Very large scale calculations by Ground Motion Simulator

Abstract Large-scale wave propagation simulations using FDM requires huge computation resources. To overcome this difficulty, we developed, by using CUDA, the multi GPU version of GMS (Ground Motion Simulator) which is a total system for seismic wave propagation simulation based on 3-D FDM using discontinuous grids. We also develop and evaluate the performance the code for K computer which is the Japanese fastest supercomputer operated by RIKEN.
