We measure the sweep-to-sweep autocorrelations of blocked loops below and above the deconfinement transition for SU(3) on a 16 4 lattice using 20000-140000 Monte-Carlo updating sweeps. A divergence of the autocorrelation time toward the critical β is seen at high blocking levels. The peak is near β = 6.33 where we observe 440 ± 210 for the autocorrelation(More)
A parallelization study of Quantum Chromodynamics (QCD) simulation on a nondedicated computer, AP1000, is reported. AP1000 is a highly parallel computer with distributed memory. Data communication is fast not only among the nearest neighbor processing units, but also among long distance ones. We study SU(3) quenched QCD simulation with lattice sizes of 32 4(More)
