Abstract:

The massively parallel Finite-Difference Time-Domain(FDTD) computation using 100000 CPU cores is firstly implemented. Test results show that the parallel efficiency can reach up to 65% on 10240 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 home-made supercomputer platform.

Key words: parallel algorithms, 100000 CPU cores, finite-difference-time-domain, computational electromagnetics
