MC/OFFLINE meeting News since the last meeting LNF 23-04-2008 News since the last meeting Pending requests: what to do next? Status of tape space aob

News Data reprocessing finished: the whole 2005 dataset is now available in dbv-26 1.2 fb-1 in run range 34280-41902, rate=35pb-1/day (144 pb-1 weren't available before) Some dedicated MC have been produced (2weeks): wp off-peak 2006 (200pb-1) omegapi → ok Bhabha 2002 (240pb-1) bha20bab Bhabha off-peak 2006 (200pb-1) eeg10 → ok On going (2 weeks): Bhabha 2004-2005 eeg100

Requests Other possibilities Nguyen: 2006 data reprocessing (i.e. 240 pb-1) with new  selection (~10 days only reprocessing) algorithm ready: to be discussed (see presentation) Meola: MC production for Kl4 measurement containing Kl4 (signal) and K3p and Kl4 (backgrounds) 2004-2005 with LSF ≥ 3 Other possibilities Produce more MC for 2004-2005, i.e. all_phys4 Reprocess 2001-2002 with DBV-26 (uniform dataset)

Data census: dst Size in pb-1 Year vs DBV Total 1064 Run available in N versions enter N times

Data census: datarec Size in pb-1 Year vs DBV Total 1163 Run available in N versions enter N times

Run in multiple versions datarec 15071 7887 613 86 2 dst 14877 7248 411 datarec: “multiversion” run mainly spread in 2002 dst: 2002 (23546-26000) in two versions 14 and 22 2002 (26000-26900) in three versions 14, 22 and 26 2005 (1000 spread runs) only in version 26

Proposal Immediately 1- Delete 2005 Data old DBV (datarec) 55 TB 2- Delete old unused MC dst (if any...) 1 TB 3- Delete old unused MC mcr 1 TB 4- Delete MC mcr when dst available 64 TB After KGM-Ponza 5- Delete 2005 Data old DBV (dst) 22 TB 6- Remove other multiversion runs

Proposal Next offline programs: 1- 2006 data reprocessing 2- MC production for Kl4 measurement 3- MC all_phys4 (?) 4- 2001-2002 data reprocessing (?)
