Summary: Shared memory parallel sparse matrix and sparse BLAS library |
librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.
LGPL-3.0-or-later
* Sat Jul 16 2022 Jan Engelhardt <jengelh@inai.de> - Update to release 1.3.0.1 * rsb.h: additional input checks in rsb_mtx_rndr(). * rsb.hpp: additional input checks in the C++ wrappers. * No more unaligned memory access with `rsbench - -read-performance-record` (fix for armhf,sparc64 architectures). * Thu Apr 21 2022 Jan Engelhardt <jengelh@inai.de> - Update to release 1.3.0.0 * Considerably improved performance of rsb_spmm()/usmm() via new kernels (can be turned off at runtime by setting 'RSB_WANT_RSBPP=0' in the environment). * Added a C++ API (classes RsbMatrix and RsbLib) in new header <rsb.hpp>. * Environment variable 'RSB_NUM_THREADS' now used by default (implicit configure '--enable-rsb-num-threads'). * Fixed integer overflow situations with limit-large matrices. * Improved parallelism of rsb_spmv()/rsb_spmm() a bit (no overly strict locking). * Improved performance of rsb_spmv()/rsb_spmm() beta-scaling. * Tue Nov 02 2021 Jan Engelhardt <jengelh@inai.de> - Update to release 1.2.0.10 * rsb_spmm(...,RSB_FLAG_WANT_ROW_MAJOR_ORDER,...) internals had swapped ldB and ldC so having ldB > ldC could lead to a crash; with ldC < ldB, to wrong results. * rsb_spmm(...,RSB_FLAG_WANT_ROW_MAJOR_ORDER,...) on matrix with RSB_FLAG_UNIT_DIAG_IMPLICIT could have computed wrong results. * rsb_tune_spmm()/rsb_tune_spsm() could have crashed if called with order==RSB_FLAG_WANT_ROW_MAJOR_ORDER and auto leading dimensions and implicit operands (ldB==0 and Bp==NULL, ldC==0 and Cp==NULL). * rsb_mtx_get_rows_sparse() with: was ignoring RSB_TRANSPOSITION_C. * Thu Dec 24 2020 Jan Engelhardt <jengelh@inai.de> - Update to release 1.2.0.9 * Fixed: rsb_mtx_rndr(..RSB_MARF_EPS) and rsb_file_mtx_rndr(..RSB_MARF_EPS): could crash on uniform-values matrix input. * Fixed: rsb_spmsp was crashing if result matrix has nnz<=rows * Fixed: BLAS_zusaxpy and BLAS_cusaxpy in C were crashing * Fixed: rsb_sppsp() was ignoring transB and could crash on transA * Thu Mar 05 2020 Jan Engelhardt <jengelh@inai.de> - Update to release 1.2.0.8 * bugfix: rsb_spmv/rsb_spmm/BLAS_cusmv/BLAS_zusmv/BLAS_cusmm/ BLAS_zusmm could compute wrong values in transpose or conjugated transpose on very sparse complex hermitian matrices. * Thu Jul 12 2018 bwiedemann@suse.com - Add reproducible.patch and set an explicit memory hierarchy to make build reproducible (boo#1100677) * Tue Dec 26 2017 jengelh@inai.de - Update to new upstream release 1.2.0~rc7 * bugfix: rsb_spmv/rsb_spmm/BLAS_cusmv/BLAS_zusmv/BLAS_cusmm/ BLAS_zusmm could compute wrong values on complex hermitian matrices if rhs imaginary part non null. * bugfix: complex conjugated transpose rsb_spsv/rsb_spsm/BLAS_cussv/BLAS_zussv/BLAS_cussm/BLAS_zussm could compute wrong values if rhs imaginary part non null. * bugfix: rsb_sppsp/rsb_mtx_clone would compute scaled conjugate of complex matrices wrong if alpha imaginary part non null. * might detect a forgotten rsb_lib_init() at first matrix allocation and return an error. * Sat Apr 29 2017 jengelh@inai.de - Update to new upstream release 1.2.0~rc6 * BLAS_zusget_element & co will behave one-based in Fortran. * rsb_sppsp was summing incorrectly certain non-overlapping sparse matrices. * rsb_file_mtx_save and rsb_file_vec_save's output use full-precision. - Add pun.diff * Thu Oct 20 2016 jengelh@inai.de - Update to new upstream release 1.2.0~rc5 * Fixed EPS rendering of matrices, e.g. `./rsbench --plot-matrix -aRzd -f matrix.mtx >matrix.eps` - Drop shlib.diff (applied upstream) * Wed Jun 08 2016 jengelh@inai.de - Update to new upstream release 1.2.0~rc3 * Extension: if parameter flagsA of mtx_set_vals() has RSB_FLAG_DUPLICATES_SUM, then values will be summed up into the matrix. * Bugfix: rsb_mtx_get_nrm on symmetric matrices was buggy. * Bugfix: rsb_spsm potentially wrong in --enable-openmp and (nrhs>1). (ussm affected) * Bugfix: rsb_spsm wrong in --disable-openmp version and (nrhs>1). (ussm affected) * Bugfix: rsb_spsm used to scale only first rhs when (*alphap!=1 and nrhs>1). (ussm affected) * Bugfix: rsb_spsm used to solve only first rhs when (y != x). (ussm not affected) * Bugfix: rsb_spmm used to scale only first rhs when (*betap!=1 and nrhs>1). (usmm not affected) * Bugfix: rsb_tune_spmm/rsb_tune_spsm returned (false positive) error on ( mtxAp != NULL && mtxOpp != NULL ) rather than on ( mtxAp != NULL && mtxOpp != NULL && *mtxOpp != NULL ). * Will use memset() on systems with no bzero() (e.g. mingw). * Sun Jan 17 2016 jengelh@inai.de - Initial package (versoin 1.2.0~rc2) for build.opensuse.org
