|Abstract||The integration of novel nanotechnologies onto silicon platforms is likely to increase fabrication defects compared with traditional CMOS technologies. Furthermore, the number of nodes connected with these networks makes acquiring a global defect map impractical. As a result, on-chip networks will provide defect tolerance by self-organizing into irregular topologies. In this scenario, simple static routing algorithms based on regular physical topologies, such as meshes, will be inadequate. Additionally, previous routing approaches for irregular networks assume abundant resources and do not apply to this domain of resource-constrained self-organizing nano-scale networks. Consequently, routing algorithms that work in irregular networks with limited resources are needed. In this article, we explore routing for self-organizing nano-scale irregular networks in the context of a Self-Organizing SIMD Architecture (SOSA). Our approach trades configuration time and a small amount of storage for reduced communication latency. We augment an Euler path-based routing technique for trees to generate static shortest paths between certain pairs of nodes while remaining deadlock free. Simulations of several applications executing on SOSA show our proposed routing algorithm can reduce execution time by 8&percent; to 30&percent;.|

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.
