In libibverbs, when does completion entry get pushed to CQ?
After a wr has been posted through
ibv_post_sendto a RC, does completion entry get pushed to sender's cq when data has been written to destination buffer and the sender receive an acknowledgement?After a wr has been posted through
ibv_post_sendto a UD, does completion happen as soon as data has been copied out of the local buffer?For the above three cases, do behave differently if it is
IBV_WR_RDMA_WRITEvsIBV_WR_SEND?
