Dependencies for IRIX 6.5
-------------------------

Array Session Handles:

	If executing with root permission Grid Engine will set a unique array
	session handle (see array_sessions(5)) for each job. This array
	session handle will stick to every process of the job and cannot be
	changed by the unprivileged user. The array session handle will also
	be stored in the accounting information which can be traced with
	satd(1).

Processor Sets:

	Processor sets as available for IRIX 6.2 and earlier are no longer
	supported. IRIX provides the Miser facility with the miser_cpuset(1)
	command. It is possible to interface miser_cpuset(1) from Grid
	Engine.

Checkpointing:

	The IRIX CheckPoint and Restart (CPR) facility is supported (see
	cpr(1)). Please use the checkpointing interface specification "cpr"
	in the checkpointing objects which you define for IRIX 6.5 machines.
