| Abstract: | For FDTD simulation of electromagnetic large-scale or complicated problems, there exist two challenges: long running time and large memory requirement. Parallel computing which would reduce the workload of one computer is a useful method to meet the challenges. This paper introduced several optimized approaches and discussed the procedure of high performance parallel FDTD algorithm on a cluster system using MPI (Message Passing Interface) library. Results of a numerical example prove the right and efficiency of the proposed scheme and high parallel efficiency is also achieved. |
