[slurm-users] Working with local licenses

[Tager, Alexey]

Hi Ahmet,

We tried remote licenses, but encountered following issues, which lead us to using of local licenses.
- only low case while inserting by sacctmgr
 - dead locks and duplicate records
- direct insert is working and case sensitive, but scontrol doesn't see change until slurmctld restart


Regards
Alexey

Hi;

You don't need to modify slurm.conf and reconfigure. There is a remote/dynamic licenses feature:

https://slurm.schedmd.com/licenses.html

You can add licenses using scontrol command such as:

sacctmgr add resource name=matlab count=50 server=rlm_host \
   servertype=rlm type=license

Regards;

Ahmet M.
