Lattice QCD results from the CP-PACS computer
We present physics results from large-scale simulations of Quantum Chromodynamics (QCD) on the space-time lattice carried out with the CP-PACS computer. The CP-PACS is a massively parallel system with a peak speed of 614 Gflops and 320 Gbyte of main memory developed at the Center for Computational Physics, University of Tsukuba.Since the start of full operation of CP-PACS in October 1996, precision calculation of the light hadron spectrum in the quenched approximation of QCD and a systematic attempt at a calculation without this approximation have been pursued. Physics motivations of these calculations, the computational difficulties,and advances brought in by the CP-PACS are discussed. Performance of the CP-PACS for lattice QCD computations are described in a companion paper by S. Aoki et al.
