Re: New lc0 v0.23-rc1 VERY FAST
Hi all lc0 users Do upgrade to the new lc0 v0.23-rc1. Its giving greatly improved speed and performance. My speed using the sergio NNs almost doubled ! It should be good for the other NNs too. Regards "New option --logit-q (UCI: LogitQ). Changes subtree selection algorithm a bit, possibly making it...

Re: Twin 2080Tis and large NN
for the games. It looks like the best CPU you played was a older 8 core 2700x CPU, and this game was a draw. I have not seen any data that suggest using multi GPUs with Lc0 is worth the investment at this point. But this could change.... Right now SF is just smoking Lc0 and the other NN in my testi...

Re: Twin 2080Tis and large NN
Large NNs (384x30) really do improve the performance of lc0( whether Laskos Sir fully agrees or not ). Of course, twin 2080 Tis help :) , but on the other hand using a large NN with a weak GPU makes no sense and would simply backfire. Following is a Game against a guy using 16 Cores and Stockfish.....

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 ...
