream) during DLPack tensor exchanges. All the conversion from/to DLPack has been updated to `_no_sync`, meaning you should use `current_work_stream` to explicitly handle stream synchronization. It also includes a non-owning DLTensor conversion `dltensor_from_py_object_no_sync` to avoid unnecessary reference counting. Following this change, the `dlpack.h` has been updated to the latest DLPack. Unit tests are added using `torch.utils.cpp_extension.load_inline` to avoid GIL release issues when calling `THPVariable_Wrap`.

The consumer is also expected to run the kernel with the same + * stream context as the producer. For example, when x, y, z is torch.Tensor, + * consumer should query exchange_api->current_work_stream to get the + * current stream and launch the kernel with the same stream. + * This setup is necessary for no synchronization in kernel launch and maximum compatibility + * with CUDA graph capture in the producer. + * This is the desirable behavior for library extension support for frameworks like PyTorch. + * - N1: data ingestion and retention + * + * Note that obj.__dlpack__() API should provide useful ways for N1. + * The primary focus of the current DLPackExchangeAPI is to enable faster exchange N0 + * with the support of the function pointer current_work_stream. + * + * Array/Tensor libraries should statically create and initialize this structure + * then return a pointer to DLPackExchangeAPI as an int value in Tensor/Array. + * The DLPackExchangeAPI* must stay alive throughout the lifetime of the process. + * + * One simple way to do so is to create a static instance of DLPackExchangeAPI + * within the framework and return a pointer to it. The following code + * shows an example to do so in C++.

To prevent a node from being DCEd in FX's DCE, we can register `torch.fx.node.has_side_effect(op)`. However this does not propagate to inductor. 1. Fixes FX DCE such that if an operator is wrapped with auto_functionalize, then we check if the operator passed to auto_functionalized has side effects to determine if that call should be DCEd 2. Fixes inductor's FallbackKernel's has_side_effect function to also check if the operator is in FX's _side_effectful_fns. This way operators registered as having side effects through `torch.fx.node.has_side_effect` will show up 5. Update FX DCE to log what nodes have been DCEd. Inductor's nodes that are DCEd will show up in `TORCH_LOGS="+inductor"` logs with the prefix, `removed dead buffer: ...` 6. If an operator has side effects, marked through torch.library._register_effectful_op, this will also make sure FX's DCE does not DCE the operator. a. Some additional changes needed to be made -- We mark all operators with ScriptObjects as inputs as being side effectful by default. However the above change causes an issue where if a graph contains a quantization op using a PackedParamsBase, then the op will not get DCEd, causing some unittest failures. So I marked some of the quantization ScriptObject classes as being not effectful.

Thus, unless backed_size_oblivious is on, the greatest lowerbound is [2+, ...]. So, this trips up a lot of models who can have a dynamic size with 0 or 1. I want a way for AOTI lowering users to easily check their dynamic shape spec is correct via `AOTI_RUNTIME_CHECK_INPUTS=1` which is a runtime env var. In-order to do that, I need to avoid any errors triggered by a wrong lowerbound. ## What does it look like? ``` // this is a lowerbound check if (arg0_1_size[0] < 2) { std::stringstream ss; ss << "input_handles[0]: dim value is too small at 0, " << "expected it to be >= 2, " << "but got: " << arg0_1_size[0] << "\n"; throw std::runtime_error(ss.str()); } ``` Differential Revision: D88203028 Pull Request resolved: https://github.com/pytorch/pytorch/pull/169430 Approved by: https://github.com/yushangdi, https://github.com/desertfire --- test/inductor/test_aot_inductor.py | 46 ++++++++++++++++++++++ torch/_inductor/codegen/cpp_wrapper_cpu.py | 4 +- torch/_inductor/config.py | 6 +++ 3 files changed, 55 insertions(+), 1 deletion(-) diff --git a/test/inductor/test_aot_inductor.py b/test/inductor/test_aot_inductor.py index 8e4102a57d682..2f1feedf6dd47 100644 --- a/test/inductor/test_aot_inductor.py +++ b/test/inductor/test_aot_inductor.py @@ -7999,6 +7999,52 @@ class AOTInductorTestABICompatibleMps(TestCase): ) +class TestCheckLowerboundConfig(TestCase): + def test_aoti_check_lowerbound_codegen(self): + """ + Test that check_lowerbound config controls lowerbound check codegen. + When check_lowerbound=False, no lowerbound checks should be generated. + """ + + class Model(torch.nn.Module): + def forward(self, x): + return x + 1 + + model = Model() + batch = Dim("batch", min=2, max=10) + example_inputs = (torch.randn(4, 3),) + + # Test with check_lowerbound=True (default) + with config.patch({"aot_inductor.check_lowerbound": True}): + result, code = run_and_get_cpp_code( + AOTIRunnerUtil.legacy_compile, + model, + example_inputs, + dynamic_shapes={"x": {0: batch}}, + ) + # Should have lowerbound checks + FileCheck().check_count( + "dim value is too small", + 1, + exactly=True, + ).run(code) + + # Test with check_lowerbound=False + with config.patch({"aot_inductor.check_lowerbound": False}): + result, code = run_and_get_cpp_code( + AOTIRunnerUtil.legacy_compile, + model, + example_inputs, + dynamic_shapes={"x": {0: batch}}, + ) + # Should NOT have lowerbound checks + FileCheck().check_count( + "dim value is too small", + 0, + exactly=True, + ).run(code) + + if __name__ == "__main__": from torch._inductor.test_case import run_tests diff --git a/torch/_inductor/codegen/cpp_wrapper_cpu.py b/torch/_inductor/codegen/cpp_wrapper_cpu.py index 9ec44c6c2790f..16522d9832ec0 100644 --- a/torch/_inductor/codegen/cpp_wrapper_cpu.py +++ b/torch/_inductor/codegen/cpp_wrapper_cpu.py @@ -423,7 +423,9 @@ def gen_check(handle_kind, idx, name, tensor): from torch.utils._sympy.value_ranges import bound_sympy sym_range = bound_sympy(d, V.graph.sizevars.shape_env.var_to_range) -

The previous code generated N output strategies for the stack op, one based on each of the original N input strategies. However, Each of the N output strategies was the same. The heuristic in the stack rule is to find one of the N inputs and follow that one. We now just generate one output strategy.

Changes with the PR: - `mark_unbacked()` would previously error on tensor subclasses; now for DTensors it allocates unbacked symbols for both inner & outer sizes. The main motivation here is for testing, so happy to tweak semantics. The unbacked binding search process also now matches on DTensor outer sizes. - Selecting an op strategy in sharding propagation is based on minimal redistribution costs, and these costs are functions of tensor shapes, so can be unbacked expressions. This PR makes this process more unbacked-friendly, choosing negative or zero-cost strategies when they're available. When these "trivial" strategies aren't available, selection requires comparing unbacked costs, addressed in the next PR (with usage of fallback hints). - For matmul strategies, sharding prop rules filter out strategies where the matmul inputs fail the `is_tensor_shardable` check on the given DeviceMesh. In eager, this filters out cases where `size of sharded dim < num shards`. In the compiled & unbacked case, we'll often encounter dim size `u_` where `u_` can be both larger and smaller than num shards. This PR assumes such cases are shardable by default, and the implication is that strategies that shard on unbacked dimensions are included for consideration, and if selected, can lead to uneven sharding/zero-size shards at runtime. Alternatives would be 1) the current state of things: DDE and force the user to pick a path: `torch._check(size of sharded dim < or >= num shards)`, or 2) assume the non-shardable case and never include sharded strategies, unless the user picks the shardable path. More discussion in https://github.com/pytorch/pytorch/issues/165034#issuecomment-3417695068. - Lastly, testing traced redistribution decisions required using aot_eager backend, so that the collectives/ops were hardcoded (eager backend would go through DTensor.dispatch again). This seemed to require re-enabling proxy tracking during shard prop, basically reverting https://github.com/pytorch/pytorch/pull/163126. Otherwise, errors like `RuntimeError: Max(1, u2) (, 140294330350224)is not tracked with proxy for ` show up for DTensor outer strides...

The results are validated in the improved testing that the ``___dict_contains`` will be sorted based on the verbose part. The first solution was also suggested in https://fb.workplace.com/groups/1075192433118967/permalink/1650742858897252/ by sorting the ``get_leaf_guards()`` in ``construct_manager_string``. 2. The second solution will be adopted the ``OrderedSet`` in setGuards during guards construction to make sure the ``contain_dict`` are displayed as the order of being added. We decided to pursuit the second options to reduce the sorting time overhead and simplicity.

For tensors that are marked as `should_offload` and pass the verification in `can_offload()`, we modify the forward and backward graph, where in the forward graph, we offload tensors to CPU, and in the backward graph, we reload tensors to GPU. We introduce two flags: * `enable_activation_offloading` -- with this turned on, we insert offload/reload nodes to the fwd/bwd graphs. * `activation_offload_separate_stream` -- with this turned on, we wrap the offload/reload nodes in a separate stream with correct waits for e.g., data dependencies. (Note that from a "frontend" perspective, everything is the same, the only difference is that the memcpy is now moved to a separate stream, which prepares for subsequent reordering and overlapping) For an [example model](https://gist.github.com/xuanzhang816/ee2e3648123670f14ced9963858ee3b4), we have 1. baseline (i.e., no activation offloading) - 9160 MB peak memory - 157.42 ms per-iteration runtime - trace for fwd and bwd as below: image 2. AO (i.e., with `enable_activation_offloading=True`) - 7460 MB peak memory - 224.15 ms per-iteration runtime - trace for fwd and bwd as below (the "M" blocks are for Memcpy): image 3. AO on separate stream (i.e., additionally with `activation_offload_separate_stream = True`) - 7460 MB peak memory - 224.11 ms per-iteration runtime - trace for fwd and bwd as below (the "M" blocks are for Memcpy): image Pull Request resolved: https://github.com/pytorch/pytorch/pull/167880 Approved by: https://github.com/eellison --- test/dynamo/test_activation_offloading.py | 218 ++++++++ .../_activation_offloading/__init__.py | 5 + .../activation_offloading.py | 518 ++++++++++++++++++ torch/_functorch/config.py | 6 + torch/_functorch/partitioners.py | 13 + 5 files changed, 760 insertions(+) create mode 100644 test/dynamo/test_activation_offloading.py create mode 100644 torch/_functorch/_activation_offloading/__init__.py create mode 100644 torch/_functorch/_activation_offloading/activation_offloading.py diff --git a/test/dynamo/test_activation_offloading.py b/test/dynamo/test_activation_offloading.py new file mode 100644 index 0000000000000..5c228110998bd --- /dev/null +++ b/test/dynamo/test_activation_offloading.py @@ -0,0 +1,218 @@ +# Owner(s): ["oncall: pt2"] +# flake8: noqa: B950 + +from functools import partial + +import pytest + +import torch +import torch._functorch.config +from functorch.compile import ( + aot_function, + default_decompositions, + min_cut_rematerialization_partition, +) +from torch._dynamo.graph_bytecode_inputs import reset_user_object_tracking +from torch._inductor.utils import run_fw_bw_and_get_code +from torch.testing import FileCheck +from torch.testing._internal.common_utils import run_tests, TestCase +from torch.testing._internal.inductor_utils import GPU_TYPE, HAS_GPU + + +networkx = pytest.importorskip("networkx") + + +def extract_graph(fx_g, _, graph_cell): + graph_cell[0] = fx_g + return fx_g + + +def get_fw_bw_graph( + f, inps, partitioner=min_cut_rematerialization_partition, dynamic=False +): + fw_graph_cell = [None] + bw_graph_cell = [None] + aot_function( + f, + fw_compiler=partial(extract_graph, graph_cell=fw_graph_cell), + bw_compiler=partial(extract_graph, graph_cell=bw_graph_cell), + partition_fn=partitioner, + decompositions=default_decompositions, + dynamic=dynamic, + )(*inps).sum().backward() + return (fw_graph_cell[0], bw_graph_cell[0]) + + +class ActivationOffloadingTests(TestCase): + """Tests activation offloading functionality""" + + def setUp(self): + super().setUp() + + def fn(x): + return (x[0] + x[1]).sin() + (x[2] + x[3]).sin() + (x[4] + x[5]).sin() + + def mark_one_cos_for_offloading(gm, joint_inputs): + for node in gm.graph.nodes: + if node.name == "cos_1": + node.meta["should_offload"] = True + return gm + + dim = 10 + self.x = [ + torch.randn(dim, dim, requires_grad=True, device=GPU_TYPE) for _ in range(6) + ] + self.fn = fn + self.joint_custom_pass = mark_one_cos_for_offloading + + """ + The first set of tests are for the case of adding offload nodes to the fwd and bwd graphs. + """ + + @torch._functorch.config.patch(enable_activation_offloading=True) + def test_partitioner_offload(self): + torch._dynamo.reset() + torch._functorch.config.joint_custom_pass = self.joint_custom_pass + fw_graph, bw_graph = get_fw_bw_graph(self.fn, [self.x]) + + self.assertExpectedInline( + fw_graph.code.strip(), + """\ +def forward(self, primals_1, primals_2, primals_3, primals_4, primals_5, primals_6): + add = torch.ops.aten.add.Tensor(primals_1, primals_2);

This is no longer allowed; the devices must match. ``` As you can see the underlying problem is 1) we do a clone on storage 2) which under the hood calls `_copy` 3) but when we call `copy_` the fake mode turns a self, which is on "cpu", into a meta device. This PR fixes the issue by temporarily disabling dispatch when doing the deepclone.

However, some use cases like CTran require IPC functionality for multi-process GPU communication. This change introduces PYTORCH_CUDA_EXPANDABLE_SEGMENTS_IPC environment variable to allow opt-in enablement of IPC handle types for expandable segments in fbcode builds while maintaining backward compatibility. IPC is enabled by default in non-fbcode builds and disabled by default in fbcode builds (existing behavior). In both cases, it can be explicitly enabled by setting PYTORCH_CUDA_EXPANDABLE_SEGMENTS_IPC=1.
