Hi Jeff, You should compile OpenMPI with the "--with-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_i

I see that OpenMPI 1.5.x supports the Mellanox/Voltaire FCA MPI Collective Accelerator. Are any special OpenMPI builb options required to use this? Is the feature runtime selectable? Thanks, -Jeff
