This page is a record of the configuration for the P120 reprocessing project, event reclassification using Pass 7.3/7.4. This project involves reprocessing with Pass7 classification trees and (ultimately) new IRFs. The name "P120" derives from the word "processing" and the initial file version to be used for the output data products, e.g., r0123456789_v120_merit.root.

Status chronology

• 4/19/2011 - Begin reprocessing block 10, through run 324849509 (2011-04-18 19:58:27 UTC)
• 4/15/2011 - Begin and complete reprocessing block 9, through run 239557417 (2011-04-15 10:51:27 UTC)
• 4/13/2011 - Begin and complete reprocessing block 8, through run 324368491 (2011-04-13 06:21:29 UTC)
• 4/3/2011 - The three missing runs have been produced by Level 1. Runlist recreated and those runs rolled back. There are no missing runs at this point.
• 3/29/2011 - Due to some hidden I/O problems, two changes have been made to this task, neither of which should affect data content. Note that this change will take effect on runs after 321756673, or any runs rolled back after this date.

  Package	Old Version	New Version	Reason for change
  GPLtools	v1r15p1	GPLtools-02-00-00	Checks size of files before and after move between disk and xroot
  skimmer	07-07-00	08-01-00	detects failure to open input file

• 3/17/2011 - Last block complete (one instance of skimmer failure in mergeClumps)
• 3/15/2011 - Expand P120 to present (last run 321756673, 2011-03-14 00:51:11 UTC). Three runs continue to be dummied out. Once those runs have proper RECON files, their streams can be rolled back.

  run	task stream	# subStreams
  306353950	11624	10
  316611240	13431	8
  320850543	14171	7

• 2/4/2011 - Expand P120 to present (last run 318211122, 2011-01-31 23:58:40 UTC). This include three runs for which there are no Recon files which have, for the moment, been supplied with 'dummy' entries in the runFile.:

  306353950	'bad chunk' (known previously) - awaiting GR update
  313483912	missing 700s, being worked on
  316611240	'bad chunk' - awaiting GR update

• 1/12/2011 - Expand P120 coverage to include Crab ToO
  • Crab ToO 9/23/2010 15:50:50 to 9/27/2010 19:49:38, corresponding to MET r0306949696-r0307308940
  • reconfig through end of Sep 2010: 10916 -> 11841 runs, increase of 925 runs
  • No recon file for run 306353950 (being worked on, for the moment, place dummy file in runFile.txt)
  • First run in new block completed, awaiting checkered flag to continue...
• 8/29/2010 - Discovered three merge steps that silently failed (xroot file access). TASK complete.
• 8/28/2010 - processing formally complete (10916 runs), but some discrepancy in # of events
• 8/26/2010 - serious xroot problems. See initial distribution of files across xroot servers. From this report (courtesy Wilko) it is easy to see where problems are likely to arise - when the number of servers involved is small, e.g. two or three.
• 8/19/2010 - production continues at a crawl due to xroot server difficulties
• 8/16/2010 - resume full production, but at a slow trickle (max 350 simultaneous processClump jobs)
• 8/8/2010 - block 2 reprocessing complete. Many xroot server problems. (5 days to process 2084 runs)
• 8/3/2010 - begin block 2 reprocessing (through 255132033 MET), bringing the total runs reprocessed to 2721, about 5-1/2 months of data.
• 7/28/2010 - block 1 re-reprocessing complete
• 7/27/2010 - New GlastRelease (v17r35p10) containing new evtUtils, "to make the FT1EventClass bits compatible with the ScienceTools". Cleanup, including removing all files created last week during the first attempt.
• 7/21/2010 - block 1 reprocessing complete
• 7/20/2010 - agree upon 'pilot block' of runs (239557417 - 243220241), 637 runs. Begin...
• 7/19/2010 - submit first test run. success. await feedback
