I'm using the openmpi-1.1.1-5.el5.x86_64 RPM on a Scientific Linux 5
cluster, with no installed HCAs. And a simple MPI job submitted to that
cluster runs OK .. except that it issues messages for each node like the
one shown below. Is there some way I can supress these, perhaps by an
appropriate entry in /etc/openmpi-mca-params.conf ?

libibverbs: Fatal: couldn't open sysfs class 'infiniband_verbs'.
[0,1,0]: OpenIB on host localhost was unable to find any HCAs.
Another transport will be used instead, although this may result in
lower performance.
