| 摘 要： | 为了在刀片服务器平台发挥并行FDTD的最佳性能，以舰船模型上两根超短波天线的远场辐射分析为例，采用各种节点配置和MPI虚拟拓扑结构进行计算，分析了不同MPI虚拟拓扑对并行性能的影响，提出了刀片服务器平台中MPI编程环境的并行FDTD的最佳虚拟拓扑选择原则．以F117飞机模型为例，利用该方法准确快速地计算了其工作于2GHz的雷达散射截面，该问题需很大内存，基于PC集群的并行FDTD无法处理．

| Abstract: | In order to make full use of the performance of the parallel FDTD method based on the blade serve, the radiation patterns in the far field of two ultra short wave antennas mounted on a ship model are calculated. The results are obtained by different cores and various virtual topologies. Then after analyzing the influence of topology schemes on parallel performance of Parallel FDTD on the blade serve, the paper presents the best MPI virtual topology for Parallel FDTD based on the blade serve. Finally the RCS of F117 is calculated at 2GHz. A mount of memory is needed for the problem but the FDTD based on the PC cluster can not be used to solve that. |
