| Abstract | Dehne et al. present a BSP/CGM algorithm for computing a spanning tree and the connected components of a graph, that requires O(log p) communication rounds, where p is the number of processors. It requires the solution of the Euler tour problem which in turn is based on the solution of the list ranking problem. In this paper we present experimental results of a parallel algorithm that does not depend on the solution of the Euler tour or the list ranking problem. The proposed algorithm has the practical advantage of avoiding the list ranking computation and is based on the integer sorting algorithm which can be implemented efficiently on the BSP/CGM model. We implemented the proposed algorithm on a Beowulf cluster and on a grid running the InteGrade middleware. We obtained encouraging albeit modest speedup on a small Beowulf cluster and expect good speedups on the grid for larger size graphs and clusters. |

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.
