We present a parallelizable SSOR preconditioning scheme for Krylov subspace iterative solvers which proves to be efficient in lattice QCD applications involving Wilson fermions. Our preconditioner is based on a locally lexicographic ordering of the lattice points. In actual Hybrid Monte Carlo applic

Gauge invariant expectation values for lattice gauge theory with a general local action in two dimensions may be expressed as functions of the single plaquette averages. The value of these averages at the fixed point of the renormalization group can be determined exactly, and the corresponding latti
We present a representation of SU(3) matrices by 8 real parameters. By truncating each parameter to 8 bits we are able to code each SU(3) link variable in one (64 bit) word of memory which reduces the amount of storage space needed by a factor of at least 6. A ten hit Metropolis program using this s
