The following describes how I currently have the machine:

	# cpuset -r -s /		# Show the cpusets from root down.
	/
	/batch
	/boot
	# cpuset -d /		# Show the script to make root.
	cpu_exclusive
	mem_exclusive
	cpus 0-63
	mems 0-31
	# cpuset -d /boot		# Interactive work and daemons in here
	cpus 2-9
	mems 1-31
	# cpuset -d /batch
	cpu_exclusive		# The cpus cannot be shared.
	cpus 10-63
	mems 1-31

The root cpuset is the default.  The boot cpuset is created during boot as per the documentation.  The batch cpuset is created by the enclosed file which is kept in /etc/init.d.  Please note that this is a work in progress, if you use or copy any part of it, it is AT YOUR OWN RISK.  The three suse.pbs_??? scripts are the ones out of the torque distribution, with minor changes to make them run on my machine.  I'm currently rewriting four scripts to be more robust and LSB compliant.

You can check that all is well by cat'ing /dev/cpuset/batch/tasks, you should see the PIDs of mom, sched and server listed there.
