sge in rocks cluster 4.1

even through current setup of sge in rocks seem to work I have some observations/suggestion on sge in rocks,
  • understood the non mounting of $SGE_ROOT/default, rocks make copy of the $SGE_ROOT/default to each node. This approach does not allow the shadow master to support the qmaster.
  • the rocks' internal DNS domainanme is "local" and should be used e.g. the default domain should be : local and not none. Right now in the configuration the default domain is set to none
  • act_qmaster should be the hostname of 10.1.1.1 e.g. .local instead of the frontend.outsidedomainname. Since the rocks cluster use a private network and private domainanme, there is not need to using any external public name for sge. e.g. the /etc/hosts of the compute nodes doesn't require any external hostname of the frontend
  • since the frontend has dual NIC (at least), one want to set host_aliases (frontend.local frontend.outsidedomainname) http://gridengine.sunsource.net/howto/multi_intrfcs.html
