Additional capacity (GRID)

• Several centers (Nikhef, Cambridge) are making
  CPUs exclusively available through DataGrid
• Status DataGrid?

6
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)

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

8
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

9
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

10
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

11
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
