Hello list,
I have been given permission to impose my usual defaults on the system. I have been reading documentation for the openmpi-mca-params.conf file. "ompi_info --param all all" did not help. All the FAQ's seem to do was confuse me. I can not seem to understand how to instantiate a simple switch like:

 -mca btl_tcp_if_exclude eth2

I have tried various ways but always seem to get:
keyval parser: error 2 reading file /N/u/rsheppar/Karst/.openmpi/mca-params.conf at line 1:

I would really appreciate a simple example of a proper entry. Thanks.
                      Ray
