GRIF is a distributed Tier2/Tier3 (6 sites in the Paris region)
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.

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

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 Ecole Polytechnique (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)

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
