摘要

Preliminary results from a hadron spectrum calculation of quenched Quantum chromodynamics on a 32(sup 3) (times) 64 lattice at (beta) = 6.5 are reported. The hadron spectrum calculation is done with staggered quarks of masses, m(sub q)a = 0.001, 0.005 and 0.0025. We use two different sources in order to be able to extract the (Delta) mass in addition to the usual local light hadron masses. The numerical simulation is executed on the Intel Touchstone Delta computer. The peak speed of the Delta for a 16 (times) 32 mesh configuration is 41 Gflops for 32 bit precision. The sustained speed for our updating code is 9.5 Gflops. A multihit metropolis algorithm combined with an over-relaxation method is used in the updating and the conjugate gradient method is employed for Dirac matrix inversion. Configurations are stored every 1000 sweeps.
