Zusammenfassung:A method and apparatus for fast backup of a set of compute nodes to save the state of the software in a parallel computer system. A fast backup mechanism in the service node of the computer system configures a set of nodes to be used for a backup and when needed uses the network hardware to perform a fast backup from node to node from an original set of nodes to the backup set of nodes. In the preferred embodiments a the fast backup is done with respect to a midplane or rack of nodes copied to a backup rack of nodes.
