Does the ganglia stuff work? Ganglia makes heavy use of multicast (you won't see anything in ganglia at all if multicast is not working). If you have some multicast network stuff setup different than standard you may have to make some alterations to the gmond.conf file but if not ganglia in theory should work out of the box with now tweeking assuming your switch is configured correctly and has good support for multicast.

Basically, each process searches for other processes, they all talk to each other and start getting their work done. It's a distribution hack. Outside of the Beowulf cluster, our software works fine and we have multiple machines talking to each other with no problems. However, inside the cluster, multicast doesn't seem to work. Each node when it runs the process can see its own messages, but they can't see anyone else's. I have shut pfilter down on all the boxes and the head node in case that was blocking the multicast, but it did not help. We're using a gigabit switch to connect the nodes, but it doesn't have any configuration options on it at all. Any tips? Thanks, Brian Brian E.
