  • yes, as i said

    from the article it’s not clear what the performance boost is relative to intrinsics

    (they don’t make that comparison in the article)

    so its not clear exactly how handwritten asm compares to intrinsics in this specific comparison. we can’t assume their handwritten AVX-512 asm and instrinics AVX-512 will perform identically here, it may be better, or worse.

    also worth noting they’re discussing benchmarking of a specific function, so overall performance on executing a given set of commands may be quite different depending what can and can’t be unrolled and in which order for different dependencies.


  • from the article it’s not clear what the performance boost is relative to intrinsics (its extremely unlikely to be anything close to 94x lol), its not even clear from the article if the avx2 implementation they benchmarked against was instrinsics or handwritten either. in some cases avx2 seems to slightly outperform avx-512 in their implementation

    there’s also so many different ways to break a problem down that i’m not sure this is an ideal showcase, at least without more information.

    to be fair to the presenters they may not be the ones making the specific flavour of hype that the article writers are.




  • this is a complex topic and probably belongs in a different thread.

    essentially i don’t personally believe in punishing citizens of a country for the actions of its politicians.

    at best its misguided, at worse it basically empowers politicians on both sides who draw power from friction between citizens of different nations. typical divide and conquer bs.

    why do you not think a software developer wouldn’t have to

    wouldn’t or shouldn’t? if you mean wouldn’t, it’s not surprising and its not the dev’s fault they have to comply with policy, so the criticism is not with them.

    if you mean shouldn’t, i don’t agree with punishing athletes either, but regarding foss specifically, isn’t the “friendly competition” of olympics equivalent to that? sort of. in some ways yes. in other ways its actually the opposite.

    collaboration is actually the opposite of competition.

    and while there’s a case for the benefits of healthy sports competition, i don’t believe it truly fulfills the spirit of international goodwill to the degree it says on the packaging. foss and other forms of international collaboration for the betterment of greater society are definitely on a higher rung - in my opinion at least.
