| 摘 要： | 为了能够使大型机和高性能集群得到更好的加速比和并行计算效率，在深入研究并行和FDTD-PIC算法的基础上，在CHIPIC软件平台上开发了Linux系统下的大型全三维可并行电磁PIC代码。分别以一个磁绝缘线振荡器、回旋管和相对论速调管为例进行测试和计算，得到了3.70,6.72和6.00的加速比，验证了在同等的进程数下，高性能集群能够得到比PC机群高得多的加速比和计算效率，能够更好地利用计算资源。

| 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. |
