Affected Software: 
MVAPICH2
Quantum ESPRESSO

We have observed that several applications built with MVAPICH2, including Quantum ESPRESSO 7.4.1, HDF5, and OpenFOAM, may experience poor performance on Cardinal. We suspect this issue could be related to the newer network devices or drivers. Since MVAPICH2 is no longer supported, we recommend switching to MVAPICH 3.0 or another MPI implementation to ensure continued performance and stability in your work.
