cutechess-cli 0.6.0 silent mode?

I was wondering if there's a way to run this program, without getting any update on progress.

May be redirecting the output to a file?

cutechess ... >file.txt

Do you think that would reduce the overhead? I'm getting around 3% CPU usage from the exe, I'm guessing a part of it, is because of the constant updating of the Command Prompt window.

I suppose it will be similar. In my tests, I use all the available cores minus one, to let the system and cutechess use all what they want.

Is that overhead normal, in your experience? You probably didn't even notice, if you free up a whole core for "secondary" tasks. I can imagine how this would be the case.

I'm just observing now a current running test in an AMD with 8 core, and cutechess uses 1-2%, mostly 1%. Its output it’s going to the screen. Of course this % depends mainly of the speed of the cpu.

I free a whole cpu to obtain more stable results. Windows in particular uses often part of the cpu for who knows what. Many testers do the same.

May be if you have only 2-4 cpu you can test using all of them. The greater number of games will be more important in this case.

Considering the impact of hyper threading on overall CPU speed, your numbers are very similar. Still, I would hope that giving up a GUI, would bring CPU utilizations down to the tenths of a point.

One way is to redirect it to null device, you can use, from batch file for example.
cutechess ... > NUL

I'm going to try that, thx.

PS: the PGN looks ok, but I got the message
"warning: engineprocess: pipe reader was terminated"
Any reason for concern?
