Dear Gromacs Users
I have done simulation of one protein in different computers such as
GPU(tesla C2075), cpu and cluster(two different nodes with 32 processors)
for 5ns. I got different rmsd values for the same protein, but I used same
minimized structure in all the computers. My question is what could be the
reason for the different rmsd? You can find the rmsd graph in the
