摘要

本文应用基于消息传递(Message Passing)模式的网络并行计算系统来实现并行FDTD方法.通过区域分割技术将FDTD计算区域分割成多个子域进行分别计算

各个子区域在边界处与其相邻的子区域进行切向场值的数据交换以使整个迭代进行下去

从而实现FDTD并行计算.我们采用PVM并行平台来实现并行FDTD算法.计算结果表明了本方法的正确性和有效性.

Abstract

We present a parallel algorithm for the FDTD method on a distributed network by using the message passing module.The computation space is divided into some sub-domains.Then the fields inside each sub-domain are computed on an individual processor with a small amount of data being communicated from neighboring sub-domains.The special boundaries in the FDTD domain

such as absorbing boundaries

connective boundaries and near-to-far fields transform boundaries are dealt with particularly.In this paper

a parallel programming console of Parallel Virtual Machine (PVM) is used

which denotes a message passing library and a daemon to carry out the parallel programs.
