Iterative local solvers for distributed Krylov-Schwarz method applied to convection-diffusion problems. (English) Zbl 0923.76101

Summary: Nowadays, supercomputers can be used to solve large-scale problems that come from simulation of industrial or research problems. However, those machines are usually inacessible to most industries and university laboratories around the world. In this work we present an iterative solver, a Krylov-Schwarz method (KSM), to be used in a collection of workstations under PVM. The subdomain problems are solved by using many methods in order to show how the choice of the local solvers affects the overall performance of the distributed KSM.
