Parallelization, vectorization and visualization of large scale plasma particle simulations and its application to studies of intense laser interactions

Abstract

The use of a three-dimensional PIC (Particle-in-Cell) simulation is dispensable in the studies of nonlinear plasma physics, such as ultra-intense laser interactions with plasmas. The threedimensional simulation requires a large number of particles more than 107 particles. It is therefore very important to develop a parallelization and vectorization scheme of the PIC code and a visualization method of huge simulation data. In this paper we present a new parallelization scheme suitable for a present day supercomputer and a construction method of scientific color animations to analyze simulation data. We also discuss the advantage of the Abe-Nishihara vectorization method for a large scale PIC simulations.
