Re: Strange Lc0 TCEC performance

Finally they have found the issue, apparently the GPUs were severely got overheated(the case was too small and had just 1 fan for 2 GTX 1080 Ti, 500 Watt with 1 fan in a small case!) and affected in a big way nodes per second(there were even cases with 75% reduction of normal nodes per second), per...

TCEC should replay all the game played by the NN network then !
That would be a parody.
So better to stick to unfairness(to 2 NNs) than parody.

Re: Strange Lc0 TCEC performance

As you all can see, the TCEC performance in DIv 3 of Lc0 with both nets, ID10520 and Deus one, is severely underpar from what we know having ordinary hardware, say reasonable home CPU and GPU. So, what happens? TM, "too few games" and other things seem lame excuses. Is there a serious a bug affecti...

Re: Something goes wrong with lc0 since yesterday?

Re: Leela is more Chess-domain specific than regular Chess engines

Leela without history is weaker than with history(even with 1-2 plies history) so better to run your tests with a PGN from the start position ending to the desired position or probably equivalent for Leela, from a PGN with a FEN 2 plies before the desired position and playing the 2 moves to reach th...

Re: Something goes wrong with lc0 since yesterday?

Can't really believe this so far. :D Lc0 10520 has so far a 3570 CCRL 40/4 Elo performance after 50 games. :shock: :shock: Will continue till 100 games like with 10480. Lc0 Test10 10520 after 50 games has 3571±89 CCRL 40/4 Elo Program CCRL Elo Error(cl 95%) Games Score Lc0! Test10 10520 3571.0 ±88.5...

Re: Something goes wrong with lc0 since yesterday?

Re: Leela will use Net 10480 in TCEC Div3

So who knows what kind of other BS is in that "test". Currently 5 draws from 5 games, meaning the guy running the test realized there was some obvious crap in his first test and restarted it and then he is selling a story of PGN that he forgot to save!?!? How naive one has to be to believe that? Ho...

Re: Leela will use Net 10480 in TCEC Div3

I have very small samples at longer time control, but it might be that the newest nets are even stronger than ID10480 at LTC. In fast games they are similar, but at 600'' + 10'' time control I used, the small samples are: Lc0 on GTX 1060 6GB Deep Shredder 13 on 4 i7 cores 3.8 GHz Lc0 ID10474 vs Dee...
