Re: Leela Chess Zero 42565 vs Stockfish 140619

You can't let Lc0 get feeded by CPU time already used on stockfish. Something has to be adjusted to account for that. Correct. And it is obviously not or lc0 would not run. There is more then one way to do things. Your issue is you assume things that are not true. And trap yourself in a mental box....

Re: Leela Chess Zero 42565 vs Stockfish 140619

I give up. Sorry to here that. The next time you don't know. Just Ask before attacking someone because you dont know everything. And there is more than one way to do thing. And some are better then others depending on the work load. You want to carve out CPU cores and that is one method. Some want ...

Re: Leela Chess Zero 42565 vs Stockfish 140619

Please explain why you choose to overload your system with 32+2 threads? First I am not overloading my system. As you can see from the live stream. Let see if you can figure this out on your own. I will give you a hint. How many threads is your compuer running right now. 8-core at 4.5GHz. That was ...

Re: Leela Chess Zero 42565 vs Stockfish 140619

Well, it doesn't seem to serve any purpose to use more threads in total than the number of HT provided by the hardware. So with 16 cores, 32 HT I would put Leela on 1 core, (HT 0 and 1) stockfish on 14, (HT 2-29) and reserve 1 core (HT 30-31) as a 'noise buffer' (as it seem to me it would make very...

Re: Leela Chess Zero 42565 vs Stockfish 140619

Pondering makes sense when playing against Leela on a many-core machine, as Leela wouldn't use many CPU threads while thinking, and all other threads would then go to waste. Likewise the GPUs would be idle during Stockfish' turn when Leela is not pondering. If Leela need two unshared cores, you can...

Then again the question that arise is if ponder is good trade-off for more time :?:
Exactactly.

Is 6% CPU cost to stockfish worth pondering. You tell me...

Current move prediction rate of this current ponder match is 57.9%.

And stockfish likes it very much.

Re: Leela Chess Zero 42565 vs Stockfish 140619

Wery well. I PM'ed Graham whether he'll try ponder on his dual xeon motherboard. Graham's engine games is watchable in playchess server. Permanent brain enabled make a lot more sense on an dual socket mobo than single cpu motherboard. That is not correct. But dual socket is still ok. AMD 2950x and ...

Re: Leela Chess Zero 42565 vs Stockfish 140619

mwyoung: why can't you just simply adjust threads as per general consensus and everything is fine. Leave this useless test and thread, here is one proceeding right now using similar hardware, but in correct conditions (ponder = on): new testrun started with nn 42578 16 core XEON v4 PC, HT off 12 cp...
