Abstract

In this paper, a GPU accelerated implementation of the matrix assembly phase of the methods of moments is presented. The modelling of PEC structures using the electric field integral equation and the Rao-Wilton-Glisson basis functions introduced in is considered. NVIDIA CUDA is used to do the GPU development and the double precision support offered by the GT200 architecture is used to provide a high level of accuracy. The CUDA implementation of the matrix assembly phase considered is able to attain a speedup of 65 times over the CPU implementation.
