Re: Leela Chess Zero and what is the "Best" Graphics Card.

Assuming the same CPU frequency we know Stockfish yields only some tens Elo if we grow the number of physical cores from 16 cores to 32 cores, to 64 cores... meanwhile the nps grows together with near the number of cores. The enhancement in Elo is more lower if we use the virtual cores (HT) to grow ...

Re: Leela Chess Zero and what is the "Best" Graphics Card.

The Elo of an NN engine is determined mainly by the measure of NN and the quality of learning process. Supposing optimal learning process the main factor remains the measure of NN. Inside of NN the main bearing of the knowledge of an NN engine is the value head. If the two GPU have such a high power...

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

As I suspected, I can see Lc0's depths, but not the auxiliary engine's, which means no comparison can be made, in terms of depth reached with a fixed time per move TC. This is not the part of Leela's pv. The reached depth obviously depends on the value of the fixed movetime, the speed of PC and the...

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

Where do you get that "go movetime N" is independent of engine and HW? A faster engine will reach higher depth with the same allocated time, similarly, faster HW or a higher thread count will have the same effect; you must know that. Please, read once again my post about my test. Can you post a gam...

The large majority of games are decided in the middle game and not in the endgame.
That would be in line with what I recall from Laskos' test, you won't happen to remember which thread that was, will you?
Without tests of Laskos it is an old experience.

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

A fixed movetime gives much higher search depths in endgame and does not depend on the chosen engine, the used hardware and the number of threads. Where do you get that "go movetime N" is independent of engine and HW? A faster engine will reach higher depth with the same allocated time, similarly, ...

Re: about the term of equal hardware

I think quality of hardware can be measured by time to be able to do a specific chess task with the best software that is possible to write. Possible tasks: 1)calculating perft function(number of possible games of n plies from a given position). 2)finding the shortest mate. I read that gpu is relat...

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

I plan to add support for "go movetime N" instead of depth Why "instead"? Because the fixed depth-solution, LeelaFish has now, makes absolutely no sense: A fixed movetime gives much higher search depths in endgame and does not depend on the chosen engine, the used hardware and the number of threads...
