Transient-fault recovery using simultaneous multithreading [PDF]

Proceedings 29th Annual International Symposium on Computer Architecture, 2002
We propose a scheme for transient-fault recovery called Simultaneously and Redundantly Threaded processors with Recovery (SRTR) that enhances a previously proposed scheme for transient-fault detection, called Simultaneously and Redundantly Threaded (SRT) processors.

Cooperative Application/OS DRAM Fault Recovery [PDF]

, 2012
Exascale systems will present considerable fault-tolerance challenges to applications and system software. These systems are expected to suffer several hard and soft errors per day. Unfortunately, many fault-tolerance methods in use, such as rollback recovery, are unsuitable for many expected errors, for example DRAM failures. As a result, applications
