The QCDOC project has developed a supercomputer optimised for the needs of Lattice QCD simulations. It provides a very competitive price to sustained performance ratio of around $1 USD per sustained Megaflop/s in combination with outstanding scalability. Thus very large systems delivering over 5 TFlop/s of performance on the evolution of a single lattice is(More)
We examine a two-stage lot scheduling problem with waiting time constraints and distinct due dates. Wafer lots in diffusion or etch processes generally have due dates specified for each process stage. Some lots even have more strict time constraints that their waiting times between two or multiple stages should not exceed specified limits. We also wish to(More)
