[slurm-users] Adding Users to Slurm's Database

[Paul Edmon]

We manage this via our job_submit.lua script.  At submission time the 
script looks to see if they already have an account or not and if they 
don't it adds them.  To lower impact on the database we have it cache 
the lookups.

I think the real concern is continually beating on the database. So you 
want to cut that down by whatever means you think is reasonable.
