Default implementation of collectives is based on PML (p2p layer) that is implemented on top of BTL. Consequently it laverages RDMA capabilities to some extend.

Is there an openib (in btl framework) equivalent in coll framework? I have an MPI application with gatherv and scatterv. I am wondering if I can leverage RDMA capabilities of the underlying Infiniband fabric.
