Abstract
We generalize local lexicographic SSOR preconditioning for the Sheikho leslami-Wohlert improved Wilson fermion action and the perfect free fe rmion action, with couplings in a unit hypercube. In our test implemen tation we achieve performance gains as known from SSOR preconditioning of the standard Wilson fermion action.
