[slurm-users] RPC rate limiting for different users

Thanks for your swift response.

Ah yes, I had a look at the source code, and the only exception is root.  Doesn’t look like it would be too difficult to add the capability to have an exceptions table though which admins could configure?

We’ve enabled ratelimiting but it’s causing issues for some applications run by certain service account users.

It also seems that slurmrestd doesn’t cope well with it at all, we’ve been seeing lots of errors from that following enabling rate limiting.

The rate limiting is global for all users.  You can only play with the
various rl_* parameters described in the slurm.conf manual page to
increase bucket size etc. for everyone.
