FWIW, if this configuration is for all of your users, you might want
to specify these MCA params in the default MCA param file, or the
environment, ...etc. Just so that you don't have to specify it on
every mpirun command line.

Matt,
I guess that you have some problem with partition configuration.
Can you share with us your partition configuration file (by default
opensm use /etc/opensm/partitions.conf) and guid from your machines (
ibstat | grep GUID ) ?
Regards,
Pasha

Sorry, misunderstood the question,
thanks for Pasha the right command line will be
-mca btl openib,self -mca btl_openib_of_pkey_val 0x8109 -mca
btl_openib_of_pkey_ix 1
ex.
#mpirun -np 2 -H witch2,witch3 -mca btl openib,self -mca
btl_openib_of_pkey_val 0x8001 -mca btl_openib_of_pkey_ix 1 ./mpi_p

Really? I thought we only took OpenFabrics device names in the
openib_if_include MCA param...? It looks like ib0.8109 is an IPoIB
device name.
