Transient faults will soon become a critical reliability concern for processors used in mainstream computing. As the mainstream commodity market accepts only low-cost solutions for transient-fault tolerance, traditional high-end solutions are not acceptable due to their prohibitive costs. This paper presents Epipe, a hybrid software/hardware solution that provides sufficient fault coverage with affordable...
Recently, researchers have shown that exploiting symptom-based solutions provides a promising way to achieve low-cost fault tolerance. However, these solutions cannot provide enough reliability due to lack of ability to handle silent data corruptions (SDCs). To address SDCs efficiently, it is important to identify them effectively. This paper presents an intelligent fault injection framework, SmartInjector,...
As semiconductor technologies scale down to deep sub-micron dimensions, transient faults will soon become a critical reliability concern. This paper presents the Reliability Enhancement Exploiting (REE) technique, a software-implemented fault tolerance solution which employs idempotent property of applications. An idempotent region of code is simply one that can be re-executed multiple times and still...
Fault-tolerance has become an essential concern for processor designers due to increasing transient fault rates, even for the processors used in the mainstream computing. As the mainstream commodity market accepts only low-cost fault tolerance solutions, traditional high-end solutions are unacceptable due to their expensive overheads. This paper presents EnHTM, a hybrid software/hardware implemented...
In the space radiation environment, a large number of cosmic rays often lead to transient faults on the on-board computer. These transient faults result in data flow errors or control flow errors during program running. The present software implemented hardware fault tolerant technology mainly uses the signature analysis method to realize the control flow checking, namely, through assigning signature...
