Dependability Assessment of Operating Systems in Multi-core Architectures

The dependability of a service is directly influenced by the reliability provided by the lower system layers, such as the operating system and hardware. Due to device and voltage scaling, and the increasing complexity of digital systems, transient errors are forecast to be a problem for all future digital systems [4]. When we consider large-scale machines, with many processors and cores, this phenomenon is furthered exacerbated. Therefore, it is mandatory to evaluate the behavior of systems under such conditions.
