I don't see the benefit of annealing. A big challenge (with any simulation) is
sampling, and a single run of increasing temperature leaves you waiting for a
long time (because you need sufficient time at each temperature) and you still
only have one run. If all one cares about is temperature dependence of
dynamics, I'd just simulate N replicates at each temperature, independently, and
acquire data in a much more efficient manner.
