Query: Simulation of dynamical fermions with smeared links   Smearing the gauge links of dynamical configurations removes small scale
unphysical vacuum fluctuations und thus improves the chiral properties of
lattice fermions. We present a new algorithm for the simulation of dynamical
fermions coupled via smeared links based on the standard pure gauge
overrelaxation and heatbath updatings. Smeared links play a fundamental role in
making this algorithm effective. At fixed lattice spacing the computational
cost of the algorithm has an extra volume factor due to the finite volume of
the lattice region which can be updated. As the continuum limit is approached
the physical volume of the updated region remains constant. We simulated four
flavors of staggered fermions coupled via hypercubic (HYP) smeared links. The
simulation cost of the new algorithm on 10 fm^4 volumes is a factor 2-8 larger
than with the standard Hybrid Monte Carlo but the improved properties of the
HYP action allow to gain a factor 2 in the lattice spacing. The new algorithm
could be applicable to simulations of more complicated chiral fermionic
actions, like overlap or perfect actions.
