In this article, the parallel performance test of JEMS-FDTD on MPP(Massively Parallel Processor) is introduced, including the performance of different patch size, single-node and multi-node MPI/OPENMP hybrid parallel performance, and large scale parallel performance. The test shows that JEMS-FDTD is capable of performing parallel computation on tens of thousands processor cores efficiently. The computation and analyzing of a computer case with complex structure illuminated by pulsed electromagnetic wave is introduced an example, which demonstrates JEMS-FDTD's capability of solving electric-large-scale electromagnetic propagation, radiation, coupling problems on MPP with high efficiency.%介绍了JEMS-FDTD在大规模并行计算机上进行的并行性能测试,包括网格片大小对性能的影响、单节点MPI/OPENMP混合并行性能、多节点MPI/OPENMP混合并行性能、大规模并行性能等.同时,也给出了一个包含电大尺寸复杂、真实结构模型的算例,并对其进行了计算、分析.测试表明,JEMS-FDTD可高效使用数万个处理器核进行并行计算.大型算例测试表明:JEMS-FDTD可针对电大尺寸复杂、真实结构模型进行有效的计算、分析.
