| Abstract | Transactional memory (TM) is a recent parallel programming concept which reduces challenges found in parallel programming. TM offers numerous advantages over other synchronization mechanisms, yet many current TM systems require complex hardware, programming language extensions, specific compiler support or enforce impractical software design, making these models unrealistic as an immediate TM solution for early adopters. Our new software transactional memory (STM) system, DracoSTM, is a high performance lock-based C++ STM research library. DracoSTM uses only native object-oriented language semantics, increasing its intuitiveness for developers while maintaining high programmability via automatic handling of composition, locks and transaction termination. DracoSTM is the STM first solution to (1) implement both direct and deferred updating and (2) enable run-time alternation between these updating policies. DracoSTM requires no language extension, specific development environment or platform, widening its usability and increasing the novelty of its design. This paper describes DracoSTM from an architectural infrastructure viewpoint. TM-specific and library-specific aspects are discussed, as are their cross-cutting design concerns. Finally, performance benchmarks are presented, showing DracoSTM outperform another high performing C++ STM library, by upwards of two orders of magnitude. |

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.
