  • So, trying not to dox myself, I worked with the architect twice.

    Knights Ferry was derived directly from Larrabee (GPU), P54Cs with pre-AVX-512, .

    KNC was a die shrink with more cores. Both of these were PCIe accelerators only.

    KNL had full Airmont Atom cores with smt4, basically meaningful cores with proper AVX-512. Also you could boot them with linux, or as a PCIe accelerator.

    KNM jadded ML instructions, basically 8/16bit float and faster SIMD.

    They cancelled KNH.

    I interviewed some of the actual Larrabee guys, they were wild, there was a lot of talk about dynamic translation, they were trying to do really complex things, but when people talk like that it makes me think they were floundering on the software and just looking for tech magic solutions to fundamental problems.

    Intel always dies when the software gets more complex than really simple drivers, it’s their achilles heel.

    KNL also had the whole MCDRAM on package for basically HBM bandwidth, but that didn’t actually work very well in practice, again due to software issues (you have to pick where you allocate, and using it as an l4 cache was not always effective).









  • Hmm… Would a corporate entity accept such a return?

    They do, on a daily basis.

    How many multinationals invest in r&d for one of their subsidiaries.

    The country is investing in something that a subcomponent of it will benefit from, as will its taxpayers and trade balance.

    Why does private capital gets special treatment and has requiremets to provide economics return to the owner while taxpayer’s fund are treated like free money to increase returns for the owners of private capital.?

    I’m not saying it should.

    You’re conflating the definite problem of socializing risks vs privatizing losses with the clear benefit of investment in domestic r&d.

    There should be a payback to the taxpayer, and btw, there actually is in that the engineers working those jobs pay taxes.

    The corporations MUST pay more taxes, I am 100% on board with that, but don’t conflate that with the overall benefit of r&d investment.

    We are literally arguing over something that only exists because the government invested in it to the detriment of phone companies who wanted to keep charging ludicrous rates for leased lines and long-distance calls. You need to get over black and white.

    Just recognized your username, nvm, wasting my breath.
