hipCUB 3.1.0 for ROCm 6.1.5

hipCUB code for ROCm 6.1.5 did not change. The library was rebuilt for the updated ROCm 6.1.5 stack.

hipCUB 3.1.0 for ROCm 6.1.2

hipCUB code for ROCm 6.1.2 did not change. The library was rebuilt for the updated ROCm 6.1.2 stack.

hipCUB 3.1.0 for ROCm 6.1.1

hipCUB code for ROCm 6.1.1 did not change. The library was rebuilt for the updated ROCm 6.1.1 stack.

hipCUB 3.1.0 for ROCm 6.1.0

Changed

• CUB backend references CUB and Thrust version 2.1.0.
• Updated HIPCUB_HOST_WARP_THREADS macro definition to match host_warp_size changes from rocPRIM 3.0.
• Implemented __int128_t and __uint128_t support for radix_sort.

Fixed

• Fixed build issues with rmake.py on Windows when using VS 2017 15.8 or later due to a breaking fix with extended aligned storage.

Added

• Added interface DeviceMemcpy::Batched for batched memcpy from rocPRIM and CUB.

hipCUB 3.0.0 for ROCm 6.0.2

hipCUB code for ROCm 6.0.2 did not change. The library was rebuilt for the updated ROCm 6.0.2 stack.

hipCUB 3.0.0 for ROCm 6.0.0

Changed

• Removed DOWNLOAD_ROCPRIM, forcing rocPRIM to download can be done with DEPENDENCIES_FORCE_DOWNLOAD.

hipCUB 2.13.1 for ROCm 5.7.1

hipCUB code for ROCm 5.7.1 did not change. The library was rebuilt for the updated ROCm 5.7.1 stack.

hipCUB 2.13.1 for ROCm 5.7.0

Changed

• CUB backend references CUB and Thrust version 2.0.1.
• Fixed DeviceSegmentedReduce::ArgMin and DeviceSegmentedReduce::ArgMax by returning the segment-relative index instead of the absolute one.
• Fixed DeviceSegmentedReduce::ArgMin for inputs where the segment minimum is smaller than the value returned for empty segments. An equivalent fix is applied to DeviceSegmentedReduce::ArgMax.

Known Issues

• debug_synchronous no longer works on CUDA platform. CUB_DEBUG_SYNC should be used to enable those checks.
• DeviceReduce::Sum does not compile on CUDA platform for mixed extended-floating-point/floating-point InputT and OutputT types.
• DeviceHistogram::HistogramEven fails on CUDA platform for [LevelT, SampleIteratorT] = [int, int].
• DeviceHistogram::MultiHistogramEven fails on CUDA platform for [LevelT, SampleIteratorT] = [int, int/unsigned short/float/double] and [LevelT, SampleIteratorT] = [float, double].
