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.

I have a quick question.
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.
