Cosener’s House – 30 th Jan’031 LHCb Progress & Plans Nick Brook University of Bristol News & User Plans Technical Progress Review of deliverables

Cosener’s House – 30 th Jan’032 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 – 30 th Jan’033 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 – 30 th Jan’034 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
