This special session focuses on all aspects of energy-efficient computing in parallel multi- and manycore systems for the dark silicon era. The goal of this special session is to bring together researchers from this community to corporately address challenges that limit higher data-densities and efficient energy utilization in application areas where low power consumption combined with dependable operation is required. The achievements of this special sessions can have a great potential to contribute to the realization of near future computing systems and applications, such as data intensive embedded servers, hand-held consumer devices, and Internet-of-Things. DS-MC2 presents new ideas in the dark silicon aware multi- and many-core systems field such as theory and modeling, scalable and energyefficient design approaches and frameworks, algorithms, analysis and comparison, design techniques and emerging implementations.
