I mean that j2 has all the QP connections with all other remote jobs, so j2 does not save anything compared with non-SRC case, can this affect j2's performance ? I have another question, when using SRQ, or SRC+SRQ, when a completion is returned by ibv_poll_cq(), is there an easy way to find who sent this message to me ? 'struct ibv_wc' does not say much about the message source rank. The only field is 'src_qp', but I can not find any document about how to use it. Is there any way to return some kind of "source context" ? Or do you think this is application's responsibility to figure out source rank from the message itself ? I hope the source rank can be identified before parsing the message.
