The library to send data is libibverbs. The rdma_cm (or librdmacm) is one method that can be used to setup the QPs for communication. I.e. exchange the QP numbers, LIDs, etc. You could also setup the QPs using the libibcm or just exchange the data over a standard socket. If you look at the librdmacm code, you will see that it calls the libibverbs functions to allocate and modify the QP. - Sean _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
