5.700 Mapping a Queue to Subset of Resources

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

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.

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