Re: master node not in qstat

I have not tried the new SC 0.93.2 SGE plugin yet but you should be
able to use MASTER_INSTANCE_TYPE to define a special instance type for
the master.

BTW, why is Star Cluster changed SGE as a plugin in a bugfix release
(0.93.2) and not officially relasing a proper feature release?
