# Change Log for rocPRIM Full documentation for rocPRIM is available at [https://codedocs.xyz/ROCmSoftwarePlatform/rocPRIM/](https://codedocs.xyz/ROCmSoftwarePlatform/rocPRIM/) ## [rocPRIM-2.10.13 for ROCm 5.1.0] ### Fixed - Fixed radix sort int64_t bug introduced in [2.10.11] ### Added - Future value - Added device partition_three_way to partition input to three output iterators based on two predicates ### Changed - The reduce/scan algorithm precision issues in the tests has been resolved for half types. ### Known issues - device_segmented_radix_sort unit test failing for HIP on Windows ## [Unreleased rocPRIM-2.10.12 for ROCm 5.0.0] ### Fixed - Enable bfloat16 tests and reduce threshold for bfloat16 - Fix device scan limit_size feature - Non-optimized builds no longer trigger local memory limit errors ### Added - Added scan size limit feature - Added reduce size limit feature - Added transform size limit feature - Add block_load_striped and block_store_striped - Add gather_to_blocked to gather values from other threads into a blocked arrangement - The block sizes for device merge sorts initial block sort and its merge steps are now separate in its kernel config - the block sort step supports multiple items per thread ### Changed - size_limit for scan, reduce and transform can now be set in the config struct instead of a parameter - Device_scan and device_segmented_scan: `inclusive_scan` now uses the input-type as accumulator-type, `exclusive_scan` uses initial-value-type. - This particularly changes behaviour of small-size input types with large-size output types (e.g. `short` input, `int` output). - And low-res input with high-res output (e.g. `float` input, `double` output) - Revert old Fiji workaround, because they solved the issue at compiler side - Update README cmake minimum version number - Block sort support multiple items per thread - currently only powers of two block sizes, and items per threads are supported and only for full blocks - Bumped the minimum required version of CMake to 3.16 ### Known issues - Unit tests may soft hang on MI200 when running in hipMallocManaged mode. - device_segmented_radix_sort, device_scan unit tests failing for HIP on Windows - ReduceEmptyInput cause random faulire with bfloat16 ## [Unreleased rocPRIM-2.10.11 for ROCm 4.5.0] ### Added - Initial HIP on Windows support. See README for instructions on how to build and install. - bfloat16 support added. ### Changed - Packaging split into a runtime package called rocprim and a development package called rocprim-devel. The development package depends on runtime. The runtime package suggests the development package for all supported OSes except CentOS 7 to aid in the transition. The suggests feature in packaging is introduced as a deprecated feature and will be removed in a future rocm release. - As rocPRIM is a header-only library, the runtime package is an empty placeholder used to aid in the transition. This package is also a deprecated feature and will be removed in a future rocm release. ### Known issues - Unit tests may soft hang on MI200 when running in hipMallocManaged mode. ### Deprecated - The warp_size() function is now deprecated; please switch to host_warp_size() and device_warp_size() for host and device references respectively. ## [Unreleased rocPRIM-2.10.11 for ROCm 4.4.0] ### Added - Code coverage tools build option - Address sanitizer build option - gfx1030 support added. - Experimental [HIP-CPU](https://github.com/ROCm-Developer-Tools/HIP-CPU) support; build using GCC/Clang/MSVC on Win/Linux. It is work in progress, many algorithms still known to fail. ### Optimizations - Added single tile radix sort for smaller sizes. - Improved performance for radix sort for larger element sizes. ### Deprecated - The warp_size() function is now deprecated; please switch to host_warp_size() and device_warp_size() for host and device references respectively. ## [Unreleased rocPRIM-2.10.10 for ROCm 4.3.0] ### Fixed - Bugfix & minor performance improvement for merge_sort when input and output storage are the same. ### Added - gfx90a support added. ### Deprecated - The warp_size() function is now deprecated; please switch to host_warp_size() and device_warp_size() for host and device references respectively. ## [rocPRIM-2.10.9 for ROCm 4.2.0] ### Fixed - Size zero inputs are now properly handled with newer ROCm builds that no longer allow zero-size kernel grid/block dimensions ### Changed - Minimum cmake version required is now 3.10.2 ### Known issues - Device scan unit test currently failing due to LLVM bug. ## [rocPRIM-2.10.8 for ROCm 4.1.0] ### Fixed - Texture cache iteration support has been re-enabled. - Benchmark builds have been re-enabled. - Unique operator no longer called on invalid elements. ### Known issues - Device scan unit test currently failing due to LLVM bug. ## [rocPRIM-2.10.7 for ROCm 4.0.0] ### Added - No new features ## [rocPRIM-2.10.6 for ROCm 3.10] ### Optimizations - Updates to DPP instructions for warp shuffle ### Known issues - Benchmark builds are disabled due to compiler bug. ## [rocPRIM-2.10.5 for ROCm 3.9.0] ### Added - Added HIP cmake dependency ### Optimizations - Updates to warp shuffle for gfx10 - Disable DPP functions on gfx10++ ### Known issues - Benchmark builds are disabled due to compiler bug. ## [rocPRIM-2.10.4 for ROCm 3.8.0] ### Fixed - Fix for rocPRIM texture cache iterator ### Known issues - None ## [rocPRIM-2.10.3 for ROCm 3.7.0] ### Fixed - Package dependency correct to hip-rocclr ### Known issues - rocPRIM texture cache iterator functionality is broken in the runtime. It will be fixed in the next release. Please use the prior release if calling this function. ## [rocPRIM-2.10.2 for ROCm 3.6.0] ### Added - No new features ## [rocPRIM-2.10.1 for ROCm 3.5.1] ### Fixed - Point release with compilation fix. ## [rocPRIM-2.10.1 for ROCm 3.5.0] ### Added - Improved tests with fixed and random seeds for test data - Network interface improvements with API v3 ### Changed - Switched to hip-clang as default compiler - CMake searches for rocPRIM locally first; downloads from github if local search fails
