| Abstract | Minimizing the make-span of the entire divisible load is the primary objective of multi-installment scheduling in heterogeneous parallel and distributed systems. This is a significantly difficult problem to address because we have to find the optimal number m of installments, optimal number n of processors taking part in computation, and optimal load partition A = $[α_{ij}]_{n×m}$ with each element represents the load fraction assigned to each processor in different installment. Therefore, this problem involves 2+n m variables. In this paper, we first find the function expression of the optimal load partition A with respect to the number m of installments and the number n of processors participating in computation, i.e., A = f (n, m), thereby reducing the dimension of the problem down to 2. Then we propose a new heuristic method for finding the optimal numbers of installments and processors. Finally, experimental results show that the make span of the entire divisible load obtained by the proposed method is smaller than those by the existing multi-installment scheduling methods, which implies the effectiveness of the proposed method. |

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.
