“…Both of these must be handled efficiently. Furthermore, efficient parallel matrix filling for MoM with HOBs introduces new challenges and is quite different from the procedure used in a MoM formulation using the traditional subdomain basis functions, e.g., RWGs [5].…”

“…However, the matrix filling scheme will be most efficient if the characteristics of the basis functions are taken into account. An efficient matrix filling scheme for a MoM using RWGs was presented in [5]. Different steps than described in [5] need to be taken to deal with HOBs.…”

“…The constant development of the computer technology sets objectives more and more ambitious for the electromagnetic solvers, as described by Taboada et al in [1]. Parallel technology has been used in various CEM methods, such as the Method of Moments (MoM) [2][3][4][5], Fast Multipole Method (FMM) [1,6,7], Finite Element Method (FEM) [8] and FiniteDifference Time-Domain method (FDTD) [9][10].…”

Abstract-A Message Passing Interface (MPI) parallel implementation of a hybrid solver that combines the Method of Moments (MoM) with higher order basis functions and Physical Optics (PO) has been successfully used to solve a challenging problem including a 2160-slot waveguide array on an airplane with a maximum dimension larger than 1000 wavelengths. The block-partitioned scheme for the large dense MoM matrix combined with the process-cyclic scheme for the PO discretized triangles is designed to achieve excellent load balance and high parallel efficiency. To break the limitation of physical memory, the parallel out-of-core technique is introduced to tackle large dense systems generated using the MoM formulation. This research provides a solution with reasonable accuracy for solving large on-board antenna problems but has very low memory usage.

“…A different approach is to rely on techniques on the computer science side and to implement a pure MoM without any approximation/acceleration technique. In this context, the objective of the paper is to evaluate the performance of a parallel electromagnetic direct solver for RCS computation which has been developed by the authors in the last years [40][41][42][43]. Specifically, two different techniques are implemented: parallel processing [44] and out-of-core algorithms, i.e., use of hard-disk memory in addition to RAM memory.…”

Abstract-Application to RCS computation of a higher order solver based on the surface integral approach is presented. The solver uses a direct method to solve the corresponding algebraic system of equations. Two versions of the solver are available: in-core and out-of-core. Both are efficiently implemented as parallel codes using Message Passing Interface libraries. Several benchmark structures are analyzed showing the reliability, performance, and versatility to run in a wide variety of computer platforms, of the solver. The results shown are illustrative of what is the maximum frequency of analysis of the structures for a given type of simulation platform.
