Recently, Tian et al. [Computers and Mathematics with Applications, 75(2018): 2710-2722] came up with the inner-outer iterative method to solve the linear equation Ax=b and studied the corresponding convergence of the method. In this paper, we improv

Based on the methods presented by Song and Yuan (1994), we construct relaxed matrix parallel multisplitting chaotic generalized USAOR-style methods by introducing more relaxed parameters and analyze the convergence of our methods when coefficient mat

The convergence theory for the restricted version of the overlapping Schur complement preconditioner
Publikováno v:
Applied Mathematics and Computation. 339:422-430
The restricted version of the overlapping Schur complement (SchurRAS) preconditioner was introduced by Li and Saad (2006) for the solution of linear system A x = b , and numerical results have shown that the SchurRAS method outperforms the restricted

In this paper, based on the current mainstream multi-core architecture of parallel computer and the robust structured multifrontal factorization (in brief, RSMF) method, we propose a multi-core parallelization of RSMF (in brief, MRSMF) method. MRSMF

Preconditioning technique has been used for transforming the original linear system into one which has the same solution, but likely easier to solve with an iterative solver. Using lower precision computation is a method to accelerate precondition pr
