Node and Job Attributes

You can further refine exactly which nodes you want your job to run on by specifying node attributes. the pbsnodes -a command (see below) can help you see which attributes are defined for nodes. The table below illustrates some kinds of node properties you can choose from.

Network	CPU Type	CPU MHz	Memory	SMP status
gigabit	athlon	p1800	m1500	dual
	p3	p500	m256
	xeon	p2000	m1000
	opteron	p1400

By using these node attributes, you can, for example, request that your job only be scheduled on a node that has an 'athlon' processor, and gigabit ethernet.

Node attributes are passed to PBS on a -l line:
#PBS -l nodes=1:athlon:gigabit

Or, if you need a dual processor system and 2 GB of RAM:
#PBS -l nodes=2:dual:m2048
