@love_reading50 I'll say what I said elsewhere too - most of these were a result of the original kthread approach to handling async offload, which in hindsight was a mistake. That code base is no longer available in even 5.10-stable (and nothing newer), so that attack vector no longer exists.

While everyone is enjoying all the #AMD #Zen4 performance reviews, here is my teardown of Zen4's #AVX512 implementation and architecture. tl;dr - Intel has some serious competition now. mersenneforum.org/showthread.php…

@RickPalaciosJr SFR bubble? I bet these are from all speculative home investments, that bought at the peak and now want to pass their over-priced payments to tenants. These will quickly come down, wages have not increased this much!

IMO the two most important transformations for performant code are Array of Structs to Struct of Arrays and Loop Fusion to Loop Fission. The 1st is essential for cache perf and the 2nd breaks data dependencies and often unlocks more optimizations that were not obvious before.
@fleming_matt Used to be fairly popular approach even in computer architecture, not too long ago. E.g. lca.ece.utexas.edu/pubs/HPCA_SPEC…

I tweeted this before, but feel the need to tweet it again: The blog that @andrey_akinshin runs at aakinshin.net/posts/ is probably the best "applied statistics for the performance engineer" blog out there.
