CCRL Discussion Board

Glad to see that, Graham! Thanks!

https://github.com/abulmo/amoeba/releases/tag/v3.2 Amoeba version 3.2 Some code enhancements and simplifications. Amoeba-3.2 is about 30 elo stronger than amoeba 3.1 in selfplay. Amoeba-3.2 comes with some tools: - a SPRT tourney manager - a postmortem reverse game analyser - NEW an epd file tester:...

Graham, did you try what Ray suggests?

Have you tried to run Amoeba 3.1 with 4 cores using ChessGUI, which is what I use for all of my testing? You set threads to 4, but it still only uses 1. ChessGUI is a Windows application. I would have to either try to install it on my Linux workstation using Wine, and also use Windows build of Amoe...

Amoeba, like for an example Stockfish, supports the "Threads" option. So if Stockfish works in your application, Amoeba should certainly work too. Amoeba: uci id name Amoeba 3.1.l64p-l id author Richard Delorme option name Ponder type check default false option name Hash type spin default ...

Could you then also add Amoeba 3.1 4CPU to the 40/40 list please?

I was wondering how new engines obtain their initial grade? Could someone please explain the process?

Still can't make it work... I give up.

Thanks Richard - I did not know it uses UDP... I still can't connect via Livius anyway... Will look further.

Hey Richard - glad to see you here! :) Look, could you please do a telnet GrahamCCRL.dyndns.org 16001 and tell me whether it gives any output? When I execute it all I get is: dejan@turing$ telnet GrahamCCRL.dyndns.org 16001 Trying 222.154.252.101... After some time the connection times out. I also u...

Could anyone here who uses Linux build of Livius confirm being able to connect to the GrahamCCRL.dyndns.org ? I have tried 50 times to connect to this server in the last few months, and it failed every time (I double-checked the connection parameters - I am perfectly aware of the fact that port chan...

Why Amoeba 2.8 when you have Amoeba 3.0 ?

Graham, I assume someone has already added the Amoeba 3.0 64bit 4CPU to the 40/40 ?

I recommend installing MSYS2 ( https://www.msys2.org/ ) which brings POSIX environment to Windows with BASH, 32bit and 64bit toolchain (MinGW 32 and 64).

Preferably played by an engine I am interested in. Also would be nice to see the list of games currently being played...

It would also be nice to add Amoeba 3.0 (single thread and 4-thread) to the 404 section as well...

If the Windows executable runs on Wine (it should in most cases), I recommend testing inside a container (Docker or LXC). That way the testing environment will not be affected if the executable contains a virus.

Lc0 is already on CCRL, but not in all sections - check the 404 section here: http://ccrl.chessdom.com/ccrl/404/rating_list_all.html

I wonder is there a plan to add 4CPU version of Amoeba 3.0 64bit to the competition as beginning with version 3.0 Amoeba can utilise multiple cores?

I would also like to thank Richard Delorme for this wonderful, open-source chess engine!
