In general, use of the rdma or ib cm will not help detect failures on active connection any faster. If the remove process dies, it may, since the remote ib cm will try to disconnect on the user's behalf. >Again, if there is cable issue, is there still a DISCONNECT event >generated eventually ? No - the disconnect event comes from a disconnect request being generated by the remote side. You would need to look for a QP error instead. - 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
