Abstract | Interconnection networks of various topologies are used in parallel computing. It is important to study the graph theoretical/combinatorial properties of the underlying networks in order to better understand them and develop more efficient parallel algorithms as well as fault-tolerant communication/routing algorithms. In this paper, we approach this problem from a new angle by looking into the spectra (eigenvalues and their multiplicities) of these networks. Eigenvalues of the adjacency matrix of a graph can reveal certain properties of the graph since they are closely related to some of its combinatorial invariants. Specifically, for some of the popular interconnection networks, we study their eigenvalues and multiplicities by (1) summarizing the currently available results; (2) deriving some of these results in a more straightforward way; (3) obtaining new results; and (4) presenting experimental results on several interconnection networks. In addition, we briefly survey the results that relate spectra of graphs to their structural properties. Although much work remains to be done, by looking into the spectra of interconnection networks, we hope to bring about a more unified approach to studying their topological properties. |

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.
