Abstract
Grid Computing refers to the development of high performance computing environment or virtual super computing environment by utilizing available computing resources in a LAN, WAN and Internet. This new emerging research field offers enormous opportunities for e-Science applications such as astrophysics, bioinformatics, aerospace modeling, cancer research etc. Grid involves coordinating and sharing of computing power, application, data storage, network resources etc., across dynamically and geographically dispersed organizations. Most Grid environments are developed using Globus toolkit which is a UNIX/Linux based middleware to integrate computational resources over the network. The emergence of Global Grid concept provides an excellent opportunity for Grid based e-Science applications to use high performance super computing environments. Thus windows based enterprise grid environments canât be neglected in the development of Global Grids. This study discusses the basics of enterprise grids and the implementation of enterprise computational grids using Alchemi Tool Kit. This review study is organized into three parts. They are (i) Introduction of Grid Technologies, (ii) Design Concepts of Enterprise Grids and (iii) Implementation of Computational Grid Services.
Highlights
The essence of Grid Computing in enterprises will be realized as a rule rather than as an exception in the near future
The main objective of this study focuses on evolving a virtual supercomputer by aggregating the unused power of the desktop PCs in an enterprise, by developing Grid Services that use Windows-based Grid computing framework called Alchemi (A Grid Services Middleware Developed by GRIDS Lab, University of Melbourne, Australia) as the Grid Engine
Computational Grid can be defined as a hardware and software infrastructure that provides dependable, consistent, pervasive and inexpensive access to highend computational capabilities[1,2]
Summary
The essence of Grid Computing in enterprises will be realized as a rule rather than as an exception in the near future. Grid Computing Infrastructure will support the sharing and coordinated use of resources in dynamic global heterogeneous distributed environments This includes resources that can manage computers, data, telecommunication, network facilities and software applications, provided by different organizations[7]. While deploying a desktop grid the following based open-source Grid tool kit which can be deployed design concepts such as centralized resource in windows based enterprise grid environments It has management, secured data communications, system been developed under Gridbus (www.gridbus.org) efficiency, fault tolerance, system performance and project at Melbourne University, Australia. Alchemi Manager was installed in a desktop (considerably a high end machine) as a windows desktop application and the Alchemi executors were installed in the dispersed locations in the intranet within the different gateways This provides the environment to test the efficiency of the grid jobs and the grid threads transferred among the executor nodes.
