1 Tony Doyle - University of Glasgow GridPP EDG - UK Contributions Architecture Testbed-1 Network Monitoring Certificates & Security Storage Element R-GMA LCFG MDS deployment GridSite SlashGrid Spitfire… Applications (start-up phase) BaBar CDF/D0 (SAM) ATLAS/LHCb CMS (ALICE) UKQCD £17m 3-year project funded by PPARC CERN - LCG (start-up phase) funding for staff and hardware... £3.78m £5.67m £3.66m £1.99m £1.88m CERN DataGrid Tier - 1/A Applications Operations

2 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

3 Tony Doyle - University of Glasgow GridPP Sites in Testbed: Status 19 Jul :52 Project Map Software releases at each site

4 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

5 Tony Doyle - University of Glasgow UK Tier-2 ScotGRID ScotGrid Processing nodes at Glasgow 59 IBM X Series 330 dual 1 GHz Pentium III with 2GB memory 2 IBM X Series 340 dual 1 GHz Pentium III with 2GB memory and dual ethernet 3 IBM X Series 340 dual 1 GHz Pentium III with 2GB memory and Mbit/s ethernet 1TB disk LTO/Ultrium Tape Library Cisco ethernet switches ScotGrid Storage at Edinburgh IBM X Series 370 PIII Xeon with 512 MB memory 32 x 512 MB RAM 70 x 73.4 GB IBM FC Hot- Swap HDD CDF equipment at Glasgow 8 x 700 MHz Xeon IBM xSeries GB memory 1 TB disk Griddev testrig at Glasgow 4 x 233 MHz Pentium II 2004 Scale: 300 CPUs 0.1 PBytes BaBar UltraGrid System at Edinburgh 4 UltraSparc 80 machines in a rack 450 MHz CPUs in each 4Mb cache, 1 GB memory Fast Ethernet and Myrinet switching

6 Tony Doyle - University of Glasgow Network Network Internal networking is currently a hybrid of –100Mb(ps) to nodes of cpu farms –1Gb to disk servers –1Gb to tape servers UK: academic network SuperJANET4 –2.5Gb backbone upgrading to 20Gb in 2003 EU: SJ4 has 2.5Gb interconnect to Geant US: New 2.5Gb link to ESnet and Abilene for researchers UK involved in networking development –internal with Cisco on QoS –external with DataTAG
