Proposal - TLDRL - The Lower Deck Rating List, a Raspberry Pi RL

[dkappe]

The Raspberry Pi 5 is a brute. Aside from lc0 on GPU, all of the top engines will run on it. If you really want to make this in the spirit of the 4K challenge, pick a platform like the Pi Zero

Even that would be pointless. The Pi Zero has 512MB RAM, and SF16 needs 111MB with 16MB hash. You'd end up with the same order as CCRL, with the only difference made by whether an engine has good ARM optimisations.

For an actual challenge, you'd need to go to microcontrollers without operating system, such as Cortex-M4 which is used e.g. in dedicated chess computers like the Chess Genius Pro. But that fails because it doesn't run UCI engines.

Yes, agree, the Berry won't be a real programming challenge, but maybe an alternative to TCEC and CCCC for the average Joe.

From Ipman:

Code: Select all

1.360.718	Raspberry Pi 5 4×Cortex-A76 @ 2.4 GHz (ARMv8)	                4cores	pop-neon
  475.493	Raspberry Pi 4 4xCortex-A72(ARMv8) @1.5Ghz lpddr4 3200	        4cores	pop-neon

Maybe the Berry offers a good sweet-spot for all kind of chess-programmers, and, with Vulkan GPU. Just saying.

If someone can be found who's willing to pay (maybe put their name, or the company name, in the tournament name?), you could have a shared account on a cloud system like Google Compute, pick a hardware platform, and testers could use this shared account to run the games.

You'd want to keep an eye on the number of compute units each tester is consuming and ensure it matches the games they've played: don't want the testers using the resource to solve online maths puzzles, or doing fluid dynamics modelling!

Here's a flavour of the machines available - link.
