A dedicated computer for Ising-like spin glass models

Abstract We present a parallel machine, based on programmable devices, dedicated to simulate spin glass models with Z 2 variables and short-range interaction. A working prototype is described for two lattices containing 312 × 312 spins each with an update time of 50 ns per spin. The final version of the three-dimensional parallel machine is discussed with a spin update time up to 312 ps.
