[Hatle, Steven J.]

How does BusNet work? I've got a bunch of Force 2 and  Force 5 Sparc boards
and a suitable 6U card enclosure, and I'd love to make a "mini-cluster" out
of them, or at least do more than stare at them in the pile.  .  .

VMEbus doesn't support cache coherency so SMP across the backplane won't
work. There are other possibilities though. You could run SMP on each board
and then cluster the boards with Beowulf software. You could get 42 CPUs in
a 19" rack using commercial 21 slot VMEbus subracks. You could also use
BusNet to run TCP/IP across the VMEbus backplane and get about 20 MB/s
between boards.
