[gmx-users] Experiences with Gromacs scaling on US supercomputer centers?

Hi all,

I'd be interested to know about people's experiences with Gromacs on
US national computing centers.  Which machines have it set up to scale
best?  We're putting in an XSEDE request soon, and I'm trying to
figure out which resource to request.  Our system is
semi-coarse-grained, using
reaction field electrostatics, so we don't have to worry about PME.
Of course, couldn't hurt to know about PME scaling as well.   I'm
scalings with 100K - 300K atoms.

Of course, best performance will probably change with 4.6 because of
all the setup tweaks, but let's start with 4.5 scaling info!
