Re: Can Leela use 2x RTX gpus?

No, I am saying it doesn't scale up with more cores at all . In fact, you will lose performance with more cores, not gain. But for the example I gave - dual 2080 Ti - 3 cores is clearly faster than one. I'm not sure I follow your point. Nor do I understand yours. I told the OP that slow clocks were...

Re: Can Leela use 2x RTX gpus?

Using chessbase 15 gui? Using chessok Aquarium gui? What should I do? Google and see where this has been asked many times before Done, but still some guys have speed problems to reach more nps, not like it would be 2 gpus. The CPU they have is also a factor. Slow core clocks will hurt performance, ...

Re: The problem with adjudication based on score

Try this one in your favorite chess engine and you will see the problem immediately (unless some engine scores it zero): 7r/6p1/7P/p1r1p1k1/Pp1pPp2/1PpP1Pp1/2P3P1/K6R w - - I did not send this to an engine, but am wondering what the problem is.

Re: Test sets results on opening, tactical, ending

middle phase test positions - have you considered ECM (Encyclopedia of Chess Middlegames)? There is a cleaned up version of this test suite available (ecmgcp), see https://arasanchess.org/tests.shtml. --Jon Ah that is interesting! How up to date it is? I bought one from Chess Informant a couple of ...

Re: What engine breaks even with GMs in blitz?

In blitz (let's say 3' + 2" or as close to this as possible), the top engines today are far beyond human level. But how far down the list do we have to go to find engines (and specified hardware) that score evenly against GMs, preferably ones with known identities and ratings? I'm sure there is ple...
