Comparative analysis of workflow and performance characteristics in Cluster and Desktop Grid

To improve the efficiency of computation and to reduce its execution time becomes necessary for any large application which consumes huge processing cycle. For this reason many concepts and programming models are evolved. Out of those concepts concurrent execution of small units of the same application gives better performance. This paper addresses the comparison of efficiency and performance of computing in multiprocessor and multicomputer environment. A set of tasks having various sizes is run in normal programming environment, multiprocessor environment and multicomputer environment in order to analyze the performance. The empirical results illustrate that the performance is optimal in multiprocessor (Cluster) system.
