A hybrid recursive multilevel incomplete factorization preconditioner for solving general linear systems
Yiming Bu, Bruno Carpentieri, Zhaoli Shen +1
In this paper we introduce an algebraic recursive multilevel incomplete factorization preconditioner, based on a distributed Schur complement formulation, for solving general linea…
Using the VBARMS method in parallel computing
Bruno Carpentieri, Jia Liao, Masha Sosonkina +1
The paper describes an improved parallel MPI-based implementation of VBARMS, a variable block variant of the pARMS preconditioner proposed by Li,~Saad and Sosonkina [NLAA, 2003] fo…
Restarted Hessenberg method for solving shifted nonsymmetric linear systems
Xian-Ming Gu, Ting-Zhu Huang, Guojian Yin +3
It is known that the restarted full orthogonalization method (FOM) outperforms the restarted generalized minimum residual (GMRES) method in several circumstances for solving shifte…
