The GTX260 on the head node is wasted. Should it be moved to a compute-only node (n0005) ???
Test it first.
For a small system (5,500 atoms) : GTX460 → 0.032 days/ns, GTX260 → 0.034 days/ns.
For a slightly larger system (7,400 atoms) : GTX460 → 0.043 days/ns, GTX260 → 0.062 days/ns.
It should probably go …
