| Abstract | In this paper we present a method for dynamic fault tolerant routing for SCI networks implemented on Dolphin Interconnect Solutions hardware. By dynamic fault tolerance, we mean that the interconnection network reroutes affected packets around a fault, while the rest of the network is fully functional. To the best of our knowledge this is the first reported case of dynamic fault tolerant routing available on commercial off the shelf interconnection network technology without duplicating hardware resources. The development is focused around a 2-D torus topology, and is compatible with the existing hardware, and software stack. We look into the existing mechanisms for routing in SCI. We describe how to make the nodes that detect the faulty component do routing decisions, and what changes are needed in the existing routing to enable support for local rerouting. The new routing algorithm is tested on clusters with real hardware. Our tests show that distributed databases like MySQL can run uninterruptedly while the network reacts to faults. The solution is now part of Dolphin Interconnect Solutions SCI driver, and hardware development to further decrease the reaction time is underway. |

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.
