NIST Sparse BLAS

Abstract

The NIST Sparse BLAS (Basic Linear Algebra Subprogram) library provides computational kernels for fundamental sparse matrix operations, including sparse matrix products and solution of triangular systems. The current version supports compressed-row, compressed-column, and coordinate sparse storage formats, together with block and variable-block versions of these. Symmetric and skew-symmetric versions are also supported. The routines are written in ANSI C and are callable from Fortran and C. This project is part of the ongoing standardization effort of the BLAS Technical Forum.
