Abstract

Soft errors and aging are two substantial reliability-related problems in today's computing systems. While soft errors are transient in nature, they can lead to wrong application outputs and even application failures. However, aging has permanent effects and results in slower performance and timing errors in processors. In this paper, we will discuss different approaches how these reliability threats can be mitigated in multi-core systems for performance/power-constrained scenarios. Different research challenges and corresponding solutions will be described which jointly target the above-mentioned reliability issues while also considering additional problems like process variation and dark silicon. These solutions are implemented in different system layers and make use of an analysis of and adaptation to the application properties. Moreover, they leverage the opportunities offered by multi-core systems, for instance, to efficiently enable redundant multithreading.
