  2. Contents • Very Brief overview of EGEE & LCG • Objectives and status • How they relate to each other • The ARDA project • Middleware planning • Organisation • Key middleware deliverables and milestones • Strategy being adopted • Current Status • Summary e-Science Grids and Web Services meeting, 23th April 2004 - 2

  3. EGEE manifesto:Enabling Grids for E-science in Europe • Goal • Create a wide European Grid production quality infrastructure on top of present and future EU RN infrastructure • Build On: • EU and EU member states major investments in Grid Technology • International connections (US and AP) • Several pioneering prototype results • Large Grid development teams in EU require major EU funding effort • Approach • Leverage current and planned national and regional Grid programmes • Work closely with relevant industrial Grid developers, NRENs and US-AP projects Applications Grid infrastructure Geant network e-Science Grids and Web Services meeting, 23th April 2004 - 3

  4. EGEE Partners • Leverage national resources in a more effective way for broader European benefit • 70 leading institutions in 28 countries, federated in regional Grids e-Science Grids and Web Services meeting, 23th April 2004 - 4

  5. EGEE Applications • EGEE Scope : ALL-Inclusive for academic applications (open to industrial and socio-economic world as well) • The major success criterion of EGEE: how many satisfied users from how many different domains ? • 5000 users (3000 after year 2) from at least 5 disciplines • Two pilot applications selected to guide the implementation and certify the performance and functionality of the evolving infrastructure: Physics & Bioinformatics e-Science Grids and Web Services meeting, 23th April 2004 - 5

  6. 24% Joint Research 28% Networking • JRA1: Middleware Engineering and Integration • JRA2: Quality Assurance • JRA3: Security • JRA4: Network Services Development • NA1:Management • NA2:Dissemination and Outreach • NA3: User Training and Education • NA4:Application Identification and Support • NA5:Policy and International Cooperation Emphasis in EGEE is on operating a production grid and supporting the end-users 48% Services • SA1: Grid Operations, Support and Management • SA2: Network Resource Provision EGEE Project Structure 32 Million Euros EU funding over 2 years starting 1st April 2004 e-Science Grids and Web Services meeting, 23th April 2004 - 6

  7. EGEE and LCG EGEE builds on the work of LCG to establish a grid operations service • LCG: a worldwide collaboration of • The LHC experiments • The Regional Computing Centres • Physics institutes • Mission: • Prepare and deploy the computing environment that will be used by the experiments to analyse the LHC data • Strategy: • Integrate thousands of computers at dozens of participating institutes worldwide into a global computing resource • Rely on software being developed in advanced grid technology projects, both in Europe and in the USA • Status: • LCG service up and running with LCG-2 mware – successfully being used for LHC data challenges e-Science Grids and Web Services meeting, 23th April 2004 - 7

  8. LCG The LCG Service • Service opened on 15 September 2003 – with 12 sites • Middleware package components from • European DataGrid (EDG) • US Virtual Data Toolkit (Globus, Condor, PPDG, iVDGL, GriPhyN) • About 30 sites by the end of the year Upgraded version of the grid software (LCG-2) in February 2004 • VO for D0 managed by NIKHEF • Hewlett Packard to provide “Tier 2-like” services for LCG, initially in Puerto Rico e-Science Grids and Web Services meeting, 23th April 2004 - 8

  9. ALICE Distr. analysis ATLAS Distr. analysis CMS Distr. analysis LHCb Distr. analysis ARDA Project Collaboration Coordination Integration Specifications Priorities Planning EGEE Middleware Activity Distributed Physics AnalysisThe ARDA Project ARDA – distributed physics analysis batch to interactive end-user emphasis • 4 pilots by the LHC experiments (core of the HEP activity in EGEE NA4) • Rapid prototyping  pilot service • Providing focus for the first products of the EGEE middleware • Kept realistic by what the EGEE middleware can deliver e-Science Grids and Web Services meeting, 23th April 2004 - 9

  10. VDT EDG . . . LCG-1 LCG-2 EGEE-1 EGEE-2 AliEn LCG . . . Globus 2 based Web services based EGEE EGEE Implementation • From day 1 (1st April 2004) Production grid service based on the LCG infrastructure running LCG-2 grid middleware (SA) LCG-2 will be maintained until the new generation has proven itself (fallback solution) • In parallel develop a “next generation” grid facility (JRA) Produce a new set of grid services according to evolving standards (Web Services) Run a development service providing early access for evaluation purposes Will replace LCG-2 on production facility in 2005 e-Science Grids and Web Services meeting, 23th April 2004 - 10

  11. JRA1: Middleware Engineering and Integration • Objectives Provide robust, supportable middleware components Integrate grid services to provide a consistent functional basis for the EGEE grid infrastructure Verify the middleware forms a dependable and scalable infrastructure that meets the needs of a large, diverse eScience user community • 5 partners, approx 16% of total project budget • 4 main development clusters: • UK • CERN • IT/CZ • Nordic (security, JRA3) e-Science Grids and Web Services meeting, 23th April 2004 - 11

  12. Milestones and Deliverables for 2004 M08 – Amsterdam conference: Tech preview of release candidate 1 available e-Science Grids and Web Services meeting, 23th April 2004 - 12

  13. Towards a Prototype • Design team formed in December 2003 • Started service design based on component breakdown defined by the LCG ARDA RTAG • Leverage experiences and existing components from AliEn, VDT, and EDG. • A working document - Overall design & API’s • Basis for architecture (DJRA1.1 – June ‘04) and design (DJRA1.2 – Aug’04) document • Aim to have first prototype ready by end of April • Focus on key services; exploit existing components • Initially an ad-hoc installation at CERN and Wisconsin • Open only to a small user community • Expect frequent changes (also API changes) based on user feedback and integration of further services • Enter a rapid feedback cycle • Continue with the design of remaining services • Enrich/harden existing services based on early user/operations feedback e-Science Grids and Web Services meeting, 23th April 2004 - 13

  14. Prototype Evolution • Evolution of the prototype • Envisaged status at end of 2004: • Key services need to fulfill all requirements (application, operation, quality, security, …) and form a deployable release • Remaining services available as prototype • Will develop a roadmap • Incremental changes to prototype (where possible) • Early user feedback through ARDA and early deployment on SA1 pre-production service • Detailed release plan being developed e-Science Grids and Web Services meeting, 23th April 2004 - 14

  15. Guiding Principles • Lightweight existing services • Easily and quickly deployable • Interoperability • Allow for multiple implementations • Resilience and Fault Tolerance • Co-existence with deployed infrastructure • Run as an application • Service oriented approach • Follow and contribute production expertise to standardization efforts • No mature WSRF implementations exist to date, hence: start with plain WS – WSRF compliance is not an immediate goal • Review situation end 2004 e-Science Grids and Web Services meeting, 23th April 2004 - 15

  16. Summary • LCG is currently providing a production grid service using the LCG-2 software • EGEE has started 1st April • The first project conference was held in Cork this week and showed that all activities are up and running • Middleware • EGEE will develop a new set of web services based grid middleware • An early prototype will be tested in May • Due to timing issues, the first release will probably only be based on basic web services • EGEE will be involved in the grid standardisation process and is keen to adopt such standards as they become stable e-Science Grids and Web Services meeting, 23th April 2004 - 16
