  1. Site report: CERN Helge Meinhard (at) cern ch HEPiX fall 2005 @ SLAC

  2. Re-organisation (01-Nov-2005) • This time, the physics services part of IT: • GD (Grid Deployment) and GM (Grid Middleware) merge (I. Bird) • Physics Services Support (J. Knobloch): Physics Database Services (now in ADC), Experiment Integration Support and ARDA (now in GD) • Linux expertise and AFS section (now in ADC) joins FIO (T. Cass) • Openlab section (now ADC) moves to DI • Bernd Panzer moves to LCG • Jamie Shiers to lead a coordination team for development of LHC computing services across regional centres CERN site report – Helge Meinhard

  3. Personnel changes • John Ferguson (deputy department head) left IT on 30-Jun-2005 • Frédéric Hemmer to become deputy department head on 01-Nov-2005 • Les Robertson acting ad interim CERN site report – Helge Meinhard

  4. Fabric Infrastructure and Operations (1) • RedHat 7.3 phased out on public services • Campaign on storage nodes far advanced • New in machine room since Karlsruhe: • 200 farm PCs (dual Nocona): in production • 116 disk servers (> 5 TB usable each, total of 900 TB gross capacity): part in production, part under acceptance test • 112 “midrange servers”: under acceptance test • 32-node Infiniband-based cluster for Theory • Refurbishment of machine room proceeding • LHS being populated, but power remains limited Talk CERN site report – Helge Meinhard

  5. Fabric Infrastructure and Operations (2) • June/July: Large number of nodes given to Atlas DAQ for tests • Peak: 730 dual-CPU machines • Another stress test for Quattor: successful • Castor 2 being deployed • Very close feedback loop with developers • Aim is to migrate Atlas and CMS by 01/2006 • Lemon monitoring: brushed up for installations outside CERN Talk CERN site report – Helge Meinhard

  6. Fabric Infrastructure and Operations (3) • Seeing new generation tape drives • 6 LTO-3 in a new STK silo • High-end STK and IBM drives • Serial console largely deployed • Still some software issues to address • Using SMART test to identify iffy disks • Batch updates Talk al Talk CERN site report – Helge Meinhard

  7. Architecture and Data Challenges • OpenLab at the end of first 3 y period • Continuation being clarified • Test version of SLC4 released • No deployment planned on public services • Interest for service nodes (storage) • Certification started • Data bases for physics: RAC clusters in production Talk Talk CERN site report – Helge Meinhard

  8. Database and Engineering Services • Sundev discontinued on 01 July 2005 • Solaris no longer a physics platform at CERN • RARP switched off • Software licences managed coherently • LHC@home: Beam orbit simulation • CERN screen saver – being deployed to all Windows clients at CERN • BOINC – added O (100) dual processor machines with < 1 GHz PIII • AIS applications migrating to Linux servers Talk CERN site report – Helge Meinhard

  9. Internet services • Single sign-on coming • All centrally managed services at CERN • Windows terminal server popular • Good thing in terms of security • New fax service with fax -> E-mail gateway • Moving out of roaming profiles • Pilot to run xp without admin privileges • PXE-based install now default (no media) Talk Talk CERN site report – Helge Meinhard

  10. Communication Systems • IPX/Novell and Appletalk routing switched off CERN site report – Helge Meinhard

  11. User and Document Support • InDiCo taking over from CDS Agenda • Desktop PC procurement and sales streamlined • CERN stores getting more involved Talk CERN site report – Helge Meinhard

  12. Computer Security • IRC and P2P applications banned • Positive effect very visible • VPN most important route of malware into CERN • Actively being discouraged • Some viruses simply faster than the antivirus update CERN site report – Helge Meinhard

  13. Miscellaneous • CERN School of Computing 04 – 17 September in St. Malo / France very successful • LCG TDR as well as Computing TDRs of LHC experiments submitted • Proposal for EGEE Phase II submitted CERN site report – Helge Meinhard
