+Segfault when running executables on login nodes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Executing a parallel binary on the login node or a batch node without using the job step launcher ``jsrun`` will result in a segfault. 
+
+This also can be encountered when importing parallel Python libraries like ``mpi4py`` and ``h5py`` directly on these nodes.
+
+The issue has been reported to IBM. The current workaround is to run the binary inside an interactive or batch job via ``jsrun``.

 Nsight Compute cannot be used with MPI programs
