The GRIF project

The GRIF project. GRIF is a distributed Tier2/Tier3 (6 sites in the Paris region). 10 Gbit /s WAN (RENATER). The project started in 2005 with the main goal of building a federated LCG Tier2 grid infrastructure but also cover computing needs of other fields.

  3. GRIF is a distributed Tier2/Tier3 (6 sites in the Paris region) 10 Gbit/s WAN (RENATER) The project started in 2005 with the main goal of building a federated LCG Tier2 grid infrastructure but also cover computing needs of other fields. J-P Meyer

  4. Around 40 supported virtual organizations J-P Meyer

  5. GRIF by numbers 10Gbit/s link between sites and CCIN2P3 70% Tier2 30% Tier3+other VO Including working 5 years old CPU’s A common technical team of 20 peoples (12 FTE’s) Around 200 users (170 form LHC experiments) J-P Meyer

  6. FR- Accounting ALL VO 28% LHC VO 27% J-P Meyer

  7. 21% J-P Meyer

  8. GRIF - Accounting ~85% LHC J-P Meyer

  9. LCG-View LCG availability % % LCG Accounting J-P Meyer

  10. ATLAS view (1/2) (last 12 months) 23% 9050 HS06 and 1600TB DPM based storage J-P Meyer

  18. Perspectives • New RENATER POP at CEA with double 10Gbit/s connection to RENATER •  10Gbit/s direct connection to LHCONE+INTERNET •  IRFU should become soon T2D J-P Meyer

  21. Perspectives • Tests with GPU’s at LLR (GRIDcl project) • manly devoted to ALICE and CMS heavy ion reconstruction but could • also benefit to ATLAS if people interested… • Project of upgrade of the computing rooms: • At EcolePolytechnique (LLR) •  installation of new water cooled racks • At Orsay (IPNO, LAL) •  building of a new extendable common computing room •  phase 1  100m2 and 400kW of power (electricity and cooling) J-P Meyer

  22. Conclusions • GRIF is a distributed grid node including a shared Tier2/Tier3 for the 4 LHC VO’s. • GRIF is serving around 200 local users  reactivity and flexibility to user problems (proximity) • Major advantages of such a configuration are: • Redundancy of resources  robustness of access to resources for the users • A shared technical team  robustness of the services, common share of technical tasks (solidarity) • Visibility in terms of offered resources J-P Meyer
