| Abstract | Although there are some researches have been done on the testbeds or architectures for optical grid applications, few efforts have been made on the scheduling problem for the optical grid application in theoretical details. When optical networks are considered as resources and jointly scheduled with other grid resources, communication contention must be taken into consideration for efficient task scheduling. This paper analyzes two schemes for reducing the communication contention in joint scheduling of computation and network resources for optical grid, one is the adaptive routing scheme and the other is grid resource selection scheme. The adaptive routing scheme, that was proposed in another paper [16] can detour the heavy traffic and find an earliest start route for each edge scheduling. A multilevel method for grid resource selection scheme is proposed in this paper, which help to schedule tasks onto the nearby resources, leading to a reduction in the average data transferred across individual links. Simulation results show that when we employ the two schemes together in the joint scheduling model, most of the communication contention can be removed, producing the smallest schedule length with relatively lower link utilization. |

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.
