Multi-GPU accelerated P-FFT method for efficient modeling of antennas mounted on complex and large platform

This paper presents a multi-GPU accelerated fast integral equation solver for efficient modeling of antennas mounted on complex and large platform. The antenna system with surface-wire configuration is characterized using surface wire integral equation (SWIE). The SWIE is solved using the Precorrected-FFT (P-FFT) method on multi-GPUs. Special mapping schemes are proposed to efficiently map the P-FTT algorithm to multi-GPU platform. Very good performance achieved validates the proposed multi-GPU mapping schemes.
