[gmx-developers] repeatability of runs?

[Shirts, Michael R. (mrs5pt)]

Hi, all-

Is anyone else having issues with repeatability of runs?  When I start
from the same tpr using one thread (to avoid load rebalancing) on the same
machine, I find that it diverges after the first step.  It appears to be
an issue with the virial.  Any thoughts?  It seems like the code should be
binary repeatable at this level.  Makes it hard to debug a problem!

Best,
