Always there is a faster code: My current byte-#histogram results vs 2024
It is interesting, that how closer is #Intel #GoldenCove to the theoretical limit (0.343 <-> 0.372) than #AMD #Zen5 (0.207 <-> 2.54)
#GFNI
I gave up some old principles (e.g. no jCC & store uops), so the 256-bin histogram process of 64 arbitrary bytes is now just 41 uops.
More complex code, ~10% performance deviation due to the data content, but thus it exceeds the 2 bytes/clk rate (0.5 clks/byte in the old metric).

Done, this time with #GFNI:
It utilises the left-shift property of GF2P8MULB instead of VGF2P8AFFINEQB, asymmetrical (left shift 4, right 6 uops), slower than VBMI2, but portable:
ymm: hybrid ADL & RPL w/ GMT
xmm: TMT

@InstLatX64 Excellent stuff. Now all we need is the *variable* shift and rotate operations for bytes. 🤪
Re: #AVX512: finding-first-byte-in-lanes proposal

with #AVX512_VNNI and #GFNI there are compact 4-uops solutions for DWORD / QWORD cases:

I was truly inspired by the approach this forum took in unique, innovative sessions led by our various co-organizers and session leads last week. We must continue this great work and continue to take out-of-the-box approaches. Looking forward to the 2024 forum. #GFNI
@GFnuclear wrapped up in London yesterday, after 2.5 days of networking & collaborative, hands-on activities to advance leadership to drive a culture of #innovation.
@EPRINews staff is looking forward to the next #GFNI in 2024 &, with our collaborators and co-organizers.
Favourite comment so far at #GFNI is that #nuclearenergy needs the cultural change and innovation that its workers become its advocates.
Only they can change minds by sharing the excitement they feel about its benefits.
Here's something I wrote on that https://t.co/KoTf6nQUYy
RT @GFnuclear: THE COUNTDOWN IS ON to Global Forum for Nuclear Innovation, where delegates from across the globe will find ways for the #nuclear sector to play its critical role in meeting some of the greatest challenges facing our planet #GFNI #innovation
