v5.0.1 Release

v5.0.1

• Fixed bug where zero-byte allocations from Umpire were sometimes incorrectly reported as not being Umpire allocations

v5.0.0 - Sleepless in Umpire

• 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.

v4.1.2 Release

• Added workaround for incorrect nvcc compiler warning:
  "warning: missing return statement at end of non-void function"
  occuring in one Umpire's header files.

v4.1.1 Release

v4.1.1

• Fixed DynamicPoolMap deallocate to make coalesce check O(1) again.

• Initialize m_default_allocator to HOST if not set explicitly.

v4.1.0

v4.1.0

• QuickPool available via the C & Fortran APIs.

• Resources are now created on-demand when accessed for the first time.

• Peer access is no longer automatically enabled for CUDA and HIP.

• Added cmake check to deterime if build subsystem capable of ASAN.

• Fixed ASAN poisoning to limit it to what user originally requested and not
  rounded amount.

• Improved resilliance of primary pool destructors so that giving back
  previously allocated blocks to a device that has already been cleaned up
  will no longer throw an error, but instead will now be logged and ignored.

Release v4.0.1

• Fixed Umpire builds with MPI enabled

• Added missing wrapUmpire.hpp to installation directory

v4.0.0

This release is not ABI compatible with 3.x releases, hence the major version number bump. It includes a number of new features and bug fixes, including:

• Added a FILE memory resource that allocates memory using mmap'd files. This
  can be used to allocate memory from the burst buffers on machines like Sierra
  and Lassen.
• All pools now have an "alignment" parameter that can be provided to the
  constructor.
• MemoryResourceTraits now includes a resource member that can be used to
  identify the underlying resource for any Allocator.
• Bundled tpl cxxopts has been replaced by CLI11 (only used when ENABLE_TOOLS=On)
• Fixed memory leaks in DynamicPoolList, QuickPool.
• Fixed reallocate operation when called on an allocation from a pool.

v3.0.0

This release is not ABI compatible with 2.x releases, hence the major version number bump. It includes a number of new features and bug fixes, including:

• Added support for multiple GPU devices, detected and registered as "DEVICE_N"
  where N is the device number.
• Added support for capturing function backtraces with allocations.
• Added AlignedAllocator to provide aligned allocations for host memory.
• Fixed builds using -stdlib=c++
• Switched to camp::Platform: Platform::cpu is now Platform::host

v2.1.0

This minor release fixes a bug when calling reallocate with size 0. Additionally, the replay tool now supports replaying reallocate operations.

v2.0.0

This release contains a number of changes and bugfixes, as well as some API changes that have resulted in the major version number bump:

• ENABLE_DEVICE_CONST CMake option to control whether device constant memory
  is enabled. It is now disabled by default.
• DeviceAllocator that provides a pool for allocations inside GPU kernels.
• Added "unset" operations for removing CUDA memory advice.
• Extended C/Fortran API with more allocation strategies.
• NamedAllocator that allows creating a new allocator that passes allocations
  through to underlying strategy
• UMPIRE_VERSION_X are now defined as macros, rather than constexpr variables
• Fixed reallocate to properly handle case where size == 0
• AllocationStrategy constructor parameters re-ordered for consistency
