  1. UK QCDgrid status • data grid running across 6 UK sites • ACF Edinburgh, Edinburgh, Liverpool, RAL, Southampton, Swansea • Linux PC + 10 TB RAID, based on Globus 2.4 • Large SAN connected to QCDOC partially integrated – 50 TB • Using QDP/Chroma to convert QCDOC data (incomplete Nersc) to ILDG format Chris Maynard

  2. Software status • QCDgrid1.3 is released • Download from • http://forge.nesc.ac.uk/projects/qcdgrid/ • Metadata handling for data submission • Job submission • Running on top of globus 2.4 • watching developments • Globus 4 • EGEE middleware Glite Chris Maynard

  3. Metadata • QCDml1.1 • UKQCD legacy data • NP Clover • QCDml1.2 • New data from QCDOC is being processed • Metadata catalogue is public • No ILDG service yet (PTO) • Static HTML document on ILDG pages lists Ensembles Chris Maynard

  4. Future developments • ILDG middleware WG • MDC service nearly specified • Funded effort for implementing this service • Design phase • Implement by May/June • MWWG to specify RC service after this during the summer Chris Maynard
