The civilian application proposed in the article, mapping the many to many relationships between amazon purchasers and items purchased, is unsettling.

That doesn't need anything special in terms of hardware so it's a bad example, current hardware is well capable of making those connections.

Can't wait for this publicly funded research to make some private corporation billions!

Not sure if sarcastic or sincere. You can damn near predict what will be the future tech 10 years down the line based on what DARPA is doing to make killing more efficient.

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...…

Manufacturing logic on the same wafer as DRAM is difficult since the processes are so different. On the other hand, manufacturing on separate dies and connecting with an interposer or TSVs gets you tremendous bandwidth and relatively low latency; this is how some newer generation graphics memory is implemented (see https://en.m.wikipedia.org/wiki/High_Bandwidth_Memory ).

But logic and SRAM are more compatible. I'm still curious because multiple processors having random access to a large memory is not easy. The scratchpad they mention sounds like a cache, but maybe it's something more than that.

Earlier quoted context omitted.

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.

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).

It was used for ad impressions. Each page read = new ads = more $$ for the publisher.

Is it just me or is the illustration of 'graphs' of totally the wrong kind of graphs? I'm sure they don't mean bar charts.

Yeah, they missed including a pie chart and a gantt chart for good measure.

Most of the industry has moved on to Deep Pie Charts.
