While some interviewees seemed resigned to feeling they could do little to influence politics, others found it frustrating β almost as though political news coverage were rubbing their noses in issues over which they had no control. Many saw avoiding political news as part of a larger strategy for managing their emotions. Rather than engage with news that would leave them feeling sad about the state of the world and frustrated about their own impotence to change it, they chose to conserve their emotional energy to focus on their own problems.Anything that doesn't help you with your own problems is worthless to you. Most of this site is really just writing practice for me; which is why there are long stretches where I don't post here.
Mainstream processors can effectively use AVX-512 .. in about 5 yearsAnd another:
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.Just buy a GPU, dork
thatβs a pretty thatβs 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 Chinaβs 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 itβs pretty amazing. Itβs amazing little subplot to the whole thing.The world of government contracts is indeed a hilarious subplot
Sitting among peers at a gathering a few years ago, an exasperated Silicon Valley CEO seemed ready to get rid of Slack. βItβs one of my biggest regrets,β he said.Use the professional boundary eraser to instantly make all your most productive employees run afoul of facebook psychosis. Now you are only left with idiot losers. Congratulations!
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.
