3.2 Nodes Properties
TORQUE can associate properties with nodes to aid in identifying groups of nodes. It's typical for a site to conglomerate a heterogeneous sets of resources. To identify the different sets, properties can be given to each node in a set. For example, a group of nodes that have a higher speed network connection could have the property "ib". TORQUE can set, update or remove properties either dynamically with qmgr or by manually editing the nodes file.3.2.1 Run-Time Node Changes
TORQUE can dynamically change the properties of a node with the qmgr command. For example, to give node001 the properties of bigmem and dualcore:To relinquish a stated property, use the "-=" operator.
3.2.2 Manual Node Changes
The properties of each node are enumerated in $TORQUEHOME/server_priv/nodes. The feature(s) must be in a space delimited list after the node name. For example, to give node001 the properties of bigmem and dualcore and node002 the properties of bigmem and matlab, edit the nodes file to contain:
For changes to the nodes file to be activated, pbs_server must be restarted.
