rocSPARSE 3.0.2 for ROCm 6.0.0

Added

• Added rocsparse_inverse_permutation
• Added mixed precisions for SpVV
• Added uniform int8 precision for Gather and Scatter

Optimized

• Optimization to doti routine
• Optimization to spin-looping algorithms

Changed

• Changed rocsparse_spmv function arguments
• Changed rocsparse_xbsrmv routines function arguments
• doti, dotci, spvv, and csr2ell now require calling hipStreamSynchronize after when using host pointer mode
• Improved documentation
• Improved verbose output during argument checking on API function calls

Deprecated

• Deprecated rocsparse_spmv_ex
• Deprecated rocsparse_xbsrmv_ex routines

Removed

• Removed auto stages from spmv, spmm, spgemm, spsv, spsm, and spitsv.
• Removed rocsparse_spmm_ex routine

Fixed

• Fixed a bug in rocsparse-bench, where SpMV algorithm was not taken into account in CSR format
• Fixed the BSR/GEBSR routines bsrmv, bsrsv, bsrmm, bsrgeam, gebsrmv, gebsrmm so that block_dim==0 is considered an invalid size
• Fixed bug where passing nnz = 0 to doti or dotci did not always return a dot product of 0

rocSPARSE 2.5.4 for ROCm 5.7.1

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

rocSPARSE 2.5.4 for ROCm 5.7.0

Added

• Added more mixed precisions for SpMV, (matrix: float, vectors: double, calculation: double) and (matrix: rocsparse_float_complex, vectors: rocsparse_double_complex, calculation: rocsparse_double_complex)
• Added support for gfx940, gfx941 and gfx942

Improved

• Fixed a bug in csrsm and bsrsm

Known Issues

In csritlu0, the algorithm rocsparse_itilu0_alg_sync_split_fusion has some accuracy issues to investigate with XNACK enabled. The fallback is rocsparse_itilu0_alg_sync_split.
