  1. Infrastructure overview Arnold Meijster & Fokke Dijkstra, RC/RuG Grid Tutorial, Groningen, 18&19 September 2006

  2. Overview National and international grid infrastructures • EGEE • NL Grid • VL-e • Deisa • BIG grid (future) Grid Tutorial - Groningen September 2006

  3. EGEE • EU project for worldwide Grid • Operational infrastructure • Support for sites and users • Monitoring • Multiple VOs • Many scientific communities • VOs start locally and can grow worldwide • gLite middleware • EGEE organised in multiple regions Grid Tutorial - Groningen September 2006

  4. EGEE Grid Tutorial - Groningen September 2006

  5. EGEE (europe) 177 sites 27759 CPUs 44 PB Storage Grid Tutorial - Groningen September 2006

  6. EGEE live! • http://gridportal.hep.ph.ic.ac.uk/rtm/applet.html Grid Tutorial - Groningen September 2006

  7. Quality Assurance • Site Functional tests • Operated several times a day • Status page: https://lcg-sft.cern.ch/sft/lastreport.cgi(need certificate in browser) Grid Tutorial - Groningen September 2006

  8. Support • Regional support model • Multiple regions in Europe • For support in Northern Region(NL,BE,SE,DK,NO,FI) mail to: support@egee-ne.org Grid Tutorial - Groningen September 2006

  9. LHC tiering model • Large Hadron Collider starts in 2007 • Petabytes of data! • Huge computational demand • Tiering model for distribution of data • CERN Tier0 • Several Tier1 sites, including Nikhef/SARA • Many Tier2 sites • Computation near data Grid Tutorial - Groningen September 2006

  10. Tier model Grid Tutorial - Groningen September 2006

  11. NL-Grid • National infrastructure • Clusters at Nikhef,Sara and RuG • Currently about 400 cpus • Lisa cluster Sara (1500 cpus) also available • Special bioinformatics clusters to be installed at several sites • DAS-3 research clusters Grid Tutorial - Groningen September 2006

  12. NL-Grid storage • Storage coupled to clusters at Nikhef and SARA • Several Terabytes • Tape storage at SARA coupled to grid • Disk pool in front • Tape storage coupled via SAN • Multiple petabytes and growing! • In near future all storage will support the Storage Resource Management (SRM) interface • San Diego Storage Resource Broker (SRB) also available at Sara Grid Tutorial - Groningen September 2006

  13. VL-e • Mission: To boost e-Science by creating an e-Science environment and carrying out research on methodologies. Grid Tutorial - Groningen September 2006

  14. Deisa • European super-computing grid • Shared global file system • Job migration • Co-scheduling Grid Tutorial - Groningen September 2006

  15. Big Grid • Improving the national grid infrastructure • Large grant ~30 million euro • Goals of: • 27,600 kSI2k in 2009 (~35,000 high end PC’s) • 14.1 Petabytes of storage in 2009 • Support many scientific disciplines: • Astronomy, Biological & medical sciences,High energy physics, Linguistics,Climate research Grid Tutorial - Groningen September 2006

  16. Conclusions • Many projects! • What should I do?? • Go to your nearest expert site and ask for help • What are your demands? • Computing • Storage • Other, e.g. real-time access • Collaborate! • National • With other people all over the world • Start a VO Grid Tutorial - Groningen September 2006
