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.
I'm pretty sure there's an emulator, which is how you usually do early development.

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…
> heat dissipation Eh, the moon is made of pretty cold rock. > two weeks a month > half a day every day Amortized, that's the same thing.
The Moon might be solid rock but that doesn't make it a good heat sink. If solid rock was a good heat sink you could just build data centers inside mountains on Earth orders of magnitude cheaper. Rock might eventually dissipate heat but it's not conductive enough to carry it away from heat generating elements to keep them from melting down.
Renewables on Earth include solar, wind, hydro, tidal, and geothermal. Even if your data center was 100% solar you only need enough storage to cover night usage and maybe a few days of total cloud cover. A grid tie is also trivial. A data center on the Moon requires two weeks of power storage and has no grid tie option.
Again, this is all ignoring the literally astronomical cost of getting mass to the Moon.
If you want expensive but non-polluting data centers you'd get more bang for your buck building them on or under the ocean with renewable power attached. A barge or submerged platform with ocean water for cooling anchored off-shore would provide orders of magnitude better latency and be orders of magnitude cheaper.

#213CoreTeks on youtube has a great video that explains the brilliance of this chip.

That video is from end of 2018... which makes it even more amazing.

#214The 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…
I can't disagree more. The US semiconductor industry is more vibrant than ever. Intel reported record quarter every quarter for the last 2-3 years. Fabless semiconductors are doing better than ever - nVidia, AMD, Apple, Qualcomm, Google TPU etc. Most of the high performance ARM SoCs come from Apple and Qualcomm, both American companies.
Commodore reported 7-year record revenue/profit 4 years before going bankrupt. https://dfarq.homeip.net/commodore-financial-history-1978-19...

The EUV machines are made in the US.
Netherlands is 7000km off your guess.

Weird. I clearly remember their guy boasting about this in a video on YT.
Also your troll bait is totally off.

#217We're living in an age in which AWS dwarfs all the machines on the TOP500 taken together. The TOP500 is a vestige of the cold war that needs to be retired. Similarly to how the US and the USSR used to compare their numbers of nuclear warheads, it is comparing a reserve of capacity that is probably going to be retired having brought marginal benefits at best, all in order to goad taxpayers into a futile competition.
Well there obviously is interest in running simulations and other HPC applications on systems of public commercial cloud providers and there are specialized offerings including high performance interconnects, GPGPUs, large memory VMs and schedulers. Don't expect the largest of the top500 clusters to be replaced anytime soon by such, but for lesser demands people will be maintaining spread sheets and calculating the b…

>Intel reported record quarter every quarter for the last 2-3 years.
Due to high demand on people needing 30%+ more processing power after they lost 30% perf due to Spectre/Meltdown. When they get the manufacturing and supply up to a resonable standard, they'll start building inventory and start selling cheaper chips again. Margin and ASP will decrease, and investors will sign out

ASML's manufacturing plant is in Wilton Conneticut.
R&D is done in Netherlands, with some manufacturing.

#220Green500 #1 is MN-3 by PFN that's also from Japan and they also use original chip!
