French Computing Center (IN2P3)
The IN2P3 Computing Centre was created to meet the needs of these laboratories. This centre must be capable of making readily available a very large amount of data (several hundred terabytes) in a secure manner, distributed between disks and tapes managed by robots. Computing power must be rapidly extensible and data access must be as transparent as possible.
• The Institute
• IN2P3 computing center
IN2P3 =Institut National de Physique Nucleaire et de Physique des Particles = Institute of the CNRS (~26000 people, 12000 scientists) American NSF ~ 3300 people, 1700 permanent scientists = 18 laboratories + 1 Computing Center (~45 people)

French Computing Center (IN2P3)• File Storage :
– HPSS :• 36000 Cartridges• 6 Cartridge Mounting silos• Capacity : 720 TB on line
• File Transfer :– BBFTP is a software designed to quickly transfer files
accross a wide area network. It has been written for the babar experiment in order to transfer big files (more than 2 GigaBytes) between SLAC (California) and the
In2p3 Computing Center (Lyon,France).

LLR @ Phenix @ CCF
• The « guru » : Albert Romana
• Code implementation– Run complete simulation/reconstruction chain,
both interactively and on batch @ CCF.
• Code development– Database for file storage @ CCF
– Tutorials & script to run phenix code (run_phnx)
– Start working on nanoDSTs for muons
July 2002 Frédéric Fleuret - LLR
LLR @ Phenix @ CCF
• HPSS database @ CCF (Albert Romana)
• Get information about files stored in HPSS
• Updated automatically when storing files in HPSS
• Accessible on the web
• Ready to store files (in HPSS) @ CCF
July 2002 Frédéric Fleuret - LLR
LLR @ Phenix @ CCF• Tutorials (Raphaël Granier)
– 1 tutorial on Muon Reconstruction Code.
– 2 tutorials on Phenix Muon Software (based on Yajun Mao Tutorial).
Tutorial to runMuon Software @ CCF
Tutorial to runMuon Software @ RCF

LLR @ Phenix @ CCF
• run_phnx (Albert)– Run any of the PHENIX programs :
• genp (Pythia), genh (Hijing)
• pisa, resp
• reco, dst
– Syntax : run_phnx genp 1000
– By default, uses the scripts, macros and files installed
by Raphael in his tutorial.
– Allows to execute programs either interactively or by
batch.
– Upgrade version : use java and create panels to run
run_phnx.
