国产CPU平台中高阶矩量法10万核并行性能
|
摘要
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。
To solve the deprivation of large-scale electromagnetic simulation software in domestically-made CPU platform,the paper translates the parallel higher-order Mo M program into domestically-made CPU platform and program's parallel performance is tested and evaluated by the calculation of the radiation characteristic of the airborne wire antenna array. The maximum number of CPU cores breaks through 100 k cores,which is the largest scale of parallel Mo M computation in domestically-made CPU platform at present. The results show that the parallel efficiency is higher than 50% when the parallel scale is expanded about 70 times from 1440 CPU cores to 102400 CPU cores. This study makes it possible that make use of the pure domestic super computer to complete the accurate and efficient simulation of complex electrically large electromagnetic system.
