[slurm-users] Submitting jobs via SystemD

[Ondrej Valousek]

Hi list,
I am wondering if there is a plugin allowing to submit jobs via SystemD
(I.e. using systemd-run) on exec nodes.

I have actually modified SGE sources to offer this option (available at
https://github.com/daimh/sge) and it works quite well.

The advantages are:
- we let systemd to track and manage job (jobs are started as services) so
do not have to do it ourselves.
- we use systemd to get job stats (cpu/mem usage etc)
- we let systemd to manage cgroups for us (which means cgroups v2 can be
nicely supported this way)

Disadvantages:
- it expects SystemD (I.e. Linux only) is installed on all exec clients
- minimal version we can live with is SystemD 230, for best results 240 or
newer.

Anyone interested?
Cheers,
Ondrej
