Cern has recently posted this new preprint. The publication is a report prepared for the European Committee for Future Accelerators (ECFA) containing an assessment and future plans for high performance computers in the field of lattice theory. Topics covered include hadronic spectroscopy, thermodynamics, quark masses, non-OCD physics, and algorithms and computing technology required for high performance lattice calculations. The preprint can be downloaded in either .pdf or .ps format.
