5. Computing at HEPHY 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 5Natascha Hörmann11 November 2010

6. Computing at HEPHY 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) 6Natascha Hörmann11 November 2010

7. Computing at HEPHY Resources at the HEPHY Grid computing center 7Natascha Hörmann11 November 2010 Available: 1000 CPUs, 500 TB disks 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 ? Computer: Sun 2x4 Core, Intel Xenon 2.5 GHz Storage: Supermicro RAID, DataPool Manager (DPM) Operating System: SLC5

9. Computing at HEPHY Data transfer at the Tier-2 @ HEPHY 9Natascha Hörmann 11 November 2010 Outgoing transfer – Vienna –> Tier-1/2s Incoming transfer – Tier-1/2s –>Vienna 22.9 MB/sec 10.5 MB/sec 30 25 20 15 10 5 0 100 80 60 40 20 0 MegaByte/sec days  Average transfer of about 2 TByte/day incoming and 1 TByte/day outgoing data

10. Computing at HEPHY Grid infrastructure for scientific groups 10Natascha Hörmann11 November 2010 Tier-2 HEPHY* High Energy Physics - CMS SUSY Quarkonia b-Tagging High Energy Physics - CMS SUSY Quarkonia b-Tagging Theory CP violation High Energy Physics Belle II Current Projects Future Projects * Federated Tier-2 together with the University of Innsbruck Medical Application Hadron tumor therapy studies Stefan-Meyer Institute Panda at FAIR

11. Computing at HEPHY 11Natascha Hörmann11 November 2010 Hadron tumor therapy studies using Grid@HEPHY Results submitted to Z. Med. Phys.  Cooperation with Medical University of Vienna in connection with the radiation therapy center MedAustron in 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

12. Computing at HEPHY 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) and b-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 and Quarkonia analysis  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 12Natascha Hörmann11 November 2010

13. Computing at HEPHY HEPHY CMS Center  Commissioned to run general shifts for the CMS experiment in Vienna (saves travel costs) 13Natascha Hörmann11 November 2010

14. Computing at HEPHY Future requirements  LHC computing requirements for the next years  until 2012: an increase of 60 % CPUs and 100 % disk space is needed  we assume replacement of equipment with constant budget (with the typical increase of performance every year) 14Natascha Hörmann11 November 2010 ICHEP2010, 28 Jul. 2010, Paris, Progress in Computing, Ian Bird Expected needs in 2011 & 2012 CPU Disk

15. Computing at HEPHY Future Austrian Computing Landscape 15Natascha Hörmann11 November 2010  Vienna Scientific Cluster (VSC)  will host our Tier-2 computing center through our connections to the Vienna UT  the installation with new equipment is planned to start in 2012 at the VSC location (technical stop of LHC); provided funding is secured  Austrian Center for Scientific Computing (ACSC)  initiative from several universities  is a common framework for computing cooperation between institutes in Austria and abroad  HEPHY intends to be part of ACSC via VSC

16. Computing at HEPHY Summary & Outlook  The HEPHY Grid computing center is smoothly running and allows us to participate in the analysis of data in the first row  important for our physics analysis  important for our position in the CMS 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 16Natascha Hörmann11 November 2010
