OAR [wiki:handle_systemd_api_for_managing_oar_cgroups]

This is an old revision of the document!

Apparently there are some works in progress to change the CGROUPS API in the kernel.

Accordingly to

they want to allow only 1 process to become a CGROUPS manager.

So systemd is a good candidate. In this case we have to find a way to use the systemd CGROUPS API in OAR:

- /etc/oar/job_resource_manager_cgroups.pl - oarsh_shell

I have seen only a D-BUS API in systemd (no command line) and I didn't find the way to restrict the used cores (cpuset).
