I tried it here with ChessGUI - and yes only uses 1 thread with amoeba-win64.exeGraham Banks wrote: ↑Fri Mar 13, 2020 10:28 pm
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.

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:

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)

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 Amoeba... - Too much hassle.Graham Banks wrote: ↑Fri Mar 13, 2020 10:28 pm Have you tried to run Amoeba 3.1 with 4 cores using ChessGUI, which is what I use for all of my testing?

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.

Graham, did you try what Ray suggests? ![Smile :)](./images/smilies/icon_smile.gif)

Re: CCRL 40/15 Testing Conditions (previously 40/40)
Where do I find the SF 10 benchmark you guys use to get an idea of what time control my PC would use?

Re: CCRL 40/15 Testing Conditions (previously 40/40)
Thanks! Is there a certain position that I analyze for the benchmark?

Re: CCRL 40/15 Testing Conditions (previously 40/40)
Hello, l am new there ![☺️](//cdn.jsdelivr.net/gh/twitter/twemoji@latest/assets/svg/263a.svg)
I would like to bench my little machine with ccrl standard but i don't know how to. Hope you can help me.
My machine is a Rasperry Pi 4 with Linux 64 bits OS.
Crafty bench is for Windows users. I read that is also a SF 10 bench ? but i did not manage to find the howto.
I have already SF 10 in my little machine and can force with Arena Gui to use only 1 core if necessary.
Thx

Re: CCRL 40/15 Testing Conditions (previously 40/40)
In Windows you just double-click the Stockfish 10 exe and type "bench", Adapted time control for 40/15 would be/:
T minutes for 40 moves where T = Your time / 2054 x 15 (for 40/15)
T minutes for 40 moves where T = Your time / 2054 x 15 (for 40/15)
Re: CCRL 40/15 Testing Conditions (previously 40/40)
Thanks ! The internal bench of SF I 1 core or multi-core?
Re: CCRL 40/15 Testing Conditions (previously 40/40)
Bench on 1 core. Just type bench, it will use the defaults. It is SF10 you should be using for that.
Re: CCRL 40/15 Testing Conditions (previously 40/40)
Hi
it is written
Our time control is equivalent to 40 moves in 15 minutes on an Intel i7 4770k at 3.5GHz.
We use Stockfish 10 as a benchmark to determine the equivalent time control for particular machine.
I would like to test my engine and i have a question :
how is the benchmark measured ?
What is the score with this benchmark on an Intel i7 4770k at 3.5GHz.
thx
excuse me my english is not very good

Scroll upwards and you'll find the answer.
Re: CCRL 40/15 Testing Conditions (previously 40/40)
With which version of Stockfish 10 do you run the bench?
x32 - x64 - or modern?

Re: CCRL 40/15 Testing Conditions (previously 40/40)
Is there a discussion somewhere about calibrating for lc0/gpu?

Re: CCRL 40/15 Testing Conditions (previously 40/40)
We don't currently calibrate for the GPU. Time control for games is simply set based on the CPU speed. That works so far because no two testers have had the same GPU. It would be a problem if two testers had the same GPU in machines with very different CPUs. I think CEGT put GPUs in their machines that are a sensible match for the CPU, and slow down the GPU via Afterburner or something so that the leela ratio on their machines is not vastly different.
There has been a lot of discussion in the CCRL member sub-forums in the past so I suggest you look there rather than carry on the discussion here.
Re: CCRL 40/15 Testing Conditions (previously 40/40)
Please excuse my ignorance, surely there is a very simple explanation for this that I don't know but I have been wondering for many weeks why there is no participation and no results from Stockfish 14 in the CCRL 40/15 list (as of today, just checked again http://ccrl.chessdom.com/ccrl/4040/), why is the list so lagging behind?
