Abstract

This paper investigates fast electromagnetic field analysis on parallel computers mutually integrated by means of grid computing technology. To utilize the heterogeneous parallel computation environment, we introduce four parallelized ICCG solvers: the block ICCG, load-balanced block ICCG, algebraic block red-black ordering, and recursive reordering methods. These solvers are evaluated in a finite edge-element eddy-current analysis on integrated parallel computers.
