BlockSolve95 users manual: Scalable library software for the parallel solution of sparse linear systems

BlockSolve95 is a software library for solving large, sparse systems of linear equations on massively parallel computers or networks of workstations. The matrices must be symmetric in structure; however, the matrix nonzero values may be either symmetric or nonsymmetric. The nonzeros must be real valued. BlockSolve95 uses a message-passing paradigm and achieves portability through the use of the MPI message-passing standard. Emphasis has been placed on achieving both good professor performance through the use of higher-level BLAS and scalability through the use of advanced algorithms. This report gives detailed instructions on the use of BlockSolve95 and descriptions of a number of program examples that can be used as templates for application programs
