Where is the option 'default-hostfile' described?
Try "mpirun --help". Not everything makes it to the man page. Heck,
not everything is documented!
It does not appear in mpirun's man page (for v. 1.4.2)
and i couldn't find anything like that with googling.

Specify your hostfile as the default one:
mpirun --default-hostfile ./Cluster.hosts
Otherwise, we take the default hostfile and then apply the hostfile as a filter
to select hosts from within it. Sounds strange, I suppose, but the idea is that
the default hostfile can contain configuration info (#sockets, #cores/socket,
etc.) that you might not want to have to put in every hostfile.
