Novel source-to-source compiler approach for the automatic parallelization of codes based on the method of moments

In computational electromagnetics, surface integral equation (SIE) formulations are widely used to predict the electromagnetic scattering from arbitrary structures. These SIE formulations are discretized into a matrix form by the well-known method of moments (MoM). Up to now, the lack of proper compilers made it necessary for the MoM codes to be parallelized by hand in order to obtain reasonable performance on present computers. Since MoM codes are very complex, this manual parallelization is always a tedious error-prone task. In this paper we present a new parallelizing compiler, called Parallware, based on a novel disruptive technology for the automatic parallelization of sequential codes written in the C programming language. We show through simulation performance results that, starting from real sequential MoM codes for penetrable scatterers, this new compiler provides efficient parallel MoM codes automatically.
