3. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board What was GridPP1? A team that built a working prototype grid of significant scale > 2,000 (9,000) CPUs > 1,000 (5,000) TB of available storage > 1,000 (6,000) simultaneous jobs A complex project where 88% of the milestones were completed and all metrics were within specification A Success “The achievement of something desired, planned, or attempted”

4. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board What is GridPP2? Structures agreed and in place (except LCG phase-2) 253 Milestones, 112 Monitoring Metrics at present. Must deliver a “Production Grid”: robust, reliable, resilient, secure, stable service delivered to end-user applications. The Collaboration aims to develop, deploy and operate a very large Production Grid in the UK for use by the worldwide particle physics community.

5. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board Vision 1.SCALE: GridPP will deliver Grid middleware and hardware infrastructure to enable the construction of a UK Production Grid for the LHC of significant scale. 2.INTEGRATION: The GridPP project is designed to integrate with the existing Particle Physics programme within the UK, thus enabling full use of Grid technology and efficient use of shared resources. 3.DISSEMINATION: The project will disseminate the GridPP deliverables in the multi- disciplinary e-Science environment and will seek to build collaborations with emerging non-PPARC Grid activities both nationally and internationally. 4.UK LHC COMPUTING: The main aim is to provide a computing environment for the UK Particle Physics Community capable of meeting the challenges posed by the unprecedented data, processing and analysis requirements of the LHC experiments. 5.OTHER UK PARTICLE PHYSICS COMPUTING: The process of creating and testing the computing environment for the LHC will naturally support the current and next generation of highly data intensive Particle Physics experiments. 6.EGEE: Grid technology is the framework used to develop the required capability: key components will be developed as part of the EGEE project and elsewhere. 7.LCG: The collaboration builds on the strong computing traditions of the UK at CERN. GridPP will make a strong contribution to the LCG deployment and operations programme. 8.INTEROPERABILITY: The project is integrated with national and international developments from other Grid projects and the GGF in order to ensure a common set of principles, protocols and standards that can support a wide range of applications. 9.INFRASTRUCTURE: Provision is made for a Tier-1 facility at RAL and four Regional Tier-2s, encompassing the collaborating Institutes. 10.OTHER FUNDING: The Tier-1 and Tier-2s will provide a focus for dissemination to the academic and commercial sector and will attract additional funds such that the full programme can be realised.

6. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board Must share data between thousands of scientists with multiple interests link major (Tier-0 [Tier-1]) and minor (Tier-1 [Tier-2]) computer centres ensure all data accessible anywhere, anytime grow rapidly, yet remain reliable for more than a decade cope with different management policies of different centres ensure data security be up and running routinely by 2007 What are the Grid challenges?

14. Tony Doyle - University of Glasgow 12 January 2005Collaboration Board Is GridPP a Grid? 1.Coordinates resources that are not subject to centralized control 2.… using standard, open, general-purpose protocols and interfaces 3.… to deliver nontrivial qualities of service 1.YES. This is why development and maintenance of LCG is important. 2.YES. VDT (Globus/Condor-G) + EDG/EGEE(Glite) ~meet this requirement. 3.YES.
