Abstract

This paper presents the parallel implementation of a boundary element code for the solution of 2D elastostatic problems using linear elements. The original code is described in detail in a reference text in the area [Boundary elements techniques: theory and applications in engineering, 1984]. The Fortran code is reviewed and rewritten to run on shared and distributed memory systems using standard and portable libraries: OpenMP, LAPACK and ScaLAPACK. The implementation process provides guidelines to develop parallel applications of the Boundary Element Method, applicable to many science and engineering problems. Numerical experiments on a SGI Origin 2000 shows the effectiveness of the proposed approach.
