Re: [gmx-users] Can a Serial MD simulation be continued in, Parallel?

Only if you tell it to As it says in the documentation (for example, man grompp), you can supply the magic information for continuing simulations from the .edr and .trr files to either grompp or tpbconv and achieve exact restarts. Make sure you read the caveats on that manpage on the contents of your .mdp file.

There must be a numerical perturbation to your model physics in doing so - you're adding up lists of numbers in different orders - but the effect should be negligible within the MM approximation.
