I have not seen any documentation that states it does not support UC, although I have not seen any documentation that says it does either. I have seen documentation regarding RDMA CM that talks about a connection not actually being established between queue pairs when using unreliable datagram (UD), but nothing regarding support for UC. Alan, you haven't specified if you app is user space or kernel space based, I assume the former, I believe that it either just works or can be just made to work... e.g maybe a minor error on your side, or maybe something small to change/complete on the rdma-cm side... I'm copying the maintainer of the kernel rdma-cm and librdmacm, Sean - should there any problem for librdmacm consumers to use UC at their apps?
