摘要：

The parallelization of preconditioned Krylov subspace method is essential for the fast electromagnetic field analysis using edge-based finite element method (FEM). Recently, the parallelization of preconditioned Minimized Residualmethod based on the Three-term Recurrence formula of the CG-type (MRTR) method by means of multicolor (MC) ordering was demonstrated on the real symmetric linear systems arising in edge-based FEM. Then, this paper investigatesthe parallelization performance of preconditioned conjugate orthogonal MRTR (COMRTR) method using MC ordering in complex symmetric linear systems. Furthermore, the affinity of two orderings (Reverse Cuthill-McKeeand greedy-based MC) on complex symmetric linear systems derived from frequency-domain edge-based FEM is particularly verified. © 2015 The Institute of Electrical Engineers of Japan.
