LHCb(UK) Computing Status Glenn Patrick 05.07.00 Prototype (Tier 1) UK national computing centre Bid to Joint Infrastructure Fund (JIF) for £5.9M. Submitted in Feb 2000, outcome known in ~ Nov. Sited at RAL. Shared between ALICE/ATLAS/CMS/LHCb. All UK LHC institutes signed bid. Integrated Resources 2001 2002 2003 Processors (PC99-450MHz) 830 1670 3100 Disk (TB) 25 50 125 Tape (TB) 67 130 330 05/07/00 LHCb Computing Model Meeting (CERN)

UK Tier 2 Centres? Liverpool MAP/COMPASS (LHCb/ATLAS) Funded by Joint Research Equipment Initiative (JREI) 1998. 300 PCs (400MHz,PII) and 3*1TB disk nodes. Operational since December 1999. Prototype Scottish Computing Centre (LHCb/ATLAS) Bid to Joint Research Equipment Initiative (JREI) May 2000. Outcome known in ~ December. MC prod.facility (128 cpus+1TB RAID) at Glasgow. 5TB RAID disk array + server at Edinburgh.

Other Initiatives Long Term Science Review (PPARC) LHC computing/Grid identified as priority. Government Spending Review - indication in July, details known in October/November? EU Data Grid Proposal UK (PPARC) is one of the lead partners. IBM(UK) is industrial partner. Committees and “teams” evolving. Preliminary answer in July?
