Hpc@green It Green High Performance Computing Methods

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)
