| Abstract | We present a novel approach for parallel analysis of models written in Alloy, a declarative extension of first-order logic based on relations. The Alloy language is supported by the fully automatic Alloy Analyzer, which translates models into propositional formulas and uses off-the-shelf SAT technology to solve them. Our key insight is that the underlying constraint satisfaction problem can be split into subproblems of lesser complexity by using ranges of candidate solutions, which partition the space of all candidate solutions. Conceptually, we define a total ordering among the candidate solutions, split this space of candidates into ranges, and let independent SAT searches take place within these ranges' endpoints. Our tool, Ranger, embodies our insight. Experimental evaluation shows that Ranger provides substantial speedups (in several cases, superlinear ones) for a variety of hard-to-solve Alloy models, and that adding more hardware reduces analysis costs almost linearly. |

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.
