Implementing parallel elliptic solver on a Beowulf cluster

Marcin Paprzycki, Svetozara Petrova, & Julian Sanchez

Abstract:
In a recent paper [5] a parallel direct solver for the linear systems arising from elliptic partial differential equations has been proposed. The aim of this note is to present the initial evaluation of the performance characteristics of this algorithm on Beowulf-type cluster. In this context the performance of PVM and MPI based implementations is compared.
