rocSPARSE 2.0.0 for ROCm 5.0.1

rocSPARSE code for ROCm 5.0.1 is unchanged from rocSPARSE for ROCm 5.0.0. The library was rebuilt for the updated ROCm 5.0.1 stack.

rocSPARSE 2.0.0 for ROCm 5.0.0

Added

• csrmv, coomv, ellmv, hybmv for (conjugate) transposed matrices
• csrmv for symmetric matrices

Changed

• spmm_ex is now deprecated and will be removed in the next major release

Improved

• Optimization for gtsv

rocSPARSE 1.22.2 for ROCm 4.5.2

rocSPARSE code for ROCm 4.5.2 is unchanged from rocSPARSE for ROCm 4.5.0. The library was rebuilt for the updated ROCm 4.5.2 stack.

rocSPARSE 1.22.2 for ROCm 4.5.0

Added

• Triangular solve for multiple right-hand sides using BSR format
• SpMV for BSRX format
• SpMM in CSR format enhanced to work with transposed A
• Matrix coloring for CSR matrices
• Added batched tridiagonal solve (gtsv_strided_batch)
• SpMM for BLOCKED ELL format
• Generic routines for SpSV and SpSM
• Enabling beta support for Windows 10
• Additional atomic based algorithms for SpMM in COO format
• Extended version of SpMM
• Additional algorithm for SpMM in CSR format

Changed

• Packaging split into a runtime package called rocsparse and a development package called rocsparse-devel. The development package depends on runtime. The runtime package suggests the development package for all supported OSes except CentOS 7 to aid in the transition. The suggests feature in packaging is introduced as a deprecated feature and will be removed in a future rocm release.

Improved

• Fixed a bug with gemvi on Navi21
• Fixed a bug with adaptive csrmv
• Optimization for pivot based gtsv

Known Issues

• none
