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.

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

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.

v2022.03.0

Changes Impacting Builds

This release of Umpire contains new build requirements including:

  • C++14 is now required to build Umpire
  • CMake version 3.14 or later is required
  • The install location for umpire-config.cmake has changed from $(UMPIRE_INSTALL)/share/umpire/cmake to $(UMPIRE_INSTALL)/lib/cmake/umpire.

Changes Impacting C/Fortran

  • The CMake object library for C/FORTRAN interface has been reorganized.
    (NOTE: This is a breaking change since the include paths are now different.)
  • The C/FORTRAN interface header files have moved from umpire/interface/ to umpire/interface/c_fortran/ so including files will need to be updated in order to find them.

New Interfaces

  • Added a getDeviceAllocator function that allows users to get a DeviceAllocator object from the kernel without explicitly passing the allocator to the kernel first.
  • Added a reset function to the DeviceAllocator so that old data can be rewritten.
  • Expose PREFETCH operations registered with the MemoryOperationRegistry with a new ResourceManager::prefetch method.

Removed Interfaces

The following functions previously marked as deprecated have now been removed:

  • DynamicPoolMap and DynamicPool aliases removed
  • registerAllocator and isAllocatorRegistered removed

Fixes

  • Fixed a cmake install config issue so that now users can find a package of Umpire with a version constraint.
  • Fix ResourceManager::isAllocator to work for resources
  • Fix comparison operators for TypedAllocators
  • Fix host and device Allocator ID overlap
  • Remove null and zero-byte pool from list of valid allocators

New Configuration Options

  • The UMPIRE_ENABLE_DEVICE_ALLOCATOR option was added to control whether or not the DeviceAllocator class is included in the library. The default is "Off".

Build/Deployment Improvements

  • C/FORTRAN API is now auto generated
  • The umpire-config.cmake package is now relocatable
  • Use blt namespace for hip targets
  • Umpire CMakeList options now have UMPIRE_ prefixes and are now dependent upon corresponding BLT options.
  • Removed hardcoded -Xcompiler -mno-float128 for GCC 8+ with CUDA on PowerPC.
  • Build Doxygen documentation on ReadTheDocs.

Continuous Integration Updates

  • Add CI job with interprocess shared memory and CUDA
  • Add CI containers to allow for gcc{7,8,9}, clang{11,12}, and nvcc{10,11}
  • Add CI to check pools work with DEVICE_CONST memory

v6.0.0

Added documentation on allocator (in)accessibility as well as getAllocator usage.

Added a Release function to FixedPool and corresponding gtest in strategy_tests

Installed thirdparty exports in CMake configuration file

Replay will now display high water mark statistics per allocator.

Initial support for IPC Shared Memory via a "SHARED" resource allocator. IPC Shared memory is initially available on the Host resource and will default to the value of ENABLE_MPI.

Added get_communicator_for_allocator to get an MPI Communicator for the scope of a shared allocator.

Added Allocator::getStrategyName() to get name of the strategy used.

Added getActualHighwatermark to all pool strategies, returns the high water value of getActualSize.

Added umpire::mark_event() to mark an event during Umpire lifecycle

Added asynchronous memset and reallocate operations for CUDA and HIP.

Added support for named allocations.

DynamicPoolMap marked deprecated. QuickPool should be used instead.

Refactored pool coalesce heuristic API to return either 0 or the minimum pool size to allocate when a coalesce is to be performed. No functional change yet.

All asynchronous operations now return a camp::resources::EventProxy to avoid the overhead of creating Events when they are unused.

Removed all internal tracking, allocations are only tracked at the Allocator level.

  • Memory Resource header and source files for HIP.

  • Unified Memory support for HIP, including testing and benchmarking (temp support for Fortran).

  • Added a getParent functionality for retrieving the memory resource of an allocator.

  • Added an allocator accessibility functionality for checking if an allocator is accessible given
    a certain platform.

  • Changed enumeration names from all upper case to all lower case in order to
    avoid name collisions.

  • Fixed up broken source links in tutorial documentation.

  • registerAllocator is deprecated, addAlias should be used instead.

  • Moved backend-specific resource code out of ResourceManager and into resource::MemoryResourceRegistry.

  • Fixed accounting for number of releasable bytes in Quickpool that was causing
    coalesce operations to not work properly.
