Re: Lc0 Vs Stockfish Match.

I would be shocked if Lc0 wins the current super final. In my testing Stockfish is stronger then the 3xxxx NN of Lc0. I will be equal as shock if Lc0 does not win it all in the next season. I have been charting the progress of the 5xxxx NN of Lc0. And its growth in strength is impressive. Just in t...

Re: Knight equals 48 pawns?

If you scroll towards the bottom you'll see two graphs. I'm not sure if this helps.

Your doubt that doubling GPU power doesn't have the same effect as on an AB engine is correct.
I also don't understand this comment. Going from 1 GPU to 2 should yield around 50 elo.

Re: how to run Lc0 on two RTX 2070 ?

By contrast the world's fastest machine today - Summit - runs at 143,500 TFLOPS, which is 4000x faster than the Earth Simulator (or fast multi GPU box).

I hope it does something more useful than calculate how to nuke other countries...

Re: how to run Lc0 on two RTX 2070 ?

Yeah had another look: A dual 2080 Ti is about 27 TFLOPS (single precision - I assume that's that the Top 500 is measured in?) In June 2002 there was a massive jump as Japan came out with its mighty Earth Simulator (35 TFLOPS!!) blowing away its nearest competitor. I remember this coming out and bei...

Re: how to run Lc0 on two RTX 2070 ?

Chessbase has article about building two RTX (2080?) machine and claim: There is one interesting thing to consider: if I had had this machine around the year 2000 it would have been the most powerful computer in the world! Really? Apparently so. The fastest machine was the Lawrence Livermore Nation...

During recent weeks I‘ve had so much fun with LC0 and watching it play.
So I want to give many thanks to the developpers.
Me too. Computer chess has become interesting again. This may be even better than the Rybka days (for those that enjoyed that!)

Lc0 using exactly the same settings as the Feb 2019 TCEC, on 2 x 2080 Ti fails to get this in 14 minutes: Analysis by Lc0 v0.20.2TCEC2019: 2.Qg5 Kh2 3.Qe5+ Kh3 4.Kf2 e1Q+ 5.Qxe1 Be2 6.Qc3+ Kg4 7.Qd4+ Kf5 8.Qd5+ Kf6 9.Qd6+ Kf5 10.Qc5+ Kg6 11.Qd6+ Kf5 White is slightly better: +/= (0.40) Depth: 10/22 ...

Re: how to run Lc0 on two RTX 2070 ?

Hi there does anyone know how to run Lc0 on two RTX cards? Are they automatically detected? Or is there a need for setting up parameters? If so, which one. How many RTX cards does Lc0 support? thx in advance for help. C.K. You will need a motherboard that supports sli. You will need the sli bridge ...

Re: Knight equals 48 pawns?

It's definitely not showing probability odds, like Alpha Zero? Nothing wrong with converting win probs to scores in pawn units, we do the same in Komodo MCTS. But we don't output nonsense scores like this. Looks like no one bothered to check whether the conversion formula made any sense. Test 50 lo...
