6. Brussels - 20 June 2006 GridCoord Review 6 Workshop conclusions (1) Grid is still in infancy A commonly agreed basis is needed for a head start The community has to involve even more

7. Brussels - 20 June 2006 GridCoord Review 7 Workshop conclusions (2) Grid in general is still unexplored A programming nightmare Fundamental research remains to be made Business grids haven't focussed on user requirements Gap between science grids and business grids The Grid world is open source ≠ enterprise Missing programming models Missing properties

8. Brussels - 20 June 2006 GridCoord Review 8 Workshop conclusions(3) Many missing features: Specifications, accounting, interoperability, standards, sustainability, composability, schedulers, stability, dedicated tools, business models... Required: vendor-independent system, from which to build upon There will be a true benefit from a common set (services, interoperable layers, components) Focus on the infrastructure, which will bear all the traffic.

9. Brussels - 20 June 2006 GridCoord Review 9 Workshop conclusions (4) The user community has a role to play enable the uptake of the technologies proposed. push the different communities to worry about real user management VO policies international exchange. This major involvement will accelerate the need for standards, and will pave the way to tomorrow’s Grid.

10. Brussels - 20 June 2006 GridCoord Review 10 The main Grid inhibitors QoS, SLA management, end-to-end security, resources acquisition procedures, fault tolerance.. Dedicated tools and environments, grid programming models (components-based models, service based model, workflows). Standards, interoperability, coordination between middleware. Accounting and billing solutions, intellectual property coverage, legal issues, licensing, common business models.

11. Brussels - 20 June 2006 GridCoord Review 11 A wish list for Grid middleware Interoperability between scheduling offerings and provisioning, interoperability between different implementations, network aware scheduling, scalability, standards based SLA negotiation, components and standard interfaces. Simplified Grid programming and deployment environment, integration frameworks for grid/web application development. Business models.

14. Brussels - 20 June 2006 GridCoord Review 14 ProActive Grid Plugtests October 2004 20 sites in the world: 800 processors Total power: 100 Giga Flops October 2005 40 sites in the world 2700 processors Total power: 450 Giga Flops Highly heterogeneous : Machines:IBM, SGI, Sun, Bull, Mac OS: Linux, Windows, Solaris, MacOS, SGI Irix JVMs: Sun, SGI, BEA Protocols:ssh, rsh, sshGSI, Globus Gram Job Schedulers: PBS, LSF, Grid Engine, Oar, Prun, Globus

15. Brussels - 20 June 2006 GridCoord Review 15 The PlugTests Difficulties in setting up the Grid itself Participating sites administrative/legal difficulties Not enough flexibility (firewall permissions) Grid construction and maintenance subGrids presenting defects to their own API Missing protocols Operating System incompatibility (gLite) Missing middleware features Good experience, will help the Grid community in its improvement and development User feedback generally good Computational results  ease of use

16. Brussels - 20 June 2006 GridCoord Review 16 Conclusion PlugTests, workshops (GridCoord, CoreGrid, Unicore), meetings, tutorials A success (+240 people) This kind of hands-on event, where one team deploys some kind of a Grid, specifying some restrictions for using it, can only be good for the Grid community. allows knowledge sharing Fosters communication PlugTests a technical achievement and attractor for the community.

18. Brussels - 20 June 2006 GridCoord Review 18 Some key sentences of the panel Enterprises just wait for more maturity of the Grid middleware. Open source reference implementations are very important. They are required to help validating the standards, to help the early adoption of the standards, and the business uptake of grid technologies. The actual service level is typically only best effort. A competitive environment has to be built, but this will only be possible through standards. We need to find an agreement on one open service architecture. We need to standardize and automate provisioning of servers and data, with different ROI (return on investment), guaranteed QoS (quality of service), accounting, and enforced security policies. Grid world is open source, and not enterprise; bringing these two worlds together is challenging. A lot of the Grid issues are solvable in the coming 4-5 research years.
