v0.15.3

Added

• Added support to care::KeyValueSorter for sorting by both key and value.

Changed

• Algorithms returning a sum were changed to allow returning a different type to avoid integer overflow.
• Extended care::CompressArray to allow providing a list of indices to keep or to remove.

Fixed

• Removed template arguments when declaring special member functions of a template class. They are unnecessary and even disallowed by some compilers.
• Fixed several chunked loop macros.
• Fixed comparison function passed to cub/hipcub.

v0.15.2

Added

• Added parameter for creating Umpire pools with a specified alignment for allocations.

Changed

• Minimum C++ standard is now set to c++17.
• CUB submodule has been removed. CARE now defaults to the CUB shipped with the CUDA toolkit.
  A different CUB install can be used by specifying CUB_DIR.
• Updated to BLT v0.7.1
• Updated to Umpire v2025.09.0
• Updated to RAJA v2025.09.0
• Updated to CHAI v2025.09.1

Fixed

• Fixed build errors when CARE is compiled with C++20.
• Updated to nvtx3 to support CUDA 12.9 (nvtx3 still supports back to CUDA 10.0).
• Fixed build errors when CARE is configured with ENABLE_OPENMP or CARE_ENABLE_GPU_SIMULATION_MODE.
• Fixed some build warnings.

v0.15.1

Release date 2025-04-07

Added

• Added support for RAJA MultiReducers (Min/Max/Sum).

Changed

• Changed RAJA reduce policy for CUDA to RAJA::cuda_reduce_atomic.
• Rearranged template parameters of care::sortKeyValueArrays (used by care::KeyValueSorter) for ease of use

Fixed

• Only enable calls to cub::DeviceMergeSort when it is available (used by care::sortArray and care::KeyValueSorter when the type is not arithmetic)
• Fixes inputs to [hip]cub::DeviceMergeSort::StableSortKeys (used by care::sortArray when the type is not arithmetic)
• Avoids hardcoding one overload of care::sortArray to use [hip]cub::DeviceRadixSort
• Fixes a case where care::sort_uniq should not modify the input array
• Miscellaneous fixes for care::host_device_map
• Clarified documentation for care::BinarySearch
• Added missing attributes to functions for building as a shared library on Windows
• Moved helper function to be accessible when the loop fuser is disabled

Removed

• Removed dead ENABLE_PICK option (corresponding option has been removed from CHAI)

v0.15.0

Release date 2025-03-20

Added

• Added CARE_DEEP_COPY_RAW_PTR configuration option.
• Added ATOMIC_SUB, ATOMIC_LOAD, ATOMIC_STORE, ATOMIC_EXCHANGE, and ATOMIC_CAS macros.

Removed

• Removed Accessor template parameter from host_device_ptr.
• Removed NoOpAccessor and RaceConditionAccessor. It is recommended to use ThreadSanitizer (TSAN) instead to locate race conditions.
• Removed CARE_ENABLE_RACE_DETECTION configuration option.
• Removed implicit conversions between raw pointers and host_device_ptrs/host_ptrs and the corresponding CARE_ENABLE_IMPLICIT_CONVERSIONS configuration option.
• Removed make_managed_from_factory wrapper function

Changed

• Renamed host_device_ptr::getPointer to host_device_ptr::data.

Fixed

• Replaced calls to chai::ManagedArray::getPointer (previously deprecated and now removed) with calls to chai::ManagedArray::data.

Updated

• Updated to BLT v0.7.0

Full Changelog: v0.14.0...v0.14.1

v0.14.0

Release date 2024-09-11

Added

• Added default and move constructors and move assignment operator to host_device_map

Changed
