  1. Software work at the French Computing Center (CCF) • CCF : The French Computing Center • Phenix @ CCF • LLR @ Phenix @ CCF Frédéric Fleuret LLR-Ecole Polytechnique Phenix Collaboration Meeting Frédéric Fleuret - LLR

  2. French Computing Center (IN2P3) • 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) 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. Frédéric Fleuret - LLR

  3. French Computing Center (IN2P3) • Power : Linux Machines status (12/01) • PCIII Linux 12 machines • 2 proc. / machine (500 MHz) • Memory : 256 MB • PCIII Linux 96 machines • 2 proc. / machine (750 MHz) • Memory : 1024 MB • PCIII Linux 93 machines • 2 proc. / machine (1000 MHz) • Memory : 1024 MB Today 10,000 SpecInt95 Frédéric Fleuret - LLR

  4. 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). 36000 cartridges 400 cartridges 1.3 TB 1.3 TB 7 TB 50 GB Frédéric Fleuret - LLR

  7. Phenix @ CCF • Network traffic @ CCF : • IN (US  CCF) : 1.2 – 2.0 MB/secs. • OUT (CCF  US) : ~1.5 MB/secs. BNL  CCF (~1.2 MB/sec.) CCF  FNAL (~1.5 MB/sec.) SLAC  CCF (~2 MB/sec.) Frédéric Fleuret - LLR

  8. 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 Frédéric Fleuret - LLR

  9. 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 Frédéric Fleuret - LLR

  10. LLR @ Phenix @ CCF Tutorial to run Muon Software @ CCF Tutorial to run Muon Software @ RCF • Tutorials (Raphaël Granier) • 1 tutorial on Muon Reconstruction Code. • 2 tutorials on Phenix Muon Software (based on Yajun Mao Tutorial). Frédéric Fleuret - LLR

  11. 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.
