rocBLAS 5.0.0 for ROCm 7.0.0

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
