A Class of Communication-avoiding Algorithms for Solving General Dense Linear Systems on CPU/GPU Parallel Machines

Autor: Laura Grigori, Stanimire Tomov, Marc Baboulin, Jack Dongarra, Adrien Rémy, Simplice Donfack

Publikováno v: ICCS

We study several solvers for the solution of general linear systems where the main objective is to reduce the communication overhead due to pivoting. We first describe two existing algorithms for the LU factorization on hybrid CPU/GPU architectures.
