摘要

我们研究了有限差分时域(FDTD)算法在并行工作站的Beowulf集群上的Linux实现。我们讨论同步和域分解的备选方案。为了获得性能特征，将该算法应用于一个测试散射问题。采用不同数量的相同双处理器AMD Athlon MP- 1800工作站进行计算，并采用消息传递接口(Message Passing Interface, MPI)处理处理器间通信和并行运行。

Innovative approaches to parallelizing finite-difference time-domain computations

We investigate the Linux implementation of the finite-difference time- domain (FDTD) algorithm on a Beowulf cluster of parallel workstations. We discuss synchronization and domain decomposition alternatives. To obtain performance characteristics the algorithm is applied to a test scattering problem. The computation has been done using varying numbers of identical dual-processor AMD Athlon MP- 1800 workstations with the Message Passing Interface (MPI) used to handle the inter- processor communications and the parallel runtime.
