hi, I am still working on this problem, but can't solve it.
The problem is: I want to use completion queue element on completion queue associated with received queue (on remote hca) to allow reading databuffer. But I get nothing from the completion queue. In the specification, it says that a CQE should be created (in the remote hca) after performing a rdma write The function ibv_get_cq_event return nothings (it is like while(1) in ibv_get_cq_event) My code is attached, if you have any ideas.
