Abstract
In this paper a parallel organization of a finite volume algorithm for calculation of two-dimensional compressible, viscous gas flows is presented. The problem is addressed to the new emerging area of the micro gas flows, taking place in Micro-Electro-Mechanical Systems (MEMS). Technically, the parallel algorithm is organized by using standard MPI, non-blocking communications and the latency of the communications is overlapped with useful work. The speedup was estimated on two clusters. The first cluster uses MYRINET interconnections (BG04-ACAD). The second uses conventional cards for interconnections (BG03-NGCC). Both clusters are a part of GRID-infrastructure of the European Research Area (ERA). An ideal speedup is obtained on BG04-ACAD for a number of processors up to 20 CPUs. The speedup obtained on BG03-NGCC is very good, however it depends on the mesh refinement.
