Exclude certain nodes when submitting jobs with qsub / torque?

Question

When submitting batch jobs with qsub, is there a way to exclude a certain node (by hostname)?

Something like

# this is just a pseudo command:
qsub myscript.sh --exclude computer01

Answer 1

Depending on how many nodes you would like available, there are a couple of options.

You could specify by name a specific node that is acceptable:

qsub -l nodes=n006+n007

To exclude, say, one node out of a group, I would ask the administrator to assign a dummy property to all nodes but the one you want excluded. Then you can request for that property.
