[gmx-users] 35% Variability in Simulation Performance

[Mitchell Dorrell]

Hi all, I just ran the same simulation twice (ignore the difference in
filenames), and got very different results. Obviously, I'd like to
reproduce the faster simulation. I expect this probably has to do with
automatically-tuned parameters, but I'm not sure what is really going on.

Also, any tips for further boosting the performance?

Thank you for your help!
