Studies on the Efficiency of Massively Parallel Computational Method for Large-Scale Computation based on Unstructured Grid

Katsuya Saitoh, Kazuo Kashiyama

Abstract

Massively parallel finite element method based on unstructured grid for unsteady large-scale computation is presented. The shallow water equation is used for the basic equation. Parallel implementation is performed on the Fujitsu AP1000 and Connection Mechine CM-5. The efficiency of the parallelization techniques is investigated. The present method is shown to be a useful and powerful tool for large-scale computations.
