Question regarding CLOP and cutechess-cli

I've started using CLOP (windows version) and must thank Remi for a very nice program. But I have some problems when I'm using CLOP together with cutechess-cli. In the .clop file I ask for 9 threads and this works fine, but after a while one after one of the threads dies so after a couple of hours I have only one or two threads still alive. When I check my task manager I still have 9 instances of cutechess-cli, but only one or two instances of the engines.

I don't think the engines crash, because when running with the same timelimits (40/10s) and same number of threads with littleblitzer I don't get any crashes and no loss on time.

I've been working two weeks with different settings, different time limit, different eninges and different number of threads, but I can't get rid of the problem. Has anybody else had this problem and does anyone have a suggestion for a solution.

Regards
Jacob

Not sure what is happening - is there anything in the log files?

Also

cutechess-cli is a different environment so you may get different behavior there. Maybe you should try the -recover option to cutechess-cli. Without this it will terminate a match if one of the engines appears to not be responding.

Hi, thanks for your answer.

The log file shows nothing, so no help there :-(

I allready use the -recover option, the -restart option for both the engines and -wait 100. I havn't been using any draw option yet, but I'm trying this now to see if this might help.

Without solving this problem I don't get enougth games to use CLOP, and that's a shame since I really like CLOP.

Thanks anyhow for answering my question.

Best regards Jacob

I've run 10's of thousands of games with CLOP + cutechess-cli, no problems (although I have had to weed out some engine opponents that were not stable).

One difference is, I don't use Windows - all my test machines are Linux.

What version of cutechess-cli you are using? I use 0.5.1 and it is fine.

Thanks for your answer.

I'm using version 0.6.0.

After I added -draw movenumber=120 -movecount=10 score=30 it works better, still a few lost threads, but now I usually have around 7 of 9 threads after running it through the night. So it looks like the engines call it a draw and quits while cutechess still is playing on. If I change my -draw a bit more it might work even better.

Do not use that version. See some issues here when using windows.

Thanks for the tip, I'll install version 0.5.1 and see if that works better.
