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.

Key words: finite difference method, parallel algorithms, electrically large platforms, scattering, message passing interface(MPI)
