To send perform a zero-byte RDMA-read/write, you should assemble a WQE with no scatter/gather entries (see IBSPEC 1.2, volume 1, section 11.4.1.1, table 94 -- Work Request Modifier Matrix, footnote b). A s/g entry with its length field = 0 is interpreted as requesting 2 gigabytes. Is this the problem? - Jack _______________________________________________ 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
