A number of important physics questions can be decisively addressed using established techniques in lattice QCD with Teraflops-scale computer resources. In particular, evaluation of hadronic weak matrix elements critical to extracting CKM matrix elements and realistic studies of the QCD phase transitions should be possible. A collaboration of nuclear and particle physicists, MIT computer scientists and Lincoln Laboratory engineers are proposing to design and construct such a Teraflops-scale machine, one of whose applications would be these lattice QCD calculations. The machine will be build upon the current Thinking Machines` CM5, using advanced packaging and synchronous DRAM technology to achieve a 10X boost in performance per node. The machine will have a peak speed of 2.6 Tflops, a memory of {1/4} Tbytes and should sustain {approx}1.5 Tflops when computing a Dirac propagator on a 128{sup 3}x256 lattice.
