Abstract | Many-core computing has surfaced as a promising solution to satisfy the rapidly increasing computational needs for various areas ranging from embedded to datacenter computing. However, when allocated with an excessive number of cores, multithreaded applications may fail to achieve optimal performance and energy efficiency due to the contention on software and/or hardware resources. While previous research has proposed adaptive techniques such as thread packing (TP) and dynamic threading (DT), they often lead to suboptimal results because they are used in an isolated manner. To address this problem, we propose RMC, an integrated runtime system for adaptive many-core computing. Guided by the runtime information of parallel applications, RMC dynamically adapts their execution by combining the TP and DT techniques. We apply RMC to six PARSEC benchmarks that use representative parallelism models (i.e., fork-join, task, and pipeline). We demonstrate that RMC is easy to use, considerably outperforms the state-of-the-art techniques for three PARSEC benchmarks, and incurs a small overhead to the rest of the benchmarks. |

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.
