The foundation of this book is on green computing and its goals are manifold. This book uncovers the flux of technologies and its impact on green landscape. More specifically, it envisions the duality of green computing with technological trends in other fields of computing such as high performance computing (HPC) and cloud computing from one hand; and economy, and business, on the other hand. In green world, research on minimizing energy and resource consumption through algorithmic and software techniques such as monitoring, power-aware consolidation, scheduling as well as user/application profiling and debugging are other aspects of addressing energy efficiency. These solutions are the facets of intelligent computation. These facets of intelligent computation constitute the main parts of resource management. In this book, we address some aspects of intelligent computation as part of resource management and scheduling. This book is addressed at a rather broad audience, but in a nutshell to anyone who is looking at green computing to use it, to learn more about it, or to apply it to her needs.
