Reading the code, the following sequence does not work: rdma_join_multicast then rdma_create_qp. The QP does not automatically attach to previously joined multicast groups on creation. (This is a problem with the existing code.) The reverse sequence (create then join) does work. I'm adding the ipoib support to the librdmacm now, but we will still need a separate patch to fix attaching to joined multicast groups when the QP is created. - Sean _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
