David,
ib0 means IP over IB
this is *not* what you want to use since it is way slower than native
infiniband.
if you
mpirun --mca self,sm,openib ...
on more than one node, the only btl usable for inter node communication is
openib,
so if communication happen, that means opening is used.
in order

We appear to have a correctly setup Mellanox IB network (ibdiagnet, ibstat,

But openMPI programs (test and user) that are specifying the
'openib,self,sm'
paramenters do not seem to be using the IB network according to network-
