The temperature dependence of the microstructure and local dynamics in the paramagnetic phase of the d = 2 and d = 3 {+-} J Ising spin glass model is examined by comparing the equilibrium distributions of local flip-rates and local energies calculated in large-scale Monte Carlo simulations. The emergence in this model of fast processes as the glass transition is approached corresponds with recent experimental results.
