Roland: If I only want to send/recv 4 bytes with immediate data: On sender side: opcode = IBV_WR_SEND_WITH_IMM; imm_data = my_4_bytes_data;
Do I still need to specify sg_list and num_sge ? On receiver side, because the immediate data is inside the completion structure, do I need to post a receive for above message ? If I need to post a receive, do I need to specify sg_list and num_sge for the receive ? I looked the spec but did not find useful information. The reason I ask is that at some point, I can not(or hard) to provide registered memory only for 4 bytes data.
