Given that today's HPC architectures are mostly power constrained, and a majority of the FLOPS often come from GPUs (for their flop/watt ratios), this direction is not surprising. ARM has been making major strides in the high performance area. The new AWS Graviton processors are pretty nice from what I have heard. And then there's the ARM in Mac. Yup and Julia will run on all of these! While I say all of this, I shou…

Get ready for a surprise then: all those FLOPS are coming from the ARM cores.... This beast has no GPUs: https://postk-web.r-ccs.riken.jp/spec.html

I am really happy to have come across this post, mainly due to this fact.

Global Foundries New York fab (Fab 8), from Wikipedia: Technology: 28 nm and 14 nm. 7 nm planned. However, in August 2018, GlobalFoundries made the decision to suspend 7 nm development and planned production, citing the unaffordable costs to outfit Fab 8 for 7 nm production. GlobalFoundries held open the possibility of resuming 7 nm operations in the future if additional resources could be secured. So, not a state of…

Yeah, not "state of the art" technically, but that's where the first generation Ryzens (14nm) were made, which still feels like yesterday to me, haha. "14nm" is still good enough, especially considering Intel's "10nm" vaporware..

GF 14nm is still behind from Intel 14nm for actual size.

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…

> What's left for Intel? Well I'd like to see them go all in on Desktop Linux. But then I'm a dreamer.

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 personally experienced a software experience from Intel I have ever remotely enjoyed.

Edit: Actually there is software I have used from Intel that I have really enjoyed, the BIOS for the NUC. So I stand corrected.

Even more impressive than the linpack result (2.8x faster than the runner up) is the HPCG result at 4.6x the result of summit in second place.

That benchmark consists of more sparse matrixes which are a lot more realistic depiction of hpc workloads. Seems to scale a lot better with irregular access patterns than basically Nvidia GPUs on the other systems.

> While I say all of this, I should also point out that the top500 benchmark pretty much is not representative of most real-life workloads, and is largely based on your ability to solve the largest dense linear solve you possibly can - something almost no real application does.

They also publish the HPCG benchmark with sparse matrixes. And unsurprisingly an order of magnitude lower flops across the board. The Fujitsu chip scales a whole lot better than the usual Nvidia GPUs though.

We'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.

I don't think more than half a percent of taxpayers know about top500, and I don't think many who know even care how their country ranks.

Side story: HPC ranking is relatively common topic in Japan because previous K computer was targeted to cut budget by government and well reported by news.

A combination of: - sources available freely online - my own thought process and piecing of things together

What sources freely available online tell you that there are likely groups out there that have cracked AGI and are keeping it a secret?

You see Intel is a 50 yr old company, you think they will sit hand in hand on their bums? If the majority Industry shifts towards ARM ISA Intel will evolve, What stops Intel from Licensing the ARM Core and build a industry leading ARM Chip? I think no-one with the exception of Apple in the semiconductor industry has more resources than Intel to build a world class ARM CPU. Intel is just trying to drag x86 as far as possible because it can monopolise the architecture only AMD and Via are other two vendors who have license to build x86 processors.

By my eyeball, that adds up to maybe 12% probability by 2025. As evidence for your claim, that's... rather unimpressive, and less than convincing.

The link is working for me, here are the details on the winner. “The new top system, Fugaku, turned in a High Performance Linpack (HPL) result of 415.5 petaflops, besting the now second-place Summit system by a factor of 2.8x. Fugaku, is powered by Fujitsu’s 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors. In single or further reduced precision, which are often used…

There seems to be a difference between peak and useful . Be careful of marketing and hype. (I am not an HPC guy, just IMO).

It goes further than that. HPL is already a bad benchmark since it just prioritizes the narrow requirements of HPL(double precision multiplication and bandwidth). HPCC(https://icl.utk.edu/hpcc/) is generally regarded to be a better benchmark of the real value of a particular cluster for scientific use.
