Symmetry and BEM on transputers J.Lobry Department of Electrical Engineering, Faculte Polytechnique de Mons, Bd. Dolez, 31, 7000 Mons, Belgium ABSTRACT Geometrical and material symmetries are found in many linear field problems. They can be taken into account thanks to a rationale called the Group Representation Theory. This method consists in reducing an original problem into a family of smaller ones, the overall solution is the sum of the sub- problems. In this paper, we propose the implementation of the Boundary Element Method on distributed memory computers for two-dimensional problems in this context. Different parallel strategies are analysed and compared. Experimental results are obtained on a Meiko Computing Surface with 16 T800 transputers. INTRODUCTION After recent experiences of Bryant et al. [1], Daoudi and Lobry [2,3] in the parallelization of the Boundary Element Method (BEM) on distributed memory computers, we investigate in problems that
