Description

Abstract In 1985 an efficient multitasking version of the SU (3) lattice gauge theory algorithm for the CRAY X-MP was published by Kuba and Moriarty [Comput. Phys. Commun. 36 (1985) 351]. Here we present an upgraded microtasking version, which reflects the development of the CRAY multiprocessor systems over the last 8 years and achieves 8.3 GFLOPS on 16 processors of the CRAY Y-MP C90. Title of program: SU3 Catalogue Id: AABT_v2_0 [ACNO] Nature of problem The use of nonperturbative computation techniques to study strongly interacting matter requires the discretization of the continuous space- time on a 4-dimensional lattice. Then the quantum field theory is formally equivalent to a statistical mechanical model that can be simulated on a computer by Monte Carlo methods. This program is a microtasked implementation of the multihit Metropolis algorithm on a CRAY Y-MP multiprocessor system. It calculates the Wilson loops of size up to L/2 x L/2 for L ...
