Electrical energy is the single most important operating resource for computer systems. Although the energy demand of computers is an invisible system property by itself, the impact of energy demand is omnipresent and obvious in various forms of appearance. Sudden system failures (i.e., system breakdowns) and recurrent standard system operations (i.e., power management) serve as practical examples. The lecture discusses the design of energy-aware computing systems and shines light on topics, such as power and energy management, energy demand analysis, energy-aware operating-system architecture.
The lecture is linked to the exercises through research papers. The students read the papers in preparation for lectures. From there, the research papers are the basis for discussion and build the starting point for the assignments of the exercises. As part of the exercises, the students apply concepts and strategies from the research papers to systems and evaluate the impact on the system’s energy efficiency.
