When, for example, I run on an IB cluster, I get warning messages

What I'd like is to not get warnings about what I don't have on the
cluster
in question and instead get a note that says it found the IB.
Is this already possible?
Or can I at least suppress the warnings for the not-found
interconnects?
thanks!

You can use:
$ mpirun -mca pml ob1 -mca mx,sm,self ...
when running with MX. Substitute gm or ib when running on those
networks.
It may still fail over to TCP. To avoid that, you could run:
$ mpirun -mca pml ob1 -mca ^mx,^ib,^tcp ...
to tell it to run on anything (GM, shared memory and self) except MX,
IB, and TCP.
You probably do not need -mca pml ob1, but that will prevent the MX
MTL from trying to start as well.
