Parallel Electric Field Integral Equation Solver for Arbitrary Shaped Conducting Bodies
Parallel processing using distributed computers becomes important as computationally demanding applications in electromagnetic fields require highly efficient yet cost effective solutions. In this paper, we describe the development of parallel processing strategies of the Method of Moment applicable to a variety of electromagnetic problems such as scattering problems. A linear system of equations for the surface currents induced on a conducting scatterer is derived using the Method of Moment in conjunction with the RWG basis function. The Conjugate Gradient method is used to solve the linear equation. To reduce the total execution time of this procedure, we use distributed computers to process the most time consuming tasks, which are building the Z matrix and finding the surface currents by the Conjugate Gradient method. Our parallelization scheme is tested and run up to 10 distributed computers and the Message Passing Interface (MPI) is used for communicating among the nodes. From our experiment, we achieve more than 8-fold gain using 10 processors for solving the EFIE in parallel and prove the efficiency of our strategy.
