No tagged release of OpenMPI 4.0.x supports UCX 1.7. OpenMPI devs blame UCX's unstable API. Unfortunately some software installs UCX 1.7, such as Mellanox OFED drivers. Why a major network driver distribution wasn't regression tested for compatibility with a flagship communication library remains a mystery.
