That make me CRAYzy

Fri May 17, 2019 7:36 am

Well this news is outright Cray Cray: https://www.marketwatch.com/story/cray- ... 2019-05-17

Hrmmm... Cray uses AMD chips in a supercomputer (confirmed).

HPE buys out Cray (confirmed).

The only logical conclusion is that.... AMD IS BUYING OUT INTEL DOUBLE CONFIRMED!!

MISSION ACCOMPLISHED!

(And you thought I was a harmless Intel shill. That's what I want you all to think. In reality I'm just an agent of chaos.)

Why would AMD want to buy Intel? They don't have all that many product lines that need to be cancelled.

It wasn't too long ago that HPE bought SGI and with it their NUMAlink interconnect. This merger has had some HPE product come from it (it also helped that HPE was previously rebranding a high socket count SGI box).

Cray is more puzzling. Cray of course does system builds but that is nothing special by itself and does overlap with HPE. Cray also provides their own fabric which also something that HPE does (thanks SGI and GenZ). This move feels more like HPE is simply buying out some of the potential competition. Curious what regulators will do.

I believe that HPE was also the division of HP behind the memristor that unfortunately has gone nowhere commercially. They had some truly innovative ideas for non Von Neumann architectures using the memristor, but you need to get the fundamental components working at scale first.

HPE is still doing some research. Gen-Z superficially looks like it was the child of their "The Machine" research efforts. The memristor itself was supposed to be part of "The Machine" but they never were able to produce them at scale for production as you mentioned. HPE so far has moved their persistent memory technology to something else (not sure what they're doing there but it seems to be different than Intel/Micron 3D Xpoint).

HPE has at least done something with the SGI acquisition as they used the acquired technology for the SuperDome Flex. Unfortunately HPE is not advertising any socket count beyond 32 on the SuperDome Flex systems due to the need for additional hops in the interconnect. They are still selling larger up to 256 socket boxes leveraging Broadwell. Memory capacity is one reason why the older system is still offered.

They have been in the news a fair bit lately, what with the big deals they signed with DOE. But yeah, most people seem to react with either "Wait, what, they aren't dead yet?" or "Who the heck is Cray?" (depending on age).
Nostalgia isn't what it used to be.

Well, there's the IBM/Nvidia partnership (which yielded Summit and Sierra). Not sure if they plan to continue pursuing additional systems using that architecture though. I'm assuming the only reason IBM got that design win was because POWER9 has native NVLink support baked into the silicon.

IBM builds machines that aren't usable for the workloads we require. I guess they can technically bid though. :P

Just out of curiosity, if you're allowed to say (and I won't be surprised if you can't... :lol:), what makes them unsuitable?

In as few words as possible: memory bandwidth to FLOPs ratio. We're lucky to get a few percent efficiency on standard CPUs, even under 1% on GPU machines.

So in other words, you're salary.

So after all your hours, your hourly rate come in at $25/hr ;)

Hourly exempt, with the same number of hours and project codes prorated depending on how much over regular hours. So it's like salaried, except mixed with the BS that goes with tracking hours as well.

The joys of being a government contractor. :)

I don't miss those days.

Getting chewed out for charging a bunch of hours to an invalid time code when that was the time code we were told to use was pretty aggravating. This happened repeatedly, on multiple projects.

These days I just deal with whatever issues people are screaming the loudest about this week (in between attending useless meetings), and collect a paycheck. :wink:

I didn't say the previous job didn't have those things. I just don't need to do the time reporting dance any more. :wink:

Did the time code you were "caught" by have the numbers 22 in it? :P

I don't think this will ever stop happening till the forecasting part of budgeting is fixed. That, or competent people handing out codes. I don't expect either soon. :)

I hated having to spend every week splitting our hours over the time codes we were asked to charge. Especially when the codes with the least money required the most hours of our time. The various Dilbert cartoons about that were right on target.
