does a beowulf cluster act as one computer. I need to know, I'm trying to get my parents to lett me take some old computers off the IT person at school, and I need a use for building a cluster other than as an educational project. I'm planning on using the beowulf as a firewall/server. Can it be done?
I was under the impression that cluster would be useful for processor heavy uses. So the cluster would not have all the hard drives act as one? I kind of need a real application for this, but if there is no way to make the hard drives act as one, then I'll find another use for it.
could I set up the HD from these computers to set up a RAID array across the six different machines? I don't need to rip DVDs, but computing pi would be kind of cool. These coputers are useless on their own, so a 2.4Ghz P4 would be able to copute pi faster than this cluster would, but even still.
I don't know about that one. That is an interesting question, but I really don't know enough about clustersto say yes or no. My guess would be no becuase, (again just what I think I am be wrong) each computer has to have its own OS. But it would be worth looking into. There is a live CD made for clustereing you might want to check them out.
Distribution: Ubuntu 11.4,DD-WRT micro plus ssh,lfs-6.6,Fedora 15,Fedora 16
i seriously doubt you could virutal raid the hard drives, simply because of the drastic speed diference between the IDE interface and even gigabit ethernet connectons. the network would be just too slow to synchronize that much data... although i'm sure someone is going to correct me on this one...
