The edutain@grid portals-providing user interfaces for different kinds of actors

In recent years grid computing has evolved from simple batch processing systems to highly interactive applications. One approach heading in that direction is the edutain@grid project. This project aims to enable the computing power of current grid systems to the area of online computer games and e-learning applications. The shift from traditional scientific computing applications into the domain of business oriented applications has led to the involvement of a variety of actors. All of these organisations and persons have different needs considering the access to the system. To communicate with the edutain@grid system a novel combination of portals had to be developed. Three types of portals allow the stakeholders to get access to this system. These portals allow a unified and consistent interface approach hiding the complexity of traditional grid applications in order to support users from all different fields to work with edutain@grid in an intuitive way.
