摘要: 为了更好地实现对大尺度器件的模拟，以及更系统地验证和解决高功率微波系统在设计和实验中负载变化等影响，在进一步深入研究电磁PIC并行算法的基础上，运用MPI消息传递函数做出了改进。提出了一种整体建模、分段解析的并行算法，并从并行时序算法入手，通过减少一次同步提高了计算的效率。最后经过一个磁绝缘线振荡器进行验证，改进的算法正确，并且当计算进程数4个增加到16个时，计算速度能提高2.5倍左右。Abstract: In order to realize simulation of the large scale device, validate and solve the influence of load in the design and experiment of high power microwave system, the electromagnetic PIC parallel algorithm has been improved using MPI message passing function. This paper puts forward a whole modeling, section analytic parallel algorithm, and increase the calculation efficiency by reducing a synchronous. Finally the improved algorithm has been verified using a magnetic insulated line oscillator, and when calculating process number from 4 to 16, the computing speed can improve about 2.5 times.
