Fast Krylov Space Methods for Calculation of Quark Propogator
arXiv:hep-lat/9405001
Abstract
Different recently developed Krylov space methods for solving linear systems are studied and compared for the solution of the Dirac equation on the lattice. Stabilized Biconjugate Gradient (BiCGstab2) is shown to be a robust and efficient solver for the calculation of the Wilson quark propagator in lattice QCD.
