Abstract

In this paper, the Graphics Processing Unit (GPU) computing and the Cluster of Workstations (COW) techniques have been discussed and introduced into computational electromagnetics. Based on the two hardware acceleration techniques, a high efficiency Finite-Difference Time-Domain (FDTD) algorithm has been developed and implemented in two nodes COW system with a GPU in each node. Three typical EM simulation examples have been executed following the proposed scheme, the simulation results show good agreement between the GPU+COW scheme and the traditional CPU computing while at least 60 times speedup has been achieved.
