Changelog for rocSPARSE

Documentation for rocSPARSE is available at https://rocm.docs.amd.com/projects/rocSPARSE/en/latest/.

(Unreleased) rocSPARSE 5.0.0

Added

• Added Blocked ELL format support to the rocsparse_dense_to_sparse routine, including the new rocsparse_bell_set_pointers function to set the Blocked ELL array pointers.
• Added CSC format support to rocsparse_spsv and rocsparse_sptrsv.
• Added CSC format support to rocsparse_spsm and rocsparse_sptrsm.

Changed

• rocsparse_spmm with CSR/CSC and the default algorithm (rocsparse_spmm_alg_default or rocsparse_spmm_alg_csr) now automatically selects a load-balanced (nnz-split) kernel for strongly skewed matrices (those containing a single very long row for CSR, or column for transposed CSC). Behavior is unchanged for non-skewed matrices and for explicit algorithm choices (rocsparse_spmm_alg_csr_row_split, rocsparse_spmm_alg_csr_nnz_split, rocsparse_spmm_alg_csr_merge_path).

Resolved issues

• Fixed an issue with rocsparse_spmm, which produced incorrect results for the Blocked ELL sparse format.

Removed

• The deprecated rocsparse_indextype_u16 enum.

Deprecated

• Deprecated the rocsparse_spildlt0_input_diag enum value. It was used to dump the diagonal D of the ILDLT(0) factorization, which is now stored in-place on the diagonal entries of the L factor.

rocSPARSE 4.7.0 for ROCm 7.14

Added

• Added the rocsparse_spildlt0 routine for incomplete LDL' factorization with zero fill-in (ILDLT(0)) for symmetric (real) or hermitian (complex) sparse matrices in CSR format, with strided batched computations enabled.

Upcoming changes

• Deprecated the rocsparse_indextype_u16 index type. It is no longer supported and will be removed in a future release. Users should use rocsparse_indextype_i32 or rocsparse_indextype_i64 going forward.

Known issues

• The HIP graph capture/launch path for the factorization routines bsric0, bsrilu0, csric0 and csrilu0 can fail with hipErrorOutOfMemory at hipGraphLaunch on memory-constrained GPUs such as the gfx110X family. The corresponding graph_test cases are marked known_bug and excluded from the standard test suites until the fix lands.

rocSPARSE 4.6.0 for ROCm 7.13.0

Added

• Added rocsparse_handle_create to create a handle associated with a user-provided stream. All internal device memory allocation and initialization are stream-ordered on that stream, so handle creation never blocks the calling thread or other GPU streams.
• Added rocsparse_handle_destroy to destroy a handle created by rocsparse_handle_create, with an optional error descriptor argument.
• Added the rocsparse_create_const_bsr_descr routine for creating a const sparse BSR matrix descriptor.
• Added the rocsparse_spic0 and rocsparse_spilu0 routines for incomplete factorizations, with strided batched computations enabled.
• Added the rocsparse_sptrsv_descr_create and the rocsparse_sptrsv_descr_destroy routines.
• Added the rocsparse_singularity enumeration.
• Added the rocsparse_sptrsv_output_singularity and the rocsparse_sptrsv_output_singularity_position in rocsparse_sptrsv_output.
• Added the strided batched computations for rocsparse_sptrsv.

Optimized

• Significant performance improvement for rocsparse_Xgtsv_no_pivot_strided_batch.
• Significant performance improvement for rocsparse_Xgtsv_no_pivot.

Resolved issues

• Fixed incorrect usage of __syncthreads in bsrmm, csrmm (row_split), and csritilu0x
• Fixed incorrect usage of __syncthreads in csx2dense, dense2csx, prune_dense2csr, csrcolor, and csrmm (nnz_split)
• Fixed rocsparse_[s|d|c|z]csric0 where rocsparse_status_invalid_value was being returned when the maximum number of non-zeros in any row is between 513 and 1024.
• Fixed compilation when using --rocsparse_ILP64
• Fixed off-by-one heap-buffer-overflow in temporary buffer allocation for rocsparse_csrsort, rocsparse_check_matrix_csr, and rocsparse_check_matrix_gebsr (and their delegating routines rocsparse_cscsort, rocsparse_coosort, rocsparse_check_matrix_csc, and rocsparse_check_matrix_gebsc) where the shift_offsets_kernel temp buffer was sized for m elements instead of m+1.
• Fixed incorrect usage of rocsparse_conj in bsric0 for complex matrices
• Fixed double-free and use-after-free in rocsparse_copy_mat_info for csritsv info, where the owned ptr_end device buffer was copied shallowly and the pivot/position metadata was copied using the destination's (invalid) index type instead of the source's.
• Fixed the --memstat build, where tracked allocation call sites passing typed T** pointers (for example csrmv wg_flags and the HYB index buffers) failed to compile against the void** allocation entry points.

Removed

• The deprecated C++14 support, which is no longer supported by the rocPRIM dependency.

rocSPARSE 4.5.0 for ROCm 7.12.0

Added

• Added --show-skipped and --hide-skipped command-line options to rocsparse-test to control whether skipped test output is displayed.
• For sparse matrix vector product (rocsparse_spmv), when using rocsparse_spmv_alg_default, the routine now automatically falls back to a supported algorithm depending on the sparse matrix format and requested operation. For example, CSR format with transposed operations or CSC format with non-transposed operations will fall back to an appropriate algorithm.

Changed

• Use std::hypot in rocsparse_complex_num<T>::abs function.
• Non-YAML tests (bfloat16, complex_types, atomic_add) are now automatically skipped when running rocsparse-test with the --yaml filter, and skipped test output is hidden by default in this mode.

Resolved issues

• Fix issue in rocsparse_[s|d|c|z]gebsrmv routine where incorrect results could sometimes be returned.
• Fix issue in rocsparse_[s|d|c|z]bsrxmv routine where out-of-bounds memory reads can occur in the single precision bsrxmv kernels when block_dim equals 5 or 8.

rocSPARSE 4.4.0 for ROCm 7.11.0

Added

• Added brain half float mixed precision to rocsparse_spmv where A, X, and Y use bfloat16 and the compute type use float.
• Added half float mixed precision to rocsparse_spmv where A, X, and Y use float16 and the compute type use float.
• Added float16 and bfloat16 output support for level 3 functions (rocsparse_spmm, rocsparse_spgemm). This enables mixed precision workflows where the output matrix C can use float16 or bfloat16 types.
• gfx1150, gfx1152 and gfx1153 enabled.
• Added the debian, almalinux, rockylinux, and oraclelinux OS names to install script.

rocSPARSE 4.3.0 for ROCm 7.10.0

Added

• Added rocsparse_spmv_set_extra and rocsparse_spmv_clear_extra functions to enable residual computation within SpMV operations. These functions allow setting additional gamma scalars and z vectors for fused computations of the form y = alpha * op(A) * x + beta * y + sum(gamma_i * z_i), enabling efficient residual calculations like r = b - A * x.

rocSPARSE 4.2.0 for ROCm 7.2.0

Added

• Added sliced ELL format support to the rocsparse_spmv routine.
• Added the rocsparse_sptrsv and rocsparse_sptrsm routines for triangular solve.
• Added the --clients-only option to the install.sh and rmake.py scripts to only build the clients for a version of rocSPARSE that is already installed.
• Added nnz split algorithm rocsparse_spmv_alg_csr_nnzsplit to rocsparse_spmv. This algorithm might be superior to the existing adaptive algorithm rocsparse_spmv_alg_csr_adaptive when running the computation a small number of times because it avoids paying the analysis cost of the adaptive algorithm.

Changed

• Make rocBLAS a requirement when it's requested when building from source. Previously, rocBLAS was not used if it could not be found. To opt out of using rocblas when building from source, use the --no-rocblas option with the install.sh or rmake.py build scripts.

Optimized

• Significantly improved the rocsparse_sddmm routine when using CSR format, especially as the number of columns in the dense A matrix (or rows in the dense B matrix) increase.
• Improved the user documentation.

Resolved issues

• Fix the rmake.py build script to properly handle auto and all options when selecting offload targets.
• Fix building rocSPARSE with the install script on centOS 9.
• Fix std::fma casting in host routines to properly deduce types. This could have previously caused compilation failures when building from source.

rocSPARSE 4.1.0 for ROCm 7.1.0

Added

• Added brain half float mixed precision to rocsparse_axpby where X and Y use bfloat16 and result and the compute type use float.
• Added brain half float mixed precision to rocsparse_spvv where X and Y use bfloat16 and result and the compute type use float.
• Added brain half float mixed precision to rocsparse_spmv where A and X use bfloat16 and Y and the compute type use float.
• Added brain half float mixed precision to rocsparse_spmm where A and B use bfloat16 and C and the compute type use float.
• Added brain half float mixed precision to rocsparse_sddmm where A and B use bfloat16 and C and the compute type use float.
• Added brain half float mixed precision to rocsparse_sddmm where A and B and C use bfloat16 and the compute type use float.
• Added half float mixed precision to rocsparse_sddmm where A and B and C use float16 and the compute type use float.
• Added brain half float uniform precision to rocsparse_scatter and rocsparse_gather routines.

Optimized

• Improved the user documentation.

Upcoming changes

• Deprecate trace, debug, and bench logging using environment variable ROCSPARSE_LAYER.

rocSPARSE 4.0.2 for ROCm 7.0.0

Added

• Adds SpGEAM generic routine for computing sparse matrix addition in CSR format
• Adds v2_SpMV generic routine for computing sparse matrix vector multiplication. As opposed to the deprecated rocsparse_spmv routine, this routine does not use a fallback algorithm if a non-implemented configuration is encountered and will return an error in such a case. For the deprecated routine rocsparse_spmv, the user can enable warning messages in situations where a fallback algorithm is used by either calling upfront the routine rocsparse_enable_debug or exporting the variable ROCSPARSE_DEBUG (with the shell command export ROCSPARSE_DEBUG=1).
• Adds half float mixed precision to rocsparse_axpby where X and Y use float16 and result and the compute type use float
• Adds half float mixed precision to rocsparse_spvv where X and Y use float16 and result and the compute type use float
• Adds half float mixed precision to rocsparse_spmv where A and X use float16 and Y and the compute type use float
• Adds half float mixed precision to rocsparse_spmm where A and B use float16 and C and the compute type use float
• Adds half float mixed precision to rocsparse_sddmm where A and B use float16 and C and the compute type use float
• Adds half float uniform precision to rocsparse_scatter and rocsparse_gather routines
• Adds half float uniform precision to rocsparse_sddmm routine
• Added rocsparse_spmv_alg_csr_rowsplit algorithm.
• Added support for gfx950
• Add ROC-TX instrumentation support in rocSPARSE (not available on Windows or in the static library version on Linux).
• Added the almalinux OS name to correct the gfortran dependency

Changed

• Switch to defaulting to C++17 when building rocSPARSE from source. Previously rocSPARSE was using C++14 by default.

Optimized

• Reduced the number of template instantiations in the library to further reduce the shared library binary size and improve compile times
• Allow SpGEMM routines to use more shared memory when available. This can speed up performance for matrices with a large number of intermediate products.
• Use of the rocsparse_spmv_alg_csr_adaptive or rocsparse_spmv_alg_csr_default algorithms in rocsparse_spmv to perform transposed sparse matrix multiplication (C=alpha*A^T*x+beta*y) resulted in unnecessary analysis on A and needless slowdown during the analysis phase. This has been fixed by skipping the analysis when performing the transposed sparse matrix multiplication.
• Improved the user documentation

Resolved issues

• Fixed an issue in the public headers where extern "C" was not wrapped by #ifdef __cplusplus, which caused failures when building C programs with rocSPARSE.
• Fixed a memory access fault in the rocsparse_Xbsrilu0 routines.
• Fixed failures that could occur in rocsparse_Xbsrsm_solve or rocsparse_spsm with BSR format when using host pointer mode.
• Fixed ASAN compilation failures
• Fixed failure that occurred when using const descriptor rocsparse_create_const_csr_descr with the generic routine rocsparse_sparse_to_sparse. Issue was not observed when using non-const descriptor rocsparse_create_csr_descr with rocsparse_sparse_to_sparse.
• Fixed a memory leak in the rocsparse handle

Removed

• The deprecated rocsparse_spmv_ex routine
• The deprecated rocsparse_sbsrmv_ex, rocsparse_dbsrmv_ex, rocsparse_cbsrmv_ex, and rocsparse_zbsrmv_ex routines
• The deprecated rocsparse_sbsrmv_ex_analysis, rocsparse_dbsrmv_ex_analysis, rocsparse_cbsrmv_ex_analysis, and rocsparse_zbsrmv_ex_analysis routines

Upcoming changes

• Deprecated the rocsparse_spmv routine. Users should use the rocsparse_v2_spmv routine going forward.
• Deprecated rocsparse_spmv_alg_csr_stream algorithm. Users should use the rocsparse_spmv_alg_csr_rowsplit algorithm going forward.
• Deprecated the rocsparse_itilu0_alg_sync_split_fusion algorithm. Users should use one of rocsparse_itilu0_alg_async_inplace, rocsparse_itilu0_alg_async_split, or rocsparse_itilu0_alg_sync_split going forward.

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 compilation error resulting from incorrectly using reinterpret_cast to cast away a const qualifier in the rocsparse_complex_num constructor. See https://github.com/ROCm/rocSPARSE/issues/434 for more information.

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.

Known issues

• Under certain conditions, rocSPARSE might fail to compile with ASAN on Ubuntu 22.04.

• 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 occurred when n >= 65536.
