Improving the Partial-Global Stochastic Metropolis Update for Dynamical Smeared Link Fermions

Abstract

We discuss several methods that improve the partial-global stochastic Metropolis (PGSM) algorithm for smeared link staggered fermions. We present autocorrelation time measurements and argue that this update is feasible even on reasonably large lattices.
