| Abstract | Atomicity violation, a common bug that obsesses multithreaded programs, has made the developing of multithreaded programs a daunting task. Atomicity is a basic correctness property of such programs. We propose strong atomicity, an efficient mechanism that helps programmers to write correct atom blocks with very little effort. We provide atom_start and atom_end for programmers to annotate an atom block. And then our runtime system will efficiently execute the block while guaranteeing atomicity. Unlike transactional memory (TM), strong atomicity permits asymmetrical atomic code regions, which means the execution of atom block not only excludes other atom blocks, but also excludes any other instructions outside atom blocks. Hence, programmers only need to simply wrap the key code region without worrying about the conflicts from outside, which saves programming effort. We have implemented our system and evaluated it with some use cases (writing or fixing multithreaded programs). With the help of our mechanism, writing an atom block is straightforward. Just wrap the block with atom_start and atom_end and it will behave like an atom operation. |

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.
