[ale] Bonding sanity check

[Greg Clifton]

There is also some potential chance/benefit of having a non-blocking
configuration, esp. on (a) busy network(s). I remember UK (Univ of Kentucky)
having a VERY impressive flop count on a smallish (maybe 48 node AMD Athlon)
cluster using 4 port 10/100 NICs in each node and a hurd of 100MB switches
wired in such a way as to eliminate or at least minimize port blocking at SC
'03, I think, in Phoenix. The Prof in charge said it took a small super
computer to compute the optimum cabling scheme. Anyways, I thought it was a
pretty cool way of building a super computing cluster on the cheap and this
was back in the day when Myrinet was king of the hill @ ~ $2k per node for
high speed low latency connectivity.  If interested, they might still have
the write up posted at aggregate.org.
