Warning: Duplicate cpuset controllers detected about beast2

[rbouckaert]

The difference between the v2.6 and v2.7 beast script is that it calls uname -m to determine the CPU type and it is using a different java version.
Can you run that command on its own and see whether it produces the same warning?

NixOS/nixpkgs#163164 suggests it may have something to do with java: can you try java -version and /path/to/beast/jre/bin/java -version (replace /path/to to where beast is installed) as well?

uname -m returns x86_64.

My Java, java -version returns:

openjdk version "11.0.9.1-internal" 2020-11-04
OpenJDK Runtime Environment (build 11.0.9.1-internal+0-adhoc..src)
OpenJDK 64-Bit Server VM (build 11.0.9.1-internal+0-adhoc..src, mixed mode)

The Java come with BEAST 2.7 returns:

[0.002s][warning][os,container] Duplicate cpuset controllers detected. Picking /sys/fs/cgroup/cpuset, skipping /dev/cpuset.
openjdk version "17.0.3" 2022-04-19 LTS

Thanks! So, it looks like it is the java implementation included with BEAST v2.7 that is causing the error message.
If beast still starts after producing this warning, I think it should be OK. From what I understand, adding -Xlog:disable as java directive suppresses this warning.

I would appreciate if you can confirm that beast runs as before and
/path/to/beast/jre/bin/java -Xlog:disable -version
suppresses the warning, I can update the beast script.

Yes, it seems to be working. I have launched about fifty analyses, and they look normal for a while. The argument -Xlog:disable indeed suppresses the warning.

But, I am unsure if it should be suppressed in the script. Since the problem is not one excessive line of warnings but the question: does it influence the results, especially when multithreading is turned on?

[rbouckaert]

Thanks for the confirmation. From what I can find out, it seems to be a configuration issue with the system that runs java (making multiple cpusets available), which is annoying when processing the output but seems harmless otherwise. Can you perhaps ask the system administrator of the cluster to have a look into this?

Thank you very much for your help!
