CCRL Discussion Board

The reason is that only one tester has the RTX2080, and that sits in a 4 core machine. So it has been impossible. However I understand that tester is putting together a new machine that will have at least 8 cores, so I think this will happen in the next few weeks.

A 3,000 Elo engine created in just two months, that is impressive !

That is going to be a lot of work, but if you manage to do it I'll be very interested to see it.

Let me know once you have downloaded it and I will remove it.

That is very cool !

40/15 ?

No they are not available from the website, 99.99% of people would not be interested. However they could be supplied on request. There are two options: - 5000+ text files which are daily ratings lists from 2006 to now containing all engines or - files for each individual engine showing daily ratings...

Or for example, here is the ratings list from 2007-03-02 Rybka 2.2 64-bit 4CPU => 2988 211 Rybka 2.1 64-bit 4CPU => 2971 179 Zap!Chess Zanzibar 64-bit 4CPU => 2937 310 Rybka 2.2 64-bit => 2918 191 Rybka 2.2 32-bit => 2893 822 Rybka 1.2 64-bit => 2893 771 Rybka 1.1 64-bit => 2884 545 Rybka 1.2 32-bit...

Here is the daily history of Stockfish 10 for example for 4015: 2018-11-30 3413 (+128 -128) 15 2018-12-01 3361 ( +34 -34) 273 2018-12-02 3384 ( +24 -24) 607 2018-12-03 3381 ( +22 -22) 738 2018-12-04 3381 ( +22 -22) 771 2018-12-05 3385 ( +20 -20) 853 2018-12-06 3387 ( +19 -19) 1090 2018-12-07 3387 ( ...

The processing scripts actually calculate the rating by day. They need to do that for the graphs that you see for each engine. I'm sure you've seen those - click on an engine and scroll down.

Yes but Graham is using a CPU.

What is best on a pair of RTX2080 GPUs is very different to what is best on a CPU.

What is the .cmp file ?

Yes, close the GUI, re-start it and edit the engine and re-save the parameters seems to work. If not, manually edit the GUI engine config file.

However I edited the engine parameters again and saved them down, that config file has corrected itself, and now it is using 4 threads. You could also manually edit that file (but best not to call up the UCI parameters via the GUI after that).

On my Octal: (50% is 4 of 8 threads)
.
.

It seems to be a ChessGUI bug though. ChessGUI sends the threds=1 command to the engine, and this is why:

The config file says this:

[Amoeba 3.1 64-bit 4CPU]
Affinity=0:0
Hash=512
Threads=1
MultiPV=1
Log=false
UCI_AnalyseMode=false

Even though the UCI paremeters popup is this:

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.

I tried it here with ChessGUI - and yes only uses 1 thread with amoeba-win64.exe

I can't get Amoeba to use more than 1 core on my non-popcount octal (2x4CPU Xeon).

That may be a ChessGUI problem ? I saw another bug report about that.

https://github.com/abulmo/amoeba/issues

I may not be understanding correctly, but if the engine exe or supporting files contain hundreds of positions with pre-programmed moves for those positions, where the engine moves instantly, then it doesn't meet our rules for testing. Additional clarification is needed. If it is another NN engine li...

New users have to have their first couple of posts approved, and they have to be in the Public forum first it seems. After that it should be fine. That is what we've experienced in the past.

It means "Likelihood of Superiority" and is calculated by bayeselo.

Games by month downloads are now available on the 404 list.

There is an option in our scripts to offer downloads by month. We haven't used it for a long time. You can't use it to incrementally update a previous download of our database and that is where people got confused before. Sometimes engines are re-named, sometimes they are killed, and sometimes they ...

Do you want the actual games or just the ratings lists ? If just snapshots of the lists themselves, how many do you need or what dates ? For example see attached
