For a OAR setup with different set of nodes (i.e. different homogeneous clusters) in the resources, you might want to give different priorities to nodes, so that some nodes are used in priority compared to others.

For that purpose, you can use the scheduler_priority property of the nodes (setting it using the oarnodesetting command), which will be taken into account as specified per the SCHEDULER_RESOURCE_ORDER configuration setting in oar.conf.
