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

rocBLAS 2.45.0 for ROCm 5.3.0

Added

• install.sh option --upgrade_tensile_venv_pip to upgrade Pip in Tensile Virtual Environment. The corresponding CMake option is TENSILE_VENV_UPGRADE_PIP.
• install.sh option --relocatable or -r adds rpath and removes ldconf entry on rocBLAS build.
• install.sh option --lazy-library-loading to enable on-demand loading of tensile library files at runtime to speedup rocBLAS initialization.
• Support for RHEL9 and CS9.
• Added Numerical checking routine for symmetric, Hermitian, and triangular matrices, so that they could be checked for any numerical abnormalities such as NaN, Zero, infinity and denormal value.

Optimizations

• trmm_outofplace performance improvements for all sizes and data types using block-recursive algorithm.
• herkx performance improvements for all sizes and data types using block-recursive algorithm.
• syrk/herk performance improvements by utilising optimised syrkx/herkx code.
• symm/hemm performance improvements for all sizes and datatypes using block-recursive algorithm.

Changed

• Unifying library logic file names: affects HBH (->HHS_BH), BBH (->BBS_BH), 4xi8BH (->4xi8II_BH). All HPA types are using the new naming convention now.
• Level 3 function 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.
• Level 1, 2, and 3 function argument checking for enums is now more rigorously matching legacy BLAS so returns rocblas_status_invalid_value if arguments do not match the accepted subset.
• Add quick-return for internal trmm and gemm template functions.
• Moved function block sizes to a shared header file.
• Level 1, 2, and 3 functions use rocblas_stride datatype for offset.
• Modified the matrix and vector memory allocation in our test infrastructure for all Level 1, 2, 3 and BLAS_EX functions.
• Added specific initialization for symmetric, Hermitian, and triangular matrix types in our test infrastructure.
• Added NaN tests to the test infrastructure for the rest of Level 3, BLAS_EX functions.

Fixed

• Improved logic to #include vs <experimental/filesystem>.
• install.sh -s option to build rocblas as a static library.
• dot function now sets the device results asynchronously for N <= 0

Deprecated

• is_complex helper is now deprecated. Use rocblas_is_complex instead.
• The enum truncate_t and the value truncate is now deprecated and will removed from the ROCm release 6.0. It is replaced by rocblas_truncate_t and rocblas_truncate, respectively. The new enum rocblas_truncate_t and the value rocblas_truncate could be used from this ROCm release for an easy transition.

Removed

• install.sh options --hip-clang , --no-hip-clang, --merge-files, --no-merge-files are removed.

rocBLAS 2.44.0 for ROCm 5.2.3

rocBLAS code for ROCm 5.2.3 did not change. The library was rebuilt for the updated ROCm 5.2.3 stack.

rocBLAS code for ROCm 5.2.1 did not change. The library was rebuilt for the updated ROCm 5.2.1 stack.

rocBLAS 2.44.0 for ROCm 5.2.0

Added

• Packages for test and benchmark executables on all supported OSes using CPack.
• Added Denormal number detection to the Numerical checking helper function to detect denormal/subnormal numbers in the input and the output vectors of rocBLAS level 1 and 2 functions.
• Added Denormal number detection to the Numerical checking helper function to detect denormal/subnormal numbers in the input and the output general matrices of rocBLAS level 2 and 3 functions.
• Added NaN initialization tests to the yaml files of Level 2 rocBLAS batched and strided-batched functions for testing purposes.
• Added memory allocation check to avoid disk swapping during rocblas-test runs by skipping tests.

Optimizations

• Improved performance of non-batched and batched her2 for all sizes and data types.
• Improved performance of non-batched and batched amin for all data types using shuffle reductions.
• Improved performance of non-batched and batched amax for all data types using shuffle reductions.
• Improved performance of trsv for all sizes and data types.

Changed

• Modifying gemm_ex for HBH (High-precision F16). The alpha/beta data type remains as F32 without narrowing to F16 and expanding back to F32 in the kernel. This change prevents rounding errors due to alpha/beta conversion in situations where alpha/beta are not exactly represented as an F16.
• Modified non-batched and batched asum, nrm2 functions to use shuffle instruction based reductions.
• For gemm, gemm_ex, gemm_ex2 internal API use rocblas_stride datatype for offset.
• For symm, hemm, syrk, herk, dgmm, geam internal API use rocblas_stride datatype for offset.
• AMD copyright year for all rocBLAS files.
• For gemv (transpose-case), typecasted the 'lda'(offset) datatype to size_t during offset calculation to avoid overflow and remove duplicate template functions.

Fixed

• For function her2 avoid overflow in offset calculation.
• For trsm when alpha == 0 and on host, allow A to be nullptr.
• Fixed memory access issue in trsv.
• Fixed git pre-commit script to update only AMD copyright year.
• Fixed dgmm, geam test functions to set correct stride values.
• For functions ssyr2k and dsyr2k allow trans == rocblas_operation_conjugate_transpose.
• Fixed compilation error for clients-only build.

Removed

• Remove Navi12 (gfx1011) from fat binary.
