Title: Farming in France CCIN2P3


1
Farming in France CC-IN2P3
  • GRID Technical Workshop
  • 4 septembre 2000
  • Denis Linglin
  • linglin_at_in2p3.fr

2
HEP computing in France
  • 15-18 labs PPNPAstro, each with local servers
    and PCs.
  • One single computing centre CC-IN2P3
  • Lyon, 40 people (30 comp. scientists), 10 MCHF
    /year
  • Computing, Storage, Networks, Support
  • serving IN2P3DAPNIA/CEA
  • CC-IN2P3 RC or Tier1 for all large HEP
    experiments where France is involved.
  • will host most EU funded support for DataGrid in
    F.

Computing power by platform
5
Basic software components
  • Data access AFS, Xtage, HPSS, RFIO
  • Batch cluster management BQS
  • Batch queing system
  • Directory services RPCLOC, NIS, LDAP
  • RPC (remote procedure call) servers localisation
    (localises other services like BQS, Xtage,
    PrivMan, RFIOD, etc)
  • Network Information Services (ex Yellow Pages),
    distrib. of machines and users
  • LDAP Lightweight directory access protocol
    (hierarc
  • Authentication and Privilege management
  • Authentication IN2P3, Based on standard Ident
    protocol
  • PM IN2P3, data base of privilege per user,
    group, host and applications

6
Users
  • HEP, Astroparticle, NP Simulation and analysis
    of particle and nuclear physics events. 20 main
    experiments
  • International collaborations are the rule.
  • "Regional Centre" for several expts.
  • Single threaded jobs, no parallelism (so far)

7
Future
  • Previsions for 2001/2002
  • Virgo parallel computing, 1Tflops (IBM/SP2 6
    nodes 32 ways Power IV).
  • Babar 50 SUNs Ultra60 (migrating to LINUX).
  • D0 200 PC/LINUX.
  • AUGER 140 PC bi-pro at 450 Mhz.
  • LHC CPUx100, Diskx50, Tapex10 before 2006
