Parallel performance of multisplitting methods with preweighting (English)
0 references
This paper first gives out a study on the convergence of a special type of multisplitting methods with preweighting for solving linear system. Then it introduces a parallel implementation of the successive overrelaxation (SOR)-like multisplitting method with preweighting and applies it to a parallel preconditioner of Krylov subspace method. At last, it provides the parallel performance results of both the SOR-like multisplitting method with preweighting and Krylov subspace method with the parallel preconditioner. The numerical results show that parallel performance of the method is quite efficient and its application to parallel preconditioner of Krylov subspace method is quite successful.
