CERN where the web was born

• Fundamental scientific challenges
• produce new information technologies

The next fundamental
challenge LHC the Large Hadron
Collider Worlds largest
superconducting
structure 27 Km of magnetswith a field of 8.4
Tesla Super-fluid Heliumcooled to 1.9K Two
counter-circulating proton beams Collision
energy 14 TeV

LCG The LHC Computing Grid Project

• a geographically distributed computing facility
• for a very large user population of
  independently-minded scientists
• with independent ownership/management of the
  different nodes
• each with different access and usage policies
• and serving multiple user communities

10
LCG The LHC Computing Grid Project

• If this challenge can be solved for High Energy
  Physics,
• it can be applied far more widely
• Collaborations between national and international
  organisations (disaster relief, disease
  prevention, etc)
• Collaboration between companies and academia
  
  (complex engineering design, drug discovery etc)

The European DataGrid project

• Largest EU funded software development project
  ever
• 6 main contractors, 15 assistant contractors
• 9.8 millions funded by EU with substantial
  co-funding
• 150 Full Time Equivalent over 3 years
• Flagship project of the EU IST GRID program
• Project started Jan 2001, duration 3 years

15
The European DataGrid project

• The DataGrid Project tackles three challenging
  scientific applications
• High Energy Physics
• process the huge amount of data from LHC
  experimentations
• Biology and Medical Imaging
• sharing of genomic databases for the benefit of
  international cooperation
• processing of medical images for medical
  collaborations
• Earth Observations
• access and analysis of atmospheric ozone data
  collected by satellites such as Envisat-1

Conclusion

• Needs of High Energy Physics create new
  technologies.
• - The Grid is a new Information Technology.
• Grid technologies aim to pool global computing
  resources.
• - address needs of complex, distributed
  communities.
• Grid technologies are being developed world-wide.
• - requires major public investment before the
• technology is mature enough for
  commercialisation.
