Re: Chess.com 2018 computer chess championship

You are correct. Found the link. Thanks. Thanks for this thread. Looks like a very interesting tournament. Have some kind and generous souls here created a game archive or a PGN file complete with games from this [chess. com] tournament? At the end of page 7 in this thread, Ted alias AdminX, provid...

Re: Chess.com 2018 computer chess championship

Also, seldepth=3. Max tree size is <= 256^3. Its not a ponder bug, its a hardware issue. Andrew, May I quote you from CCCC chat? A handful of engines (5) are randomly locked out of thread access, causing their trivial depth 1 searches to take well over a second, when usually they are < 1 micro seco...

Re: Ethereal 10.88 NUMA

I don't understand. My engine has not any NUMA code at all. To be run in a system with 2 processors with 6 core each one it doesn't seems to need NUMA code. Does it need some NUMA awareness code? How much do you think it will gain? Isn't this a OS problem to equally allocate threads to the 2 cpu? O...

(And lest you assume I'm not a fan of Leela, I'm actually a huge fan of the project. That's why I want Leela to achieve dominance in an environment that reasonably approximates fairness, without much room for griping and grumbling, and not because of a 60:1 effective hardware cost advantage .)

Re: Chess.com 2018 computer chess championship

Andrew,

Feel free to send the NUMA version anytime, I'd be happy to make some time and run it on the server at a high thread count for you, maybe a couple games...

But it can"t be until later this week, or this weekend, because we're planning to test Lc0 RC2 next.

Re: Chess.com 2018 computer chess championship

Norman, I feel like you have done this test knowing the results beforehand ... I'm sure you know that on a Windows machine, without special Numa code to handle 64+ threads, the threads are left on the same processor group. Furthermore, if I were to send the latest Ethereal, that Numa support does e...

I never saw anything besides the download symbol which is a link to 'download pgn'
and this always resulted in plain moves.
I'll look into it and try to take care of it asap.
