- Abstract
Hybrid Red-Black Ordering algorithm can be combined with Jacobi, CG, GMRES (wi). To ac-celerate the convergence rate, an improvement of hybrid Jacobi algorithm with keeping the parallelism is proposed in the paper to instead iterative matrix I--A with D-1 (D--A). The iterative times and running time are decreased. The results of numerical experiments show that the improved algorithm has faster convergence rate.
