[gmx-users] At what point is the random seed generated?

[Trayder Thomas]

Hi,
When using 'gen-seed = -1' at what point is the random seed assigned?

e.g. Does it use the process ID of grompp and embed the seed number in the
tpr file, or does it use the process ID of mdrun?

I ask because I have 50 identical simulations started from the same tpr
file :(

Thanks,
