| Abstract | Large volume of data is produced by various applications in the world, processing such scale of data has great challenges in not only performance but also energy efficiency. Researchers propose various techniques to either improve the performance or the energy efficiency. The techniques of these two trends, however, are significantly different. When both performance and energy efficiency are concerned in the big data systems, how to get balance has become an issuing and challenging problem for data center administrators and hardware designers. In this paper, we conduct comprehensive evaluations on two representative platforms with different types of processors. We quantify the performance and energy efficiency, relating the evaluation results to micro-architectural activities and application characteristics. Two interesting findings are made from our evaluations: (1) the performance and energy efficiency are not only determined by the hardware technology, but also associated with the application characteristics; (2) there is no ever-victorious microprocessor in terms of both performance and energy efficiency in all the big data workloads. Based on the findings and quantified evaluation results, we provide great guidance and implications for both data center administrators and big data system designers, and we argue that a hybrid-core is an efficient way to improve the energy efficiency of big data systems with minimum performance degradation. |

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.
