Sapling 1.1.3 permantly grabs a thread #11

Open CPagador opened 3 hours ago

CPagador commented 3 hours ago

I run tournaments with ponder off and 1 thread per engine. Through Task Manager I realized Sapling always use a thread, even when it is not his turn. Is there a way to disable it? The GUI is set to ponder off, of course.

Regards, Carlos

Hey Carlos! Thank you so much for including Sapling in your tournament, I can't wait to see how it performs! I can assure you it's not thinking whilst it isn't it's turn but I think I know what the problem may be.

It will be this loop: https://github.com/Timmoth/Sapling/blob/fc41d026d0e6d5bd8f34d1eb652eaee2cb4ab907/Sapling/Program.cs#L115

It's waiting to receive a command but It's extremely inefficient and essentially looping and checking if it got a message at a very high rate. It will be an easy fix. I'll get it done tonight and ping you when it's sorted.

Thanks again for alerting me of this!

@CPagador that should be fixed in v1.1.4 https://github.com/Timmoth/Sapling/releases/tag/Sapling-1.1.4

Please let me know if it's still causing you issues or if there are any other problems you've noticed.

Also would I be able to see the results of the tournament once it's complete?

Hi Tim,

Yes, you can follow the results here:

https://talkchess.com/forum3/viewtopic.php?t=84301

An older version compiled by Jim Ablett participated in the PL12, version 1.1.3 is competing in PL11. I'll use the latest version tomorrow, when PL10 starts. I anticipate to say that it will pass to the next phase because it is very strong. :D

Best regards, Carlos

P.S.: Could you generate an AVX2 and/or BMI2 binary? I think it could be faster on my PC.

It is working fine now. Thank you.

All binaries in the release make use of AVX2 / BMI2 (amongst other extensions) the vast majority of modern cpus will support the AVX256 version (e.g Sapling_win_x64.exe), but if your CPU supports AVX512 use that version since it will be considerably stronger! (e.g Sapling_win_x64_avx512.exe)

Oh yeah since 2024-09-19-47 it's a lot stronger at least +200ELO I'm very excited to see it compete in it's first tournament, I'll be checking in daily!
