Interconnection Networks, Topology Detection, Mapping, Deadlock
Modern high-performance interconnection networks im plement mechanisms for obtaining explicit topology infor mation. One of these mechanisms is based on a host that explores the network in a centralized way, using "scouting" messages, for discovering the network topology. In this pa per, we analyze the risk of deadlock due to such centralized mapping processes in a source-routing network, also eval uating the probability of deadlock configurations and the impact of those deadlocks on network performance.
