摘要
In this paper, we proposed various types of synchronous and asynchronous twostage multisplitting iterative methods for the parallel solution of linear algebraic systems. Convergence theories were given and relaxed forms of these methodswere investigated when the coefficient matrix is either monotone or an H-matrix.Computational experiments on CHALLENGE-L were presented.
