Abstract

A parallel processor system and its mode of operation are described. A notation for writing programs on it is introduced. Methods for iterative solution of a set of linear equations are then discussed. The well-known algorithms of Jacobi and Gauss-Seidel are parallelized despite the apparent inherent sequentiality of the latter. New, parallel methods for the iterative solution of linear equations are introduced and their convergence is discussed. A measure of speedup is computed for all methods. It shows that in most cases the algorithms developed in the paper may be efficiently executed on a parallel processor system.
