If you specify "-exclusive" it will be "exclusive" - it's per job not to allow
any other job on this machine/queue (resp. "these machines" in case of a PE
request requiring several nodes). It's not per user.
If you want to reserve a node for your own use only, you can make an advance
reservation first, and then submit into this advance reservation:
$ qrsub -pe smp 24 -l exclusive -d 3600
Your advance reservation 196 has been granted
$ qrstat
ar-id name owner state start at end at
duration
------------------------------------------------------------------------------------------
196 reuti r 03/15/2013 16:06:37 03/15/2013 17:06:37
01:00:00
$ qsub -ar 196 -pe smp 12 foobar.sh
Your job 5814 ("foobar.sh") has been submitted
$ qsub -ar 196 -pe smp 12 foobar.sh
Your job 5815 ("foobar.sh") has been submitted
resp.
$ qmake -ar 196 -pe smp 12 --
(It's even not necessary to specify "-l exclusive" for the advance reservation:
in case you request 24 cores with "allocation_rule $pe_slots" in a node with 24
cores the advance reservation will block them already.)
