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’ numerical stability and time-to-solution performance. We also analyze how the use of a preconditioner impacts the choice of the fastest solver. %B Parallel Computing %8 2017-06 %G eng %U http://www.sciencedirect.com/science/article/pii/S0167819117300777 %!
