Hello everyone!
Hello,
I think this question is of broader audience on the beowulf.org
mailing list, but anyway: what are you using in the cluster besides
Yes, I think you are right, but we are going to use OpenMPI and we wanted
to hear and your opinion (OpenMPI experts opinion) :)
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
At this moment we use MPI and PVM but we would like to test and use other
technologies, projects, ideas as well. I think that SGE GridEngine is a
very good project and maybe that is our final choise!
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.
Yes, at this time we think to use an additional node as the master node
with a better HDD for these jobs

Thank you for your help and your time :)

Thanks very much for your time and I am sure that your opinion will be
of of great help to us!
