Yes, it's a line like:

AllowGroups root operator

on the nodes and put the admin staff in this additional group.

MPICH2 since 1.3 has a tight integration into SGE by default. For Gaussian it's 
necessary to adjust Linda_rsh to call a plain rsh instead of /usr/bin/rsh, so 
that the rsh-wrapper will catch it and route it to SGE's qrsh (in case you use 
Linda).
