Abstract Asynchronous Many-Task (AMT) runtime systems take advantage of multi-core
architectures with light-weight threads, asynchronous executions, and smart scheduling. In …

This work focuses on the iterative solution of sequences of KKT linear systems arising in
interior point methods applied to large convex quadratic programming problems. This task is …

In this paper, a novel inverse-based multifrontal block incomplete LU preconditioner is
proposed, which is derived from the complete multifrontal method and the inverse-based …

Here, the IRIS programming model is evaluated as a method to improve performance
portability for heterogeneous systems that use LU matrix factorization. LU (lower-upper) …

A new strategy for updating preconditioners by polynomial interpolation of factors of
approximate inverse factorizations is proposed here. The computational cost per iteration is …

In this paper, we introduce a preconditioning strategy for unsymmetric shifted linear systems
(A+ α I) x= b, which is a generalization of the scheme proposed by Bellavia et al.(2011). By …

The paper considers the issue of using iteration methods in solving the sequence of linear
algebraic systems obtained in quasistatic analysis of strip structures with the method of …

Abstract The Residual Smoothing Scheme (RSS) have been introduced in Averbuch et al.(A
fast and accurate multiscale scheme for parabolic equations, unpublished) as a backward …

Many applications in structural mechanics require the numerical solution of sequences of
linear systems typically issued from a finite element discretization of the governing equations …

We propose a procedure for building symmetric positive definite band preconditioners for
large-scale symmetric, possibly indefinite, linear systems, when the coefficient matrix is not …
