Abstract

GeoFEM is solid earth simulator software, which is under development to be used by STA’s super parallel computer, “Earth Simulator (GS40)”. GeoFEM has already been used to analyze large-scale static linear problems up to 100M (100,000,000) degrees of freedom (DOF) and demonstrated high performance computing ability by parallel processing. Therefore, in the present study, we apply the same data structure and a similar parallelization method to wave propagation problems. We describe the formulation, parallelization procedure and benchmark results of the wave propagation analysis function of GeoFEM. According to the simple benchmark problem, GeoFEM demonstrated more than 98% of the rate of CPU usage performing parallel wave propagation analysis of 100M DOF problem using 1,000 PEs and also shows almost linear scalability on the Hitachi SR2201.
