| Abstract | It is clear from both the cooling demands and the electricity costs, that the growth in scientific computing capabilities of the last few decades is not sustainable unless fundamentally new ideas are brought to bear. In this talk we propose a novel approach to supercomputing design that leverages the sophisticated tool chains of the consumer electronics marketplace. We analyze our framework in the context of high-resolution global climate change simulations C an application with multi-trillion dollar ramifications to the world economies. A key aspect of our methodology is hardware-software co-tuning, which utilizes fast and accurate FPGA-based architectural emulation. This enables the design of future exaflop-class supercomputing systems to be defined by scientific requirements instead of constraining science to the machine configurations. Our talk will provide detailed design requirements for a kilometer-scale global cloud system resolving climate models and point the way toward Green Flash: an application-targeted exascale machine that could be efficiently implemented using mainstream embedded design processes. Overall, we believe that our proposed approach can provide a quantum leap in hardware and energy utilization, and may significantly impact the design of the next generation of HPC systems. |

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.
