GRIF, an EGEE site in Paris Region

3. Goals…
Context : EGEE/OSG/NDG grids are the only computing resource for grid experiments
T0 : CERN (15% of total resources)
T1 : long term archival of data, reconstruction
35% of total resources
T2 : simulation + analysis
50% of total resources
GRIF set up as a EGEE distributed site by 6 HEP laboratories in Paris region in 2005
Open to all 4 LHC experiments
80% of french scientists involved in LHC in Paris region
All 6 labs too small to build a significant T2
2 labs (LAL+IRFU) already had a grid experience since 2001
Build a large technical team from people in each lab

4. … Goals
Support non HEP use of grids and provide resources to other communities
Long tradition of resources for biomed and esr at LAL and IRFU
Initially 20% of GRIF resources for non LHC communities, now much more
Patrnetship l’Institut des Systèmes Complexes
Multi-disciplinary research about complexity
Large image processing, modelisation
x2 initial goal in term of CPU resources

5. Resources…
More CPU and storage than initially planned, even though initial objective was ambitious…
Planned 2008 : 3000 kSI2K, 700 TB disk
Today : 5000 kSI2K, 500 TB disk
1 CE and 1 SE operated by each GRIF site
Every CE has an equal access to all SEs (all considered close)
1 internal private network for GRIF, based on 10 Gb/s links
1 10 Gb/s external link to CCIN2P3 (Lyon) for data transfers
Demonstrated 250 MB/s sustained for 1 SE
General purpose services for EGEE
VOMS server : VO membership management
WMS : job submission
MyProxy : proxy renewal server

6. … Resources 1 public UI : grid11.lal.in2p3.fr
Usable by everyone with a grid certificate (and member of an authorized VO, ask if this is not the case)
Give access to the whole grid
VO dedicated to local users for people not member of other VOs
Only GRIF resources are accessible to these VOs
Best effort and opportunistic access to GRIF resources for many VOs
25+ VOs already supported
Ready to open resources to other ones, on demand

7. Organization
Goal : 1 unique grid site and not an administrative group of sites
Scientific committee : strategy and funding
1 representative per GRIF site
Chairman : J.P. Meyer (IRFU)
Technical committee : one of GRIF main asset
20 people representing 10 FTE, from all sites
Every day exchanges, monthly F2F meeting
Responsible : M. Jouvin
1 unique management tool for the whole site to maintain consistency and share management load
1 configuration database for the whole GRIF
Ability to administer GRIF from any site

14. Conclusions GRIF is one of the main EGEE resources
Major contribution to LHC experiment
Significant contribution to other smaller communities and open to support new ones
Communities who participate to funding have a guaranteed access
GRIF demonstrated feasibility of a distributed site build by sharing infrastructures and manpower
Greater global expertise
GRIF is involved in grid usage dissemination
A multi-disciplinary grid is working and is the only path for the future
