Using high performance computing to analyse electrically large planar scattering structures via the method of moments technique-an initial comparison for suitable HPC platforms

Abstract

Analysis of electrically large planar conducting structures is examined, by employing parallel computations of an integral equation technique in conjunction with a method of moments (MoM). The integral equation, in terms of the induced conductivity currents, is solved using entire domain Galerkin technique, with Chebyshev type basis functions. The resulting algorithm parallelisation enables extension of the proposed methodology above the resonance region. Numerical results are computed for several scatterer sizes and excitations source types on varying HPC platforms, namely: CRAY C-90, CRAY T3D, Silicon Graphics Power Challenge and Intel Paragon XP/S. An initial comparison is made between these diverse computing platforms for their applicability/suitability in solving fundamental electromagnetic problems in the domain of electrically large planar scattering structures. Their suitability is not only judged on performance obtained, but also on ease of code portation.
