Design and Implementation of EZ-Grid Information Server

EZ-Grid is a stand-alone Java Swing-based graphical user interface for use in a Grid environment. It is designed to act as a high-level job submission tool that utilizes Globus toolkit to achieve Grid tasks. EZ-Grid contains a broker system or a grid metascheduler that identifies suitable resources to submit grid jobs. Information about status of grid resources is vital to make correct scheduling decisions. Current grid-based information systems fall short in providing all the information required by the EZ-Grid broker. Any grid information provider does not provide information on queues or other dynamic attributes of a remote resource. EZ-Grid information system is designed to complement these existing information systems by acting as a new source for information. It is currently designed store and retrieve information such as grid job submission history, dynamic and static resource information and applications on the remote resource. Information is stored as XML files to mimic a directory information tree structure. Apart from acting as an information provider, EZ-Grid system also offers a grid resource discovery service, wherein active information servers are located in real-time.
