The priorities of different RPIs can be changed in one following ways as
described in section 6.3.2 in the LAM User Document:
- setting the rpi_<rpi_name>_priority SSI parameters to the appropriate
values using the
-ssi rpi_<rpi_name>_priority <value>
command-line switch at runtime.
- setting the LAM_MPI_SSI_rpi_<rpi_name>_priority environment variable to
the approapriate priority value before invoking mpirun.
You can also override the priority-based RPI selection scheme by
specifying the rpi SSI parameter using the
-ssi rpi <rpi_name>
switch to mpirun. This will cause only the specified rpi to be examined
and selected (if possible).
