Re: Questions about graphics cards for Leela

On Phoronix they have some Leela tests: https://www.phoronix.com/scan.php?page=news_item&px=LCZero-NVIDIA-Benchmarks And Radeon cards: https://www.phoronix.com/scan.php?page=article&item=radeon-vii-linux&num=9 The second link doesn't say but I don't think the 20x0 cards were not run with fp16, whic...

Re: Questions about graphics cards for Leela

As a sidenote, people with a smaller budget should take a look at the GTX 1660 , which supports the FP16 option, but not raytracing reflections: https://www.nvidia.com/en-us/geforce/news/geforce-gtx-1660-ti-advanced-shaders-streaming-multiprocessor/ Interestingly, it has extra hardware components f...

Re: Lc0 GPU load

I think he was having reliability issues with all 6 GPUs and found that it runs well with 2, per the subsequent posts at the link

Re: Trying out the Leela Hybrid engine (NN with AB)

It is easy. However, Leela still has a fairly strong "zero" goal; that is, minimal chess-specific coding. Of course, a chess opening book would be quite contrary to the zero principal. If you don't want to provide some log info, perhaps you can use a different GUI. If on Windows, Winboard would be f...

Re: Trying out the Leela Hybrid engine (NN with AB)

I'm not familiar with that GUI.

Perhaps you could try it with Polyglot logging enabled to see what messages pass between it and the GUI.

-log true -lf logfilename

I forgot to mention earlier that it is extremely unlikely that Leela will ever support her own book, at least for quite a long time.

Re: Trying out the Leela Hybrid engine (NN with AB)

That is odd. Polyglot should work in place of any UCI engine regardless of the GUI.
What GUI is it?

Also, the .exe inside an .exe incurs almost no overhead relative to the engine actually searching for a move.

Re: Trying out the Leela Hybrid engine (NN with AB)

Just wondering why Polyglot with a book does not work for you.
Thanks

Re: Training the trainer: how is it done for Stockfish?

Simple question of a non-programmer of chessengines: Is it possible to combine some code of Lc0 with SF in one engine (could be easier to handle then LeelaFish) to get all advantages both systems (AB and NN - tactic and strategic behavior) deliver? SF can run on CPU and Lc0 on GPU simultaneously......

Re: Asus tuf z390 + core i7 9700k

I have been quite happy with the Noctua NH-D14. It's a big boy, so not all cases will have room, but it has been keeping my OC'd i920 cool for years. No idea how it ranks with today's top coolers. I suppose water cooling would be better, but I'm an old IT dinosaur and water still makes me very uncom...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

There is far more art and science (and exhaustive testing) in creating and improving a mere "bean counter" engine than you might think (SF for example). As far as developing a plan, this has eluded 50+ years of chess programming until recently. Unfortunately, while the trained nets have a "plan", we...
