3. Paula Eerola Lunarc, 19.4.2002 3 High Energy Physics Computing  High Throughput Computing  Data consists of independent events  Computing in parallel – not parallel computing  Use inexpensive mass market components  Use nationally available resources  Need inexpensive, distributed, scalable system  GRID  A fully operational GRID-system has to work when the Large Hadron Collider, LHC, starts in 2007

4. Paula Eerola Lunarc, 19.4.2002 4 Computing Model for LHC data processing Data Grid concept in high energy physics applications

5. Paula Eerola Lunarc, 19.4.2002 5 What is Grid?  A technology to join together computers at different locations, and to provide easy access to this capacity.  User can get access to computer capacity anywhere in the Grid.  World-wide-web  access to information  World-wide-grid  access to PC capacity  Initiated in the end-90’s in the US by physicists who wanted to connect together the US supercomputer centers.  Ian Foster, Carl Kesselman, July, 1998: The GRID; Blueprint for a new Computing Infrastructure

6. Paula Eerola Lunarc, 19.4.2002 6 Who are interested in Grid?  All areas of basic research which deal with large amounts of data and/or large computing requirements, for example biomedicine, earth sciences, space/astrophysics, particle physics, etc.  All areas of applied research which deal with large amounts of data and/or large computing requirements, for example analysis of financial markets, industrial process optimization, industrial design, etc.

7. Paula Eerola Lunarc, 19.4.2002 7 Who are interested in Grid?  Huge commercial interests: film animation, electronic commerce etc.  IBM, Sun, Compaq, Platform Computing are some of the companies which have joined the Grid development  IBM: Grid-enable the company’s entire product portfolio. Close cooperation with the open source Globus development.  Platform Computing: Recently acnnouned the first commercial Grid software, the Platform Globus.

8. Paula Eerola Lunarc, 19.4.2002 8 Swedish HEP Grid activities  March 2000 Lund workshop: first discussion on using Grid for basic research in particle physics  During 2000: CERN-EU DataGrid and Nordic NorduGrid projects are formed. Lund group (Elementary Particle Physics, EPF, at the Lund University) active in both projects.  Testbeds: building, testing and developing Grid in the framework of DataGrid and NorduGrid. Generic research in Grid- systems.

9. Paula Eerola Lunarc, 19.4.2002 9 NorduGrid NorduGrid – NordicTestbed for Wide area Computing and Data Handling www.nordugrid.org The pioneering Grid project in the Nordic countries

10. Paula Eerola Lunarc, 19.4.2002 10 NorduGrid objectives  Introduce the Grid to the Nordic countries  Create a Grid infrastructure in Nordic countries  Survey and develope current Grid technologies  Operate a functional Testbed  Expose the infrastructure to end- users of different scientific communities Sites: Lund, Copenhagen, Oslo, Bergen, Uppsala, Stockholm, Helsinki

11. Paula Eerola Lunarc, 19.4.2002 11 NorduGrid project  The project was initiated by the Nordic High Energy Physics community –LHC data challenge of CERN (several Petabytes / year) –Operates as part of the CERN-EU DataGrid Testbed –Physicists are among the driving forces of the World Wide Grid developement  The project is financed via the Nordunet2 programme. Project duration Jan 2001 - Nov 2002.  Continued NorduGrid is being planned under NOS-N.

12. Paula Eerola Lunarc, 19.4.2002 12 NorduGrid progress  Hardware: dedicated test clusters at 5 sites (3-5 machines), separate test machines at 2 sites: 7 Grid-connected sites  Manpower: 5 full time researchers (O. Smirnova & B.Kónya Lund, A. Wäänänen Copenhagen, M. Ellert Uppsala, A. Konstantinov Oslo)  Design and implementation of the NorduGrid Middleware Architecture  Deployment & evaluation of the first release of the CERN-EU DataGrid Middleware (Information index, Job submission interface, Broker)

13. Paula Eerola Lunarc, 19.4.2002 13 NorduGrid status April 2002  Grid-services which are now fully functional:  Certification Authority,  NorduGrid Information System browser Information System browser  NorduGrid Virtual Organization,Virtual Organization  Grid Data Mirroring Package GDMP and Data Replication CatalogGDMP and Data Replication Catalog  GridFTP.  Stable software releases and documentation  Based on the Globus Toolkit™  A new jobmanager is written  A User Interface is added  The appropriate information schema is deployed  Extensions to the Globus Resource Specification Language are made  March 28, 2002: first REAL job is submitted from Lund to Oslo and successfully returned all the expected output

14. Paula Eerola Lunarc, 19.4.2002 14 CERN-EU DataGrid  Swedish participation in the EU DataGrid project: VR (SWEGRID) is an associate partner to CERN.  WP2 Data Management (PDC), WP6 Testbeds (NorduGrid), WP8 HEP Applications (NorduGrid), WP10 Biology Applications (KI),  In total EU-IST funds different Grid projects (DataGrid, CrossGrid, DataTag, EGSO, Gridlab,…) – ranging from applications to middleware to infrastructure – for 36 MEuro

15. Paula Eerola Lunarc, 19.4.2002 15 Planned future: Nordic Data Grid Facility  In 2004 it is foreseen that a Nordic Data Grid Facility will be created.  The Nordic Facility will be a so-called Tier-1 Centre with a capacity of about 1700 x (Dual 1 GHz Intel PIII) plus fileservers and tape robots.  Financial scope 150 MSEK (16MEuro).  The Facility will serve all interested fields of science.

16. Paula Eerola Lunarc, 19.4.2002 16 Nordic Data Grid Facility  Working paper by a NOS-N working group (April 4, 2002): road map towards the Nordic Grid Facility Prorotype period 2002- 2004: continued NorduGrid. Scope 0.54 MEuro. Capacity building 2004-2007: Scope 15 MEuro.

17. Paula Eerola Lunarc, 19.4.2002 17 Planned future: Sweden  Continued NorduGrid 2002-2004: build-up of competence in Lund-EPF and elsewhere.  Build-up of resources: multidisciplinary project for Development of GRID testbed in Sweden in preparation.  Includes biomedical science, earth sciences, space/astrophysics, high- energy physics (incl. Lund-EPF), information sciences, computer centers (incl. Lunarc).  Could become part/first phase of the Nordic Data Grid Facility.
