Design and Implementation of Optimized Light-Weight Communication System in Grid

Abstract

The advantage of high-performance networks in conjunction with low-cost, powerful computational machines have made possible the development of a new set of tech- nologies termed "computational grid". These technologies are making possible the creation of very large-scale distributed computing systems by interconnecting geo- graphically distributed computational resources via very high-performance networks. This provides high computational power that can be brought to bear on large-scale problems in several domains. One particularly difficult issue is that of utilizing fully available bandwidth while being in some sense fair to competing traffic flows. It has been widely demonstrated that TCP, the communication protocol of choice for most distributed application, often performs quite poorly in the emerging high-bandwidth high-delay network en- vironments. This has led to significant research on the development of user-level applications that can circumvent some of the performance problems inherent in TCP. The goal of this thesis is to develop Light-Weight Communication System in the Grid. The first initiative is to apply multi-casting features to this protocol & the al- gorithm for the same is developed. Then apply the algorithm on the Grid by using MPI (Message Passing Interface). Reduce the System call, which is not necessary by the Windows at all the time and which consumes more time in background processes. After doing that take the results for the various performance parameters and compare the existing result of various performance parameters.
