Are you aware of any ongoing efforts to port jobstats to PBSPro

[CanWood]

Hi folks,

I recognize this project is slurm specific and it would be quite a task to overhaul it for PBSPro. Just curious to know if anyone on your team has explored it, or if you're aware of any active forks pursuing a PBSPro port?

Cheers

Hello,

this is the first such request. I am not familiar with PBSPro but if I google it I see that it can use cgroups. Do you know how it does that and if it organizes cgroups similar to what slurm does (i.e. by job and maybe user/step)? E.g. slurm does this for memory cgroup (similar for cpu, if configured to use cgroups for accounting):

/sys/fs/cgroup/memory/slurm/uid_331949/job_1859370/step_0/task_7
/sys/fs/cgroup/memory/slurm/uid_331949/job_1859370/step_0/task_7/cgroup.procs
/sys/fs/cgroup/memory/slurm/uid_331949/job_1859370/step_0/task_7/memory.use_hierarchy
....

and that file path is what we use to parse out jobid of that particular job (and uid, but that's less important) + stats are available in that directory.

I currently work at a site that uses PBS Pro with cgroups. When I get a chance, I'll take a look at this and see if I can contribute anything.

Thanks @plazonic and @pbisbal1. Under PBS, the cgroup hierarchy is as follows:

/sys/fs/cgroup/devices/pbspro.service/jobid/27138999.servername
/sys/fs/cgroup/cpuset/pbspro.service/jobid/27138999.servername
/sys/fs/cgroup/memory/pbspro.service/jobid/27138999.servername
/sys/fs/cgroup/cpu,cpuacct/pbspro.service/jobid/27138999.servername
/sys/fs/cgroup/systemd/pbspro.service/jobid/27138999.servername

and under those, just like what in in @plazonic 's post, so the contents of the memory are what you've posted. So no breakdown by uid, step, or task.

Cheers
