A beowulf cluster can have a batch system on it, so in that way there is
no difference.

A cluster of client workstations, using the clients idle cycles, works
great until your thesis / CFO's budget / experimental results get
destroyed by an errant batch process. If you have no clients on these
workstations then you are back to a cluster again.

That's just my opinion, I could be wrong.
