| Résumé | Panel method, or boundary element method is widely used in marine hydrodynamics computations, especially for lifting flows in which forces are to be obtained for foil or blade sections. For simulation of multiple propellers and foils, a couple of large, dense and asymmetric matrices are to be generated and to be solved a number of times during a numerical iteration process. A parallel BiCGSTAB matrix solver is developed for this engineering application and tested to run under four different MPI software libraries (MPICH, MPI/Pro, WMPI and Compaq Tru64 MPI) and three different operating systems (Windows 2000 Pro, Red Hat Linux 7.2 and TRU64) under a Compaq Proliant Server and Compaq Alpha ES40 Server. Performance of the matrix solver, for this application case, for each configuration is evaluated in terms of computational time, speed, and price performance ratio for three different matrix sizes: 256MB, 1GB and 4GB. |
