The components of a grid infrastructure, toolkit and applications are summarised in this diagram. This is a drastic simplification to get all the information on one page. Each row shows a conceptual level of the system, with basic infrastructure components at the bottom, more general services in the middle and application components at the top. The shading indicates the maturity of the most advanced projects in the area. Drill down for lists of projects related to a component, application area or funding agency.
