Average is at least 200% faster!

Re: Steroid Leela (2x faster leela) will be playing TCEC 20 Sufi
Does it play stronger?
The reason I ask is that Ceres did not do well in Pohl's testing.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Found this info:
Regarding our submission to SuFi:
• Given that it's unlikely, that Lc0 in the current configuration would win SuFi (don't let DivP fool you), it's quite likely that we'll send pr1483 binary there.
• PR 1483 is a port of one of Ceres features (parallel node gathering), implemented by Tilps.
• It gives ~+40% nps increase, at the cost of worse nodes selected (5 Elo loss at fixed nodes).
• It's also quite a tricky asynchronous code, so hang/crash-causing bugs are not unlikely -- it was tested reasonably well but only on a few configuration -- prepare for a drama.

This is not Ceres, just Leela.
https://github.com/LeelaChessZero/lc0/pull/1483
I dont know which built Pohl used. And there is no official release of Ceres yet.
Crem's fixed node test shows around 5 elo loss.

40% speed increase info was based on " Nav's machine" .
200% speed is based on actual TCEC machine by Aloril test.( TCEC gets more benefits from this version because there is severe cpu bottle neck with 2.5 GHZ machine)

I think Pohl used the "all in one" clump someone made available.Nay Lin Tun wrote: ↑Thu Jan 14, 2021 12:33 amDann Corbit wrote: ↑Wed Jan 13, 2021 9:52 pm Does it play stronger?

It seems logical that re-coded as C++ it should do much better.
I am keen to see the result.

Re: Steroid Leela (2x faster leela) will be playing TCEC 20 Sufi
The download for cudann is 270 MB, but only lc0.exe with 3 MB is changed . I got promising results even with GTX card:
SF was classic, but 4 cores.
Code: Select all
1 Lc0 v0.27.0-rc1 +18 +20/=82/-14 52.59% 61.0/116
2 Stockfish 12 -18 +14/=82/-20 47.41% 55.0/116

What were your results with 0.26.3 like?

About 50% for Lc0. Different nets have no big effect. I used J94-80.
