  1. Computing at HEPHY Natascha Hörmann Evaluation 2010

  2. Overview • Computing group at HEPHY • The Vienna Grid computing center • Future plans Natascha Hörmann

  3. Mission • Provide infrastructure and support for general computing • Operate and maintain a highly available and powerfulGrid computing center Natascha Hörmann

  4. Computing Group • Leader: G. Walzel • Group: S. Fichtinger, U. Kwapil, D. Liko, N. Hörmann, B. Wimmer • General computing: 3.0 FTEGrid effort: 2.5 FTE Natascha Hörmann

  5. Tasks of the Computing group • Run the HEPHY computer infrastructure • general tasks (Network, Mail, Printer), Windows/Mac/Linux desktops, internet services, application server, file system services (AFS, NFS)… • Belle, Theory and CMS interactiv computing facility Natascha Hörmann

  6. Tasks of the Computing group • Provide the infrastructure for the worldwide distributed Grid computing as a Tier-2 center • computing power and storage for the CMS experiment • essential computing resource for our physics analysis groups at HEPHY • resources also for other applications (e.g. non HEP) Natascha Hörmann

  7. Resources at the HEPHY Grid computing center • Available: 1000 CPUs, 500 TB disks Computer: Sun 2x4 Core, Intel Xenon 2.5 GHz Storage: Supermicro RAID, DataPool Manager (DPM) Operating System: SLC5 • Presently operated: 730 CPUs, 320 TB disks • ? • In 2010 the Academy has decided to charge the costs for electricity to our institute (15 % of the institute material budget); for budget reasons we operate only ⅔ of the equipment • The current hardware is four years old and has to be replaced starting 2012; funding is required but not yet secured Natascha Hörmann

  8. The Grid Tier-2 @ HEPHY • Tier-2 @ HEPHY provides 2 %of overallCMS Tier-2 capacity • Average availability is 98 % • among the best sites • About2.400 Jobs/day • HEPHY • 6.000 • 5.000 • 4.000 • 3.000 • 2.000 • 1.000 • 0 • Jobs • 2.400 Jobs/day • Analysis • MC simulation • Job-Robot • days Natascha Hörmann

  9. Data transfer at the Tier-2 @ HEPHY • Outgoing transfer – Vienna–> Tier-1/2s • Incoming transfer – Tier-1/2s –>Vienna • Averagetransfer of about2 TByte/dayincoming and1 TByte/dayoutgoingdata • 30 • 25 • 20 • 15 • 10 • 5 • 0 • 100 • 80 • 60 • 40 • 20 • 0 • 10.5 MB/sec • MegaByte/sec • 22.9 MB/sec • days • days Natascha Hörmann

  10. Grid infrastructure for scientific groups • Current Projects • Future Projects High Energy Physics - CMSSUSY Quarkonia b-Tagging Stefan-Meyer Institute Panda at FAIR Tier-2 HEPHY* TheoryCP violation High Energy PhysicsBelle II Medical ApplicationHadron tumor therapy studies * Federated Tier-2 together with the University of Innsbruck Natascha Hörmann

  11. Hadron tumor therapy studies using Grid@HEPHY • Cooperation withMedical University of Vienna inconnection with the radiation therapy center MedAustronin Wiener Neustadt • Simulation studies of energy deposition in material with heavy charged particles like protons or carbon/helium ions looking especially at the fractional tail Results submitted to Z. Med. Phys. Natascha Hörmann

  12. Advantages of running a Tier-2 @ HEPHY • Grid computing site for CMS physics groups • selected as one of the computing cluster for SUSY (1 of 5)andb-tagging (1 of 4) • the relevant datasets of these groups are stored and the analysis jobs are executed at our site • Infrastructure for our local physics analysis group • direct access to resources enhances successful contributions from HEPHY physics groups to SUSY, b-tagging andQuarkoniaanalysis • enough storage is available to store our own analysis results • control the usage of the computing power and storage in case of important findings or necessary resources for conference Natascha Hörmann

  13. HEPHY CMS Center • Commissioned to run general shifts for the CMS experiment in Vienna (saves travel costs) Natascha Hörmann

  14. Future requirements • LHC computing requirements for the next years • until 2012: an increase of 60 % CPUs and 100 % disk space is needed • weassumereplacement of equipmentwithconstantbudget(withthetypicalincrease of performanceeveryyear) Expected needs in 2011 & 2012 • CPU • Disk • ICHEP2010, 28 Jul. 2010, Paris, Progress in Computing, Ian Bird Natascha Hörmann

  15. Future AustrianComputing Landscape • Vienna Scientific Cluster (VSC) • will hostour Tier-2 computingcenterthroughourconnections to the Vienna UT • theinstallationwithnewequipmentisplanned to start in 2012 at the VSC location (technical stop of LHC); providedfundingissecured • Austrian Center forScientificComputing(ACSC) • initiative fromseveraluniversities • is a commonframeworkforcomputingcooperationbetweeninstitutes in Austria and abroad • HEPHY intends to bepart of ACSC via VSC Natascha Hörmann

  16. Summary & Outlook • The HEPHY Grid computing center is smoothly running and allows us to participate in the analysis of data in the first row • importantforourphysicsanalysis • importantforourpositionin theCMS collaboration • Funding of the Grid Tier-2 upgrade by replacement of the hardware needs to be secured • HEPHY plans to install the new equipment of the Grid computing center at the Vienna Scientific Cluster (VSC) in 2012 • HEPHY intends to participate in the Austrian Center for Scientific Computing (ACSC) which is important for our future computing interests Natascha Hörmann
