Presentation Transcript

  1. CCIN2P3Site report Wojciech A. Wojcik IN2P3 Computing Center

  2. Services • CPU • Networking • Data storage and access • Data bases • E-mail • WEB • Electronic Documents Managment (EDMS) and CAD • LDAP (OpenLDAP) • MCU • Win2000 domain service

  3. Supported platforms • Supported platforms: • Linux RedHat 7.2  SL3 • Solaris 2.8  Solaris 2.9 • AIX 5.1

  4. Disk space • Need to make the disk storage independent of the operating system. • Disk servers based on: • A3500 from Sun with 3.5 TB • ESS-F20 from IBM with 21.4 TB • ESS from IBM with 5.9 TB • 9960 from Hitachi with 18 TB • FAST900 from IBM with 32 TB (not yet in prod)

  5. Mass storage • Supported medias (all in the STK robots): • DLT4000/7000 • 9840 (Eagles)  9940 (200 GB) • HPSS – local developments: • Interface with RFIO: • API: C, Fortran (via cfio) • API: C++ (iostream) (for g++ and KCC) • bbftp – secure parallel ftp using RFIO interface • Interface with SRB

  6. Mass storage • HPSS • $HPSS_SERVER:/hpss/in2p3.fr/… • HPSS – usage: 645 TB (123 TB in May 2002, 60 TB in Oct 2001). • BaBar – 245 TB • AUGER – 40 TB • EROS II – 32 TB • D0 – 110 TB • Virgo – 13 TB • Other experiments: ATLAS, SNovae, DELPHI, ALICE, PHENIX, CMS

  7. Networking - LAN • Fast Ethernet (100 Mb full duplex) --> to interactive and batch services • Giga Ethernet (1 Gb full duplex) --> to disk servers and Objectivity/DB servers

  8. Networking - WAN • Academic public network “Renater 3”. • Backbone 2.5 Gb • Access USA 2 * 2.5 Gb • CCIN2P3 access 1 Gb Tests give 400 Mb to SLAC 800 Mb to CERN

  9. BAHIA - interactive front-end Based on multi-processors: • Linux (RH72, RH73, SL3 ) -> 16 dual PentiumIII1GHz • Solaris 2.8 -> 2 Ultra-4/E450 • AIX 5.1 -> 2 F40

  10. Batch system - configuration Batch based on BQS (developed at CCIN2P3) • Linux (RH72) -> 652 cpu (PIII) • Linux (RH73/LCG) -> 100 cpu (PIII) • Linux (SL3) -> 68 cpu (PIV) • Solaris 2.8 -> 38 cpu (Ultra60) • AIX 4.3.2 -> 18 cpu (43P-B50)

  11. Support for big experiments • BaBar • Objectivity/DB servers (v.7.1 on Solaris 2.8 and 2.9) • 2 on 440, 8 on Netra-T, 2 on 450, 5 on 480 (common with xrootd) • HPSS with interface to Objectivity (ams/oofs), RFIO and with xrootd – 245 TB (57 TB for root files) • Disk cache for Obj and xrootd – 45 TB (20 TB will be added soon) • SRB for import/export • xrootd is replacing Obj/DB

  12. Support for big experiments • D0 • SAM server (on Linux) • bbftp for import/export with FNAL • Usage of HPSS as SAM cashing space

  13. Present actions • Computing and data storage services for about 45 experiments (HEP, Nuclear Physics, Astro, Bio) • Support Center for EGEE • 10 FTE • ROC – Regional Operation Center • CIC – Core Infrastructure Center • Integration of BQS batch system into LCG

  14. Present actions • LCG for LHC experiments • SRB for BaBar and SNovae (Astro and Bio soon) • xrootd for BaBar and D0

  15. Present actions • Regional Center services for: • EROS II • BaBar ( Tier A) • D0 • AUGER • LHC
