This example does not preclude other queues from accessing those nodes. One solution is to use some other generic attribute with all other nodes and queues.
TORQUE does not currently provide a simple mechanism for mapping queues to nodes. However, schedulers such as Moab and Maui can provide this functionality.
The simplest method is using default_resources.neednodes on an execution queue, setting it to a particular node attribute. Maui/Moab will use this information to ensure that jobs in that queue will be assigned nodes with that attribute. For example, suppose we have some nodes bought with money from the chemistry department, and some nodes paid by the biology department.
$TORQUE_HOME/server_priv/nodes:
node01 np=2 chem
node02 np=2 chem
node03 np=2 bio
node04 np=2 bio
qmgr:
set queue chem resources_default.neednodes=chem
set queue bio resources_default.neednodes=bio

More advanced configurations can be made with standing reservations and QoSs.
