This page is a record of the configuration and execution of the P202 reprocessing project, full reprocessing from DIGIs using Pass7 analysis code. This project involves reprocessing with Pass7 classification trees and up-to-date alignment/calibration data. This task will read DIGI files and emit RECON, MERIT, GCR and CAL ROOT files, and the standard array of FITS files. It will be a CPU-intensive and storage-intensive enterprise requiring months of elapsed time and of order 0.7 Pbyte of storage. At the time of this task beginning, there will be about 20,000 science runs in Fermi (3.5 years accumulation).

...

• 3/2/2012 - Define block 1 as the 776 runs in P202-ROOT block 1. Configure trickleStream and begin (14:08)
• 3/31/2012 - Define block 2 as 5600 runs. Reconfig trickleStream and begin (18:05)
• 4/01/2012 - Block 2 complete (most of the 4824 jobs completed in about six hours w/1000 job limit).
• 5/31/2012
  • Discover stream 5599 (run 271999199) requires rollback - new MERIT file version (v203->v205).
  • Regenerate runlist with 20,229 input MERIT files.
  • Minor config change: twoClumpMin=False (formerly True, but caused unnecessary extra processClump dummy jobs)
• 6/5/2012 - Final cleanup
  • Five runs are responsible for discrepant event tallies:

    Run	Stream	Reason	Action
    239557414	0	bad TCut	rollback ROOT + FITS
    241599746	352	bad processing order	rollback FITS
    245403855	1019	bad start time	change start time in runList and rollback
    332661583	16244	silent root errors	rollback ROOT
    339081502	17416	silent root errors	rollback ROOT

  • Code changes:

    directory	script	modification
    commonTools/00-01-00	repTools.py	added new getKey() function to extract #events from FITS event files
    <ac:structured-macro ac:name="unmigrated-wiki-markup" ac:schema-version="1" ac:macro-id="36a90194ef93ae37-4c57e0c9-4cb34df4-b7569205-e5719ca8fc8711fd7ed7267a"><ac:plain-text-body><![CDATA[	P202-FITS/config	config.py	added os.environ['HEADASNOQUERY']='true' to enable 'ftlist' to run in batch	]]></ac:plain-text-body></ac:structured-macro>
    P202-FITS/config	makeFITS.py	add diagnostic print of #evts in FITS files for each processing sub-step

  • After these actions, the dataCatalog tallies are now consistent:

    Note that the number of events in ELECTRONFT1 files are not currently tallied by the dataCatalog.
• 8/24/2012 - Configure and run backfill through 31 July 2012
• 10/7/2012 - Rollback the following seven streams to fix corrupt FITS files. The makeFT1 app received a large number of ROOT error, but terminated normally. The resulting FT1/LS1 files had multiple symptoms, including one discovered by the FSSC during transfer to them: one EVENT_ID was repeated ~1000 times. Scan of log files uncovered an additional five mergeClumps with these errors.

• 8/8/2012 - Prepare task
• 8/18/2012 - 200 runs complete
• 8/25/2012 - Per Seth and Anders, add five runs and remove two:
  • Add: 238421027, 238489647, 239108423, 239114152, 239208666
  • Remove: 244395837, 244401823
    (Note that removed runs have only been removed from dataCatalog – not from xroot)
    But first, need FT2 files for these five runs!
• 10/19/2012
  • P130-series FT2 files now available for early L&EO period
  • The five runs above were never reprocessed; Seth blesses a new set of 64 runs to take their place
  • Add 64 new runs to runList.txt (generate run list for entire L&EO period, then manually extract the new 64)
  • Begin trickleStream
• 10/20/2012 262 runs complete (Original 200 - two 0244* runs + new 64). Note that only MERIT files for the two removed runs were removed from dataCatalog.

Configuration

Identical with P202-ROOT except for the list of runs to be processed...with one exception: to reprocess the four extra (out-of-order) L&EO runs, disable the event list sort.
