| Abstract | We describe an automatic verification method to check whether transactional memories ensure strict serializability a key property assumed of the transactional interface. Our main contribution is a technique for effectively verifying parameterized systems. The technique merges ideas from parameterized hardware and protocol verification--verification by invisible invariants and symmetry reduction--with ideas from software verification--template-based invariant generation and satisfiability checking for quantified formulæ (modulo theories). The combination enables us to precisely model and analyze unbounded systems while taming state explosion. Our technique enables automated proofs that two-phase locking (TPL), dynamic software transactional memory (DSTM), and transactional locking II (TL2) systems ensure strict serializability. The verification is challenging since the systems are unbounded in several dimensions: the number and length of concurrently executing transactions, and the size of the shared memory they access, have no finite limit. In contrast, state-of-the-art software model checking tools such as BLAST and TVLA are unable to validate either system, due to inherent expressiveness limitations or state explosion. |

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.
