Well, given that GPUs don't do so hot on Linpack, one should hope that
they're close to peak on *something* !

Heh. Is there a published linpack for some CUDA based solution? Or possibly code available?

For a while I was trying to incite some friends to go do a CPU that
plugged into VRAM, but it didn't get very far.

Well hopefully ATI and AMD will figure out a way to give a $300 CPU as much memory bandwidth as a $200 video card. Seems like with the continuing increase in cores, not to mention the yet again increased width of the SSE registers would make increased bandwidth more usable.

I'm pretty sure hypertransport allows for a significant number of outstanding memory transactions, so even a single gpu/cpu hybrid could farm out a 100GB/sec memory system to numerous sockets.... sounds like a good justification for HT3 to me.
