Try something similar to this
mpirun -np 1 -mca btl self,tcp -mca btl_tcp_if_include en1 NetPIPE_3.6/
NPmpi : -np 1 -mca btl self,tcp -mca btl_tcp_if_include en0
NetPIPE_3.6/NPmpi
You should then be able to specify a different if_include mask for you
different processes.

I should have added that the two networks are not routable,

over one specific network which is configured over
e1000g0 on the first set of machines and on e1000g1 on the
second set. I cannot use - for obvious reasons to either
include all of e1000g or to exclude part of e1000g - if that is
possible.
So I have to exclude or include on the internet number range.
Is there an obvious flag - which I have not yet found - to tell
mpirun to use one specific network?
