Prof. Wolfgang Gentzsch D-Grid Coordinator "Impact of D-Grid on Science & Industry in Germany" Globalization demands global infrastructures, e.g. for transportation, communication, collaboration. Collaboration will be facilitated by grid infrastructures, which are currently being built in hundreds of grid projects around the world. The 5-year German D-Grid initiative aims at developing a common grid infrastructure for "Services for Scientists", to be tested by Community Grids (high-energy physics, astronomy, climate, medicine, engineering, libraries). Recently, a 2nd Call invited new communities and IT service providers to help expand the user community, and to strengthen D-Grid towards a productive and sustainable service platform. This lecture will highlight D-Grid, and its challenges and benefits for the national and international science and industry community.
