Abstract
Nowadays, supercomputers can be used to solve large-scale problems tha t come from simulation of industrial or research problems. However, th ose machines ale usually inacessible to most industries and university laboratories around the world. In this work we present an iterative s olver, a Krylov-Schwarz Method (KSM), to be used in a collection of wo rkstations under PVM. The subdomain problems are solved by using many methods in order to show how the choice of the local solvers affects t he overall performance of the distributed KSM.
