I see. My one script for all clusters calls
mpirun --mca btl openib,mx,gm,tcp,sm,self ....
so I'd need to add some logic above the mpirun line to figure out what
cluster I am on to setup the correct mpirun line.
still seems like I should be able to do the mpirun line I have and just
tell me what it found, not what it can't find.
thanks for the workaround...

You can use:
$ mpirun -mca pml ob1 -mca mx,sm,self ...
when running with MX. Substitute gm or ib when running on those
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.
