Hello,

Based on this recent publication http://onlinelibrary.wiley.com/doi/10.1002/jcc.23501/abstract
NAMD2.9 stumbles compared with gromacs and an improved version of charmm on a large system (465404 atoms and 500 cores).
Any ideas as to the cause of this dramatic difference in speed between 256 and 400 cores?

Brian
