This is normal, and not an InfiniBand

Thanks George!
I've added:
--mca btl_openib_if_include mthca0
--mca btl_openib_warn_default_gid_prefix 0
and hopefully it'll do the right thing without any warnings.

In trying to get openmpi up and running on a new cluster, I came across

Hi Roberto,
I think that you can do what you want if you use an appfile with something
like this:
-host node1,node2,node3 -np 6 -wdir /WorkingDir/ appname
-host node4 -np 2 -wdir /DifferentWorkingDir/ appname
Then run your program using "mpirun --app appfilename".
