(SVE isn't 512-bit SIMD like AVX512.) I don't know what BLAS they're using, though I know they've long worked on their own, but BLIS has gained SVE support recently, for what it's worth.
SVE is whatever width the chip designer wants, Fujitsu's implementation is 512-bit according to AnandTech

I'm not sure what predecessors that means (ThunderX2?), but these have been carefully "co-designed" for the job with experience from K Computer. Actually that's for a set of job types, which is part of the point. They also have extensive capability for low precision, if you want that. Note that it's not just at the top of top500, which is relatively uninteresting, but wins, or is up there, on things like HPCG, some s…
TX2 is from a different company though (Cavium -> Marvell). I guess the "predecessor" of the A64FX would technically be some SPARC chip that Fujitsu used to build?
Anyone know the reason for the dominance of Power processors in the top 10 other than it's from IBM and they get a lot of contracts for HPC?
They're fast, have lots of memory and IO bandwidth and can do some cool other tricks (I can't remember the name right now, but they have thing for PCIe devices to participate in cache coherency, their in-system protocols scale better to more CPUs, ...)

What would that look like? Shifting to becoming a software developer and leading the charge a Desktop Linux? A vertical integrator like Apple, Microsoft Surface, System 76 (yes those are varying degrees of success)? I really like the NUC products. They have the knowledge and skills to do everything (cpu, ram, soc, radio/wifi/cell (or used too), storage) in house but industrial design (maybe they do). I have never per…
I am hugely appreciative of Intel's substantial contributions to the Linux kernel, which is obviously software.
Being able to run Linux natively on modern Intel laptops with full 3D hardware acceleration, modesetting, and working suspend/resume using mainline drivers has been a game changer for decades. Without their stepping up and setting an example here, I doubt we'd have amdgpu today, desktop Linux use in general would be far less possible.

>Heat management of these systems will become the major contributor for environmental pollution Here's an idea, maybe we should just turn the moon into a giant data center?
In a vacuum the only way to dissipate heat is radiation and to a lesser extent conduction. In an atmosphere you also have convection. It's more efficient to cool something on Earth than on the Moon. We also have more power options on Earth. On the Moon you'd only really have solar power available and then only two weeks a month. On Earth you've got insolation for half a day every day and the option of other renewable…
Eh, the moon is made of pretty cold rock.
> two weeks a month
> half a day every day
Amortized, that's the same thing.

They have their own silicon (obs) and their own NUC hardware.
I’d love to see that all come together into a really polished platform.
Linux shines when the hardware had good, open source drivers available.
The end of the US semiconductor industry is now in sight. The only US owned state of the art fabs in the US belong to Intel. Intel survives because they have a high margin on x86 CPUs. Today, TMSC announced 5nm, and the top supercomputer is ARM-based. Apple seems to be going ARM. Chromebooks are ARM. Microsoft now offers Windows on ARM, on the Surface Pro X. Mobile never used x86. x86 is on the way out. What's left f…
According to https://en.wikipedia.org/wiki/Usage_share_of_operating_syste..., about 80% to 90% of the desktop and laptop computer market (counting the share of Windows + Linux devices in these categories). Intel won't starve.

CAPI
Really wish Fujitsu sold a developer kit with an A64fx chip - its the only shipping ARM chip with SVE that I know of and I would love to get my hands on one to play with.
IIRC the extension was specifically designed by Fujitsu for their needs, so it is not surprising.
