Dependable Multicore Architectures at Nanoscale: the view from Europe

This article presents a survey on the dependability of multicore architectures in nanoscale technologies. The survey presents the view from one of Europe’s largest network of academic and industrial scientists collaborating in research and development in the topic. The article first summarizes the major dependability threats for multicore chips. In the second part the different mitigation techniques are described and classified. Then, different dependability metrics and evaluation methods are presented. The paper ends with the conclusions as well as a short discussion of future challenges and research directions for dependable multicore architectures.
