Abstract
High Performance Computing (HPC) systems consume a lot of energy. The overall energy consumption is one of the biggest challenges on the way towards exascale computers. Therefore, energy reduction techniques have to be applied on all levels from the basic chip technology up to the data center infrastructure. The READEX project explores the potential of dynamically switching application and system parameters, such as the clock frequency of the cores, to reduce the overall energy consumption of applications. An analysis is performed during application design time to precompute a tuning model that is then input to the runtime tuning library. This library switches the application and system configuration at runtime to adapt to varying application characteristics.
