Abstract

Our previous researches have shown the extraordinary performance of quarter sweep iteration to speed-up the original method by four times. In this paper, an experimental study is conducted to show the efficiency of the Red-Black Quarter-Sweep iteration by using the Crank-Nicolson (CN) finite difference approximation scheme to obtain numerical solutions of the first order hyperbolic equation. In this paper, the implementation of the Red-Black strategy to Full-Sweep Gauss-Seidel (FGS-RB), Half-Sweep Gauss-Seidel (HGS-RB), and the Quarter-Sweep GaussSeidel (QGS-RB) methods will be discussed. Finally, through numerical results obtained, the QGS-RB iterative method has been shown to be the most superior method compared to FGS-RB and HGS-RB methods. © 2008 IEEE.
