dc.descriptionThe CP-PACS is a massively parallel MIMD computer with the theoretical peak speed of 614 GFLOPS which has been developed for computational physics applications at the University of Tsukuba, Japan. We report on the performance of the CP-PACS computer measured during recent production runs using our Quantum Chromodynamics code for the simulation of quarks and gluons in particle physics. With the full 2048 processing nodes, our code shows a sustained speed of 237.5 GFLOPS for the heat-bath update of gluon variables, 264.6 GFLOPS for the over-relaxation update, and 325.3 GFLOPS for quark matrix inversion with an even-odd preconditioned minimal residual algorithm.
