[gmx-users] Clovertown vs Woodcrest gromacs experiences?

If anyone has some gromacs benchmarks numbers they'd be willing to 
share from clovertown
quad cores. ..  we're having to decide between buying 3.0 ghz DPDC 
woodcrest nodes (which
we already have several of and are quite happy with) vs 2.66 ghz 
DP/QC clovertowns for the same price.
I haven't seen any clovertown results in the benchmark page or in 
past listserv messages. .

Obviously, we don't  expect the clovertowns to scale perfectly for 
single jobs due to the architecture, but I'm very
curious how they do with multiple jobs on the same node - we tend to 
run lots of independent trajectories of medium
(~100,000 atom) sized systems in our lab.

If anyone can share their experiences with gromacs on clovertown XEON 
systems it would be greatly appreciated!
