FAST BACKUP OF COMPUTE NODES IN A MASSIVELY PARALLEL COMPUTER SYSTEM

摘要

a set of compute nodes to save the state of the software in a parallel computer system, a method and system for fast backup relates . The fast backup mechanism in the service node of the computer system performs a fast backup to the backup set of nodes for each node from the initial set of nodes consisting of a set of nodes to be used as a backup and when needed by the network hardware . In a preferred embodiment, the fast backup is done with respect to the midplane or rack of nodes copied to a backup rack of nodes .
