Hi all, I have been trying to implement simple client/server system that uses UC instead of RC in order to test the performance of RDMA Writes under UC against RDMA Reads under RC. When I switch from RC to UC, rdma_accept() at the server fails with “Invalid Argument (EINVAL)”. I have tried various values for queue pair attributes and also tried RDMA_PS_IB, RDMA_PS_UDP for rdma_create_id(), but nothing has worked for me. The problem seems to be very similar to what had been discussed in this thread last year: http://www.spinics.net/lists/linux-rdma/msg23071.html, yet I could not find the solution to the problem in the thread. Has there been any development regarding UC since then? I am more than happy to provide more information that would help in resolving this issue.
