[GE users] PE queue_list for 6.0

Hi Barry,

You can use hostgroups for this.  In "all.q", you can define PE lists on
a per-hostgroup level.  EG, the entry would be something like:

pe_list     NONE,[switchAgroup=mpiA,switchBgroup=mpiB]

where switchAgroup and switchBgroup are GE hostgroups defined
accordingly.  Please read man pages and documentation regarding cluster
queues and hostgroups for more details.

Regards,
	Charu
