Hi Jeff, You should compile OpenMPI with the "--with-fca=<path_to_fca>" option. Then you can configure it the the following mca runtime options: coll_fca_enable - whether or not fca is enabled coll_fca_np - from which np to use fca coll_fca_enable_barrier coll_fca_enable_bcast ...
See more options with ompi_info --all | grep fca command. Regards, Andrew Senin.
