Are you documenting the setup process for your endeavors, or just blogging
about the result? I think it would be interesting to see how you clustered
those Pi Vaxen as much as to know it was possible. I've got a few Pi around
looking for something to cluster around...
There are three parts to a successful setup:
1. Since each Pi has only one Ethernet interface, make sure you use a
wired connection (wireless isn't real Ethernet)
Well, Wireless is 802.11 which indeed isn't 802.3 / Ethernet. But that's not
really relevant. The question is whether it uses Ethernet addressing and
offers an Ethernet-compatible MAC layer API, and 802.11 certainly does. You
can run SimH Ethernet just fine over a wireless LAN. I've run PDP11 SimH that
way with no problems.
Actually, I have run into problems. The broadcast domain, as well as the
Unicast have slight differences to Ethernet, which makes it sometimes
fail in subtle ways.
Having a second mac address on a WiFi interface, one that is used by
simh, though tun/tap, does not work that well with WiFi. Unfortunately.
I've definitely had problems keeping it working under OS X at least. And
I'm pretty sure I've read of others having the same problem.
