Transient-fault recovery for chip multiprocessors

Chip-level redundant threading with recovery (CRTR) for chip multiprocessors extends previous transient-fault detection schemes to provide fault recovery. To hide interprocessor latency, CRTR uses a long slack enabled by asymmetric commit and uses the trailing thread state for recovery. CRTR increases bandwidth supply by pipelining communication paths and reduces bandwidth demand by extending the dependence-based checking elision.
