A Thick-Restart Lanczos algorithm with polynomial filtering for Hermitian eigenvalue problems
Ruipeng Li, Yuanzhe Xi, Eugene Vecharynski +2
Polynomial filtering can provide a highly effective means of computing all eigenvalues of a real symmetric (or complex Hermitian) matrix that are located in a given interval, anywh…

Low-rank correction methods for algebraic domain decomposition preconditioners
Ruipeng Li, Yousef Saad
This paper presents a parallel preconditioning method for distributed sparse linear systems, based on an approximate inverse of the original matrix, that adopts a general framework…

Schur Complement based domain decomposition preconditioners with Low-rank corrections
Ruipeng Li, Yuanzhe Xi, Yousef Saad
This paper introduces a robust preconditioner for general sparse symmetric matrices, that is based on low-rank approximations of the Schur complement in a Domain Decomposition (DD)…
