Interested in creating, playing and testing your own chess engine?
you can have a look at openbench maybe, https://github.com/AndyGrant/OpenBench . It is currently a testing framework for chess engines (only invited ones) or fishtest. https://tests.stockfishchess.org/tests Stockfish testing framework. Both of these test if change A beats the master version using statistics. Both look at the git repository and download it and create/compile the engine, that might be another solution for you.

~20TBs on Striped Hard Drives / RAID0: What kind of hardware to support this setup?
FishTest has thousands of computers running 24/7 https://tests.stockfishchess.org/tests. Nerds at gcp,aws,universities burn thousands of GPU hours on lc0-client just to watch their GPUs warm up. They aren't just attaching 20tb of endgames to an old macbook.

Does (human + computer) combo beat computer?
if removing any rng from stockfish would gain elo it would be merged. If you think it gains elo feel free to submit a test to https://tests.stockfishchess.org/tests , but it doesn't so what your saying makes no sense.

What are some chess960 positions that are winning for white
Where did you get these numbers from? https://github.com/glinscott/fishtest/wiki/Regression-Tests shows an elo difference of 351.3 elo points. This is further exaggerated by the fact that sf9 lacks nnue and is particularly weak at the starting position and consequently 960 starting positions.

What makes SF15 better than 14? I mean, what do they do/program to improve performance?
You can see the various code changes in https://github.com/glinscott/fishtest/wiki/Regression-Tests . Both the actual change and the elo change from the code change.

Stockfish 15 is ready!
Current progression test is still in progress but you can see all of the previous ones here: https://github.com/glinscott/fishtest/wiki/Regression-Tests

Chess-GPT's Internal World Model
> The problem is that a stockfish based bot knows some very strong moves, but deliberately plays bad moves so it’s about the right skill level.
What are you basing this on? To me it seems like difficulty is set by limiting search depth/time: https://github.com/lichess-org/fishnet/blob/master/src/api.r...

What is the deep of analysis of stockfish in lichess?
The LiChess documentation indicates how many nodes are searched: https://github.com/lichess-org/fishnet/blob/master/doc/protocol.md

Initial eval graph doesnt change after subsequently increasing depth
The eval graph comes from an analysis done by fishnet. The analysis that you see changing is done locally in the browser on your device. That is why there is a difference.
-
Is Lichess getting slower for people?
YOU can help by running this: https://github.com/lichess-org/fishnet
- January was a month of records for Lichess 🎉 - 147,000 concurrent players - 161 million games played - More than 4 million active users - Almost as many new accounts created as November and December combined - 4 billion games in the Lichess DB - Such an amazing start to 2023!
-
Why is Lichess analysis limited to 15 CPUs for me?
Game analyses are made in a distributed way, but only accepted from users they trust. You can check the tool they use for that here and they instructions to use it.
-
chess.com analysis of the same move in back-to-back games
It's not on the user's device and not on their servers. The game analysis is done by fishnet using donated CPU time.
-
If Chess.com made all of their premium features free, would you prefer it over Lichess or would Lichess still be better?
You can run a program on your computer, so that Lichess can run Stockfish analysis using your CPU https://github.com/lichess-org/fishnet
