Since I've gotten a couple pieces of mail about this, I thought I would clear up what might be a general misconception. I am the system administrator for an Ncube-10 at UVA. We have a 64-node Ncube-10. The Ncube-10 has a max capacity of 1024 nodes. (Actually more than that, but I'm pretty sure no one has done that. Apparently you can connect several Ncube-10's across the backplane.) Just because someone has an Ncube-10 does not mean that it has all of its processor board slots filled. I wish! :-) Does anyone have or know of accounting software for the Ncube-10? Something that would provide that kind of accounting you would need to sell machine time. (connect, i/o, cpu, that kind of thing). My other problem is mail. The ncube-10 mail software doesnt support the standard internet headers (or whatever those are). Has anyone sucessfully ported a standard Unix mailer to the Ncube-10? The graphics subsystem that we have for the machine is a real pain to program. There is some evidence that we may have been given the wrong software upgrade by Ncube. Anyone have a graphics subsystem that is working just fine? (Programming it, that is: our demos run fine.) The graphics are really nice, otherwise. I think I posted the wrong arpa net address. I had posted: rmw6x@hudson.virginia.acc.edu it is in fact: rmw6x@hudson.acc.virginia.edu Sorry about the wrong address and the load on bitnet! -Bob Wise

The NCube-10 has 11 DMA channels per node. The 11th channel is routed to the back-plane for I/O. While you could upgrade the N-cube to a 2^11 machine, it would mean no I/O, which doesn't make it very useful. If you want to shove in more than 2^10, you'd have to change the topology.
