3. 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

4. Ischia, Italy - 9-21 July 20064 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

5. Ischia, Italy - 9-21 July 20065

6. 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

7. Ischia, Italy - 9-21 July 20067 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

9. 9 Alain Roy’s Answer

10. Ischia, Italy - 9-21 July 200610 Roberto Barbera’s Answer Let’s first start with a citation … Telephone, Light bulb, Telegraph, Radio, TV, Computer, Network, PC, Web, … (in the same order as they were invented)

11. Ischia, Italy - 9-21 July 200611 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!

12. Ischia, Italy - 9-21 July 200612 Lisa Childer’s Answer

13. Ischia, Italy - 9-21 July 200613 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

14. Ischia, Italy - 9-21 July 200614 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

15. 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

16. 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

17. 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

21. Ischia, Italy - 9-21 July 200621 The Condor Answer

22. Ischia, Italy - 9-21 July 200622 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…

23. Ischia, Italy - 9-21 July 200623 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’

24. Ischia, Italy - 9-21 July 200624 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

25. Ischia, Italy - 9-21 July 200625 The EGEE, gLite & GILDA answer 20 sites in 3 continents GILDA 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.

26. Ischia, Italy - 9-21 July 200626 The Globus Answer

27. Ischia, Italy - 9-21 July 200627 The Semantic Grid Answer

28. Ischia, Italy - 9-21 July 200628

29. Ischia, Italy - 9-21 July 200629 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

30. Ischia, Italy - 9-21 July 200630 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?

31. Ischia, Italy - 9-21 July 200631

32. Ischia, Italy - 9-21 July 200632 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?

33. Ischia, Italy - 9-21 July 200633

34. Ischia, Italy - 9-21 July 200634 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

35. Ischia, Italy - 9-21 July 200635 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?
