What does the memory interface look like for this? None of the papers I can find indicate how you can get so much parallelism out of the CPU memory interface. An interesting approach to non-Von Neumann computing is to put ALUs in memory, to take advantage of the fact that DRAMs have far more internal bandwidth than what is exposed in traditional systems: http://researcher.ibm.com/researcher/files/us-leejinho/tvlsi...…

Yeah thats the big black box titled "magic happens here" in their diagram. Maybe something like HBM2?

From a layman: Would this necessitate a different programming paradigm?

Yes, it's mentioned on page 2 of the article (you may have missed it was two-paged)

Yeah, that's a design choice I just don't understand. The article is already lengthy, what improvement does splitting it to pages manually give? I completely missed the fact that it's multiple pages.

Thanks! I did miss that page. But even though they mention "... calls for the development of software tools to help programming the new architecture...", I'm still unsure as to how programming for such a processor might look like.

In the old days this technique was used to get information about number of people who found the article interesting enough to read the next page, all without JavaScript. This of course assumes that readers notice the "next page" link, where is where they seem to have failed (or maybe the expectations of readers have changed so much that the new breed of readers no longer notice such links - quite possible).
