It is of interest to determine whether loosely coupled multiprocessors can be profitably used for the solution of larger numerical problems. The authors present a performance evaluation of the gain obtained by solving partial differential equation systems on such an architecture. The experimental setting is an LSI 11 based multiprocessor system using a fiber optics local area network designed and implemented at Laboratoire de Recherche en Informatique, Universite Paris-Sud. The paper includes a discussion of the numerical methods and of their implementation, a performance model of the parallel processing system, and measurements taken on the experimental system. The experimentally validated theoretical results confirm the interest of the authors approach based on performance models. 11 references.
