| Abstract | Automatic decomposition is a compile technique that maps computation and data onto different processors, and array is one of the main targets processed. Certain arrays, whose migration is the most expensive, are termed as dominant arrays. Since every computing node has its own memory on distributed memory parallel computers (DMPCs), decompositions of dominant arrays have directly impact on the performance of parallel program. To avoid remote data accessing, each definition and use of arrays needs to be distributed consistently, so as that there are too many partition constraints to increase decomposition choices of dominant arrays. We propose an automatic computation and data decomposition algorithm of prioritized dominant array in this paper. Our algorithm ranks arrays according to their potential communication costs, and then finds data decomposition for arrays in the decreasing order of rank. We serialize low rank arrays to enhance the decomposition priority of high rank ones. Finally, serial arrays are to be partitioned if maintaining parallel benefits of previous results. The experimental results show that this algorithm can improve the performance of parallel programs. |

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.
