A Preconditioner for Improved Fermion Actions
نویسندگان
چکیده
SSOR preconditioning of fermion matrix inversions which is parallelized using a locally-lexicographic lattice sub-division has been shown to be very efficient for standard Wilson fermions. We demonstrate here the power of this method for the Sheikholeslami-Wohlert improved fermion action and for a renormalization group improved action incorporating couplings of the lattice fermion fields up to the diagonal in the unit hypercube.

Preconditioning of Improved and “Perfect” Fermion Actions
We construct a locally-lexicographic SSOR preconditioner to accelerate the parallel iterative solution of linear systems of equations for two improved discretizations of lattice fermions: (i) the Sheikholeslami-Wohlert scheme where a non-constant blockdiagonal term is added to the Wilson fermion matrix and (ii) renormalization group improved actions which incorporate couplings beyond nearest ne...

We generalize l ocal l exicographic SSOR preconditioning for the Sheikholeslami-Wohlert improved Wilson fermion action and the truncated perfect free fermion action. In our test implementation we achieve performance gains as known from SSOR preconditioning of the standard Wilson fermion action.
متن کاملSSOR Preconditioning of Improved Actions
The standard Wilson fermion action of lattice QCD leads to discretization-errors of O(a) in lattice spacing, requiring prohibitively ne lattice resolutions in the approach to the chiral and continuum limits [1]. The present trend to tackle this problem goes in two directions: (i) One approach is based on Symanzik's on-shell improvement program, where irrelevant O(a) counter terms are added to b...
متن کاملTests of Hypercubic Fermion Actions
I have performed scaling tests using quenched spectroscopy of a family of fermion actions which have a hypercubic kinetic term, gauge connections built of smeared links, and an anomalous magnetic moment term. These actions show improved rotational invariance compared to the standard Wilson action and to the tadpole-improved clover action. Hyperfine splittings are improved compared to the standa...
متن کاملSpeeding up the HMC algorithm: Some new results
We give some new performance results for the Hybrid Monte Carlo (HMC) simulation of dynamical clover-improved Wilson fermions using an improved pseudo-fermion action. The generalisation of even-odd preconditioning for the standard Wilson fermion matrix to the clover-improved case is not unique. In the literature the so called symmetric and asymmetric versions are discussed. Most of the previous...
