Abstract
We study the Metropolis dynamics of a simple spin system without disorder, which exhibits glassy dynamics at low temperatures. We use an implementation of the algorithm of Bortz, Kalos and Lebowitz [1]. This method turns out to be very efficient for the study of glassy systems, which get trapped in local minima on many different time scales. We find strong evidence of aging effects at low temperatures. We relate these effects to the distribution function of the trapping times of single configurations.

Let us stress that the true problem, of course, is not auniformly low acceptance probability (which could be repaired by simply choosing a large value of Δτ), but the existence of dynamic relaxations on a variety of time scales
