RCS Computation Using a Parallel in-Core and Out-of-Core Direct Solver

Abstract: 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… Show more

“…Clearly, the CC-Edge formulation needs to improve the solving technique (using Lagrange multipliers to stabilize the solution or a better preconditioning [31,32,22] or direct methods [33]) but, of course, at the cost of increasing the computational demands. By contrast, the RM-Nodal formulation is able to solve the problems effectively with a very simple iterative solver (as it is also shown in [2,14,1,16]).…”

“…Previous parallel algorithms (e.g., parallel FDTD [10,11], parallel direct solver [12] and parallel MLFMM [13,14]) were mainly implemented on CPU clusters. Due to the high performance/cost ratio and the fast performance growth of GPUs, GPU clusters are becoming more and more popular.…”

“…High frequency methods can provide fast and robust prediction of radar cross section (RCS) for electrically large targets [1]. Physical optics (PO) can provide reasonable solutions for first-order scattered fields [2], but it cannot consider multiple scattering terms.…”
