I understand NAMD2.7b2 has the metadynamics patch included. I was wondering whether somebody who has used it before can comment on how well it speeds up convergence of rare events, and secondly whether one can use a multiple walker strategy with this metadynamics colvar module as is implemented in the NAMD/PLUMED compilation.
