I want to thank the responders. I'm very new to this and I'm not a systems programmer. I'll be a little more specific about my system. We have started with (count them) fourteen nodes. However, we have plans to expand to something between 32 and 64 nodes. The initial idea was to use the Flat neighborhood network so that we could have single-hop connectivity between any two nodes. My impression now is that to do that would require custom clustering that is outside the model for something like scyld. I have now split the system into two parts. On one I've installed scyld using exactly the networking they envision. (Incidentally, my original posting about scyld, where I was worried about querying on empty networks, was in error. It turns out that during the RARP query, scyld will take an answer on any NIC and proceed. My error was that I hadn't restarted the beosetup daemons after placing the hardware address from eacy node in the center column of the beosetup gui.) The scyld system is now up and I'm starting to deal with the software issues. On the second piece of the system, I want to experiment with FNN and I'm fairly certain that for this, scyld will be completely in the dark. To make FNN work each node needs its own hosts file because the routes between nodes will be over different networks. This implies that each node will have some system on it. My only question now is whether anyone in this community has experience with FNN and whether it is worth it?
