Bundles?

Would it be worthwhile to add a section of standalone programs that include the stockfish engine? --Guy Macon (talk) 00:49, 27 December 2016 (UTC)[reply]

How many stockfish developers?

How many stockfish testers? — Preceding unsigned comment added by 178.91.105.24 (talk • contribs) 08:15, 17 January 2017 (UTC)[reply]

Nov 2017 tourney

Stockfish won the Chess.com Computer Championship held Nov 13-16. The ref is here: 1--Billymac00 (talk) 13:16, 19 November 2017 (UTC)[reply]

I added a brief section on this tournament.—LithiumFlash (talk) 19:38, 12 December 2017 (UTC)[reply]

Stockfish versus AlphaZero

So a program using thousands of GPUs[1] and god knows how many custom Tensor Processing Units[2] beats stockfish running on a fairly ordinary desktop PC. And this is notable...how? --Guy Macon (talk) 20:51, 8 December 2017 (UTC)[reply]

More like one machine with 4 TPU for Alpha Zero. -Koppapa (talk) 07:14, 9 December 2017 (UTC)[reply]

Source? --Guy Macon (talk) 11:21, 9 December 2017 (UTC)[reply]

"We evaluated the fully trained instances of AlphaZero against Stockfish, Elmo and the previous version of AlphaGo Zero (trained for 3 days) in chess, shogi and Go respectively, playing 100 game matches at tournament time controls of one minute per move. AlphaZero and the previous AlphaGo Zero used a single machine with 4 TPUs. Stockfish and Elmo played at their strongest skill level using 64 threads and a hash size of 1GB." -- https://arxiv.org/abs/1712.01815

Max cores?

How many cores does this engine support? Windows 10 x64 supports upto 256 logical cores and I guess this is the same for Stockfish? Beatitudinem (talk) 20:48, 19 January 2018 (UTC)[reply]

From [3] (Readme.md):

This version of Stockfish supports up to 512 cores. The engine defaults to one search thread, so it is recommended to inspect the value of the Threads UCI parameter, and to make sure it equals the number of CPU cores on your computer.

Not sure if this applies to all operating systems. Regards,--Voorlandt (talk) 21:18, 19 January 2018 (UTC)[reply]

Fide rating?

Can Stockfish earn or be assigned a FIDE rating? Hollarbohem (talk) 03:31, 12 August 2020 (UTC)[reply]

I don't think FIDE rates engines. If you want to know what Stockfish's rating should be if FIDE did rate engines, that's a complicated topic since elo rating depends on who else is in the pool of players. That (as well as the fact that engine strength depends on hardware) is why Stockfish's elo can range from 3500 to 3800+ in different rating lists. Banedon (talk) 03:44, 12 August 2020 (UTC)[reply]
