摘　　要：工业应用,特别是军事应用对计算电磁学(CEM)的需求提出挑战,解决电大尺寸电磁散射问题(物理尺寸λ1)的有效方法是采用并行计算技术.给出了MLFMA算法基于Linux集群技术的并行实现,并给出了电大尺寸目标电磁散射的计算实例.由于这种并行化方法只是充分利用已有的工作站,编程容易,所以是一种值得推广的并行化实现方法.The demand for computing in computational electromagnetics (CEM) is continuously increasing in industry, especial in military application. Given in this paper are the results that were obtained using the parallel electric field simulation program MLFMA(multilevel fast multi-pole algorithm) on the Linux cluster of PCs connected via an 1000-based Ethernet network interface for large-scale scattering problems. Due to the high performance of the CPUs and interconnection technology, the results obtained on clusters of PCs can be compared to those obtained on expensive multiprocessor machines. A practical EM scattering engineering problem has been calculated.
