Minor quibble, Paul: that looks like 127.0.0.1/8 to me, not /24...
I have no specific help to offer for this issue though, sorry.Right, I think I put my IP hat on backwards.Either way, the loopback interface exists and so the warning is a sign that something is amiss.FWIW:Trying "mpirun -mca btl self,sm -np 2 examples/ring_c" still hangs (w/o this warning).So, I doubt that issue is related to whatever is going on with respect IP interfaces.-Paul--Paul H.
