The efficiency of a parallel higher-order method of moments is illustrated using up to 4096 CPU cores on a supercomputer. The scattering problems solved include the analysis from two full scale airplanes and the radiation problems include performance of a microstrip patch phased array antenna mounted on an airplane. Both the scattering and radiation problems are simulated to demonstrate the efficiency of the algorithm implementation. Numerical results show that one can achieve above 60% efficiency when the used memory to the total memory ratio is larger than 15%, and the time can reach a theoretical value between O(N2) and O(N3), where N is the number of unknowns. Due to its high efficiency, the algorithm is able to accurately solve large complex electromagnetic problems including composite and multiscale structures.
