Gromacs benefit greatly from low latency interconnects.

SCI interconnect together with ScaMPI has the lowest latency
of all. If you have a look at the performance pages at gromacs
www pages you will see a test performed by the Gromacs team, where
the very good performance of  SCI is presented.

Gigabit ethernet are great for interconnecting servers, but not
for interconnecting clusters.
See Scali www pages where more information about SCI/ScaMPI are
