rocBLAS code for ROCm 5.6.1 did not change. The library was rebuilt for the updated ROCm 5.6.1 stack.

rocBLAS 3.0.0 for ROCm 5.6.0

Optimizations

• Improved performance of Level 2 rocBLAS GEMV on gfx90a GPU for non-transposed problems having small matrices and larger batch counts. Performance enhanced for problem sizes when m and n <= 32 and batch_count >= 256.
• Improved performance of rocBLAS syr2k for single, double, and double-complex precision, and her2k for double-complex precision. Slightly improved performance for general sizes on gfx90a.

Added

• Added bf16 inputs and f32 compute support to Level 1 rocBLAS Extension functions axpy_ex, scal_ex and nrm2_ex.

Deprecated

• trmm inplace is deprecated. It will be replaced by trmm that has both inplace and out-of-place functionality
• rocblas_query_int8_layout_flag() is deprecated and will be removed in a future release
• rocblas_gemm_flags_pack_int8x4 enum is deprecated and will be removed in a future release
• rocblas_set_device_memory_size() is deprecated and will be replaced by a future function rocblas_increase_device_memory_size()
• rocblas_is_user_managing_device_memory() is deprecated and will be removed in a future release

Removed

• is_complex helper was deprecated and now removed. Use rocblas_is_complex instead.
• The enum truncate_t and the value truncate was deprecated and now removed from. It was replaced by rocblas_truncate_t and rocblas_truncate, respectively.
• rocblas_set_int8_type_for_hipblas was deprecated and is now removed.
• rocblas_get_int8_type_for_hipblas was deprecated and is now removed.

Dependencies

• build only dependency on python joblib added as used by Tensile build
• fix for cmake install on some OS when performed by install.sh -d --cmake_install

Fixed

• make trsm offset calculations 64 bit safe

Changed

• refactor rotg test code

rocBLAS 2.47.0 for ROCm 5.5.1

rocBLAS code for ROCm 5.5.1 did not change. The library was rebuilt for the updated ROCm 5.5.1 stack.

rocBLAS 2.47.0 for ROCm 5.5.0

Added

• added functionality rocblas_geam_ex for matrix-matrix minimum operations
• added HIP Graph support as beta feature for rocBLAS Level 1, Level 2, and Level 3(pointer mode host) functions
• added beta features API. Exposed using compiler define ROCBLAS_BETA_FEATURES_API
• added support for vector initialization in the rocBLAS test framework with negative increments
• added windows build documentation for forthcoming support using ROCm HIP SDK
• added scripts to plot performance for multiple functions

Optimizations

• improved performance of Level 2 rocBLAS GEMV for float and double precision. Performance enhanced by 150-200% for certain problem sizes when (m==n) measured on a gfx90a GPU.
• improved performance of Level 2 rocBLAS GER for float, double and complex float precisions. Performance enhanced by 5-7% for certain problem sizes measured on a gfx90a GPU.
• improved performance of Level 2 rocBLAS SYMV for float and double precisions. Performance enhanced by 120-150% for certain problem sizes measured on both gfx908 and gfx90a GPUs.

Fixed

• fixed setting of executable mode on client script rocblas_gentest.py to avoid potential permission errors with clients rocblas-test and rocblas-bench
• fixed deprecated API compatibility with Visual Studio compiler
• fixed test framework memory exception handling for Level 2 functions when the host memory allocation exceeds the available memory

Changed

• install.sh internally runs rmake.py (also used on windows) and rmake.py may be used directly by developers on linux (use --help)
• rocblas client executables all now begin with rocblas- prefix

Removed

• install.sh removed options -o --cov as now Tensile will use the default COV format, set by cmake define Tensile_CODE_OBJECT_VERSION=default

rocBLAS 2.46.0 for ROCm 5.4.4

rocBLAS code for ROCm 5.4.4 did not change. The library was rebuilt for the updated ROCm 5.4.4 stack.

rocBLAS 2.46.0 for ROCm 5.4.3

rocBLAS code for ROCm 5.4.3 did not change. The library was rebuilt for the updated ROCm 5.4.3 stack.

rocBLAS 2.46.0 for ROCm 5.4.2

rocBLAS code for ROCm 5.4.2 did not change. The library was rebuilt for the updated ROCm 5.4.2 stack.

rocBLAS 2.46.0 for ROCm 5.4.1

rocBLAS code for ROCm 5.4.1 did not change. The library was rebuilt for the updated ROCm 5.4.1 stack.

rocBLAS 2.46.0 for ROCm 5.4.0

Added

• client smoke test dataset added for quick validation using command rocblas-test --yaml rocblas_smoke.yaml
• Added stream order device memory allocation as a non-default beta option.

Optimized

• Improved trsm performance for small sizes by using a substitution method technique
• Improved syr2k and her2k performance significantly by using a block-recursive algorithm

Changed

• Level 2, Level 1, and Extension functions: argument checking when the handle is set to rocblas_pointer_mode_host now returns the status of rocblas_status_invalid_pointer only for pointers that must be dereferenced based on the alpha and beta argument values. With handle mode rocblas_pointer_mode_device only pointers that are always dereferenced regardless of alpha and beta values are checked and so may lead to a return status of rocblas_status_invalid_pointer. This improves consistency with legacy BLAS behaviour.
• Add variable to turn on/off ieee16/ieee32 tests for mixed precision gemm
• Allow hipBLAS to select int8 datatype
• Disallow B == C && ldb != ldc in rocblas_xtrmm_outofplace

Fixed

• FORTRAN interfaces generalized for FORTRAN compilers other than gfortran
• fix for trsm_strided_batched rocblas-bench performance gathering
• Fix for rocm-smi path in commandrunner.py script to match ROCm 5.2 and above
