1. European DataGrid Project status and plans Peter Kunszt, CERN DataGrid, WP2 Manager Peter.Kunszt@cern.ch

2. Outline EU DataGrid Project • EDG overview • Project Organisation • Objectives • Current Status overall and by WP • Plans for next releases and testbed 2 • Conclusions

3. The Grid vision • Flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resource • From “The Anatomy of the Grid: Enabling Scalable Virtual Organizations” • Enable communities (“virtual organizations”) to share geographically distributed resources as they pursue common goals -- assuming the absence of… • central location, • central control, • omniscience, • existing trust relationships.

4. Grids: Elements of the Problem • Resource sharing • Computers, storage, sensors, networks, … • Sharing always conditional: issues of trust, policy, negotiation, payment, … • Coordinated problem solving • Beyond client-server: distributed data analysis, computation, collaboration, … • Dynamic, multi-institutional virtual orgs • Community overlays on classic org structures • Large or small, static or dynamic

5. EU DataGrid Project Objectives • DataGrid is a project funded by European Union whose objective is to exploit and build the next generation computing infrastructure providing intensive computation and analysis of shared large-scale databases. • Enable data intensive sciences by providing world wide Grid test beds to large distributed scientific organisations ( “Virtual Organisations, VO”) • Start ( Kick off ) : Jan 1, 2001 End : Dec 31, 2003 • Applications/End Users Communities : HEP, Earth Observation, Biology • Specific Project Objetives: • Middleware for fabric & grid management • Large scale testbed • Production quality demonstrations • To collaborate with and complement other European and US projects • Contribute to Open Standards and international bodies ( GGF, Industry&Research forum)
