摘要
提出了在由微机互连构成的机群(COW)并行计算系统上应用基于消息传递(M essage Passing)的方式实现二维FDTD并行算法。通过区域分割,各个子区域在边界处与其相邻的子区域进行场值的数据传递,从而实现FDTD并行计算。文中还仔细分析了与FDTD相关的外围边界的并行化处理。文中以二维金属方柱算例验证了算法的正确性和有效性,并将本文实现的加速比以及并行效率与其它文献进行了比较,从而为运用FDTD方法进行电大尺寸复杂电磁问题数值模拟计算提供了一条有效途径。
This paper introduces a strategy for parallel implementation of the 2-D FDTD algorithm based on COW （Cluster of Workstation） parallel computing system and MPI parallel environment. An analysis of parallelizing the auxiliary tools, such as absorbing boundary and far-field computation, etc, is also presented. A computed example is given to prove the feasibility and correctness of this method. The sealability and efficiency are also compared with other article. This method provides a solve-scheme for the EM computation of electrically-large-size complex object.
