I want to free nodes from jobs, when high priority job submitted.

I have 3 queues. I want:
all.q lowest priority
mid.q middle
hig.q highest
Still the question: which effect to you want to achieve by this? Should jobs 
start earlier in hig.q - should jobs get more CPU cycles - should jobs get 
suspended in all.q?

I can solve this problem only with subordinate list?
qconf -sq hig.q
subordinate_list  all.q=1, mid.q=1
qconf -sq mid.q
subordinate_list  all.q=1

I need to setup high and low priority queues for the same nodes.
I preferred to make it without subordinate lists.
I know, that the following parameters are dealing with this:
seq_no                10
The seq_no is used to determine which queue  a job will run in.

priority              20
If I'm right please explain me the meaning of numbers,
Whether you are right depends on what you mean by high and low
priority queues.

This is the nice value.  What this means in practice is that if there
are more processes/threads running on the node than there are
cores/threads to service them then the jobs with the lower nice value
will get more of the available CPUtime.




if no correct me.
