Anyway, "clustering software" is meaningless. What does "clustering software" do? Queue and run parallel jobs? Set up a communications medium? Do load balancing or high availability between a set of nodes? All those definitions are correct. FWIW, clustering (in the supercomputing sense) can be very simple if you're only building a cluster for a single researcher or research group. You can pretty much just set up an mpi implementation, or pvm, and an hourly passwd rdist, and call it a cluster. MPI and PVM build on all sorts of platforms, and at least MPICH (and probably PVM) have mechanisms for communicating between programs on different architectures. Things get much more complex when you start trying to arbitrate running time between different research units. I won't get in to that now, because it can be an exercise in enormous amounts of excrutiating pain, depending on what your requirements are. -- Gary Jackson bargle@umiacs.umd.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
