@tromo @tuxbot then why this article? worse: "the complexity of AVX-512 means that such optimizations are generally limited to specific applications and require specialized knowledge of low-level programming."
so anyway, if I really got serious and scaled up this might matter, but my limitations are in setting up the job. Since I do lots of small clips, I am always the limiting factor, slowing everything down.
They have not found a fix for this, and I refuse medication.
@duval I didnt read it, I did it boost for the optimization that can be used with AVX even without SIMD commands (which needs low-level programming). Get a C program and compile it with -m avx2 -O this will enable the 16 more 64bit registers and will use them at optimization. This mean far less access to/from memory. @tuxbot
@tromo @tuxbot I used to compile my ffmpeg, and that would be a good experiment. I used to also compile liquidsoap, but I don't bother them lately, since now my specific problems are resolved well enough.
@duval btw, the AVX-512 it is too much, lets say avx3 with 512bit registers... forget it... AVX2 is far enough @tuxbot
@tromo @tuxbot I could probably compile in the optimization, but why bother?
@duval for speed... @tuxbot
@tromo @tuxbot ☕ yeah right
