Improving Inversions of the Overlap Operator

High Energy Physics - Lattice 2009-11-10 v1

Abstract

We present relaxation and preconditioning techniques which accelerate the inversion of the overlap operator by a factor of four on small lattices, with larger gains as the lattice size increases. These improvements can be used in both propagator calculations and dynamical simulations.
