Listing nodes in mpd.hosts on SMP machine

Listing nodes in mpd.hosts on SMP machine's picture

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


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.

How about giving each job a separate list in I_MPI_PIN_PROCS ? Admittedly not entirely convenient, as you will have to look up the core numbering.
