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 airflow over complex terrain with high precision. Since we put this numerical model in practical use, we are considering introduction of a PC cluster and a SMP cluster. We have already showed the comparison of the elapsed time in various computers as the first step. In this paper, we have examined the elapsed time in scalar parallel computers, such as a PC cluster and a SMP cluster, by using a MPI (Message Passing Interface), as the second step. Consequently, it became clear that the newest small scalar parallel computers have about the same performance as a vector supercomputer.show more
