| Abstract | Worldwide data centers consume about 300 billion kWh of energy per year, which accounts for 2% of total electricity use. As MapReduce becomes the mainstream paradigm for data-intensive computing in data centers, optimizing MapReduce energy efficiency can greatly mitigate energy requirements and reduce energy bills. Numerous studies have attempted to improve MapReduce energy efficiency, but few have approached this problem from understanding and reducing the energy impact of data movements. As data movements are often performance and energy bottlenecks, we propose a data movement centric approach and present an analysis framework with methods and metrics for evaluating costly built-in MapReduce data movements. Our experimental investigation leverages the fine-grained performance and power profiling framework eTune and reveals unique system-level and component-level energy characteristics of data movements. It also shows the scalability of energy efficiency with MapReduce workload and system parameters. These energy characteristics can be exploited in system design and resource allocation to improve data-intensive computing energy efficiency. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
