  2. Final Panel: Future of Grids Addressing Scenarios Ischia, Italy - 9-21 July 2006

  3. Introduction to Panel on Grids • Vision of Grid Future • A Place for Today’s Systems in that Future? • Response to Scenario 1 • Response to Scenario 2 • Response to Scenario 3 Ischia, Italy - 9-21 July 2006

  4. The Summer School taught us what? • Collaboration is a challenge • Socio/economic issues • Technology relatively minor • Distributed systems are hard to build & run • Compromises & trade-offs find “sweet” spots • No one can satisfy all of the users all of the time • When you meet a technology • Find out what it is good for • Recognise what it can’t do • Vincent Breton’s Philosophy • Make the most of the current technology Ischia, Italy - 9-21 July 2006

  5. What grids will be in use in 5 to 10 years from now? Ischia, Italy - 9-21 July 2006

  6. Malcolm’s Answer • There will be a pervasive & 24*7 interconnected e-Infrastructure • It will use several underlying technologies • It will seamlessly link: • Major providers and curators of data / information • Who will provide some computation • Personal & group computing resources • Institutional resources • National & International HPC & HTC resources • All major facilities, e.g. Iter, LHC, Diamond, EBI, … • That will be the easy bit • It should mean that • Grids will be hidden & evolving • They will be taken for granted – as IP protocols & http are today Ischia, Italy - 9-21 July 2006

  7. Malcolm’s Answer 2 • People don’t pay for e-Infrastructure • They pay to run applications • Applications are made by developers • It is essential to attract them • And make them productive • Good APIs: abstractions & code mobility • Good tools: diagnostics, deployment, … • Easy to use & powerful components, links & services – the grid equivalent of libraries • Well-resourced user support: consulting, training, outreach, documentation, exemplars, community • This is the hard part! • If we don’t do it there wont be grids in the e-Infrastructure Ischia, Italy - 9-21 July 2006

  8. Other People's Answers What grids be in use in 5 to 10 years from now? Ischia, Italy - 9-21 July 2006

  9. Alain Roy’s Answer Ischia, Italy - 9-21 July 2006

  10. Roberto Barbera’s AnswerLet’s first start with a citation … Telephone, Light bulb, Telegraph, Radio, TV, Computer, Network, PC, Web, … (in the same order as they were invented) Ischia, Italy - 9-21 July 2006

  11. Now the Roberto Barbera’s Answer • The success of the grid in the next 5-10 years will not be decided by the fact that “killer” applications can run on it but, on the contrary,…. • By the fact that e-Infrastructures become pervasive, “transparent”, and we can use them as we today use TV’s and/or cellular phones; • By the general consensus, reached at all levels (social, academic, political, industrial, etc.), that a key enabler of Progress is e-Science. From hardware to middleware to software….to brainware. • I’m convinced that what we are doing here, and with your help, we will surely get there! Ischia, Italy - 9-21 July 2006

  12. Lisa Childer’s Answer Ischia, Italy - 9-21 July 2006

  13. Steven Newhouse’s answer • Pervasive, Invisible & Sustained fabric • Arrive as Web n.0 rather than Grid m.0 • It WILL be standards based • Local isolated standards just cause grief e.g. European mobile phones in Japan • Grid Programming Easier As Programming Easier • ‘Standard’ libraries composed into your application as run-time • Still CS research needed on dynamic composibility Ischia, Italy - 9-21 July 2006

  14. Oscar Corcho’s Answer • Grids that use semantic infrastructure with little user’s intervention (neither end users nor developers) • Service-Oriented Knowledge Utilities • Integrated in Grids as other “traditional” utilities • Addressing the following (non-exhaustive) issues • Trust and security in Virtual Organisations • What’s the best way to join a VO? Best may mean “cheaper”, “faster”, “less bureaucratic” • Higher level of abstraction in resource management • Easier resource discovery and composition • Appropriate management of distributed and incomplete information (and knowledge) • Including privacy and sensitivity issues • Human and societal issues • Costs and culture of knowledge capture, annotation, tagging, curation • Personalisation Ischia, Italy - 9-21 July 2006

  15. Devil’s advocate • Rationale, Foundation • CERN LHC; data storage; cost; • Other scenarios similar? • Which Applications? • Data and/or compute • Compute • Multicore – effort, challenges • FPGAs • HPC, Petascale 2011 • Clusters: Microsoft Ischia, Italy - 9-21 July 2006

  16. Issues • Software • Too difficult, complex • Many approaches, defects? • Is there time for standards? • Sequential applications • People • Career, interesting areas • Social, legal • Industry take up • EU criteria • What is success? • Grid grand challenge Ischia, Italy - 9-21 July 2006

  17. 5 – 10 years • Pure speculation after 3 years • Technology changes • In 5 years funding agencies etc. disillusioned • Little of benefit, banks • Community set back for a generation • Artificial Intelligence • Multidisciplinary wars • Blame game Ischia, Italy - 9-21 July 2006

  20. Question 2: What is your technology good for? What doesn't it do? What will its role be in 5 to 10 years? Ischia, Italy - 9-21 July 2006

  21. The Condor Answer Ischia, Italy - 9-21 July 2006

  22. The OMII-UK Answer: Overview OMII-UK aims to provide software and support to enable a sustained future for the UK e-Science community • Documented web services and tools to access & share resources: • Data access & integration (OGSA-DAI) • JSDL based Job Submission (GridSAM) • UDDI based Registry (Grimoires) • WS-Eventing & Reliable Messaging (FINS & FIRMS) • Client-side environment & APIs – Jython (Geodise) • More components being commissioned & coming soon… Ischia, Italy - 9-21 July 2006

  23. The OMII-UK Answer: Capabilities • It is built from: • High-quality lightweight software components • These have been integrated, tested & documented. • It is easy to install and is supported. • It has not been designed for large-scale production grids • Some components may scale • But not currently our testing ‘sweet spot’ Ischia, Italy - 9-21 July 2006

  24. The OMII-UK Answer: The Future • Our goals are for a long-term future embedded in the e-Science community: • Build on widely supported industrial standards • Currently web services • Meet the needs of a broad community • End-users, developers, technologists, service providers • Commission and use what comes out of the community • Shared repository for code, projects, etc. • Work internationally to create that future • Schools, standards bodies, promotion, meetings, meetings, … • Act as the conduit between research and industry • Sustained future needs industrial providers after trailblazers • Join us – director@omii.ac.uk Ischia, Italy - 9-21 July 2006

  25. 20 sites in 3 continents The EGEE, gLite & GILDA answer gLite is far from being perfect and can/will surely be improved. However, the real strength of EGEE is its “global” approach to determine widely acceptable policies for setting up and operating large e-Infrastructures and to create the huge added value of the human networks running and using them. GILDA Ischia, Italy - 9-21 July 2006

  26. The Globus Answer Ischia, Italy - 9-21 July 2006

  27. The Semantic Grid Answer Ischia, Italy - 9-21 July 2006

  28. Scenario 1 Ischia, Italy - 9-21 July 2006

  29. Sketch of Scenario 1 • Suggested by Mark Thomas • Very Compute Intensive application with a Parametric Study Algorithm built in • Users run on their own machines • With long running times hogging the machines • Want to evolve the application to • A panel in existing GUI to select a grid option • Start grid use optionally after starting the application • Use existing corporate clusters behind scenes • Providing users with progress information • As grid resources are acquired • As parametric search progresses Ischia, Italy - 9-21 July 2006

  30. Sketch of Scenario 1 • Users must be able to • Close & re-open the application • With the search continuing or suspended • Collect and analyse final results • The users should never have to • Use a portal • Use a command line • 100KB input from client to start run • 10MB result set • Which M/W (maybe Grid) would you use? • How would it be used? • How would it be introduced? Ischia, Italy - 9-21 July 2006

  31. Scenario 2 Ischia, Italy - 9-21 July 2006

  32. Sketch of Scenario 2 • Suggested by Bill Pinnington • Perhaps abstract or a real challenge • Organisation A has 200 employees & 200 PCs • Uses a single SQL Server as a Data Warehouse • Jobs run every night • Repopulate data in database tables • Then build multi-dimensional models for next day • For decision support during the next day • Experiencing over-runs to mid morning • Scale of data and complexity increasing • Would a grid enable A to use the PCs to • Cope with current demand and its growth • If so, how should it be introduced? Ischia, Italy - 9-21 July 2006

  33. Scenario 3 Ischia, Italy - 9-21 July 2006

  34. Sketch of Scenario 3 • Marco Serra’s Suggestion • Italian Space Agency • Earth Observation • Seeking to • Improve Application Throughput & Response • Increase scalability • Link multiple data resources • Existing systems are heterogeneous Ischia, Italy - 9-21 July 2006

  35. Sketch of Scenario 3 • Existing applications are platform specific • Interoperation within agency & externally • Needed but doesn’t exist • Installing new H/W & S/W and then porting • Is not feasible • Will grids help • Reducing Application porting costs • Enabling data access and inter-operation? • If so, how?
