Abstract | Design-time decisions can often only cover certain scenarios and fail in efficiency when hard-to-predict system scenarios occur. This drives the development of run-time adaptive systems. To the best of our knowledge, we are presenting the first scheme for a runtime application mapping in a distributed manner using agents targeting for adaptive NoC-based heterogeneous multi-processor systems. Our approach reduces the overall traffic produced to collect the current state of the system (monitoring-traffic), needed for runtime mapping, compared to a centralized mapping scheme. In our experiment, we obtain 10.7 times lower monitoring traffic compared to the centralized mapping scheme proposed in [8] for a 64 times 64 NoC. Our proposed scheme also requires less execution cycles compared to a non-clustered centralized approach. We achieve on an average 7.1 times lower computational effort for the mapping algorithm compared to the simple nearest-neighbor (NN) heuristics proposed in (E. Carvalho et al., 2007) in a 64 times 32 NoC. We demonstrate the advantage of our scheme by means of a robot application and a set of multimedia applications and compare it to the state-of-the-art run-time mapping schemes proposed in ((E. Carvalho et al., 2007), (C.-L. Chou and R. Marculescu, 2007),(L. Smit et al., 2004)). |

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.
