1. SouthGrid www.southgrid.ac.uk SouthGrid SouthGrid is a distributed Tier 2 centre, one of four setup in the UK as part of the GridPP project. SouthGrid members include institutes in the south of England except the LondonTier2. SouthGrid also includes institutes which are not at this time participating directly in LCG or EGEE, such as Warwick. The computational and storage resources will be used by high energy physics experiments, particularly those at the CERN Large Hadron Collider. Many of the institutes will be part of the EGEE European project which extends the grid to non HEP users such as Biomedical and Earth Sciences. SouthGrid Management Board Chair: Jeff Tseng Technical Co-ordinator Pete Gronbech University of Birmingham The University of Birmingham currently has 90 processors running LCG grid software and is bringing online a further 160 PIII processors in Babar clusters from two other UK Universities which have been consolidated at Birmingham for more efficient operation and management. It also hosts a Pre-Production grid service and is heavily involved in middleware deployment and testing. The University is currently tendering for a campus- wide 1000 processor farm and associated storage using SRIF3 funds for installation towards the end of 2006. University of Cambridge cont. The group is also involved with CamGrid-LCG integration work, using Condor’s unique flocking mechanism, which if successful will be a most useful project. University of Oxford The University of Oxford currently provides an 80 cpu dedicated cluster running the LCG grid software, and a 30 cpu cluster for the CDF SAM Grid users. A 5 node test cluster is used for pre release testing as part of the UK testzone. Oxford collaborates closely with RAL and enjoys good network connectivity, both being part of the Thames Valley Network. RAL Particle Physics Department The RALPP Tier 2 is a separate entity from the main GridPP Tier 1 at RAL being located in and managed by the Particle Physics Department. It was one of the first UK sites to join LCG Having previously been part of the European DataGrid. It currently provides 100 KSI2k of CPU capacity and 6 TB of storage and has recently purchased an additional 200 KSI2k of CPU and 64TB of disk which will be brought online in the next months. The resources are used by a wide range of Virtual Organisations, including the 4 LHC experiments, smaller experiments like BaBar, D0, H1 and Zeus and even Biomedical Researchers. Support of 13 VO’s keeps the RALPPD cluster fully utilised.

Links to industrial partners Hewlett Packard led to some work with Itanium servers and part funding of a post at Bristol. University of Cambridge The University of Cambridge has been involved with LCG since the days of EDG, being one of the very first few UK members of the community; involved with various experiments including Atlas, LHCb, NA48. and the only UK site using Condor as the primary batch system. This facility consists of a 44 CPU cluster and 3.2TB storage mainly dedicated to LCG and also partly shared across the CamGrid – a university-wide Condor grid, consisting of 8 different pools of around 146 CPUs.
