Green High Performance Computing Methods
Authors: Gruber, Ralf, Keller, Vincent
Free Preview- Offers guidelines on how to improve existing applications in a company with the goal of reducing computer energy consumption
- Computers and applications are parameterized, the relevant quantities monitored, and models are presented to predict execution times based on historical data
- Shows how to adjust automatically the frequency of each core to the needs of the application tasks running on it

- About this book
-
The authors present methods to reduce computer energy consumption by a better use of resources and by maximizing the efficiencies of applications. The processor frequency is adjusted to the needs of the running job, leading to a power drop in servers and PCs, and increasing battery life time of laptops. It is shown how computer resources can be optimally adapted to application needs, reducing job run time. The job-related data is stored and reused to help computer managers to stop old machines and to choose new ones better adapted to the application community.

Ralf Gruber won the Cray Gigaflop Performance Award in 1989 with world’s fastest parallel program running at 1.7 GFlop/s sustained. He was responsible for the Swiss-Tx cluster project, a co-operation between EPFL, Compaq, and Supercomputing Systems. Since 6 years he teaches the doctoral school course on "High Performance Computing Methods".
Vincent Keller received his Master degree in Computer Science from the University of Geneva (Switzerland) in 2004, and his PhD degree in 2008 from the Swiss Federal Institute of Technology (EPFL) in the HPCN and HPC Grids fields. Since 2009, Dr. Vincent Keller holds a full-time researcher position at University of Bonn in Germany. His research interests are in HPC applications analysis, Grid and cluster computing and energy efficiency of large computing ecosystems.

From the reviews:
"The current book "HPC@Green IT" by Ralf Gruber and Vincent Keller is unique in addressing all of these topics in a coherent and systematic way and in doing so fills an important gap. The methods presented and their integration have the potential to influence power efficiency and consumption on various scales of the system architectures and should ultimately help the ‘greening’ of HPC computing. "
Dr. Erich Strohmaier, Lawrence Berkeley Laboratory, August 2009
“The book familiarizes readers with this topic and provides a collection of techniques for green high-performance computing (HPC). … In summary, this well-written book includes a lot of colorful graphs/charts, tables, and benchmark results. … Whereas the authors mainly discuss techniques like frequency scaling (to reduce power usage) and compiler optimization (to reduce execution time), there are other techniques that can improve a system’s efficiency--for example, dynamic powering on/off servers.” (Michele Mazzucco, ACM Computing Reviews, August, 2010)
