Abstract | We consider the problem of execution time prediction for non-deterministic bulk synchronous computations on multiprocessors. We formulate the evolution of the execution time of a processor as two random workload change models: additive and multiplicative. These two models reflect parallel commutations in which the workload change of a processor is independent of its workload and proportional to its workload, respectively. We take advantage of their salient features and show that approaches based a central limiting theorem in statistics are viable to approximate the execution time after a certain transient time interval. By an elegant coordination of some results from order statistics and convergence rates in the central limiting theorem, we derive explicit bounds on the execution time under some mild assumptions on distributions. The accuracy of the prediction is analyzed rigorously and verified by simulations. |

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.
