Rocks is very easy to use. I found it a bit easier to set up than
OSCAR, but I think OSCAR has some other advantages (e.g., it can be in
can be installed on several distributions). Both Rocks and OSCAR are
great ways to build first generation beowulf clusters, and I hear
Mandrake's is nice too.
However, I believe all of these use NFS for at least /home. This may
not affect you much on a small clusters, but it depends on your
application. I avoid using NFS whenever I can. When/if you encounter
bottlenecks with NFS, you should consider looking at lustre
(www.lustre.org), PVFS (www.parl.clemson.edu/pvfs/), and v9fs
In addition to using NFS, these first generation cluster environments
use ssh or rsh to start processes on the compute nodes. These work
okay, but bproc (bproc.sf.net) provides a better way IMO.
