Abstract
We discuss numerically the relaxation dynamics of a simple structural glass which has been quenched below its (computer) glass transition temperature. We demonstrate that time correlation functions show strong aging effects a nd compute the fluctuation dissipation ratio of this non-equilibrium system .
