[slurm-users] Is that possible to submit jobs to a Slurm cluster right from a developer's PC

[Ryan Cox]

Be careful with this approach.  You also need the same munge key 
installed everywhere.  If the developers have root on their own system, 
they can submit jobs and run Slurm commands as any user.

ssh sounds significantly safer.  A quick and easy way to make sure that 
users don't abuse the system is to set limits using pam_limits.so, 
usually in /etc/security/limits.conf.  A cputime limit of one minute 
should prevent users from running their work there.  If I'm reading it 
right, it sounds like you do want jobs running on that system but do not 
want people launching work over ssh.  In that case, you would need to 
make sure that pam_limits.so is enabled for ssh but not Slurm.
