| Abstract | Recently, numerous job scheduling techniques have been proposed for improving the efficiency of resource sharing in heterogeneous computational grids. However, as we have noticed, some scheduling algorithms, especially those working in batch mode, are likely to be suffered from deficiencies when extended to an non-dedicated grid environment, where the consistency degree of underlying computing environment is unpredictable. In this paper, we will present an ACO based load balancing approach to ameliorate the resource allocation in such a grid environment. Our load model derives from some typical non-dedicated computational grids and we not only consider the heterogeneity of grid resources, but also take into account the overhead of job transferring among computing nodes. Compared with other load balancing algorithms in the state of the art, our approach differs in the utilization of job granularity and the way load balancing is carried out. In addition, we have evaluated our approach by conducting simulations. The experimental results show that the proposed approach is efficient in promoting the system performance in terms of makespan and resource usage. The paper work is also conducted in the context of GORBA, a global optimising grid resource broker which is developed by our institute. |

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.
