Making the most ef?cient use of computer systems has rapidly become a leading topic of interest for the computer industry and its customers alike. However, the focus of these discussions is often on single, isolated, and speci?c architectural and technological improvements for power reduction and conservation, while ignoring the fact that power ef?ciency as a ratio of performance to power consumption is equally in?uenced by performance improvements and architectural power red- tion. Furthermore, ef?ciency can be in?uenced on all levels of today’s system hi- archies from single cores all the way to distributed Grid environments. To improve execution and power ef?ciency requires progress in such diverse ?elds as program optimization, optimization of program scheduling, and power reduction of idling system components for all levels of the system hierarchy. Improving computer system ef?ciency requires improving system performance and reducing system power consumption. To research and reach reasonable conc- sions about system performance we need to not only understand the architectures of our computer systems and the available array of code transformations for p- formance optimizations, but we also need to be able to express this understanding in performance models good enough to guide decisions about code optimizations for speci?c systems. This understanding is necessary on all levels of the system hierarchy from single cores to nodes to full high performance computing (HPC) systems, and eventually to Grid environments with multiple systems and resources.
Pervasive Cloud Computing Technologies: Future Outlooks and Interdisciplinary Perspectives
Technology trends may come and go, but cloud computing technologies have been gaining consideration in the commercial world due to its ability to provide on-demand access to resources, control the software environment, and supplement existing systems. Pervasive Cloud Computing Technologies: Future Outlooks and Interdisciplinary Perspectives explores the latest innovations with cloud computing and the impact of these new models and technologies. This book will present case studies and research on the future of cloud computing technologies and its ability to increase connectivity of various entities of the world. It is an essential resource for technology practitioners, engineers, managers, and academics aiming to gain the knowledge of these novel and pervasive technologies.
Making IT Sustainable
Making IT Sustainable: Techniques and Applications delves into how energy efficiency improvements and renewable energy use in Information Technology (IT) or broader – in Information Communications Technology (ICT) – can contribute to the goal of remediating the impact of climate change. New technologies to reduce the IT carbon footprint are investigated and new methods of server high-density liquid cooling and intelligent power management in data centers are discussed. The book asks several insightful questions: How can environmentally sustainable data centers be built? How do we compare the carbon footprint of data centers versus public cloud, and cloud-focused IT sustainability standards? As growth in data traffic such as video streaming requires additional internet infrastructure, leading to higher emissions, how is this challenge being addressed and how can we improve energy efficiency in IT such as Adiabatic Reversible Computing, use of direct current, and dematerialization are discussed? For many companies and organizations, IT sustainability is becoming important in the environmental category of Corporate Social Responsibility (CSR). This book provides actionable, practical information for IT companies to develop their IT sustainability programs. IT directors and managers responsible for these programs will find the book useful. As pros and cons of various technology solutions for achieving IT sustainability are critically reviewed in detail, the book can serve as a practical guide for IT professionals working on implementing IT sustainability solutions. - Presents various initiatives to address IT sustainability, looking at approaches for improving energy efficiency in IT such as Adiabatic Reversible Computing, use of direct current, and dematerialization - Focuses on the design of sustainable IT systems and aims to be solution oriented - Reviews innovations in software development that contribute to GHG emission reductions such as Rust programming language - Investigates innovations in data center technologies, green software, adiabatic reversible computing, and cloud computing
