  1. The LHC Computing Grid Project Tomi Kauppi Timo Larjo

  2. LHC • Large Hadron Collider • World’s most powerful particle accelerator • Constructed at CERN

  3. LHC Properties • 24 Km of magnets with a field of 8.4 Tesla • Super-fluid helium cooled to 1.9 degrees of Kelvin • Two counter-circulating proton beams • Collision energy 7+7 TeV

  4. LHC Computing Grid Project • The goal is to deploy a worldwide computational grid service • Will cover computing centers spread across Europe, Asia and America.

  5. Grid Project Challenges • Evolving technologies • Changing requirements • US-Europe compatibility in Grid technology • Funding sources

  6. Funding • CERN base budget • Special contributions of people and materials • Industrial collaboration • National funding of computing services at regional centres

  7. Why Use Grid for This Project • LHC will produce huge amount of data • The user community and computing facilities are globally distributed • different access and usage policies.

  8. Why Use Grid for This Project

  9. Why Use Grid for This Project • Wide area distributed data management • Efficient resource scheduling • Security • Performance and status monitoring • Reliability and sustained throughput • Efficient use of high throughput wide area networks

  10. The Project Overview • application support and coordination • computing systems • Grid technology • Grid deployment

  11. How is the Grid planned to work

  12. Possible software choices • GLOBUS: X509 certificates, GSI Authentication, GridFTP, MDS LDAP based monitoring and resource discovery framework, GRAM job submission; Replica services. • Authorization extensions: LDAP VO service

  13. Possible software choices • CONDOR: Condor-G job scheduling, matchmaking (classads), dependencies dagman. • File Movement and Storage Management: GDMP, GridFTP, SRM

  14. Technology Projects And Organizations Involved • DataGrid • CrossGrid • DataTAG

  15. Technology Projects And Organizations Involved • GridPP (UK) • INFN Grid • Dutch Grid, • NorduGrid • Hungarian Grid

  16. Technology Projects And Organizations Involved • GriPhyN • PPDG • iVDGL
