|Abstract||Chip multiprocessor (CMP) is becoming an attractive platform for applications seeking both high performance and high energy efficiency. In large-scale CMPs, the communication efficiency among cores is crucial for the overall system performance and energy consumption. In this article, we propose a ring-based optical network-on-chip, called SUOR, to fulfill the communication requirement of CMPs. SUOR effectively explores the distinctive properties of optical signals and photonic devices, and dynamically partitions each data channel into multiple sections. Each section can be utilized independently to boost performance as well as reduce energy consumption. We develop a set of distributed control protocols and algorithms for SUOR, but physically allocate the corresponding cluster agents close to each other to benefit from the strengths of optical interconnects at long distances as well as electrical interconnects at short distances. Simulation results show that SUOR outperforms the alternative optical networks under a wide range of traffic patterns. For example, compared with MWSR design, SUOR achieves 2.58× throughput as well as saves 64% energy consumption on average in a 256-core CMP. Compared with MWMR design, SUOR achieves 1.52× throughput and reduces 73% energy consumption on average.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
