I used Gromacs-3.3.1 to simulate a small protein in water.
I have used 2 and 16 CPUs to do the simulation respectively. But
I got the RMSD of the protein equilibrated to 0.15 nm in the 2 CPUs
simulation and 0.20 nm in the 16 CPUs one. Are these differences
In the 16 CPUs simulation, the RMSD of protein at t=0 was about
0.1 nm, why not equal to zero? I used the initial structure for the
least squares fit.
