I am having the problem of listing nodes in mpd.hosts file on a 4 way SMP machine with each node being a quad-core processor. How should I assign diffferent programs in MPI to different nodes. Our mpd.hosts file looks like
localhost:4 localhost:4 localhost:4 localhost:4
but our machine has only one IP address i.e. we do not know how to give internal addresses to each node. Please help in this regard.
