That’s correct. I have prefixed them with OMPI_MCA_ when I defined them in my environment. Despite that I still see some of these files being created under the default directory /tmp which is different from what I had set.

When you defined them in your environment did you prefix them with 'OMPI_MCA_'? Open MPI looks for this prefix to identify which parameters are intended for it specifically.
