Hi Kamil,

I don't use QoS, so I don't have a direct answer to your question, however I use preemption for a queue/partition and that is extremely easy to set up and maintain. In case you plan with QoS won't work, you can set up a preemptable queue and force this user to submit only to this queue and that might be adequate for your needs.

Cheers,

Davide

Dear All,

I would like to be able to preempt (SUSPEND) a single QoS of a user
that blocks the queue for several days. Currently I have about
100 users on the cluster and it seems that setting the "Preempt"
option to each QoS (we have personal QoSes) is not optimal.

Is there a way to to set an option to this single problematic
QoS, saying that the QoS can be preempted by any other QoS?
It would be much more administrator-friendly solution ;)

Kind regards
