Dependable computing is normally achieved through various redundancy (such as modular, temporal and/or information) techniques at different levels (for instance, circuit, architecture, runtime, operating systems and software) in the systems. With the scaled technology size and miniaturization of computing systems, faults will become more common and it is imperative for most modern computing systems to deploy various fault-tolerance techniques. On the other hand, redundancy based fault-tolerance generally has energy implications, which warrants careful consideration since energy has been promoted to be the first-class system resource recently. This workshop aims at establishing a forum for practitioners and researchers from both industry and academia who work on different aspects of fault tolerance and system energy efficiency to exchange ideas on how to achieve low-power dependable computing. To cover a broad range of research related to energy efficiency and dependable computing, the workshop will consider various levels (from circuits to software), components (from memory to computation) and systems (from battery-powered embedded systems to large scale reliable servers).
