Resumo


The work introduces the main steps towards the parallelization of existing boundary element method (BEM) codes using available standard and portable libraries for writing parallel programs, such as LAPACK and ScaLAPACK. Here, a well-known BEM Fortran implementation is reviewed and rewritten to run on shared and distributed memory systems. This effort is the initial step to develop a new generation of parallel BEM codes to be used in many important engineering problems. Numerical experiments on a SGI Origin 2000 show the effectiveness of the proposed approach.
