Abstract
At recently, the particle method is proposed as one method of analyzing the fluid behavior with Lagrangean approach. This method has the feature to be able to facilitate treatment of the free surface problem comparatively. By using this method, the computation of the large scale simulation becomes indispensable when applying to the problem of the impact to environmental by natural phenomena and the problem of the predict in advance for disaster etc.. In this study, the distributed parallel system was constructed by using SMAC-SPH method which is one of the particle method, and it consider the parallel efficiency.
