摘要
Abstract
The parallel FDTD computation based on message passing interface (MPI) and domain segmentation technology is achieved in a computer local area network. The parallel FDTD algorithm was validated through the example of the free space radiation of the infinite long current source. The result show that the results of serial and parallel algorithms are consistent,and the computing efficiency is improved effectively. The data communication of parallel algorithm was optimized and the parallel efficiency was improved by the reduction of communication data volume, optimization of data exchange mode, overlap of computation and communication.关键词
