From length scale distributions characterizing frozen amorphous domains, we relate the s ensemble method with standard cooling and aging protocols for formin0 glass. We show that in a class of models where space-time scaling is in harmony with that of experiment, the spatial distributions of excitations obtained with the .v ensemble are identical to those obtained through cooling or aging, but the computational effort for applying the s ensemble is generally many orders of magnitude smaller than that of straightforward numerical simulation of cooling or aging. We find that in contrast to the equilibrium ergodic state, a nonequilibrium length scale characterizes the anticorrelation between excitations and encodes the preparation history of glass states.
