GridPPe-Science PresentationSlide 5 GridPP Component Model Foundation Value- added Production Middlewar e Exploitation Component 1: Foundation The key infrastructure at CERN and within the UK Component 2: Production Built on Foundation to provide an environment for experiments to use Component 3: Middleware Connecting the Foundation and the Production environments to create a functional Grid Component 4: Exploitation The applications necessary to deliver Grid based Particle Physics Component 5: Value-Added Full exploitation of Grid potential for Particle Physics £21.0M £25.9M

GridPPe-Science PresentationSlide 6 Major Deliverables Prototype I - March 2002 Performance and scalability testing of components Testing of the job scheduling and data replication software from the first DataGrid release. Prototype II - March 2003 Prototyping of the integrated local computing fabric, with emphasis on scaling, reliability and resilience to errors. Performance testing of LHC applications. Distributed HEP and other science application models using the second DataGrid release. Prototype III - March 2004 Full scale testing of the LHC computing model with fabric management and Grid management software for Tier-0 and Tier-1 centres, with some Tier-2 components.

GridPPe-Science PresentationSlide 7 First Year Deliverables Each Workgroup has detailed deliverables. These will be refined each year and build on the successes of the previous year. The Global Objectives for the first year are: Deliver EU DataGrid Middleware (First prototype [M9]) Running experiments to integrate their data management systems into existing facilities (e.g. mass storage) Assessment of technological and sociological Grid analysis needs Experiments refine data models for analyses Develop tools to allow bulk data transfer Assess and implement metadata definitions Develop relationships across multi-Tier structures and countries Integrate Monte Carlo production tools Provide experimental software installation kits LHC experiments start Data Challenges Feedback assessment of middleware tools

GridPPe-Science PresentationSlide 8 GridPP Organisation Software development organised around a number of Workgroups Hardware development organised around a number Regional Centres Likely Tier-2 Regional Centres Focus for Dissemination and Collaboration with other disciplines and Industry Clear mapping onto Core Regional e-Science Centres

GridPPe-Science PresentationSlide 9 GridPP Workgroups A - Workload Management Provision of software that schedule application processing requests amongst resources B - Information Services and Data Management Provision of software tools to provide flexible transparent and reliable access to the data C - Monitoring Services All aspects of monitoring Grid services D - Fabric Management and Mass Storage Integration of heterogeneous resources into common Grid framework E - Security Security mechanisms from Certification Authorities to low level components F - Networking Network fabric provision through to integration of network services into middleware G - Prototype Grid Implementation of a UK Grid prototype tying together new and existing facilities H - Software Support Provide services to enable the development, testing and deployment of middleware and applications at institutes I - Experimental Objectives Responsible for ensuring development of GridPP is driven by needs of UK PP experiments J - Dissemination Ensure good dissemination of developments arising from GridPP into other communities and vice versa Technical work broken down into several workgroups - broad overlap with EU DataGrid

GridPPe-Science PresentationSlide 10 GridPP and CERN UK involvement through GridPP will boost CERN investment in key areas: –Fabric management software –Grid security –Grid data management –Networking –Adaptation of physics applications –Computer Centre fabric (Tier-0) For UK to exploit LHC to the full: Requires substantial investment at CERN to support LHC computing.
