[slurm-users] Fair share per partition

Hi all,

Clusters sometimes have a couple of different types of hardware, e.g. lots 
of standard plus small amounts of highmem - with a partition per type.

Sometimes one partition, e.g. "standard", is much busier than e.g. 

In a fair share set up with multiple accounts and multiple users per 
account, a single user making heavy use of an otherwise idle partition can 
negatively effect their account's priority on the busy partition.

So having fair share per partition can be useful.

I imagine I can handle this by, for each group of users I'd normally 
create a single account for, creating a duplicate "highmem" account. I 
could then use a job_submit script to change the job's account to its 
buddy "highmem" account when it sees jobs submitted to the himem 

But this is a bit of a faff for reporting and managing users, particularly 
as I've not figured out how to define a group of users in one place (say, 
a unix group) that I can then use multiple times.

Is there a better way, please?
