rocSPARSE 3.4.0 for ROCm 6.4.0

Added

• Added support for rocsparse_matrix_type_triangular in rocsparse_spsv
• Added test filters smoke, regression, and extended for emulation tests.
• Added rocsparse_[s|d|c|z]csritilu0_compute_ex routines for iterative ILU
• Added rocsparse_[s|d|c|z]csritsv_solve_ex routines for iterative triangular solve
• Added GPU_TARGETS to replace the now deprecated AMDGPU_TARGETS in cmake files
• Added BSR format to the SpMM generic routine rocsparse_spmm

Changed

• By default, build rocsparse shared library using --offload-compress compiler option which compresses the fat binary. This significantly reduces the shared library binary size.

Optimized

• Improved the performance of rocsparse_spmm when used with row order for B and C dense matrices and the row split algorithm, rocsparse_spmm_alg_csr_row_split.
• Improved the adaptive CSR sparse matrix-vector multiplication algorithm when the sparse matrix has many empty rows at the beginning or at the end of the matrix. This improves the routines rocsparse_spmv and rocsparse_spmv_ex when the adaptive algorithm rocsparse_spmv_alg_csr_adaptive is used.
• Improved stream CSR sparse matrix-vector multiplication algorithm when the sparse matrix size (number of rows) decreases. This improves the routines rocsparse_spmv and rocsparse_spmv_ex when the stream algorithm rocsparse_spmv_alg_csr_stream is used.
• Compared to rocsparse_[s|d|c|z]csritilu0_compute, the routines rocsparse_[s|d|c|z]csritilu0_compute_ex introduce a number of free iterations. A free iteration is an iteration that does not compute the evaluation of the stopping criteria, if enabled. This allows the user to tune the algorithm for performance improvements.
• Compared to rocsparse_[s|d|c|z]csritsv_solve, the routines rocsparse_[s|d|c|z]csritsv_solve_ex introduce a number of free iterations. A free iteration is an iteration that does not compute the evaluation of the stopping criteria. This allows the user to tune the algorithm for performance improvements.
• Improved user documentation

Resolved issues

• Fixed an issue in rocsparse_spgemm, rocsparse_[s|d|c|z]csrgemm, and rocsparse_[s|d|c|z]bsrgemm where incorrect results could be produced when rocSPARSE was built with optimization level O0. This was caused by a bug in the hash tables that could allow keys to be inserted twice.
• Fixed an issue in the routine rocsparse_spgemm when using rocsparse_spgemm_stage_symbolic and rocsparse_spgemm_stage_numeric, where the routine would crash when alpha and beta were passed as host pointers and where beta != 0.
• Fixed an issue in rocsparse_bsrilu0 where the algorithm was running out of bounds of the bsr_val array.

Upcoming changes

• Deprecated rocsparse_[s|d|c|z]csritilu0_compute routines. Users should use the newly added rocsparse_[s|d|c|z]csritilu0_compute_ex routines going forward.
• Deprecated rocsparse_[s|d|c|z]csritsv_solve routines. Users should use the newly added rocsparse_[s|d|c|z]csritsv_solve_ex routines going forward.
• Deprecated AMDGPU_TARGETS using in cmake files. Users should use GPU_TARGETS going forward.
