A fast vectorized program for the CDC cyber 205 to simulate the ising spin glass in three dimensions

Abstract We describe a computer program that performs the Metropolis algorithm for the three-dimensional (J = ±1) Ising spin glass problem at a peak speed of 80 million spin updates per second on a 2-pipe CDC CYBER 205. Title of program: GLASS Catalogue Id: ABDA_v1_0 Nature of problem Equilibrium configurations of the three-dimensional Ising spin glass model are generated for 64 arbitrary (+-1) bond distributions using a highly vectorized code and multispin coding.
