There are some users (listed in /etc/passwd) who can use Slurm to submit jobs in our cluster. But, with sacctmgr we can also define users belonging to some account(s).

What should be the connection of these two group of users?

Thanks.

Slurm uses its own user accounting system in order to achieve a clear management of the resources of the cluster. This means you can do things like prevent users for running jobs in other accounts (using associations), limit the number of jobs, apply QOS, etc. If the user is not defined in the Slurm accounting system you are not taking advantage of those features of Slurm. Check the man for more information.

It mostly depends in the policies and management that you want to have in the cluster. It is not mandatory to run Slurm using the database (e.g It can use a plain text file) but it will limit the possibilities that you have to manage your resources. I would recommend to map all the users in your system (the list of /etc/passwd) to the Slurm data base, in case you want to have any special behavior/constrain over your users in the future.
