Many thanks for your reply. I've got following reply from my question from Linux-PowerEdge mailing list. I was wondering which one applies to GROMACS parallel computation (I mean CPU bound, disk bound, etc).

Although the question is a bit fuzzy, I might be able to give you a

Had or SUSE Linux as factory installed OS-es. If you have any of

Parallel runs are little bit different story and depends on the
interconnect. If you have Infiniband, than you'll have a very good
scaling over multiple nodes. This is true especially if it's the I/O
cards are the Mellanox QDR-s.
