Abstract :
This paper presents a dynamic scheduling solution to achieve fault tolerance in many-core architectures. Triple Modular Redundancy is applied on the multi-threaded application to dynamically mitigate the effects of both permanent and transient faults, and to identify and isolate damaged units. The approach targets the best performance, while balancing the use of the healthy resources to limit wear-out and aging effects, which cause permanent damages. Experimental results on synthetic case studies are reported, to validate the ability to tolerate faults while optimizing performance and resource usage.
