HIGHLY PARALLEL IMPLEMENTATION OF THE 3D INTEGRAL EQUATION ASYMPTOTIC PHASE METHOD FOR ELECTROMAGNETIC SCATTERING

Abstract

In this paper, we discuss the implementation of the 3D Integral Equation-Asymptotic Phase (IE-AP) method using the parallel architecture IBM RS/6000 SP. The IE-AP method is a hybrid numerical/asymptotic approach for electromagnetic scattering that attempts to reduce the number of unknowns required to accurately model electrically large structures. The IE-AP method will be described, and results will be reported for the parallel matrix fill implementation, and the relative performance of the PESSL and PETSc toolkits for parallel matrix solution.
