We measure accurate values of the inter-quark potentials on a 48 3 56 lattice with SU(2) pure gauge theory at β = 2.85. The scale is set by extracting the string tension -we obtain √ Ka = 0.063(3) at β = 2.85. From a careful study of the small-R potentials in the region 2 GeV < R −1 < 5 GeV, we extract a running coupling constant and estimate the scale Λ MS = 272(24) MeV.

We present results for heavy-light decay constants, using both propagating quarks and the static approximation, in O(a)-improved, quenched lattice QCD. At β = 6.2 on a 24 3 ×48 lattice we find f D = 185

We present the initial results from the FHPCA Supercomputer project at the University of Edinburgh. The project has successfully built a general-purpose 64 FPGA computer and ported to it three demonstration applications from the oil, medical and finance sectors. This paper describes in brief the machine itselfMaxwell -its hardware and software environment and presents very early benchmark results from runs of the demonstrators.
