I suppose there is nothing to prevent you from using dual network
cards and dual switches, so that each machine has two distinct links
to the rest. Beowolf ought to not mind this since it wouldn't know
that the two NICs are on different switches...
But when a _computer_ dies, thats another issue, and on a cluster, I'd
think the probability of a computer going down is far higher than the
network, since the switch should be more reliable than the computers
themselves (no disks to blow out bearings, etc.)
