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
