[slurm-users] Restrictions for new/inefficient users?

We have the problem that increasing numbers of new users have little to
no idea about the amount of resources their programs can use
efficiently.  Thus, they will often just request 32 cores, because
that's what most of our nodes have, and 128 or 256 GB, for reasons which
are unclear to me, even though the majority of our nodes don't have that
much RAM.

I know that Ole's slurmaccounts has a NEWUSER flag which allows
resources to be restricted for uses for a certain period of time.  I
worry that in our case some users work quite sporadically and don't
acquire experience very quickly, so that lifting the restrictions
after a fixed time might not be that useful.

Another approach might be to trigger an EXPERT flag if some appropriate
combination of percentage efficiency and absolute resource usage is

Has any one tried anything like this or some other approach?
