[slurm-users] [ext] REST-based CLI tools out there somewhere?

[Hagdorn, Magnus Karl Moritz]

Hi Chip,
what are the security concerns? Being able to control jobs is one
thing. Your users still need to setup the jobs which presumably
involves moving data. We have provided some launchers written in python
for specific use cases (that don't involve moving data). We also have a
jupyterhub that launches notebooks on the cluster. This works quite
well, but you do end up with interactive jobs which are most likely
less efficient than batch jobs. Again, this really depends on your use
cases.
Regards
magnus
