Disclosed is a mechanism on receiving processors in a parallel computing system for providing order to data packets received from a broadcast call and to distinguish data packets received at nodes from several incoming asynchronous broadcast messages where header space is limited. In the present invention,...http://www.google.de/patents/US7738443?utm_source=gb-gplus-sharePatent US7738443 - Asynchronous broadcast for ordered delivery between compute nodes in a parallel computing system where packet header space is limited
