I must I missed the boat on this story. Several news stories have popped up about these devices and I did not point them out to you because I was of the impression they were confined to rather specialized tasks and machine configuration. That is not really true; or at least not as definitive as I thought it was. These devices have much broader application than I thought. And Cray obviously has a better handle on their usefulness than I did.
What's interesting to me is that they can be so easily mixed and matched into one's existing hardware. Done well, that yeilds startling increases in performance. They are server parts for now, but don't let that fool you. I'm rather certain they will appear in (at least) some high-end workstations. I wonder what will happen when, inevitably, some gamer gives them a whirl?
