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

Cen Ong, M. Weldon, D. Cyca, M. Okoniewski

Abstract

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.
