• With the introduction of GPU, a new revolution has been opened in high performance computing. For accurate early warning for Tsunami disasters, the shallow water equation has to be solved in real-time. Even single GPU enables 62-times faster calculation than 1 CPU core and the same domain decomposition is available for multi-GPU computing, where the communications between GPUs are hidden by overlapping with the computation. For the very large-size domain of 4096x8192 mesh with 90m resolution, the GPU Tsunami simulation finishes within 3 minutes in the case of 8 GPUs. Excellent scalability has been achieved on TSUBAME GPU cluster.
