摘要 结合国产超级计算机研制中软件能力不足的现状,研究了超大规模并行时域有限差分法,实现了10万核的并行时域有限差分法计算.以128CPU核为基准,在10 240CPU核时,该算法的并行效率可以达到65%以上.该文的研究结果表明,并行时域有限差分法可准确有效地在国产超级计算平台上解决复杂超电大电磁工程问题. The massively parallel Finite-Difference Time-Domain(FDTD)computation using 100 000 CPU cores is firstly implemented.Test results show that the parallel efficiency can reach up to 65% on 10 240 CPU cores with 128 CPU cores as the benchmark.The research results in this paper indicate that the complicated electromagnetic problems can be solved accurately and efficiently using the method on the homemade supercomputer platform.
