Not really... the general procedure is the same, but the names for things
change a bit.

I'm not aware that there is one. In general, doing meaningful and fair
comparisons is difficult because the performance of all such codes is
strongly dependent on system size, hardware attributes, which algorithms
you want to use and how much effort has gone into optimizing them. Still,
the general observation that GROMACS will be faster on a single-processor
machine is true. You should try it yourself on your hardware and see.
