| Abstract | artificial society is an effective way for social science research. However, in order to meet real-time and super realtime requirement of computational experiment, the execution efficiency of large-scale artificial society then becomes the burning question. The emergence of heterogeneous parallel system offers opportunities and challenges for accelerating large scale artificial society simulation. How to fully utilize heterogeneous computational resources in large scale agent based simulation becomes the key issue. The paper proposes a CPU/GPU-based accelerating computational method, in which GPU is fully utilized in two different ways at the same time. Firstly GPU is treated as host processor, and a GPU based simulation kernel is designed to execute the models collaboratively with CPU simulation kernel. Secondly, in order to accelerate the domain-specific models, a specific domain-oriented GPU simulation computational service component is proposed, and GPU is used as a coprocessor to offer domain-specific parallel optimization. A SPMT (Single Process Multi Threads) based conservative parallel simulation framework is proposed to integrate the GPU simulation kernel and computational service component. At last, an experiment is designed to test the efficiency of GPU based simulation kernel, and argues about the application mode of GPU. |

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.
