Parallel out-of-core higher-order Method of Moments accelerated by Graphics Processing Units

In this paper, the Radar Cross Section (RCS) of an airplane is accurately simulated using Graphics Processing Units (GPU) accelerating parallel out-of-core higher-order Method of Moments (MoM). A GPU-CPU-HDD out-of-core technique is presented to break the restriction of GPU and CPU memory. This can significantly improve the computational capability of the hybrid parallel CPU/GPU implementation of higher-order MoM for large complex electromagnetic problems. Numerical results demonstrate that the parallel GPU-CPU-HDD out-of-core implementation can obtain a good speedup.
