Parallel and Vector Performances of GeoFEM and Its Extensions to a Solid Earth Simulator

GeoFEM is parallel FE software challenging for wide range of solid earth problems as well as various practical issues in engineering and sciences. Linear equation solver, one of the key technologies of GeoFEM, has been successfully parallelized and vectorized to make the best use of GS40, which will be available in March, 2002. Also, some solid earth applications have been explored such as stress accumulation on a fault surface, earthquake wave propagation, dynamics of outer core, etc. Recent advances of GeoFEM include extension of framework to other grid systems than FEM, coupler to manipulate interactions among modules and/or grids, enrichment of parallel visualization functions.
