Abstract:
A method of selecting a coordinator node to configure a parallel processing system having a local node interconnected with a plurality of interconnected remote nodes, comprising the steps of:(a) multicasting a first set of desired nodes and a first set of reachable nodes from the local node; (b) receiving a remote set of desired nodes and a remote set of reachable nodes from a remote node; (c) setting the first set of desired nodes to the remote set of desired nodes when the remote set of desired nodes has more members than the first set of desired nodes; (d) setting the first set of reachable nodes to the remote set of reachable nodes when the remote set of reachable nodes has more members than the first set of reachable nodes; (e) repeating steps (b)-(d) for all remote nodes in the first set of desired nodes; (f) selecting the candidate coordinator node as the node originating the first set of reachable nodes; and (g) selecting the candidate coordinator node as the coordinator node if the first set of reachable nodes includes all nodes in the first desired set of nodes.
