| Abstract | We suggest a fuzzy based scheduling policy, which not only considers the distributed ownerships and heterogeneous environments but also handles the dynamic state of the cluster (load etc) more effectively. The algorithm aims at finding the best schedule for the combined set of jobs using fuzzy logic. Two fuzzy membership functions, resource fuzzy set and priority fuzzy set, are computed based on each job's requirements against each available node and user priority and are combined using a convex combination of fuzzy numbers to arrive at a final fuzzy value. This value indicates the extent to which the job can be executed on the given node. The result, of this formulates a score matrix, which is converted to a cost matrix and solved for minimum cost using the Hungarian approach of assignment. One of the important factors in this approach is that of deciding weights for the resources. We argue that the weights for each resource cannot be static. We propose a pairwise comparison of all resources to arrive at the weights for each resource for each job. This framework we feel is highly scalable and adapts to dynamic changes in the cluster. Unlike the other approaches, which primarily address the issue of locating a resource that matches the jobs' requirements, this method addresses the issue of performance/throughput of the cluster also. |

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.
