Linux creator moans
Linux creator Linus Torvalds was back on form while talking about Advanced Vector Extensions 512 (AVX-512) found on select Intel processors.
To be fair, Torvalds did not go all Mr Sweary on Chipzilla, but he did have a few words about the compiler instructions Intel is enabling for Alder Lake and Sapphire Rapids.
Torvalds said that the Alder Lake instructions being flipped on in GCC right now make no mention of AVX-512 but only AVX2 and others, likely due to Intel pursuing the subset supported by both the small and large cores in this new hybrid design being pursued.
The lack of seeing AVX512 for Alder Lake led Torvalds to say: "I hope AVX512 dies a painful death, and that Intel starts fixing real problems instead of trying to create magic instructions to then create benchmarks that they can look good on. I hope Intel gets back to basics: gets their process working again, and concentrate more on regular code that isn't HPC or some other pointless special case."
