| Résumé | A parallel boundary integral algorithm for solving boundary value problems on distributed memory computer systems is presented. The paper focuses on parallelizations of the influence coefficients matrix generation and the solution of the resulting linear system, which are the two main parts of boundary integral formulations. The matrix of coefficients is large, dense and nonsymmetric. Three parallel linear system solves are presented. It is found that distributed memory parallel algorithms are machine dependent. The paper presents results and discussions on the selection of simple robust algorithms, easily implemented on specific hardware topologies and provides information for extending the selected methods to different parallel machines. The results can serve as a reference for parallel computer benchmarking. |
