Tony Doyle - University of Glasgow Major Deliverables  Prototype IMar 2002  Performance and scalability testing of components of the computing fabric (clusters, disk storage, mass storage system, system installation, system monitoring) using straightforward physics applications. Testing of the job scheduling and data replication software from the first DataGrid release (M9).  Prototype IIMar 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 (M21).  Prototype IIIMar 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. This will use the software from the final DataGrid release (M33). M9 important: working demonstrators (public spending review) need to ensure key areas are visible

Tony Doyle - University of Glasgow First Year Finances  Funding of PPARC's EU DataGrid staff commitment  Staff to implement initial Grid Testbed in UK  Hardware to satisfy BaBar requirements and EU DataGrid testbed commitment  Staff for CERN LHC computing  Contribution to CERN Tier-0  15 EU DataGrid 3 year posts (already committed) £0.4M  15 GridPP 3 year posts £0.4M  Hardware for BaBar Tier-A/LHC Tier-1 £0.9M  15 CERN 3 year posts £0.5M  Hardware for CERN Tier-0 £0.3M Total £2.5M (Staff costs assume only 6 months of salary in first year) Sets a short-term agenda… complete allocation by December

Tony Doyle - University of Glasgow 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

Tony Doyle - University of Glasgow “two legs good three legs better?” UK ++ Build on Existing Structures. Identify Common Requirements. Establish Group Identity. Reach Out.

Tony Doyle - University of Glasgow Recruitment Timetable  8th October - EB input deadline (just after GGF3).  19th October - TAG assessment document  26th October - PMB definition of tasks inc. allocation of posts to Working Groups  - first review of CERN posts  2nd November - Tender document  5-6th November - Collaboration Meeting  30th November- Deadline for submission  7th December - PRSC mtg.  14th December- summary document submitted to PPARC  outcomes communicated to groups  - second review of CERN posts
