Performance Analysis and Optimization of MoM Based on Super Computer System

According to the insatiable requirement for storage and CPU time in analysis of electromagnetic characteristics of complex objects, a high order MoM with high performance and accuracy based on developing domestic super computer system is studied. The redundant computation in parallel filling step of higher order MoM is analyzed, and an algorithm named "element pre-selection" is achieved to eliminate the invalid computation thus to accelerate the filling step. The parallel implementation of LU decomposition algorithm for matrix equations is discussed in detail, and a novel parallel LU decomposition algorithm that requires less communication overhead compared with the original one is proposed. Numerical tests show that the proposed algorithm achieves a high parallel performance on the super computer platform,which greatly improves the simulation ability of the method of moments.
