Number of Cpu's does not work on slurm

Trying to use this in a slurm cluster, I always get 1 processor allocated no matter what i put in the req_nprocs configuration setting.

It seems that the corresponding option is not included in the slurm script template. I tried to edit it, to no avail.

Since I don’t have access to every possible batch system, the choices made in the default batch script templates generally reflect the needs of whomever contributed the script for that job manager. If there’s a reason for omitting req_nprocs in the Slurm script, I don’t know what it was.

To the larger point, one of the TODOs after we finalize this release is to revisit the templating system, since the inability to selectively include lines is a clear weakness of the current scheme.

Is there a reason to not have it? If not, I will add it.

Though, right now default is ‘’, which could be interperted differently from 1 on some platforms (slurm defaults to 1): there’s no way to leave it missing. Since jupyterhub depends on jinja2, the batch scripts could be made to use this as well. Do you have any opinions on the matter?
