I believe the method James describes only allows that one qos to be used by jobs on the partition, it does not set up a Partition QOS as Paul is looking for.
Create the QOS as James describes, but instead of AllowQOS use the QOS option as Danny eluded to, and as documented here http://slurm.schedmd.com/slurm.conf.html#OPT_QOS. 


PartitionName=batch Nodes=compute[01-05] *QOS*=vip Default=NO 
MaxTime=UNLIMITED State=UP



This will allow for a partition QOS that isn't associated with the job 
as talked about in the SLUG15 presentation 
http://slurm.schedmd.com/SLUG15/Partition_QOS.pdf

Thanks for the insight.  I will try it out on my end.

Thanks a lot, James. Helped a bunch ;-)

I was able to do this on slurm 15.08.3 on a test environment. Here 
are my notes:


- create qos


sacctmgr add qos Name=vip MaxJobsPerUser=5 MaxSubmitJobsPerUser=5 
MaxTRESPerUser=cpu=128


- create partition in slurm.conf


PartitionName=batch Nodes=compute[01-05] AllowQOS=vip Default=NO 
MaxTime=UNLIMITED State=UP



I believe the keyword here is to specify the QoS name when creating 
the partition, for my case, I used AllowQOS=vip

    I'm guessing you also added the qos to your partition line in
    your slurm.conf as well.

        I did that but it didn't pick it up.  I must need to
        reconfigure again after I made the qos.  I will have to try
        it again.  Let you know how it goes.

            Hi Paul,

            I did this by creating the qos, e.g. sacctmgr create qos
            part_whatever

            Then in slurm.conf setting qos=part_whatever in the
            "whatever" partition definition.

            scontrol reconfigure

            finally, set the limits on the qos:

            sacctmgr modify qos set MaxJobsPerUser=5 where
            name=part_whatever

            ...

                In 15.08 you are able to set QoS limits directly on a

                partition. So how do you actually accomplish this? 
                I've tried a couple of ways, but no luck.  I haven't

                seen a demo of how to do this anywhere either.  My
                goal is to set up a partition with the following QoS
                parameters:

                MaxJobsPerUser=5
                MaxSubmitJobsPerUser=5
                MaxCPUsPerUser=128

                Thanks for the info.
