[torqueusers] Re: Associating a queue with specific nodes

Hello everyone,
If you have associated a queue to specific nodes in the "nodes" file  then you
should be able to use them specifically as well. However, it is not enough to
use the "#PBS -q name_of_the_queue" because this will only take the
characteristics of the queue (runtime, disk,mem, etc). However if you define
"#PBS -l nodes=name_of_the_queue" the destination nodes will be forced to thos
e assoaciated to this queue in the nodes file.
I am not sure about a default definition for each queue about which nodes
using. I am not taling about the nodes file, wheren the queue defined for each
node is another attribute for that node. I am talking about a definition
within the queue attributes.
Hope it helps
Marc
