Tony Doyle - University of Glasgow GridPP – Achievements and Issues 1st Year Achievements Complete Project Map –Applications: Middleware: Hardware Fully integrated with EU DataGrid and LCG Projects Rapid middleware deployment /testing Integrated US-EU applications development e.g. BaBar+EDG Roll-out document for all sites in the UK (Core Sites, Friendly Testers, User Only). Testbed up and running at 15 sites in the UK Tier-1 Deployment 200 GridPP Certificates issued First significant use of Grid by an external user (LISA simulations) in May 2002 Web page development (GridSite) Issues for Year 2 Status: 19 Jul :52 GMT – keep monitoring and improve testbed deployment efficiency Importance of EU-wide development of middleware Integrated Testbed for use/testing by all applications Reduce integration layer between middleware and application software Integrated US-EU applications development Tier-1 Grid Production Mode Tier-2 Definitions and Deployment Integrated Tier-1 + Tier-2 Testbed Transfer to UK e-Science CA Integration with other UK projects e.g. AstroGrid

Tony Doyle - University of Glasgow UK Tier-1 RAL New Computing Farm 4 racks holding 156 dual 1.4GHz Pentium III cpus. Each box has 1GB of memory, a 40GB internal disk and 100Mb ethernet. 50TByte disk-based Mass Storage Unit after RAID 5 overhead. PCs are clustered on network switches with up to 8x1000Mb ethernet out of each rack. Tape Robot upgraded last year uses 60GB STK 9940 tapes 45TB currrent capacity could hold 330TB Scale: 1000 CPUs 0.5 PBytes
