prevent auto-converting const char * to bool in ParmParse::add (#4969)

It used to be that ParmParse::add("key", "value") will result in adding a boolean value (1) due to C++ converting pointer to bool. This is almost certainly not intended. This is now fixed.
SYCL: Add a new path for big kernels (#4952)

The SYCL kernel on Intel GPUs has a kernel parameter size limit of 2KB. If this limit is exceeded, a runtime error will occur when if AOT is off, and a compile time error will occur if AOT is on. Compiling with AOT is very time consuming. Thus we usually compile with AOT off, and this often results in run time errors.

We have implemented a workaround for this limitation. When the kernel parameter is too large, we explicitly copy the kernel function object to device memory.
Generalize SIMD Single Source Design (#4924)

This adds another template overload to ParallelForSIMD.

A typical user pattern for maximum controls so far is:
```
#ifdef AMREX_USE_SIMD
if constexpr (amrex::simd::is_vectorized<T>) {
    amrex::ParallelForSIMD<T::simd_width>(np, pushSingleParticle);
} else
#endif
{
    amrex::ParallelFor(np, pushSingleParticle);  // GPU & non-SIMD CPU
}
```
This simplifies it to:
```
amrex::ParallelForSIMD<T>(np, pushSingleParticle);
```
indicating there might be a SIMD path if T (e.g., a functor) implements it.

One can still call ParallelForSIMD with an explicit SIMD width (int), as before.

26.02

Highlights:

SpMatrix: The sparse matrix vector multiplication functionality has been extended to support non-square matrix. A matrix transpose function for amrex::SpMatrix has been been added.
Add the marching cubes algorithm of "Efficient implementation of Marching Cubes' cases with topological guarantees" by Lewiner, Lopes, Vieira & Tavares, Journal of Graphics Tools 8(2): pp. 1-15 (2003). The implementation is adapted from the source code available at http://thomas.lewiner.org/publication_page.php%EF%B9%96pubkey=marching_cubes_jgt.html. Given a signed distance function (e.g., from our STL tools), this generates a list of topologically consistent triangles.
ArrayND: The Array4 class has been generalized to N-dimensions, where N is a compile time constant.
ReduceOps.eval with BoxND. This enables the use of ReduceOps.eval() with a BoxND of any dimension. This is achieved using BoxIndexerND, just like ParallelForRNG, which also provides support for 64-bit indexing to support very large boxes.

26.01

Highlights:

Deterministic MLMG. The MLMG solver is not reproducible because it uses non-deterministic atomic operations in reflux. We now have an option to make the MLMG solver deterministic:
Add SArena: The_Arena wrapper using Gpu::freeAsync. This adds a new memory arena that is a wrapper for The_Arena but calls freeAsync in its free function. The new arena, called SArena for stream-ordered arena, replaces the PArena in the implementation of The_Async_Arena.
Generalize diffmultifab routine to allow for different BoxArrays covering the same region. (#4836)
Add amrex::Gpu::freeAsync. This adds the function amrex::Gpu::freeAsync (Arena* arena, void* mem) that can be used to free memory the next time the current GPU stream is synchronized.

Other major changes:

Parser: Fix bugs in optimization (#4866)
Add amrex::Math::exp10() (#4864)

Workaround for MPICH MPIX_Query_cuda_support assertion error (#4824)
Hypre iterative ILU features (#4818)

25.12

Highlights:

There is a new overload of partitionParticles that takes num_left as an input to skip the reduction that would compute num_left in the original function. This can be useful when combining the reduction with other operations in an effort to reduce the overhead from extra kernel launches and stream synchronizations.
We can now set the default value of amrex.the_arena_init_size with an environment variable, AMREX_THE_ARENA_INIT_SIZE. This is convenient for CI jobs.
Fix restart w/ out-of-bounds Particles. Seen on Frontier at 6000 nodes. If the particle locator decides that a particle is out-of-bounds, it used an inconsistent level for the particle in restart. Now, it uses the currently loaded level consistently, with an invalid-marked tile.
PC::make_alike<Allocator> changes the template default of make_alike<>() to use the same allocator as the creating allocator. This is a breaking change.
Add some extra room when we call PODVector::resize and reserve. By default, the extra capacity is computed as 3*sqrt(capacity), and is capped at 10%. Other strategies can be specified with the GrowthStrategy argument to PODVector resize and reserve. This helps particle codes avoid memory re-allocation.

Other major changes:

Fix compile error with Conduit + Particles (#4813)
Fix loop bounds in selectActualNeighbors (#4809)
RNG on GPU: Assertion it's not in OMP parallel region (#4799)

Fix PODVector shrink_to_fit() with nonzero size (#4748)

25.11

Highlights:

AMReX is now compatible with oneAPI 2025.03 that has deprecated a number of things such as the fsycl-device-lib flag and the mkl::sparse::set_csr_data function.
It used to be an assertion error when the number of ghost cells in the MultiFab is different from that in the VisMF file. We now allow them to be different. Note that if there are more ghost cells in the MultiFab, the extra ghost cell regions are not filled.
In amrex::UtilCreateCleanDirectory, if a directory already exists, we preserve it by renaming it to a directory whose name includes a string generated by amrex::UniqueString(). However, this string is not guaranteed to be unique. The behavior of std::rename is implementation-defined, and it may fail if the destination already exists. This happens rarely, but it does happen. We now addresse the issue by removing the existing conflicting directory before renaming. This makes the file renaming process more robust.
We have reimplemented SumBoundary. In the old approach, we make a temporary copy of the data, zero out the original data, and then perform parallel add. In the new approach that should be more efficient, we no longer need a temporary copy of the entire data. We have also added an optional argument that can be used to make SumBoundary deterministic. Note that being deterministic does not mean the data are consistent on shared nodes. For that, one still needs to call OverrideSync, or FillBounaryAndSync.

Hypre & PETSc in 1d build (#4692) Allow hypre and petsc in 1d build (#4682)

25.10

Highlights:

Add range-based for and ND to BoxIterator (#4668)

The new capability allows a range-base for loop for iterating over Box. For example
```
    for (auto iv : box.iterator()) {
        // do operations involving iv
    }
```
AMREX_ENUM: Cache String Map (#4643)

This provides significant performance improvement for AMREX_ENUM with a large number of values (e.g., > 70).
ParmParse: Add prettyPrintUsedInputs and prettyPrintUnusedInputs (#4652)

This adds two new functions to ParmParse that can be very useful.

25.09

Highlights:

amrex::callNoinline: Call given function without inline (#4606)

This new function can be used to force noinlining functions. It can be useful when it's necessary to reduce GPU kernel sizes.
Incorrect cross term sum for 2D EB terms in MLEBTensor (#4626)

This fixes a very old bug in the computation of the cross terms of the Navier-Stokes stress tensor in the 2D EB case. The bug affected AMReX based codes that use the MLEBTensor operator in linear solvers.
Add ParallelForOMP (#4595) Fix ParallelForOMP introduced in #4595 (#4604)

amrex::ParallelFor in CPU builds does not spawn OpenMP threads, because it is usually used inside coarse-grained OpenMP regions launched at the MFIter level. However, in some cases, the users may need to start OpenMP parallel regions in the loops over cells. This new function has been added for this purpose.
Add ToString function for array and tuple (#4584)

This adds a ToString function that can be used with scalars, arrays and tuples to write error messages or when debugging.

Other major changes:

EB anisotropic meshes - changes for cut_face_2d routine (#4554) EB anisotropic - set_eb_data changes (#4577) Correction to EB volume fraction for anisotropic grids (#4587) Correction to EB volume centroid for anisotropic case (#4586)

These make the necessary changes for EB generation on 3D aniostropic meshes.
SUNDIALS interface updates (#4562)

Major updates have been made to the SUNDIALS interface.
AMReX SIMD Helpers (#4520)

AMReX does not have a concept yet to help users write effective SIMD code on CPU, besides relying on auto-vectorization and pragmas, which are unreliable for any complex enough code. This PR adds initial support for portable user-code by providing build system support and an AMReX_SIMD.H header that handles includes & helper types and functions.
CMake: AMReX_FASTMATH (#4545) CMake: AMReX::Flags_FASTMATH Interface Helper Target (#4591)

Add new general compiler flag for fast-math optimizations. This does not change any defaults

25.07

Highlights:

Fix GPU communication for non-arithmetic types (#4515)

Previously communication of non-arithmetic types for GPU builds did not work if there were race conditions. This has now been fixed.
Parallel Copy with Offset (#4510)

Add new versions of ParallelCopy and ParallelAdd that effectively shift the source multifab first and then perform copy/add. Previously, one would need to use NonLocalBC::PareallelCopy, which has a relatively more complicated interface.
Add STLtools::fillSignedDistance (#4501)

This adds a new approach for computing signed distances for STL files.

25.06

Highlights:

The default constructor of amrex::RandomEngine in GPU builds has been removed to prevent a common bug where a RandomEngine object is mistakenly created on the device using the default constructor.
CArena now uses a new memory defragmentation strategy. It is known that this has caused performance regression on Frontier. A fix for this is currently under review (AMReX-Codes#4479), and it is expected in the next monthly release.
AMReX has previously defined fake MPI data types globally in non-MPI builds for convenience. Unfortunately, this can lead to conflicts with other libraries doing the same. In this release, we have put these MPI data types in non-MPI builds into the amrex namespace. This might break non-MPI builds of some application codes. To fix it, you can explicitly use these data types with using amrex::mpidatatypes. For many codes, using a new version of amrex::Initialize that does not need MPI_Comm introduced in this release can also fix the issue.

-- The configure; make; make install build approach enables linear solvers by default now.

-- MultiFab and iMultiFab now support move assignment operator. This allows for swapping two MultiFabs without deep copying. For instance, std::swap(mf1, mf2);

-- Tutorials/Amr/Advection_AmrCore changes from using Vector<unique_ptr<MultiFab>> to Vector<MultiFab>.

17.11

-- AMREX_ASSERT_WITH_MESSAGE and AMREX_ALWAYS_ASSERT_WITH_MESSAGE are new macros for assertion when it fails additional message will be printed. For example:

     AMREX_ASSERT_WITH_MESSAGE(x > y, "reason why x > y must be true");

-- amrex::Array is deprecated and replaced by amrex::Vector. Currently Array is an alias to Vector. So this should not break any codes. In the future, we will remove Array completely. Therefore it is recommended that application codes should start replacing Array with Vector. There is a script, amrex/Tools/Migration/amrex_array_to_vector.sh, to help. But use it with caution. If it is completely gibberish to you, you probably shouldn't use the script.

-- functions for printing to a file in a parallel and thread-safe manner have been added. For example:

    amrex::AllPrintToFile("output") << "Hello from rank " << rank << 
                                       " and thread " << thread << "\n";

 will print out the requested information to separate files for each 
 rank and thread.

17.10

-- Added a load balance approach to Amr/AmrLevel. The runtime parameters for this is amr.loadbalance_with_workestimates and amr.loadbalance_level0_int. The latter is for single level (i.e., amr.max_level=0) only. For multi-level runs, load balance is done during regrid and thus the load balance interval is controlled by amr.regrid_int. To use this approach, AmrLevel derivative must has a StateData for work estimates and its index is returned by virtual function int WorkEstType().

-- MFIter now supports dynamic scheduling of OpenMP threads. For example,

   for (MFIter mfi(mf, MFItInfo().SetDynamic(true).EnableTiling(tile_size);
        mfi.isValid(); ++mfi)
   { ... }

-- Added EBFluxRegister to Src/EB for refluxing and re-redistribution in EB.

-- amrex.signal_handling = 1 is a new runtime parameter that can be used to control whether AMReX should handle signals like SIGSEGV etc.
