HipBLAS Versions Save

hipBLAS code for ROCm 6.1.1 did not change. The library was rebuilt for the updated ROCm 6.1.1 stack.

Additions

• New build option to automatically use hipconfig --platform to determine HIP platform
• Level 1 functions have additional ILP64 API for both C and Fortran (_64 name suffix) with int64_t function arguments
• New functions hipblasGetMathMode and hipblasSetMathMode

Deprecations

• USE_CUDA build option; use HIP_PLATFORM=amd or HIP_PLATFORM=nvidia to override hipconfig

Changes

• Some Level 2 function argument names have changed from m to n to match legacy BLAS; there was no change in implementation.
• Updated client code to use YAML-based testing
• Renamed .doxygen and .sphinx folders to doxygen and sphinx, respectively
• Added CMake support for documentation

hipBLAS code for ROCm 6.0.2 did not change. The library was rebuilt for the updated ROCm 6.0.2 stack.

Added

• added option to define HIPBLAS_USE_HIP_BFLOAT16 to switch API to use hip_bfloat16 type
• added hipblasGemmExWithFlags API

Deprecated

• hipblasDatatype_t is deprecated and will be removed in a future release and replaced with hipDataType
• hipblasComplex and hipblasDoubleComplex are deprecated and will be removed in a future release and replaced with hipComplex and hipDoubleComplex
• use of hipblasDatatype_t for hipblasGemmEx for compute-type is deprecated and will be replaced with hipblasComputeType_t in a future release

Removed

• hipblasXtrmm that calculates B <- alpha * op(A) * B is removed and replaced with hipblasXtrmm that calculates C <- alpha * op(A) * B

hipBLAS code for ROCm 5.7.1 did not change. The library was rebuilt for the updated ROCm 5.7.1 stack.

Changed

• updated documentation requirements

Dependencies

• dependency rocSOLVER now depends on rocSPARSE

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

Changed

• added const qualifier to hipBLAS functions (swap, sbmv, spmv, symv, trsm) where missing

Removed

• removed support for deprecated hipblasInt8Datatype_t enum
• removed support for deprecated hipblasSetInt8Datatype and hipblasGetInt8Datatype functions

Deprecated

• in-place trmm is deprecated. It will be replaced by trmm which includes both in-place and out-of-place functionality

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

Added

• added option to opt-in to use __half for hipblasHalf type in the API for c++ users who define HIPBLAS_USE_HIP_HALF
• added scripts to plot performance for multiple functions
• data driven hipblas-bench and hipblas-test execution via external yaml format data files
• client smoke test added for quick validation using command hipblas-test --yaml hipblas_smoke.yaml

Fixed

• fixed datatype conversion functions to support more rocBLAS/cuBLAS datatypes
• fixed geqrf to return successfully when nullptrs are passed in with n == 0 || m == 0
• fixed getrs to return successfully when given nullptrs with corresponding size = 0
• fixed getrs to give info = -1 when transpose is not an expected type
• fixed gels to return successfully when given nullptrs with corresponding size = 0
• fixed gels to give info = -1 when transpose is not in ('N', 'T') for real cases or not in ('N', 'C') for complex cases

Changed

• changed reference code for Windows to OpenBLAS
• hipblas client executables all now begin with hipblas- prefix
