Abstract: For today's computer systems, electrical energy is the single most important operating resource. The conscious use of energy resources is motivated by different factors and depends on the respective systems and their application: from "smart dust" and battery-powered mobile systems to large-scale high-performance computing clusters that operate under thermal constraints.


  Energy awareness is a prerequisite for energy-efficient operations of computers, and effects the program design time (i.e., ahead of run time) and program execution (i.e., at run time) at operating-system level.


  This talk presents energy-aware programming techniques that originate in static and dynamic program analyses, and support the design of energy-aware system software. To bridge the gap towards execution time, the talk further discusses Albatross, a runtime system that exploits dynamic electricity prices to ensure cost effectiveness for operating heterogeneous HPC clusters.


  BIO: Dr. Timo Honig is Assistant Professor at Friedrich-Alexander University Erlangen-Nurnberg (FAU) in Germany where he received his Ph.D. in 2017. In the System Software Group at FAU, his research focuses on energy-aware systems. He explores techniques for energy-aware programming, the design of energy-efficient system software, and the energy demand of high-performance computing systems.


  As senior software engineer and research fellow at SUSE Linux GmbH in Nurnberg (Germany) and in the Embedded Hardware Development Group at IBM Research Boblingen (Germany) he gained ten years of industry experience. At the Augsburg University of Applied Sciences (Germany) he received his Computer Science degree. As an active advocate for free and open-source software, Timo contributes articles to the Linux Magazine, and he is a member of ACM and GI.
