A distributed memory parallel randomized Kaczmarz for sparse system of equations Bölükbaşı, Ercan Selçuk; TORUN, FAHREDDİN ŞÜKRÜ; Manguoğlu, Murat (2024-01-01) Kaczmarz algorithm is an iterative projection method for solving system of linear equations that arise in science and engineering problems in various application domains. In addition to classical Kaczmarz, there are random...
ENHANCING BLOCK CIMMINO FOR SPARSE LINEAR SYSTEMS WITH DENSE COLUMNS VIA SCHUR COMPLEMENT TORUN, FAHREDDİN ŞÜKRÜ; Manguoğlu, Murat; Aykanat, Cevdet (2023-01-01) The block Cimmino is a parallel hybrid row-block projection iterative method successfully used for solving general sparse linear systems. However, the convergence of the method degrades when angles between subspaces spanne...
Partitioning and Reordering for Spike-Based Distributed-Memory Parallel Gauss--Seidel Torun, Tugba; Torun, F. Sukru; Manguoğlu, Murat; Aykanat, Cevdet (2022-04-01) Gauss--Seidel (GS) is a widely used iterative method for solving sparse linear sys-tems of equations and also known to be effective as a smoother in algebraic multigrid methods.Parallelization of GS is a...
A two-level iterative scheme for general sparse linear systems based on approximate skew-symmetrizers Mehrmann, Volker; Manguoğlu, Murat (2021-01-01) We propose a two-level iterative scheme for solving general sparse linear systems. The proposed scheme consists of a sparse preconditioner that increases the norm of the skew-symmetric part relative to the rest and makes t...
A parallel multithreaded sparse triangular linear system solver Cugu, Ilke; Manguoğlu, Murat (Elsevier BV, 2020-07-15) We propose a parallel sparse triangular linear system solver based on the Spike algorithm. Sparse triangular systems are required to be solved in many applications. Often, they are a bottleneck due to their inherently sequ...

A parallel bio-inspried shortest path algorithm arslan, hilal; Manguoğlu, Murat (Springer Science and Business Media LLC, 2019-08-01) Physarum polycephalum is an amoeba-like organism and is able to find the shortest path in a labyrinth. Inspired by P. polycephalum, recently, a mathematical model and an algorithm (Physarum Solver) was developed. There are...
