Additional capacity (GRID) Several centers (Nikhef, Cambridge) are making CPUs exclusively available through DataGrid Status DataGrid?
Organization Most centers are operational now Sw installed Jobs submitted through web interface Output and logs sent back to cern Bookkeeping db updated Install latest versions of Sicbmc and Brunel for test productions, tar files will be provided (next week) Run prototype production (26/6 – 3/7)
Job organization (prototype production) Prototype production mainly done at CERN but will also be used to consolidate outside centers Channel (or generic b/c) job will consist of: Generation of 1 channel/generic b/c set of 1000 events Reconstruction of 1 channel set Channel DST sent back to CERN
Job organization (prototype production) Channel (or background) job will consist of: Generation of 3 mbias sets of 500 events for spillover Generation of 1 channel set of 1000 events All RAWH sent back to CERN Channel DST sent back to CERN
Job organization (production) Channel (or background or b/c inclusive) job will consist of: Generation of 3 mbias sets of 500 events for spillover Generation of 1 background/b/c incl set of 1000 events Channel/background/b/c incl. DST sent back to CERN Mbias DST (500 events) sent back to CERN
Data Quality Check Existing program works with Zebra Needs to be converted to OODST, merged with current histograms in Brunel Centers will be responsible for checking: Size of output datasets Correct filetransfer to CERN Correct updating of bookkeeping db
Improvements to production tools Suggestion for removing site dependencies from Java code to local scripts from Andrei Prototype installed in Lyon, will be tested in production Also installed at CERN, to be tested with new production/configuration/bookkeeping db and tools
