On the Parallel Performance of SPAI-FETD Solvers for Time-Domain Maxwell's Equations

We evaluate the parallel performance of the Sparse Approximate Inverse (SPAI) based Finite Element Time-Domain (FETD) method to solve time-domain Maxwell's equations. We examine the performance of the parallel computation of the SPAI matrix itself as well as the parallel speedup of the resulting SPAI-FETD simulations in a cluster machine
