Abstract :
A fast moment method solution of composite body problems is presented based on a combination of a modified Adaptive Cross Approximation (ACA) algorithm for matrix fill and LU decomposition. The ACA LU algorithm is optionally accelerated by multiple GPUs and comparisons are presented for various problems simulated on Intel Xeon processors and NVIDIA GPU cards.
