   Hi all,

   I want to use the RDMA CM option of MVAPICH2. The procedure described
   in the user guide is not much informative. Can anyone here give me
the detailed
   procedure for using the RDMA CM option. Also, I'll be glad if some
one can give
   me a document describing how it works in detail.
   Actually I have some doubts like, how the IP addresses (???) are
   resolved into IB    addresses and what happens in the case of nodes two HCAs
   (or 1 HCA with two ports) ?

   In the MVAPICH2 user guide it is mentioned that "RDMA CM device needs
   to be setup, configured with an IP address and connected to the network".
   Is this same as configuring IPoIB device ?
