[gmx-users] stability of the simulation

[Dmitry Kovalsky]

Hi,

I have noticed few times that trajectories from the one tpr file but computed 
on different hardware could diverse significantly. (i.e. RMSD of Ca atoms 
after 7 ns of the simulation is 1.6 and 0.3!!!).

What for the difference could be attributed?
Does this mean that one cann't investigate dynamics of a protein from a single 
run?

Dimitry
