A distributed system is a collection of independent computers that appear to the users of the system as a single computer. The distributed system uses relatively cheaper computer systems with commodity hardware and by interconnecting them through high speed network it is possible to implement many features which were not possible earlier. The main advantages of the distributed systems are: availability, reliability, scalability and communication. It is possible to improve the performance of the applications executed in the distributed systems by carrying out parallel computations on the computers connected in the distributed system in a transparent manner (distributed and parallel processing).

In this research center, we plan to do the following activities: (i) To provide training in Hadoop DFS, BlobSeer DFS and Mapreduce framework (used for distributed and parallel programming) (ii) To carry out research activities in distributed file system particularly for improving the performance of the read operations done on the DFS.
