Abstract

We are developing the numerical model called the RIAM-COMPACT (Research Institute for Applied Mechanics, Kyushu University, Computational Prediction of Airflow over Complex Terrain). The object domain of this numerical model is from several m to several km, and can predict the flow of the wind over complex terrain with high precision. Since we put this numerical model in practical use, we are considering introduction of a PC cluster. This research shows comparison of the CPU time in various computers as the first phase. Consequently, it became clear that the newest computer environment has about the same performance as a supercomputer. The difference in a compiler option is also discussed
