  2. What specific problem is the Globus Toolkitdesigned to address?

  3. Ultimately, the Globus Toolkit is designed to enable the creation and maintenance of Virtual Organizations

  4. Virtual Organizations • Distributed resources and people • Linked by networks, crossing admin domains • Sharing resources, common goals • Dynamic • Fault tolerant R R R R R R R R R R R R VO-A VO-B

  5. Layers in the Grid

  6. The Globus Toolkit:“Standard Plumbing” for the Grid • Not turnkey solutions, but building blocks & tools for application developers & system integrators • Some components (e.g., file transfer) go farther than others (e.g., remote job submission) toward end-user relevance • Easier to reuse than to reinvent • Compatibility with other Grid systems comes for free • Today the majority of the GT public interfaces are usable by application developers and system integrators • Relatively few end-user interfaces • In general, not intended for direct use by end users (scientists, engineers, marketing specialists)

  10. The Globus Toolkit is a Collection of Components • A set of loosely-coupled components, with: • Services and clients • Libraries • Development tools • GT components are used to build Grid-based applications and services • GT can be viewed as a Grid SDK • GT components can be categorized across two different dimensions • By broad domain area • By protocol support

  16. Summary • The Globus Toolkit is a collection of reuseable components to help application builders harness the Grid • In OMII-Europe, the challenge is to allow components from different middleware stacks to interact and interoperate well • For Globus, the main areas are: • Job Submission • Data Services • Accounting and Security
