Thanks, I'm glad to hear you enjoyed it; I've gotten a lot of positive feedback on this one. This was certainly one of my better articles (along with the X3 article).

I'm not 100% sure either. Obviously, you cannot use any form of ethernet for coherent traffic, nor can you use PCIe. There's no reason why you can't have the SERDES from one chip connected to another chip, but I don't know what you would run on top of said link. I believe that the diagram I used was showing a cluster; each chip would be a node, and they would be connected with 10GBE or whatever you want to use.

I can certainly ask though, but I don't really think it would make sense. They are in the embedded market principally, and they would probably want you to buy the higher end parts if you want more performance in a CC system.
