batch queuing systems with a sequential job queue and a parallel job
queue ? Do I misunderstand the question ?
If you want to know wether your beowulf can be divided in separate
beowulf cluster through Mosix, the answer is yes : you only have to put
a different description in /etc/mosix.map and restart the mosix daemons.
You can also request a particular job to stay on a specific node,
disabling Mosix load balancing policy for this job.

At first sight, I would say a queing system (like PBS or others) would
suit your needs, since Mosix is not (yet) available on Alpha processors
Linux systems.

Hope it helps,
