  1. Global Grid User Support (GGUS) Status and Prospects GDB-Meeting 2004-01-13Rainer Kupsch GridKa Karlsruhe

  2. Support in the Grid Environment • Cern User Support (CUS) • Experiment integration? • Solves deployment problems (LCG) • Experiment Specific User Support (ESUS) • Solves experiment specific user problems • Grid Operations Centre (GOC) at RAL • Monitoring, Security, Accounting of Grid • Co-operates with system administrators • Doesn‘t want direct contact with users • Global Grid User Support (GGUS) • Solves Grid specific problems • Co-operates with users • Started with support for GridKa Users (2003-10-02) • Interacts with CUS, ESUS and GOC

  3. Objectives and Status of GGUS • Uses a problem management tool (Remedy in FZK) to support problem tracking (+) • Provides an entry point for GRID related questions and problems (FAQs) (+) • Provides Grid users with news, information on temporary problems, bottlenecks and down times (+) • Provides support for GRID users via web portal with secure access (+ ,-) • Provides status & diagnostic information about GRID resources (+,-) • Provides access to documentation and information (+) • Builds an open knowledge base to optimize GRID-support (-) • Provides support for CUS, ESUS and GOC (-) • Interacts with CUS, ESUS, GOC and possibly local operations (-) • Provides7*24 hours support, therefore we have to find 2 partners in 2 different time zones (-) + : established - : to be established

  4. To Do (1) • Integration of a universal Authentication and Authorization (A&A) system for internal use of GGUS-Portal for registered Grid users • Web access to non public areas via browser certificates with additional Authorization and user information (e.g. email, phone, experiment) • Therefore a (logical) central LDAP directory with a unique structure for A&A and for every VO has to be defined and established

  5. To Do (2) • Integration of Cern User Support (CUS), GGUS could be first line of support • Needed is at least one contact person from CUS who feels responsible for: • Review of GGUS Portal for the needs of CUS • Characterization of the 2 CUS groups and integration in our problem management tool for filtered problem transmission from GGUS to CUS • Delivery of information on deployment dates and news about CERN software to GGUS • Definition and implementation of interfaces and workflows between CUS tools and GGUS tools in co-operation with GOC • Making affected CERN users familiar with new procedures First contact with Andrea Sciaba and Markus Schulz

  6. To Do (3) • Closer co-operation with GOC, system and user related problems are transmitted from GOCto GGUS • Review of GGUS Portal for the needs (e.g. problem categorization and escalation) of GOC • Further definition of responsibilities (e.g. who develops what kind of tools) • Definition of interfaces and workflows between existing GOC tools and GGUS tools • Implementation and tests of the proposed interfaces and workflows

  7. To Do (4) • Co-operation with Experiment Specific User Support (ESUS) Groups, GGUS will be second line of support • Needed is at least one contact person for each experiment who feels responsible for: • Review of GGUS Portal for the needs of ESUS • Definition of responsibilities • Definition of interfaces and workflows between ESUS tools and GGUS tools • Implementation and tests of the proposed interfaces and workflows • Training of ESUS people in new procedures • Making experiment users familiar with new procedures

  8. To Do (5) • Integration of further Tier1 Centres,GGUS first line of support • Needed is at least one contact person for each Tier1 who feels responsible for: • Review of GGUS Portal for the needs of Tier1 • Definition and implementation of interfaces and workflows between Tier1 tools and GGUS tools in co-operation with GOC • Making Tier1 users familiar with new procedures

  9. To Do (6.1) • Finding 2 partners in 2 different time zones • First contact with Computing Centre, Academia Sinica, Taiwan • potential partners:Fermilab in Batavia, Illinois, USA or • SLAC in Stanford, USA

  10. To Do (6.2) • Co-operation with 2 partners • Concept and implementation for replication and distribution, world-wide universal access point to GGUS portal, single email address and phone number • Definition of responsibilities within GGUS portal • Definition and implementation of failover procedures

  11. GGUS Team will be extended (hopefully) by 1 more person at 2004/07/01 Roland Pietschmann, mathematician coordinator and instructor Helmut Dres, geo physicist support Günter Grein, computer scientist support

  12. Access and Links • Support time: • Monday to Friday 8:00 am to 4:00 pm • Email: Support@ggus.org • Phone: 0049/(0)7247/82-8383 • GGUS-Portal: • Address: www.ggus.org • Link from www.gridka.de • User Access to non-public areas: Login: gridka Password: ******
