Abstract
A massively parallel electromagnetic field solver is developed for simulating large antenna array based on supercomputer using domain decomposition method (DDM) together with an in-house massively parallel computing scheme. The proposed solver is validated by comparing the simulated results with that obtained by commercial software. In particular, its speedup, scalability and efficiency are examined in the simulation of some typical large antenna arrays operating at different frequencies. It is numerically demonstrated that our parallel solver can reach a speedup of 7.149 and strong scalability efficiency of 89.36% on 512 CPU cores of 32 computing nodes. Further, a more challenging model is tested by using 1024 CPU cores of 64 computing nodes.
