Can you explain what you mean / what you did?

E.g., did you build your algorithm code inside an OMPI tree and now
have an mca_coll_<whatever>.so file? If so, a "make install" should
put that dynamic shared object (DSO) in the Right location in the OMPI
installation tree such that an "ompi_info | grep coll" should show
your component along with the others that OMPI installs.

If all that happens properly, and you set your communicator query
priority high enough (from inside the module query function), your
component should get called for the back-ends of the various MPI
collectives.
