Large-scale Parallel Wave Propagation Analysis (Explicit dynamic analysis using non-reflecting boundary)
Kazuteru Garatani, Hideki Matsumoto


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 and wave propagation problems up to 10$^8$ degrees of freedom (DOF) and demonstrated high performance computing ability by parallel processing.In the present study, we focus on the wave propagation analysis of GeoFEM.The report reviews formulation and parallel benchmark result briefly, then describes installations of viscous boundary and real-time visualization system (RVSLIB) to realize more efficient simulation.According to these extensions, we can apply GeoFEM to more realistic seismic problem.
