Simulations

of QCD with two flavours of improved Wilson quarks on an anisotropic lattice are discussed. Methods for improving the performance of the Hybrid Monte Carlo (HMC) algorithm in these studies are described.

We report on our study of two-flavor full QCD on anisotropic lattices using O(u)-improved Wilson quarks coupled with an RG-improved glue. The bare gauge and quark anisotropies corresponding to the renormalized anisotropy < = a,/at = 2 are determined as functions of p and K, using the Wilson loop and

We consider recent progress in algorithms for generating gauge field configurations that include the dynamical effects of light fermions. We survey what has been achieved in recent state-of-the-art computations, and examine the trade-offs between performance and control of systematic errors. We brie

We discuss the implementation of a Sheikholeslami-Wohlert term for simulations of lattice QCD with dynamical Wilson fermions as required by Symanzik's improvement program. We show that for the Hybrid Monte Carlo or Kramers equation algorithm standard even-odd preconditioning can be maintained. We de
