The MDGrape guys might have a thing or three to say. They have been demonstrating some pretty awesome performance for years.
True, but my impression was that they were focused on getting the most performance from one unit, while the DEShaw approach factored in a high degree of parallelization from the beginning.
I've heard the talk in Dresden earlier this year and I liked hearing about an idea that I've also had some time ago but not heard talking about on this list: interconnect hardware being able to DMA directly to/from CPU cache. I don't know how useful such a feature is for a general purpose interconnect (or MPI library) but it certainly fits well in the specialized frame of molecular dynamics (or rather, of how MD is implemented today).
