Several hundred hosts, not a problem with SGE5.3 or SGE6.0, many users have
larger clusters.

For a hugh amount of jobs, you may need a 64-bit machine so that
qmaster/scheduler can allocate more than 2GB of memory.

And SGE doesn't use RSH to dispatch jobs to remote hosts, it is used when
there are interactive jobs. And you don't even need the normal RSH daemon
enabled on the hosts.


>Need some help understanding if SGE 60u3/u4 can meet my needs.  I have

>Too, since SGE uses RSH to dispatch jobs on remote hosts, is there an
