[OMPI users] Parameters at run time

[Raymond Muno via users]

Is there a way to determine, at run time, as to what choices OpenMPI 
made in terms of transports that are being utilized?  We want to verify 
we are running UCX over Infiniband.

I have two users, executing the identical code, with the same mpirun 
options, getting vastly different execution times on the same cluster.
