PVM seems to be majorly fubar'd. I'm having all kinds of trouble getting pvmd to even spawn the slave daemons on the other hosts, much less actually run code. At the moment, I don't have the time to dig into it deeply and find out exactly what's wrong, although the general indication from a few Google searches is that PVM is not liking the hosts file on each node or DNS arrangement in the cluster. I should be able to look into that in the next week or two. I'd love to see PVM support on the level of MPI support in ParallelKnoppix (ideally, there would be a choice at the end of the setup process: "what message-passing environment would you like to start? (MPI/PVM/none)").

Has anyone else gotten PVM working on more than just one node?
