  Grid computing is concerned with the sharing and coordinated use of diverse resources in distributed "virtual organizations." The dynamic and multi-institutional nature of these environmentsGrid computing is concerned with the sharing and coordinated use of diverse resources in distributed "virtual organizations." The dynamic and multi-institutional nature of these environments introduces challenging security issues that demand new technical approaches. In particular, one must deal with diverse local mechanisms, support dynamic creation of services, and enable dynamic creation of trust domains. We describe how these issues are addressed in two generations of the Globus Toolkit. First, we review the Globus Toolkit version 2 (GT2) approach; then, we describe new approaches developed to support the Globus Toolkit version 3 (GT3) implementation of the Open Grid Services Architecture, an initiative that is recasting Grid concepts within a service oriented framework based on Web services. GT3's security implementation uses Web services security mechanisms for credential exchange and other purposes, and introduces a tight least-privilege model that avoids the need for any privileged network service.

It introduces a new Grid service called InfoGram that combines the ability of serving as information service and as a job execution service. Previously, both services were architected and implemented within the Globus Toolkit as two different services with different wire protocols. Our service demonstrates a significant simplification of the architecture while treating job submissions and information queries alike. The advantage of our service is that it provides backwards compatibility to existing Grid services, while at the same time providing forwards compatibility to the emerging Web services world. Part of the work conducted within this effort is already reused by the current Open Grid Services Architecture prototype implementation.

  Grids comprise an infrastructure that enables scientists to use a diverse set of distributed remote services and resources as part of complex scientific problem-solving processes. We analyze some ofGrids comprise an infrastructure that enables scientists to use a diverse set of distributed remote services and resources as part of complex scientific problem-solving processes. We analyze some of the challenges involved in deploying software and components transparently in Grids. We report on three practical solutions used by the Globus Project. Lessons learned from this experience lead us to believe that it is necessary to support a variety of software and component deployment strategies. These strategies are based on the hosting environment.

Java CoG Kit middleware isIn this paper we report on the features of the Java Commodity Grid Kit. The Java CoG Kit provides middleware for accessing Grid functionality from the Java framework. Java CoG Kit middleware is general enough to design a variety of advanced Grid applications with quite different user requirements. Access to the Grid is established via Globus protocols, allowing the Java CoG Kit to communicate also with the C Globus reference implementation. Thus, the Java CoG Kit provides Grid developers with the ability to utilize the Grid, as well as numerous additional libraries and frameworks developed by the Java community to enable network, Internet, enterprise, and peer-to peer computing. A variety of projects have successfully used the client libraries of the Java CoG Kit to access Grids driven by the C Globus software. In this paper we also report on the efforts to develop serverside Java CoG Kit components. As part of this research we have implemented a prototype pure Java resource management system that enables one to run Globus jobs on platforms on which a Java virtual machine is supported, including Windows NT machines.

The overall goal of this project is to explore how to enable the development of advanced Grid applications while adhering to state-of-the-art software engineering practices and reusing existing Grid infrastructure. As part of this activity, we are currently investigating how CORBA can be used to support this software engineering task. In this paper, we outline the design of a CORBA Commodity Grid Kit that will provide a software development framework for building a CORBA "Grid domain." We also present our current experiences in developing a prototype CORBA CoG Kit that provides access to the Globus toolkit functionality to support Grid development.

Accessing advanced Grid services, such as authentication, remote accessBuilding Problem Solving environments in the emerging national-scale Computational Grid infrastructure is a challenging task. Accessing advanced Grid services, such as authentication, remote access to computers, resource management, and directory services, is usually not a simple matter for problem solving environment developers. The Commodity Grid project is working to overcome this difficulty by creating what we call Commodity Grid Toolkits (CoG Kits) that define mappings and interfaces between the Grid and particular commodity frameworks familiar to problem solving environment developers. In this paper, we explain why CoG Kits are important for problem solving environment developers, describe the design and implementation of a Java CoG Kit, and use examples to illustrate how CoG Kits can enable new approaches to application development based on the integrated use of commodity and Grid technologies.
