EM Scattering at Rough Surface by Using Parallel FDTD Algorithm

This paper introduced a strategy for parallel implementation of the FDTD algorithm used in COW（Cluster of Workstation）parallel computing system and MPI parallel environment.By using region division,load balance and message passing with two neighboring sub-domains.The theoretic analysis and parallel computing results show that： It is feasible to this parallel FDTD algorithm.When analysising of large-scale electromagnetic scattering problem at rough surface,it could obtain a better speedup rate computing efficiency
