LHCb Progress & Plans Nick Brook University of Bristol

1. LHCb Progress & Plans Nick Brook University of Bristol • News & User Plans • Technical Progress • Review of deliverables Cosener’s House – 30th Jan’03

2. Xmas MC production • 4.4M event produced over Xmas • All 8 UK institutes participated • UK produced ~1/3 of the events • UK produced ~40% of events produced outside of CERN • All DST data copied back to CERN • Data currently stored at some production sites (Cambridge, RAL & ScotGrid) • DataGrid just another “site” Cosener’s House – 30th Jan’03

3. Xmas Production • 4.4M event produced over Xmas correspond to < 1Tb of DSTs • If required the whole of the DSTs produced can reside on disk at RAL • Data transfer tools have been (and still are) being developed at CERN – production centre manager tool • New book-keeping database available that allows replica dataset also to be stored • Should be able to generate files that need to be replicated to local site from DB • Should be able to generate file i/p “opt” files from DB for each site Cosener’s House – 30th Jan’03

4. Data Challenge & Summer analysis • Data Challenge due to commence Feb (for 3 months)  10-20M events • Unlikely all DSTs will be available on disk at RAL (but might.) Need to use MSS at RAL ?? • LHCb UK investigating “namespce” convention to allow long name (i.e. disk file type name) access to data. Investigation of tools from BaBar – ATLAS involvement as well Cosener’s House – 30th Jan’03

9. POOL activities • Catalog & Grid work package • Provided file catalog browser (PYTHON) • Code submitted to CVS repository Carmine Cioffi Cosener’s House – 30th Jan’03

10. GANGA - activities Karl Harrison & Alexander Soroko • Demonstration later today – see Alexander’s talk • Fortnightly telephone meetings – CERN/UK/LBL • Web site exists – http://ganga.web.cern.ch/ganga/ • Close working relationship with LCG PI project & US Grappa project Cosener’s House – 30th Jan’03

11. Deliverable Review • LHC experiments will be an integral part of the CERN LCG project • LCG currently defined “middleware” to appear on their testbed • LHCb UK hope to re-align deliverables with LCG • Will review the situation ~March • First “public” release of LCG facilities – July’03 Cosener’s House – 30th Jan’03
