Improving Inversions of the Overlap Operator
arXiv:hep-lat/0409030 · doi:10.1016/j.nuclphysbps.2004.11.149
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.
