Abstract
In this research, a new technique of the particle method is proposed for the reduction of communication between nodes in the PC clusters. Particle numbers are rearranged along one axis using a bucket. This reduces the amount of communication between nodes. The maximum and minimum particle numbers in the communication list are memorized. A simulation of fluid dynamics using 6,300,000 particles was carried out as an example, and it was shown that the efficient parallel calculation was possible in the large-scale analysis.
