Re: Lc0 speedup using CUDA 11

I seem to get about a 15% gain in nps by upgrading to the latest CUDA 11 Runtime. But do not upgrade to cuDNN v8.0.1 RC2 (June 26th, 2020) for CUDA 11.0. That one reduces nps by about 50%.

It would be good if developer of Leela would let out the source of Leela without bugs.
This would be good for all software, everywhere.
Na jah
But it is a more serious issue if the bugs block the compilation of that program.

If you dont have v26 Leela engine, it is definately worth installing. Leela can see Mate in xxx now. ... V26 is just released after S18 TCEC, Here is someone's opinion regarding New Leela running in TCEC bonus games (copy from fishcooking post). "AFAIK nobody asked that TCEC use mainline openings. ...

Re: To contempt or not to contempt

Hi, Contempt is an interesting topic. We can make weaker engines in a rating list stronger if we give a negative contempt. We can make stronger engines in a rating list stronger if we give a positive contempt. So what is to do? Contempt = 0 for all. But we create a new problem with it!! Engine prog...
