<div class="PlainText">Hi Brian,<br>
<br>
QOS is probably the right way to go. You can set up a QOS 'vip', which<br>
can preempt other QOS. We don't preempt, but use multifactor priority<br>
with various QOS with different priority values. In that case, VIP jobs<br>
won't start immediately, but just get pushed to the front of the queue.<br>
On the other hand, no CPU-time is lost due to low-status jobs being<br>
terminated early due to preemption (although if the low-status jobs are<br>
able to do some form of checkpointing that will be less of an issue).<br>
Depending on how pushy your VIPs are, they might go for a preemptionless<br>
solution, too.<br>
<br>
Cheers,<br>
