Scady: A Scalable & Dynamic Toolkit for Enhanced Performance in Grid Computing

Abstract

Grid computing has resulted in faster execution of applications. Day by day the requirement for execution speed of applications is increasing. To achieve this, suitable middleware is needed and to be configured requirement specific. An application can be executed faster only when there is no node failure or network failure. Moreover, at run time, if a node fails, there should be some alternative arrangement to reconfigure other node to complete the task which was supposed to be done by the failed node. Thus, a middleware is needed that can be configured according to the requirements of the application. Such a middleware would help in increasing the performance of the application. In most of the middleware available presently, dynamic configuration is not facilitated. This has become one of the reasons for the failure of adoption or implementation of Grid in many organizations. This paper analyzes the present GUI Grid - Alchemi with its components and challenges. It also proposes a toolkit-Scady which solves the challenges of Alchemi and provides higher performance. Two experiments are done and their result analysis shows the performance of the proposed toolkit.
