Tim Prins gives some additional tips about how to add a new component
to Open MPI.

Hi Aurelien,
Thank you for the pointers. I was able to plug in a component to an
existing framework.
Thanks again,

Re: [OMPI devel] Adding a new component
Hi Sajjad,
First it will depend wether you are writing a new component in an
existing framework (let say you are writing a new BTL for a new
type of interconnect) or a totally new framework (you want to have
a family of component that can manage a totally new functionality
in Open MPI). In each Framework there is a "base" which take care
of the component selection process. If you are just adding a
component, you will just need to provide a mca_mycomponent_init
(bool enable_progress_threads, bool enable_mpi_threads) as
described in the mca_component_t structure. The
mca_framework_base_select will then take care of everything for
you. If you want to add a new framework you'll have to create a
selection function by yourself (all along with a full bunch of
other functions to populate the base of the framework). I'll give
you more details on this if it is relevant for you, just ask.

Hi,
I am a complete newbie to Open MPI internals and just began
browsing the code and reading up on slides and papers. From what I
have read, I learned that I have to create a new component. What I
do not know is how to make MPI aware of it or should I say make MPI
open and select my component. I found a set of slides that briefly
went over adding components. For example, it briefly described that
I must add PARAM_INIT_FILE and PARAM_CONFIG_FILES options in
configure.params, but I'm not sure what these mean. Does anybody
know of any tutorials/documents that could help me with this?
Any help is greatly appreciated.
S Tabib
