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.
