Abstract

Abstract

For better computing efficiency in high-performance clusters, a three-dimensional electromagnetic PIC parallel code was developed in Linux system based on the CHIPIC software code. By testing a magnetically insulated transmission line oscillator, gyrotron and relativistic klystron, speedups of 3.70, 6.72, 6.00 are obtained for them respectively. Results show that the high-performance clusters have much higher speedups and computing efficiency than the PC clusters with the same processes, so high-performance clusters could make better use of computing resources.
