#2> The new prototype has 160 TB of shared memory spread across 40 physical nodes, interconnected using a high-performance fabric protocol.
So basically something similar to RDMA scaled to 40 nodes, 4 TB RAM per node.

#3Interesting to see ARM starting to become datacenter worthy now. It's cheap and there is a version geared towards any application you can think of. Now let's see HPE use some FPGAs with embedded ARM CPUs. That would really be the killer for all the smaller shops that are building similar exabyte systems.

A lot of it is the big customers can go to a chip company and say "I want this SOC, with X, Y, and Z" - and if they want enough of them, will actually be able to get them at a reasonable price.
I read this is why Qualcomm did their data center chip - some of the big Chinese companies wanted it.

#5Wasn't the Machine supposed to be a memristor computer? Did they ditch the project?

Based on HPE's website, it looks like they're going to be making their fabric part of this:

the article is pretty weak, people have built rdma machines that size before, and there have been architectures that allow for direct memory addressability of that size before.
so i have to assume the latter. that seems to be borne out by the little information i can find...addressable persistent memory is clearly a theme. but i haven't found any discussion of what kind of latency hiding mechanisms might be at play and what kind of consistency model is being used. will keep looking for anything detailed an authoritative
(edit - this seems to be pretty relevant https://www.labs.hpe.com/publications...but i don't know how much of it was speculative and how much was built...after all the security papers, there are some about concurrency control)

The Next Platform has had many articles with bits of detail on HPs Machine. Unfortunately, they don't really have any tagging mechanism, but you can search the phrase "the machine" or look at related articles there.

AFAIK there was licencing issues with memristors - in usual forward thinking HP way, they exclusively licenced the tech to someone else, who did no work on it, so it was not ready for the machine.
The IP is also a joint asset of HPE and HP Inc, so that sounds like something I would avoid baking into my product if I was HPE

#10Not enough.
Because, you know, there happens to be something else that is driven by memory. I'll give you a hint as to what it is: it's comprised of approximately a hundred billion units. (And no, it's not a galaxy.)
Divide 160 terabytes by the number I just stated, and you'll find that that you only get 1.6 kilobytes per unit. Not really enough (or at least, too close for comfort).
Step up your game, HP! :) But, this is a VERY good start.
