v2025.09.0

v2025.09.0

Changes Impacting Builds

This release of Umpire contains the following build requirement changes:

• Umpire now requires C++17 or later.

New Features

• Added DeviceIpcAllocator for GPU memory sharing between processes.

• Added HIP support to AllocationAdvisor.

• Added HIP support for get_device_mem_usage function.

• Extended Fortran API support:

  • Added AlignedAllocator to Fortran API.
  • Added SizeLimiter to Fortran API.
  • Added other strategies to Fortran API.
  • Added logical allocation routines to Fortran API.
  • Extended FORTRAN allocation support to 7D.
  • Added 5D Fortran allocation routines.

• Allow both shared memory implementations to be used at the same time.

Bug Fixes

• Fixed a communicator leak in HostMpi3SharedMemoryResource.

• Fixed handling of the CUDA language standard.

• Fixed HIP constant memory implementation.

v2025.03.1

New Features

• Added DeviceIpcAllocator strategy to allow interprocess device shared memory.

v2025.03.0

New Features

• Added a ResourceAwarePool which allows memory from the same pool to be used (1) across multiple device streams and (2) in a single memory space environment without the potential to cause data races.
• Added MPI3 Shared Memory Allocators which uses MPI3 capabilities for Shared Memory.
• Added a NamingShim strategy to allow users to allocate IPC shared memory without providing a name.

Bug Fixes

• Fixed a minor memory leak when using IPC Shared Memory Allocators.

Improvements

• A get_total_bytes_allocated function was implemented which returns the total amount of bytes allocated with Umpire allocators.
• The NamedAllocationStrategy can now be used with IPC Shared Memory Allocators.
• Additional documentation for Shared Memory Allocators was created and reorganized.
• Additional documentation on requirements for Windows builds was added to the cmake.

v2024.07.0

Changes Impacting Builds

This release of Umpire contains new build requirements including:

• Cmake version 3.23 or later is required.
• Camp version v2024.07.0 or later is required.

Bug Fixes

• Umpire uses Fortran_FORMAT to avoid compilation errors when using LLVM flang.

Improvements

• SYCL and Intel builds were added to Umpire`s DockerFile in addition to other builds in the Github workflow for better testing.

v2024.02.1

Bug Fixes

• Make usage of fmt header-only by default

v2024.02.0

New Features

• Allow using external fmt

Improvements

• Change default heuristic to percent_releasable_hwm(100)
• Making umpire_device a separate library
• Use GNUInstallDirs to set installation directories

Bug Fixes

• Make allocate API threadsafe
• Unroll product loop to fix overflow in Fortran wrappers
• Fix typo in HostSharedMemoryResourceImpl causing infinite loop

v2023.06.0

New Features

• Add _hwm variant of pool heuristic functions. These reallocate to the high watermark value after a coalescing, and can reduce memory overhead.

Improvements

• Support 2023 OneAPI release.

• Add HIP support to the DeviceAllocator.

Bug Fixes

• Prefix fmt macros to avoid conflicts with other libraries including fmt.

• Replace deprecated random_shuffle usage with shuffle for c++17.

• Make exported include directories relative to install prefix.

v2022.10.0

New Features

• New HIP Advise operations have been added for setting and unsetting of the
  READ_MOSTLY, PREFERRED_LOCATION, and ACCESSED_BY advice.

  For HIP versions >= 5, operations to set and unset COARSE_GRAIN has also been added.

• getCurrentSize and getTotalSize methods were added to the DeviceAllocator API.

• New event tracking has been added that can stream events to JSON (for replays)
  and SQLITE.

• UMAP allocation resource has been added.

Improvements

• Using try_get for async device operations.

Bug Fixes

• Fixed build problem for Fortan builds by properly installing the Umpire module files.

• Fixed build problem on certain configurations where the std::filesystem check was returning incorrect results.

• Instead of throwing an exception, the is_device_allocator helper function
  now returns false if the DeviceAllocator object has not yet been instantiated.

• Fixed FixedMallocPool on Windows, allowing the QuickPool allocator to be safely copied.

Build Configuration Updates

• Add UMPIRE_DISABLE_ALLOCATIONMAP_DEBUG (default is OFF) option that allows users to disable
  the AllocationMap from dumping all records when an allocation is not found in a debug build.

• Using UMPIRE_ENABLE_MPI instead of ENABLE_MPI for Umpire-specific MPI capabilities

• Using UMPIRE_ENABLE_IPC_SHARED_MEMORY instead of ENABLE_IPC_SHARED_MEMORY to indicate this is an Umpire-specific implementation feature.

v2022.03.1

This is a patch release of v2022.03 that fixes reported build errors by setting UMPIRE_ENABLE_DOCS back to OFF
by default since building documentation sets requires additional tools to build properly.
