Re: Dual RTX 2060 for Leela

I installed two RTX 2060 (Gigabyte Windforce OC) into my Ryzen7 1800x 8x4000 MHz PC and I made some tests. I used Leela version 0.21.1 for tests. 1. test: Net 11250 1a. test: Default parameters GPU1 setoption name backend value cudnn-fp16 go nodes 1000000 Result: max nps = 22533 (depth 10 time 1540...

Re: New results in the ERET chess test

Fire 7.1 behind Critter, Laser, Fizbo, Booot, Andscacs, Xiphos, Sting, Deep Shredder and Ethereal? Critter 1.6 better than Fritz, Equinox and Gull? Deep Shredder 13 better than Xiphos? And so on ... Looks like a lottery. Not to me. The probability of an engine that is 200 elo better to be in a bett...

Re: my Lc0 spreadsheet

Are we sure Lc0 & A0 use the same definition of "node"? No, but it's quite possible. Also, I was thinking of the upcoming TCEC superfinal, where the effective Leela Ratio (as defined in the paper) is close to 1.0. According to my results, Lc0 t40 should win. According to the results of Hugo, it is ...

Re: TCEC Simulation program

Hello! I created a program for the simulation of TCEC: https://github.com/sovaz1997/TCEC-Simul Offer your ideas for improvements or optimization. The program downloads the game schedule of TCEC (in JSON format) and predicts the result based on this. You set the ratings and the quality of the simula...

Re: my Lc0 spreadsheet

Leela Ratio is in deed hard to estimate. I would say mine is average 1.1. From the startpossition Stockfish with 12 cpus has about 18.000 kNs in 1-2 Minutes and Lc0 24.000nps - 25.000 nps. So this is 1.2 ratio. But when I observe the games, SF is far over 20.000 kNps after very few moves, while Lc0...

Re: New results in the ERET chess test

Looks like a lottery. Quite the contrary: the list appears to be remarkably well-corelated with playing strength. The above-mentioned German-language article says "surprisingly accurate" ( überraschend genau ), and personally I cannot but agree. Frankly, I thought such tests are outdated now, but c...

Re: my Lc0 spreadsheet

Why ponder ON? How may cores your CPU has? If only 12, then "ponder ON" will harm the game-play. The "effective" in-game Leela Ratio is not that easy to calculate and I am sure it's not 1.1 at all. A0 team in their _paper_ (not the earlier preprint) spoke of in-game average or median performance, n...

Re: my Lc0 spreadsheet

Hi all I started a spreadsheet with my direct comparison between Stockfish 100419 12cpu and Lc0 NN 40 on Rtx 2060- Leela Ratio is 1.1 Games are played with ponder ON and 5min + 3sec. Each match is 100 games. Every two days, a new network will be added. So it will grow up fast. https://docs.google.c...

Re: Dual RTX 2060 for Leela

Basing on the common test data before we can make a list of RTX 2000 line GPUs. The common parameters are: NET: 11250 Backend: cudnn-fp16 Minibatchsize: 512 NNcachesize: 2000000 Other parameters are default The list: RTX 2060 OC max nps = 28646 (corres) RTX 2070 non-OC max nps = 29357 (Laskos) RTX ...

Re: Dual RTX 2060 for Leela

Also, forgot to mention, those results in your list are for different engines, ... This is the only point in which you are right. But the position of GPUs in the list are independent of the Leela version. Only the concrete nps value may change. Every parameters can be found in the "My non-OC RTX 20...
