gUSE (grid User Support Environment) is a grid virtualization environment providing a scalable set of high-level Grid services by which interoperation between Grids and user communities can be achieved. Incorporating a more flexible workflow concept and enabling its distribution on clusters and different Grid sites, gUSE is aimed to extend the objectives and features of WS-P-GRADE Portal.

WS-PGRADE portal is the second generation P-GRADE portal that introduces many advanced features both at the workflow and architecture level. On the workflow level it extends the workflow concept of P-GRADE with new features.Architecturally, it now explicitly distinguishes between two different types of user communities: application developers and end-users. Through a dedicated view, the application developers have access to all the advanced workflow features (graph, abstract workflow, template, application and project) to develop new workflow applications. The built-in gUSE repository stores the workflow objects published by the application developers, to be downloaded and further developed by the community. The gUSE repository provides a forum for collaboration and enables workflow sharing between application developers. The end-user view enables the download of ready-to-use applications from the repository. The internal workflow structures are not exposed to the end-users, but it gives full access to the parameterization and execution of applications downloaded from the gUSE repository.
