A two-level iterative scheme for general sparse linear systems based on approximate skew-symmetrizers
Murat Manguoglu, Volker Mehrmann
We propose a two-level iterative scheme for solving general sparse linear systems. The proposed scheme consists of a sparse preconditioner that increases the skew-symmetric part an…
A Robust Iterative Scheme for Symmetric Indefinite Systems
Murat Manguoglu, Volker Mehrmann
We propose a two-level nested preconditioned iterative scheme for solving sparse linear systems of equations in which the coefficient matrix is symmetric and indefinite with relati…
A Novel Partitioning Method for Accelerating the Block Cimmino Algorithm
F. Sukru Torun, Murat Manguoglu, Cevdet Aykanat
We propose a novel block-row partitioning method in order to improve the convergence rate of the block Cimmino algorithm for solving general sparse linear systems of equations. The…
Adaptive discontinuous Galerkin methods for non-linear diffusion-convection-reaction equations
Murat Uzunca, Bülent Karasözen, Murat Manguoğlu
In this work, we apply the adaptive discontinuous Galerkin (DGAFEM) method to the convection dominated non-linear, quasi-stationary diffusion-convection-reaction equations. We prop…
A domain decomposing parallel sparse linear system solver
Murat Manguoglu
The solution of large sparse linear systems is often the most time-consuming part of many science and engineering applications. Computational fluid dynamics, circuit simulation, po…
