Software work at the French Computing Center (CCF)

The French Computing Center (CCF) is essential for managing vast data requirements of IN2P3. With capabilities for secure storage and rapid extensibility, CCF supports a network of over 45 laboratories, handling multiple terabytes of data. Technologies such as HPSS for storage and BBFTP for fast file transfers ensure efficient data transfer and access. This presentation by Frédéric Fleuret covers the computing capabilities, data handling, tools for muon software, and ongoing collaborations to enhance functionality in particle physics research.

  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
