  1. Grid Computing Reinhard Bischof ECFA-Meeting March 26th 2004 Innsbruck

  2. Certificate /C=AT/O=UIBK/OU=HEPG/CN=host/grid.uibk.ac.at Where are the files I need ? Which resources are available ? Many, many other clusters Cluster 2 Cluster 1 Master Master Local resource management condor Local resource management PBS PC PC Grid: From local to global resource management Replica Location Service Certificate /C=AT/O=UIBK/OU=HEPG/CN=Nemo Information System (Top) Gatekeeper Information system GridFTP Gatekeeper Information system GridFTP Mapfile C=AT/O=UIBK/OU=HEPG/CN=Nemo .atlas job is executed e.g. as local user atlas003 Storage

  3. Atlas Data Challenge 2 • 3 Grid flavours will be used : • Nordugrid • Sweden (15), Denmark (10), Norway (3), Finland (3), Slovakia (1), Estonia (1) • Nordugrid develops Grid middleware, assists in software deployment, is not dedicated to physics, is not limited to Nordic countries • LHC Computing Grid (LCG) • based on middleware development of DataGrid project • resources in Europe, USA, Taiwan, Japan • goal: first truly world wide grid with 24h/7d/week operation (at least two Grid Operating Centres at two different time zones) • Grid 2003 (US-Project) • 25 sites across USA and South Korea • High Energy Physics Innsbruck: participates in LCG as tier2

  4. LCG LCG-Cluster UIBK-HEPHY Tier2 (under evaluation) LCFG grid02-04 WN grid06 WN UI WN Tier 1 GridKa Karlsruhe supports as primary site HEPHY Innsbruck in installing and testing the LCG-Cluster grid05 SE grid gate grid01 0.6 TB grid

  5. Grid 2003 2736 CPUs http://www.ivdgl.org/grid2003/ Nordugrid 1499 CPUs http://www.nordugrid.org LCG core sites: CNAF,CERN,FNAL,FZK,NIKHEF,PIC-Barcelona,RAL,Taipei 1844 CPUs (~1300 KSI2K) planned for 2Q: 3009 KSI2K http://goc.grid-support.ac.uk

  6. Access for grid users to student‘s PC-labs in Innsbruck during weekends, holidays, whenever they are not needed for teaching • Cooperation between • High Energy Physics group (part of pilot grid project 1) : installation, providing scripts, testing, documentation for users) • Central Information Technology Service (ZID) • Institute of Computer Science 1)Innsbrucker Hochenergie-Grid-Projekt (Federal Ministry for Education, Science and Culture)

  7. ZID-Grid (details) • Strategy: be as flexible as possible • one cluster with adequate size for each group (virtual organization), cluster size can be changed easily (default: one lab = one cluster) • easily change resource management (OpenPBS, Condor or Sun Grid Engine), one configuration file/cluster (add other services) • one timetable/cluster for grid opening hours • One wake up on lan server per location starts the machines of a cluster if the timetable says yes • Status informations of all clusters (ganglia and Globus MDS) are collected by a server (agrid) • Users: High Energy Physics, DPS (Distributed and Parallel Systems, Computer Science), Institute of Structural Analysis (starting next week), ... and members of the AustrianGrid project.

  9. AustrianGridhttp://www.gup.uni-linz.ac.at/austriangrid/ • AustrianGrid project starts April 1st 2004 • initiated by High Energy Physics • Partners in Vienna, Linz, Innsbruck • 1st technical meeting December 4th 2003: • several resources already available via grid • Linz • SCI-Cluster 9 Knoten/18 CPUs, Myrinet Cluster 8 Knoten / 16 CPUs • SGI Altix 3000 128 CPUs, SGI Origin 3800 128 CPUs • Vienna • Cluster Bridge 16*4 CPUs, Cluster Gescher 16 CPUs, other clusters • Innsbruck • ZIDGrid-Cluster (~ 192 CPUs), 14 Cluster • AustrianGrid certification authority in Vienna (L. Lifka VCPC) , needs to be accepted by partners outside Austria (CPS Certificate Practice Statementprepared in Innsbruck, reviewed by partners) • Upcoming activities • information system collecting status of all resources • adding grid gates to more resources
