针对国产超级计算机平台上大规模电磁仿真软件相对匮乏,本文将并行高阶矩量法程序移植到国产超级计算机平台上,并以机载线天线阵列的辐射特性计算为例对其并行性能进行了测试和评估。实现了并行高阶矩量法单一任务突破10万CPU核规模,这是目前在国产超级计算机平台上实现的最大规模并行矩量法计算。以1440核为基准,使用CPU核数达到102400,并行规模扩大约70倍时,并行矩量法矩阵方程求解并行效率仍在50%以上。这一研究工作,使利用纯国产超级计算机对复杂电大电磁系统进行精确高效仿真成为可能。
In view of the relative lack of large-scale electromagnetic simulation software on domestic supercomputing platform, the parallel high-order moment method is transplanted to the domestic supercomputing platform. Taking the calculation of the radiation characteristics of on-board antenna array as an example, Test and evaluation. Realization of the parallel high-order method of moment of a single task to break the 100000 CPU core size, which is currently in the domestic supercomputer platform to achieve the largest-scale parallel method of moment calculation. When using 1440 core as a benchmark, the CPU core number reaches 102400 and the parallel scale expands by about 70 times, the parallel efficiency of the matrix method of the moment method is still above 50%. This research makes it possible to use the purely domestic supercomputer to accurately and efficiently simulate a complex electromagnetism system.
