Abstract :
In this paper, using 100000 CPU cores, the parallel Finite Difference Time Domain (FDTD) algorithm based on MPI is firstly applied to analyze the radiation characteristic of a microstrip antenna array on the National Supercomputing Center in Jinan (NSCC-JN) successfully, which is a domestically-made supercomputer. And the parallel performance of the code is tested on it. The results show that the parallel efficiency can reach up to 65% on 10240 CPU cores. According to the analysis, the radiation patterns of the array are obtained, which have a good agreement with the ones from MoM.
