rocSPARSE 3.3.0 for ROCm 6.3.1

rocSPARSE code for ROCm 6.3.1 did not change. The library was rebuilt for the updated ROCm 6.3.1 stack.

rocSPARSE 3.3.0 for ROCm 6.3.0

Added

• Add rocsparse_create_extract_descr, rocsparse_destroy_extract_descr, rocsparse_extract_buffer_size, rocsparse_extract_nnz, and rocsparse_extract APIs to allow extraction of the upper or lower part of sparse CSR or CSC matrices.
• Support for the gfx1151, gfx1200, and gfx1201 architectures.

Changed

• Change the default compiler from hipcc to amdclang in install script and cmake files.
• Change address sanitizer build targets so that only gfx908:xnack+, gfx90a:xnack+, gfx940:xnack+, gfx941:xnack+, and gfx942:xnack+ are built when BUILD_ADDRESS_SANITIZER=ON is configured.

Optimized

• Improved user documentation

Resolved issues

• Fixed the csrmm merge path algorithm so that diagonal is clamped to the correct range.
• Fixed a race condition in bsrgemm that could on rare occasions cause incorrect results.
• Fixed an issue in hyb2csr where the CSR row pointer array was not being properly filled when n=0, coo_nnz=0, or ell_nnz=0.
• Fixed scaling in rocsparse_Xhybmv when only performing y=beta*y, for example, where alpha==0 in y=alpha*Ax+beta*y.
• Fixed rocsparse_Xgemmi failures when the y grid dimension is too large. This occured when n >= 65536.
• Fixed the gfortran dependency for the azurelinux operating system.

rocSPARSE 3.2.0 for ROCm 6.2.0

Additions

• New Merge-Path algorithm to SpMM, supporting CSR format
• SpSM now supports row order
• rocsparseio I/O functionality has been added to the library
