MSP: A Class of Parallel Multistep Successive Sparse Approximate Inverse Preconditioning Strategies
TL;DR: A class of parallel multistep successive preconditionsing strategies to enhance efficiency and robustness of standard sparse approximate inverse preconditioning techniques are developed.
Journal ArticleDOI
Global and localized parallel preconditioning techniques for large scale solid Earth simulations
TL;DR: This work investigates and compares a few parallel preconditioning techniques in the iterative solution of large sparse linear systems arising from solid Earth simulation with and without using contact information in the domain partitioning process.
Journal ArticleDOI
Distributed block independent set algorithms and parallel multilevel ILU preconditioners
Chi Shen,Jun Zhang,Kai Wang +2 more
TL;DR: Numerical experiments indicate that the domain-based parallel multilevel block ILU preconditioners are robust and efficient.
Proceedings ArticleDOI
Parallel multilevel block ILU preconditioning techniques for large sparse linear systems
Chi Shen,Jun Zhang,Kai Wang +2 more
TL;DR: In this article, a class of parallel preconditioning strategies built on a multilevel block incomplete LU (ILU)factorization technique to solve large sparse linear systems on distributed memory parallel computers is presented.
Journal ArticleDOI
A Comparative Study on Dynamic and Static Sparsity Patterns in Parallel Sparse Approximate Inverse Preconditioning
Kai Wang,Sangbae Kim,Jun Zhang +2 more
TL;DR: This work conducts a comparable study on the properties and performance of the SAI preconditioners using the different sparsity patterns for solving some sparse linear systems.
