[gmx-users] Different energy using the identical tpr file

[Fahimeh Baftizadeh]

Hello,

I have a 2 tpr files which are identical. Then I am doing a single step MD
(I put n_step=0) simulation just to compute the total energy of a certain
configuration.

These tpr files give me different energy values ... when I run it on my
computer or on another computer. Even the gromacs version is the same in
both computers. I compiled gromacs identical in both computers.

Can you help me to figure it out?
Thanks
