And that are the reasons why SDM has been introduced. With SDM no changes on the 
user interface of your clusters are necessary. Users of cluster A can have a 
completely different setup as users of cluster b.

When SDM assigns a host to a SGE cluster it executes a script on the host. Per 
default only the SGE execd is installed. However it can also reconfigure your 
user database (different NIS server) or (un)mount file systems.

It sucks if administrator must do it manually, SDM automates these tasks.
