Mainstream processors can effectively use AVX-512 .. in about 5 years

The entire thing was born out of the larabee project, when that project was about rendering. What Intel found was that no matter what they did they could not feed that much data to the CPU without changing the cache architecture, and that such changes to the cache architecture would negatively effect regular performance with crushing memory latency.

So we end up in a situation where Intel knew that they would not be able to process entire AVX-512 registers in one go on all threads, so did not include the execution units necessary to do it even on a single core, let alone have the bandwidth to do it on all of them.

So as Linus rightly notes, the shit is more or less useless right now, and costs a lot of execution time because AVX-512 registers are enormous and like all registers need saving between context switches, saving that is slow because of that lack of bandwidth. A single AVX-512 register is as large as all the general purpose registers combined.

The drawbacks are less-clear, but very apparent: graphics cards are rated to 300 watts. You're now trying to stuff a portion of that processing power into the CPU, and back in the early 2010's, benchmarking showed this to cause the CPUs to run VERY hot. Much hotter, much more quickly than the heat sink could cool them. (I worked at a computer manufacturer -- running Prime95 with AVX instruction set would regularly cause problems.) Apparently, from other comments, the CPU also doesn't have the memory bandwidth to fetch the data quickly enough. Remember, graphics cards use High Bandwidth Memory now to supply up to 1500 shader cores. Really, with AVX, the memory bus can't keep up -- unless you're doing thousands of iterations over the same, cached data, you can do one instruction and then you have to wait.

that’s a pretty that’s actually quite a funny subplot two this whole thing is how the whole Office of Net Assessment thing works. You know, it appears to be just a way to funnel money to informants and other people who are useful to the government. And essentially what they do, and I actually talked to some people who contributed to some of these reports, the ONA will pay somebody like $50,000 for a report on say China’s position in the world right now, right? And, and what the American will do is they will call up some person in a foreign country and offer them peanuts to put together basically a bunch of text around open source material, they send it back to him, he compiles it into a big document, sends it back to the Pentagon, does basically zero work and makes probably 10 times what the highest paid journalist in the world gets paid to do that same kind of stuff. So it’s pretty amazing. It’s amazing little subplot to the whole thing.

Sitting among peers at a gathering a few years ago, an exasperated Silicon Valley CEO seemed ready to get rid of Slack. “It’s one of my biggest regrets,” he said.

The app was fueling drama inside his company, and he wondered aloud whether it was worth the trouble. From a few feet away, I was surprised to overhear anything other than the often-repeated mantra that Slack would replace email. Yet since then, more executives have privately confessed concerns about how workplace chat apps were upending their cultures.

In short, identity determinism has become an additional layer of oppression, one that fails to address the problems it clumsily articulates.

Anyway, women are taking over everything, most of them crazy. Along with Rachel Tension and Oprah, we’ve got that Clinton woman that’s even older than Ann Coulter and probably sleeps all day in some cave, hanging by her toes, and Elizabeth Warren, that used to be a Injun but cured it with a shot of DNA. And now we’ve got Joe Biden, who ain’t nothing but a titless Hillary on days when he can remember who he is, and pretty much nothing at all the rest of the time. Which might be a good reason to vote for him. We’ve had a long string of Presidents who did know who they were, and it ain’t been real satisfactory.

Is the Church truly less essential than a laundromat? Live streaming the services does not impart God’s grace in the same way the Mystical Supper imparts God’s grace. Christ’s Church is an essential institution far beyond a drug store or gas station, yet we continue to allow the government to tell us this is not so. How can the Church ever reclaim her position as the grace-imparting institution founded by Christ Himself, while allowing the government to declare us a non-essential service?

Is the forced shutdown of our public services really about a virus, or is it something more? Looking at the actual deaths directly related to the coronavirus is not any different than a serious flu epidemic, yet certain elements within our society would have us believe it is indeed a direct threat to the whole of our society, and even the world. Not even the communist revolution was able to declare the Church as a non-essential institution.

His point is that social distancing is at least as much a political measure as a public health one, realized so easily because it has been pushed for by powerful forces. Some are straightforward vested interests. Mr. Agamben notes (without naming him) that the former Vodafone chief executive Vittorio Colao, an evangelist for the digitized economy, was put in charge of Italy’s initial transition out of lockdown. Social distancing, Mr. Agamben believes, has also provided Italy’s politicians with a way of hindering spontaneous political organization and stifling the robust intellectual dissent that universities foster.
