Large-Scale Parallel Method of Moments on CPU/MIC Heterogeneous Clusters

A hybrid message passing interface and open multiprocessing (OpenMP) enabled many integrated core (MIC) coprocessor-accelerated implementation of the large-scale parallel method of moments (MoM) for solving electromagnetic problems is presented. The out-of-MIC memory strategy and asynchronous data transfer scheme are employed to address the problems of accelerating MoM on CPU/MIC computing platform, and a parallel framework is designed to achieve large-scale parallel algorithm on CPU/MIC clusters. The experimental results show that a high parallel efficiency of 45% is achieved when 1024 computing nodes or 80 000 cores are utilized.
