If you're concerned about over-subscription of the node's CPU by jobs in both queues, you may want to set the node's slots complex value to: slots=1 (if you have a single-core CPU) or slots=2 (dual-core CPU). Then only 1 (or 2) job(s) will run on the node at a time. 

qconf -mattr exechost complex_values slots=1 n02
