Hi all,

In a cluster with 15 computers, I would like 3 always free for the
running of short jobs. 

behaviour wanted:
1) if 12 nodes were being used by 6 short jobs and 6 long jobs, and a
long job was submitted, it would just wait in the queue.
2) if 12 nodes were being used by 6 short jobs and 6 long jobs, and a
short job was submitted, it would run and there would be 2 nodes free,
but once one of the 6 long jobs ended, the number of free nodes goes
back to 3.

I have been trying to do this with standing reservations, to no avail..
Does anyone know if this is possible / how?

Thank you

Chiao
