8. AHM2004, Nottingham, September 2004 - 8 production grid service Launched Sept’03 with 12 sites, now more than 70 sites and continues to grow Live updates http://goc.grid-support.ac.uk/lcg2

9. AHM2004, Nottingham, September 2004 - 9 Current production mware: LCG-2 Regular updates (latest is LCG-2.2.0 August 2004 ) short term developments driven by operational priorities Computing clusterNetwork resourcesData storage Operating systemLocal schedulerFile system User accessSecurityData transferInformation schema Resource BrokerData managementApp monitoring system User interfaces Applications Hardware System software “Basic” services “Collective” services Application level services HPSS, CASTOR… RedHat Linux NFS, … PBS, Condor, LSF,… VDT (Condor, Globus, GLUE) EU DataGrid Information system

10. AHM2004, Nottingham, September 2004 - 10 Running the Production Service Grid deployment has entered a new phase Basic middleware is working responsible now for a small fraction of the problems Outstanding performance/functionality issues RLS, RB / little modularity & lack of consistent interfaces … some solutions are being developed but many cannot be addressed in current software/architecture - set priorities for new middleware (gLite) Many operational issues mis-configuration, out of date mware, single points of failure, failover, mgmt interfaces … resources unsuitable for applications needs (e.g. insufficient disk space) slow response by sites to problems (holiday periods, security concerns) new middleware will not help for many of these issues - grid partners must think Service The grid still does not appear as a single coherent facility applications must adapt to the current service to gain maximum profit but result has been very effective for LHCb - ~3000 concurrent jobs (August)

11. AHM2004, Nottingham, September 2004 - 11 Intended to replace LCG-2 Starts with existing components from AliEN, EDG, VDT etc. Aims to address LCG-2 shortcoming and advanced needs from applications Prototyping short development cycles for fast user feedback Initial web-services based prototypes being tested with representatives from the application groups Future EGEE Middleware - gLite Globus 2 basedWeb services based gLite-2gLite-1LCG-2LCG-1 Application requirements http://egee-na4.ct.infn.it/requirements/http://egee-na4.ct.infn.it/requirements/

12. AHM2004, Nottingham, September 2004 - 12 Architecture Guiding Principles Lightweight (existing) services Easily and quickly deployable Use existing services where possible as basis for re-engineering Interoperability Allow for multiple implementations Resilience and Fault Tolerance Co-existence with deployed infrastructure Reduce requirements on site components Co-existence (and convergence) with LCG-2 and Grid3 are essential for the EGEE Grid service Service oriented approach Follow WSRF standardization No mature WSRF implementations exist to date so start with plain WS (WS-I) Provide framework to others so higher-level services can be developed quickly Architecture: https://edms.cern.ch/document/476451https://edms.cern.ch/document/476451

13. AHM2004, Nottingham, September 2004 - 13 gLite Approach Exploit experience and components from existing projects AliEn, VDT, EDG, LCG, and others Design team works out architecture and design Feedback and guidance from EGEE PTF & applications; Operations, LCG GAG & ARDA Components are initially deployed on a prototype infrastructure Small scale (CERN & Univ. Wisconsin) Get user feedback on service semantics and interfaces After internal integration and testing, components are delivered to grid operations group and deployed on the pre-production service EDGVDT... LCG...AliEn Draft Design - https://edms.cern.ch/document/487871/https://edms.cern.ch/document/487871/ PTF – Project Technical Forum (http://egee-ptf.web.cern.ch/egee-ptf/default.htm)http://egee-ptf.web.cern.ch/egee-ptf/default.htm GAG – Grid Application Group (http://project-lcg-gag.web.cern.ch/project-lcg-gag/)http://project-lcg-gag.web.cern.ch/project-lcg-gag/) ARDA - A Realisation of Distributed Analysis for LHC (http://lcg.web.cern.ch/LCG/peb/arda/Default.htm)http://lcg.web.cern.ch/LCG/peb/arda/Default.htm

14. AHM2004, Nottingham, September 2004 - 14 Deployment considerations Interoperability and co-existence Exploit different service implementations  E.g. Castor and dCache SRM implementations Flexible service deployment  Multiple services running on the same physical machine (if possible) Platform support Goal is to have portable middleware Building & Integration on RHEL 3 and windows Initial testing (at least 3 sites) using different Linux flavors (including free distributions) Service autonomy User may talk to services directly or through other services (like access service)

15. AHM2004, Nottingham, September 2004 - 15 gLite security Aims at being Modular – add new modules later Agnostic – modules will evolve Standard – start with transport-level security but intend to move to WS-Security when it matures Interoperable - at least for AuthN & AuthZ Applied to Web-services hosted in containers and applications (Apache Axis & Tomcat) as additional modules Draft security architecture: https://edms.cern.ch/document/487004/https://edms.cern.ch/document/487004/

AHM2004, Nottingham, September 2004 - 17 LCG-2 Current base for production services Evolves with certified new or improved services from the preproduction Pre-production Service Early application access for new developments Certification of selected components from gLite Starts with LCG-2 Migrate new mware in 2005 Organising smooth/gradual transition from LCG-2 to gLite for production operations EGEE Middleware Migration LCG-2 (=EGEE-0) prototyping product 2004 2005 LCG-3 (=EGEE-x?) product

18. AHM2004, Nottingham, September 2004 - 18 Intellectual Property The existing EGEE grid middleware (LCG-2) is distributed under an Open Source License developed by EU DataGrid Derived from modified BSD - no restriction on usage (academic or commercial) beyond acknowledgement Same approach for new middleware (gLite) Application software maintains its own licensing scheme Sites must obtain appropriate licenses before installation

19. AHM2004, Nottingham, September 2004 - 19 Who else can benefit from EGEE? EGEE Generic Applications Advisory Panel: 4 applications presented 3 applications (comp. chemistry, earth science, astro-particle) recommended for deployment with allocation of NA4 resources EU GRACE project already tested EU projects: MammoGrid, Diligent, SEE- GRID … Expression of interest: Planck/Gaia (astroparticle), SimDat (drug discovery) http://agenda.cern.ch/age?a042351 Next meeting at EGEE conference (November)

20. AHM2004, Nottingham, September 2004 - 20 Bringing new applications to the grid 1. Outreach events inform people about the grid / EGEE 2. Application experts discuss specific characteristics with the users 3. Migrate application to EGEE infrastructure with the help of EGEE experts 4. Initial deployment for testing purposes 5. Production usage - user community contributes computing resources for heavy production demands - “Canadian dinner party”

21. AHM2004, Nottingham, September 2004 - 21 Private vs Federated Resources For applications that must operate in a closed environment, EGEE middleware can be downloaded and installed on closed infrastructures Approach being used by MammoGrid EGEE sites are administered/owned by different organisations Sites have ultimate control over how their resources are used Limiting the demands of your application will make it acceptable to more sites and hence make more resources available to you

22. AHM2004, Nottingham, September 2004 - 22 User training and induction Training material and courses from introductory to advanced level Train a wide variety of users both internal to the EGEE consortium and external groups from across Europe ~20 courses/presentations already held and many more planned (see roadmap) Experience with GENIUS portal and GILDA testbed Courses inline with the needs of the projects and applications Training: http://www.egee.nesc.ac.uk/http://www.egee.nesc.ac.uk/ Roadmap: http://www.egee.nesc.ac.uk/schedreg/index.htmlhttp://www.egee.nesc.ac.uk/schedreg/index.html
