Abstract

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.
