Green High Performance Computing Methods

• Format: PDF

Produktbeschreibung

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.

Autorenporträt

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.

Rezensionen

Aus den Rezensionen:

"... wird die Relevanz dieses Buchs schnell klar. Dieses systematische Buch setzt sich dafür ein, dass so wohl Rechenleistung als auch Stromverbrauch bei Hochleistungsrechnern realistisch ... ist das Buch eine Inspirationsquelle für alle, die sich mit der Verbrauchssenkung bei schnellen Rechnern befassen."

(in: Bulletin electrosuisse, 2/July/2010, Issue 7, S. 121)

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."
