CoreGRID project (NOE): European Research Network on Foundations, SoftwareInfrastructures and Applications for large scale distributed, GRID and Peer-to-Peer Technologies (2004-2008). Sixth Research framework Programme (FP6). Contract No. 004265. Funded by the Commission of European Communities Information Society and Media Directorate-General, the project aims at strengthening and advancing scientific and technological excellence in the area of Grid and Peer-to-Peer technologies. To achieve this objective, the Network brings together a critical mass of well-established researchers (119 permanent researchers and 165 PhD students) from forty-two institutions who have constructed an ambitious joint programme of activities. This joint programme of activity is structured around six complementary research areas that have been selected on the basis of their strategic importance, their research challenges and the recognised European expertise to develop next generation Grid middleware, namely: knowledge & data management; programming models; system architecture; Grid information and monitoring services; resource management and scheduling; problem solving environments; tools and GRID systems.
