Inhalt:

Electrical energy is the single most important operating resource to 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 manifold 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 focuses the follow topics:

• power and energy management

• energy accounting

• energy demand analysis

• energy-aware operating-system architecture

• hardware power management (i.e. DVFS, throttling, sleep states)

• thermal management

• storage and file systems

• memory management

• network, wireless, and protocols

• energy-aware server/cluster

• compiler optimisations and code transformation

• display technology

• electricity grid
  

The lecture is linked to the exercises by means of research papers. The students read the papers as private study as preparation for lectures. From there, the research papers are basis for discussion and build the starting point for the assignments of the exercises.

Lernziele und Kompetenzen:

Students who have successfully attended the lecture and exercises have followed the learning objectives and have acquired the competence listed below.

• understanding the importance of electrical energy as operating resource to computing systems

• acquiring the ability to make trade-off decisions in efficient system design (i.e. power demand vs. performance), in particular with regards to operating systems

• modelling the energy demand for individual synchronous and asynchronous operations

• applying strategies to reduce the energy demand for software activities based on specific hardware properties (i.e. sleep states)

• analysing software for critical sections that cause high energy demand
