QCD group workflow QCD Low p. T (Min-bias and underlying event studies etc) QCD High p. T (Jets cross-sections, dijet mass resonances etc) QCD Photon (Inclusive photon, diphoton, jet + photon cross -section etc) Tier-2 Secondary data set RECO/AOD Tier-2 Secondary data-set AOD Skims are produced from Tier-2 Secondary data-set using CRAB and will be published to local DBS instances. Produce UE root tuples Produce pruned AOD Produce PAT tuples • More detailed work flow is given in the back up slides. 5
October Exercise Data work-flow testing 6
Low p. T sub-group 7
High p. T sub-group • Test the full data workflow chain from the T 0 to the T 2 s. • We have set specific goals for the October exercise. A few details still need to be taken care of. 8
Photon sub-group Production Gamma Jet Sample Di-jet Sample Z->ee Sample Transfer request to Tier-2 (Caltech CCIN 3 P 2) Completed Test Production of Skims from Teir 2 Secondary data set Currently on going Final Production of Skims (Skim output will be published to Caltech DBS) Next Step • Transfer request Tier-2’s has been successful • Test skim production and publishing to local DBS (with the help of Teir-2 contacts) has been a good experience 9
Summary • Different sub-groups have different data work-flows defined depending on the analysis requirements • About the AOD Usage – Which fraction of your group analyses are currently starting from the AOD ? • 80% – Which fraction of your groups analyses CANNOT start TODAY from the AOD? • 20 % (Ex. Charged track multiplicity distributions using pixels) • We are actively preparing and participating in the October exercise – A special emphasis on testing the data work-flow is being made (and being met with good success). 10
