Abstract

This paper describes a proposal for a set of Parallel Basic Linear Algebra Subprograms (PBLAS) for distributed memory MIMD computers. The PBLAS are targeted at distributed vector-vector, matrixvector and matrix-matrix operations with the aim of simplifying the parallelization of linear algebra codes, especially when implemented on top of the sequential BLAS.
