Following the 7th IDGF tutorial and workshop at EGI UF in Vilnius which had its main focus on applications, we now propose a session that focuses more on the infrastructure. How can you connect Desktop Grids into EGI infrastructures? We will show howto's for gLite, based on long time experiences. In addition the EDGI project, the organiser of this session has also built a bridge between Arc-based Grids and Desktop grids. First results and experiences will be reported.
