We determine the time-evolution of the Loitsianski integral at high Reynolds numbers by computing an ensemble average of a large
number of independent large-eddy simulations of decaying isotropic turbulence. We find that the Loitsianski integral becomes
proportional to t^{g} at large times and that g is approximately 0.25. Our simulations illustrate the efficient use of
massively parallel computers for simulating large ensembles of turbulent flows.
