Title: Site report: CERN


1
Site report CERN
  • Helge Meinhard (at) cern ch
  • HEPiX fall 2005 _at_ 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

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

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 (gt 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
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
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

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

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_at_home Beam orbit simulation
  • CERN screen saver being deployed to all Windows
    clients at CERN
  • BOINC added O (100) dual processor machines
    with lt 1 GHz PIII
  • AIS applications migrating to Linux servers

Talk
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 -gt E-mail gateway
  • Moving out of roaming profiles
  • Pilot to run xp without admin privileges
  • PXE-based install now default (no media)

10
Communication Systems
  • IPX/Novell and Appletalk routing switched off

11
User and Document Support
  • InDiCo taking over from CDS Agenda
  • Desktop PC procurement and sales streamlined
  • CERN stores getting more involved

Talk
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

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
