Description
In this paper, we show the optimization method for the seismic simulation code on the Earth Simulator (ES2). We have developed the two algorithms with the data structures that constitute the optimization method. The first algorithm is the optimization of memory access for the stencil computation. The second algorithm is the pipelined non-blocking communication, which enables to overlap the communications with the calculations easily applied for an existing program. This optimization method allows the seismic simulation to achieve approximately 30[%] to the peak performance of ES2.
