Sending rank needs to have an XRC connection with some XRC qp on the local node, and needs a target XRC SRQ belonging to the destination rank.
The destination XRC QP and XRC SRQ must belong to the same XRC Domain (I would assume this is the case anyway, since they are part of the same job -- just mentioning this to be safe). - 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
