I think this question is of broader audience on the beowulf.org
mailing list, but anyway: what are you using in the cluster besides
OpenMPI? Although I'm biased, I would suggest SGE GridEngine, as it
supports more parallel libs than Torque by its qrsh replacement; e.g.
Linda or PVM. Also the integration between the qmaster and scheduler
is tighter. In Torque you have two commands: "qstat" and "showq". The
former is the view of the cluster by Torque, the latter the one of
the Maui scheduler - and sometimes I observe that they disagree about
what's running in the cluster and what not (we use SGE, but we have
access to some clusters in other locations which prefer Torque).

The support for SGE will be in OpenMPI in1.2 AFAIK.

Question: you have a central filer server in the cluster, to serve
the home directory to the nodes and which could also act as a NIS,
NTP and SGE qmaster server? You mentioned only the nodes.
