hello all,

    Is there a way to run prolog or some kind of script under root 
privileges in parallel kind of job? What i have observed is that prolog 
script runs on master node and not on slaves.
Actually i want to disable user login directly onto compute nodes, and 
only make it possible via SGE. Since prolog script runs under root 
privileges, i can change say /etc/security/limits.conf for the time job 
is being run and hence can restrict normal SSH(without SGE).

Can i run prolog on slaves or is there any other way to restrict normal 
user login?
