FAULT RECOVERY ON A MASSIVELY PARALLEL COMPUTER SYSTEM TO HANDLE NODE FAILURES WITHOUT ENDING AN EXECUTING JOB

摘要

A method and apparatus for fault recovery of on a parallel computer system from a soft failure without endingan executing job on a partition of nodes. In preferred embodiments a failed hardware recovery mechanism on a service node uses a heartbeat monitor to determine when a node failure occurs. Where possible, the failed node is reset and re-loaded with software without ending the software job being executed by the partition containing the failed node.
