Added

• Level 3 syrk_ex function for both C and FORTRAN but without API support for the ILP64 format.

Optimized

• Level 2 tpmv and sbmv functions.

Resolved issues

• Corrected client memory use counts for the ROCBLAS_CLIENT_RAM_GB_LIMIT environment variable.
• Fix to avoid false Clang static analysis warnings.

rocBLAS code for ROCm 7.1.1 did not change. The library was rebuilt for the updated ROCm 7.1.1 stack.

Added

• Sample for clients using OpenMP threads calling rocBLAS functions.
• gfx1103, gfx1150, and gfx1151 enabled.

Changed

• By default, the Tensile build is no longer based on tensile_tag.txt but uses the same commit from shared/tensile in the rocm-libraries repository. The rmake or install -t option can build from another local path with a different commit.

Optimized

• Improved the performance of Level 2 gemv transposed (TransA != N) for the problem sizes where m is small and n is large on gfx90a and gfx942.

Added

• Enabled gfx1150 and gfx1151.
• The ROCBLAS_USE_HIPBLASLT_BATCHED variable to independently control the batched hipblaslt backend. Set ROCBLAS_USE_HIPBLASLT_BATCHED=0 to disable batched GEMM use of the hipblaslt backend.

rocBLAS code for ROCm 6.4.4 did not change. The library was rebuilt for the updated ROCm 6.4.4 stack.

rocBLAS code for ROCm 7.0.1 did not change. The library was rebuilt for the updated ROCm 7.0.1 stack.

Added

• gfx950 support
• ROCBLAS_LAYER = 8 internal API logging for gemm debugging
• Support for AOCL 5.0 gcc build as a client reference library
• Allow PkgConfig for client reference library fallback detection

Changed

• CMAKE_CXX_COMPILER is now passed on during compilation for a Tensile build
• Change default atomics mode from allowed to not allowed

Removed

• Support code for non-production gfx targets
• rocblas_hgemm_kernel_name, rocblas_sgemm_kernel_name, and rocblas_dgemm_kernel_name API functions
• Use of warpSize as a constexpr
• Use of deprecated behavior of hipPeekLastError
• rocblas_float8.h and rocblas_hip_f8_impl.h files
• rocblas_gemm_ex3, rocblas_gemm_batched_ex3, rocblas_gemm_strided_batched_ex3 API functions

Optimized

• Optimized gemm by using gemv kernels when applicable
• Optimized gemv for small m and n with a large batch count on gfx942
• Improved the performance of Level 1 dot for all precisions and variants when N > 100000000 on gfx942
• Improved the performance of Level 1 asum and nrm2 for all precisions and variants on gfx942
• Improved the performance of Level 2 sger (single precision) on gfx942
• Improved the performance of Level 3 dgmm for all precisions and variants on gfx942

Resolved issues

• Fixed environment variable path-based logging to append multiple handle output to the same file
• Support numerics when trsm is running with rocblas_status_perf_degraded
• Fixed the build dependency installation of joblib on some operating systems
• Return rocblas_status_internal_error when rocblas_[set,get]_ [matrix,vector] is called with a host pointer in place of a device pointer
• Reduced the default verbosity level for internal GEMM backend information
• Updated from the deprecated rocm-cmake to ROCmCMakeBuildTools
• Corrected AlmaLinux gfortran package dependencies

Upcoming changes

• Deprecated the use of negative indices to indicate the default solution is being used for gemm_ex with rocblas_gemm_algo_solution_index

rocBLAS code for ROCm 6.4.3 did not change. The library was rebuilt for the updated ROCm 6.4.3 stack.

Resolved issues

• Zero imaginary portion of diagonal of C matrix for cherk/zherk for gfx90a/gfx942 with problem sizes k > 500

rocBLAS code for ROCm 6.4.1 did not change. The library was rebuilt for the updated ROCm 6.4.1 stack.
