Gilles' question is correct; the larger point to make here: the openib BTL is
obsolete and is actively replaced by the UCX PML. UCX is supported by the
vendor (NVIDIA); openib is not.
If you're just starting a new project, I would strongly advocate using UCX
instead of openib.

Hi Ben,
have you tried
export OMPI_MCA_common_ucx_opal_mem_hooks=1
Cheers,
Gilles

Ok, I a am newbie supporting the a HPC project and learning about MPI.
I have the following portion of a shells script:
export OMPI_MCA_btl_openib_allow_ib=1
export OMPI_MCA_btl_openib_if_include="mlx5_0:1"
mpirun -machinefile ${hostlist} \
--mca opal_common_ucx_opal_mem_hooks 1 \
-np $NP \
