[Beowulf] Experience of using multiple network devices on a node in cluster

[Tajendra Singh]

Greetings!!

Many of the vendors are providing two GigE ports by default on systems which
are being used as nodes in beowulf types of clusters.

Is there anybody who tried connecting both the ports to the switch? I know
LA-MPI ( http://public.lanl.gov/lampi/) talks about utilizing multiple
network devices in real time, but did not get chance to experiment with it.
I would like to hear your opinion whether it makes sense, looking at the
lower costs per port for GigE switches?

Thanks in advance,
