So yes, I love GMX to the point of using it for stuff it was never intended to do. I also hope you'll forgive the fact that my postdoc is using LAMMPS. ;)
With the input keys you suggested, we are at almost 400 ns/day, compared with 270 with the earlier version -- and that is close to a 50% boost from -pme gpu. A colleague just walked in and I shared the bottom of that md.log. Expletives of awe and admiration were loudly exchanged. We're doing the upgrade for my 8-year old desktop-turned-linux-box with a single puny GTX 960 -- just because it would be dumb not to. Hats off to you guys, very well done.
