โœฆ Synopsis


Pure SU(4) gauge theory is simulated by Monte Carlo methods on an 8~lattice. The method of Metropolis et al. is used to equilibriate the space-time lattice. All Wilson loops up to size 4 x 4 are calculated. Because of memory requirements we work on the 2 Mword CDC CYBER 205 at Colorado State University and take full advantage of the parallel processing capabilities of this vector machine.

Lattice gauge theory is a technique for studying quantum field theory free of divergences. All the Monte Carlo computer calculations up to now have been performed on scalar machines. A technique has been developed for effectively vectorizing this class of Monte Carlo problems. The key for vectorizin
