36-core chip developed that has its own Internet

Excerpt:
Rather than having a single wire bus connecting the cores together, this chip only connects each core directly to its neighbors. Just like the Internet, if you want to communicate with a core on the other side of the chip, you need to route that message through multiple cores to get there.

By using such a method each core isn’t sat waiting to send a message, they can send lots through multiple connections and know that the network will get it there.

Sorry, this article is not only poorly written but lacked the very basic understanding of processor bus design. AMD nor Intel has used the single shared bus for quite some time; AMD developed HyperTransport (HT) in early 2001 and has not looked back; HT supports multiple links between processors, much like this article describes. Intel has adopted their own point to point link bus much like AMD, Intel QuickPath Interconnect (QPI) which first appeared in 2008.

the article is a tad sloppy.. The internal internet they describe is really just routing kind of like ospf implemented on the die to manage traffic between the cores. Which in and of itself if actually pretty damn sweet..
