The Worldwide LHC Computing Grid - What? Why? How?Abstract.
2nd talk: The computational and storage capability of the Grid are attracting several research communities. This talk discusses the general patterns observed in supporting new applications and porting them on the EGEE environment. We present the general infrastructure we have developed inside the application and support team at CERN (PSS and GD groups) to merge in a fast and feasible way all these applications inside the Grid, as for example Geant4, HARP, Garfield, UNOSAT or ITU. All these communities have different goals and requirements and the main challenge is the creation of a standard and general software infrastructure for the immersion of these communities onto the Grid. This general infrastructure does effectively "shield" the applications from the details of the Grid (the emphasis here is to run applications developed independently from the Grid middleware). On the other hand, it is stable enough to require few control and support by the members of the Grid team and also of the members of the users communities. Finally, it is flexible and general enough to match the requirements of the different productions without including major changes in the design of the tool.
