Computer simulation as a technique for studying many body physics is nearly as old as electronic computers. The 1953 paper by Metropolis et al1 introduced what has become a standard technique for simulating complex systems in equilibrium at some finite temperature, T. In the past, useful simulations could only be performed on the largest, fastest, and most expensive computers. The advent of powerful super-mini computers has brought large scale simulations within the reach of most academic research groups in the U.S. in the last few years. This trend is accelerating, via microcomputers with speeds approaching one million operations per second and memory capacities which should soon reach a million characters or more. When these computers become available, in the next few years, they are expected to cost about the same amount ($10,000 – $40,000 US) as does laboratory electronic equipment.
