About libibverbs:
libibverbs is a low-level layer that allows one to use RDMA in his code, it uses RDMA technology primitives that were defined in the InfiniBand specifications
Roland Dreier started the development of this library, but now it is maintained by other people.
And librdmacm is an attempt to make the RDMA programming closer to socket programming.
