Gilles is right, the script shows only what is used right after MPI_Init,
and it will disregard some of the less mainstreams type of modules, the
ones that are dynamically loaded as needed during the execution. It also
only shows only what is related to libmpi, and ignores everything related
to ORT
Did you strip the libraries already ?
the script will show the list of frameworks and components used by MPI
helloworld.
from that, you can deduce a list of components that are not required,
exclude them via the configure command line, and rebuild a trimmed Open MPI.
note this is pretty pa

Let's try to coerce OMPI to dump all modules that are still loaded after
MPI_Init. We are still having a superset of the needed modules, but at
least everything unnecessary in your particular environment has been
trimmed as during a normal OMPI run.

Run ompi_info; it will tell you all the plugins that are installed.

Hi Gilles,
Thanks for reply
i have configured as below for arm

Hi all,
I am using openmpi-1.10.3.
