| Abstract | Parallel programming paradigms are commonly characterized by the core metrics of scalability, memory use, ease of use, hardware requirements and resiliency. Increasingly the support of heterogeneous environments, for example a mix of CPUs and accelerators, are of interest. Analysis of the semantics of different classes of parallel programming paradigms and their cost leads to DYCE (Distributed Yet Common Environment), a shared memory, rich but hardware friendly, race and deadlock free parallel programming paradigm that allows for resiliency without the need for explicit check-pointing code. Pointer based structures that span the memory of multiple heterogeneous compute devices are possible. Importantly, data exchange is independent of the specific data structures and does not require serialization and deserialization code, even for data structures such as a dynamic linked radix tree of strings. The analysis shows that DYCE does not require coherence from the system and thus can be executed with near minimal overhead and hardware requirements, including the page table cost for large unified address spaces that span many devices. We demonstrate efficacy with a prototype. |

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.
