We consider the BiCGSTAB, CGS, QMR, and IDR(s) Krylov solvers. For a large set of test matrices, we assess the impact of Jacobi and incomplete factorization preconditioning on the solvers{\textquoteright} numerical stability and time-to-solution performance. We also analyze how the use of a preconditioner impacts the choice of the fastest solver.}, keywords = {gpu, ILU, Jacobi, Krylov solvers, Preconditioning}, issn = {01678191}, doi = {10.1016/j.parco.2017.05.006}, url = {http://www.sciencedirect.com/science/article/pii/S0167819117300777}, author = {Hartwig Anzt and Mark Gates and Jack Dongarra and Moritz Kreutzer and Gerhard Wellein and Martin Kohler} }
