Abstract
Scalable means are provided for diagnosing the health of a parallel system comprising multiple nodes interconnected using one or more switching networks. The node pings other nodes via different paths at regular intervals. If more than a threshold number of pings are missed from a node, the system performs fault detection by entering a freeze state in which nodes do not send or receive any messages except ping messages. If ping messages still fail to reach destination nodes, the parallel system identifies faulty components that are causing ping messages to fail. Once the faulty component is identified, the parallel system is unfrozen by allowing nodes to communicate all messages. If redundant computers and/or switches are present, the parallel system is automatically reconfigured to avoid the faulty components.
