I'm trying to look over some software that normally takes 100+ nodes that uses ganglia to assign and monitor jobs. I don't have a hundred nodes and DNS is not working at home. Is it possible for me to set up ganglia with just the one node?
Of course you can ! I used ganglia some times ago on a single machine. You'll have to install all the ganglia process (gmond and gmetad) on the same machine. If I remember well, Ganglia will automatically detect your nodes (thanks to gmond heartbeats).
