Abstract: (Elsevier)
We describe the program SZINHUR which performs a Monte Carlo measurement of properties of lattice Quantum Chromodynamics. It uses the Quasi-Heatbath updating algorithm, which is known to reduce the correlations between successive sweeps through the spacetime lattice giving a performance improvement by a factor of roughly two over the tenhit Metropolis procedure. The program measures the Polyakov loop and its correlation function. The program is highly vectorized and runs on a one-pipe CDC CYBER 205 at a speed of 53 μsec/link, which corresponds to an average computation rate of 93 Mflops. The program would run at almost twice this speed on a two-pipe machine.
