A kinetic Ising model was proposed for studying phase separation driven by surface diffusion. This model was referred to as model S, and consisted of the usual Kawasaki spin-exchange kinetics (model B) in conjunction with a kinetic constraint. Multi-spin coding techniques were used to develop fast algorithms for Monte Carlo simulations of models B and S. These algorithms were use to study the late stages of pattern dynamics in these systems, and compare properties of the evolution morphologies, e.g., growth laws, domain distribution functions, and spatial and temporal correlation functions.
