Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

At the same time, going overboard with the number of Threads also seems to be a bad idea. What about using 3 threads for RTX 2080 Ti. An Intermediate value between 2 and 4. Maybe a sweet spot. Markyoung: how do you position yourself to try 3 threads instead of recent experiment with 2 threads? Yes ...

Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

How many threads do TCEC and the other one (chess.com ?) tournaments use with Lc0 ? Good question. How many GPU's are being used? My understanding is that you want two CPU "worker threads" for each GPU that the system has. [EDIT] It seems that AllieStein at TCEC is running on 2 GPUs and Threads is ...

Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

logically it should be more for a RTX2080 ti. Yes, that would explain mwyoung recommending 4 Threads, as he has a 2080 Ti. At the same time, going overboard with the number of Threads also seems to be a bad idea. One should find the correct balance. Is using an odd number of threads a bad idea ? I ...

Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

Because any more than default may hurt raw performance. Lc0 has many default settings. So I am not allowed to change them because it MAY hurt raw performance. Are you saying I must test Lc0 at default only. Even when my setting are stronger for Lc0. Or in your mind is there certain settings I am al...

4 threads for Lc0 = exercise in futility.

And so with your ponder match.
You always say this. But you can never answer why. Why is using 4 threads a exercise in futility?

Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

I will tell you. If you are setting Lc0 for maximum NPS. You are on the wrong path. NPS with Lc0 is a false flag. I tune it by time to depth and GPU loading. I ignore NPS results. Tuning Leela according to depth is a very bad idea and it's pointless and dangerous. Dangerous that you will end up wit...
