Tony Doyle - University of Glasgow Provide architecture and middleware Use the Grid with simulated data Use the Grid with real data Future LHC Experiments Running US Experiments Build Tier-A/prototype Tier-1 and Tier-2 centres in the UK and join worldwide effort to develop middleware for the experiments GridPP Bridge

8. Tony Doyle - University of Glasgow GridPP Vision From Web to Grid - Building the next IT Revolution Premise The next IT revolution will be the Grid. The Grid is a practical solution to the data-intensive problems that must be overcome if the computing needs of many scientific communities and industry are to be fulfilled over the next decade. Aim The GridPP Collaboration aims to develop and deploy a large-scale science Grid in the UK for use by the worldwide particle physics community. Many Challenges.. Shared distributed infrastructure For all applications

9. Tony Doyle - University of Glasgow GridPP Objectives 1.SCALE: GridPP will deploy open source Grid software (middleware) and hardware infrastructure to enable the testing of a prototype of the 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 early deployment and full testing of Grid technology and efficient use of limited 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 PHYSICS ANALYSES (LHC): 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 requirements of the LHC experiments. 5.UK PHYSICS ANALYSES (OTHER): The process of creating and testing the computing environment for the LHC will naturally provide for the needs of the current generation of highly data intensive Particle Physics experiments: these will provide a live test environment for GridPP research and development. 6.DATAGRID: Open source Grid technology is the framework used to develop this capability. Key components will be developed as part of the EU DataGrid project and elsewhere. 7.LHC COMPUTING GRID: The collaboration builds on the strong computing traditions of the UK at CERN. The CERN working groups will make a major contribution to the LCG research and development programme. 8.INTEROPERABILITY: The proposal is also integrated with developments from elsewhere in order to ensure the development of a common set of principles, protocols and standards that can support a wide range of applications. 9.INFRASTRUCTURE: Provision is made for facilities at CERN (Tier-0), RAL (Tier-1) and use of up to four Regional Centres (Tier-2). 10.OTHER FUNDING: These centres will provide a focus for dissemination to the academic and commercial sector and are expected to attract funds from elsewhere such that the full programme can be realised.
