Cutechess and Windows 11

[Rebel]

I noticed the following running Cutechess on Windows 11 -

1. It plays its games well, 50,000 in my case.
2. Memory keeps rising because of maintaining the PGN.
3. When the 50,000 games are finished cutechess exits normally....but... it does not free the memory it has used.

I don't have this behavior [3] on my 2 other Windows 10 machines, cutechess exists and releases the memory as it should and automatically starts the next 50,000 run.

I tried different Cutechess versions, it must be something weird of Windows 11.

Any one?

Is it Cutechess not freeing, or is it Windows 11 RAM cache?

It's not the cache, but the allocated ram cute-chess uses that Windows 11 is not freeing, while Windows 10 does, as it should. Example...

Code: Select all

ccc -concurrency 24 -tournament gauntlet -engine name=rebel-eas-one cmd=rebel-eas-one.exe proto=uci option.Hash=16 -engine name=rebel-eas-two cmd=rebel-eas-two.exe proto=uci option.Hash=16 -each restart=on tc=inf depth=9 timemargin=500 -draw movenumber=160 movecount=3 score=100 -resign movecount=3 score=999 -rounds 50000 -pgnout games-017-001.pgn -openings file=games.017.001.epd format=epd

ccc -concurrency 24 -tournament gauntlet -engine name=rebel-eas-one cmd=rebel-eas-one.exe proto=uci option.Hash=16 -engine name=rebel-eas-two cmd=rebel-eas-two.exe proto=uci option.Hash=16 -each restart=on tc=inf depth=9 timemargin=500 -draw movenumber=160 movecount=3 score=100 -resign movecount=3 score=999 -rounds 50000 -pgnout games-017-003.pgn -openings file=games.017.003.epd format=epd 

I have 20 of those in a batch file so in total it should produce 20 x 50000 = 1 million games.

After the first 50000 run W10 frees the memory (60% goes back to 17%) and starts the second one, and so on.

After the first 50000 run W11 does not free the memory, it start the second one with 60% and sooner or later RAM is 100% and the PC totally freezes.

Tried several memory cleaners, to no avail, only a reboot helps.

Obviously a W11 problem, could not find online help.

If the memory is not released after the first cutechess is closed it looks like some other issue like handles that are not properly closed.
You can check for that in process exlorer/task manager
But that should been a problem in w10 too.

Found it.....

Craziness an AMD driver can do that to a console application.

Apologies to Mr. Gates

Yep, had to download the latest version of Adrenalin as well.
