Acceleration of large-scale FDTD simulations on high performance GPU clusters

In this paper,a scalable graphics processing unit (GPU) cluster solution for the acceleration of FDTD for large-scale simulations is proposed. The hardware and software implementations are described. To illustrate the speed performance of the cluster, the simulation results of a cubic resonator with PEC boundaries is presented. A realistic large-scale simulation performed using SEMCAD X from SPEAG, accelerated by Acceleware's software libraries and GPU cluster solution is also presented.
