[AMBER] Parallel pmemd.cuda: any preliminary cross-node tests?

The question is primarily for Ross and Scott.
Have you been able to implement any parallel code for pmemd.cuda? If so,
how does it look in multiple node situations and how much bandwidth is
needed to keep all cards fully utilized?

I wonder whether DDR infiniband would be sufficient to maintain
performance across several nodes or is this the case for QDR. If you
haven't tested it yet, what's your best guess at this point?

Thanks for any feedback
