Yes, and yes.

The Basic Edition releases do not include a scheduler.
The professional editions includes several queuing and job assignment
tools.

You can use most schedulers with Scyld Beowulf.  There is a version of
PBS Pro available, and installations have used OpenPBS, LSF and SGE.
In most cases it's best to treat the cluster as a single machine, and
have the scheduling daemon run only on the master.

The scheduling/queuing tools included in the professional edition are
oriented to simplicity of use on a single cluster that is dedicated to a
small number of users and applications.  Most commercial schedulers use
sophisticated rules of who and what type of programs can use multiple
systems across a site, necessarily leading to much more complexity in
configuration and use.
