  From length scale distributions characterizing frozen amorphous domains, we
relate the s-ensemble method with standard cooling and aging protocols for
forming glass. We show that in a general class of models, where space-time
scaling is in harmony with that of experiment, the domain size distributions
obtained with the s-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.
