last update: 26 June 2014

This page is a record of the configuration and execution of the P300 reprocessing project, full reprocessing from DIGIs using Pass8 analysis code.

Pipeline tasks

• P300-ROOT - This task reads DIGI and produces reprocessed RECON + GCR + MERIT + FILTEREDMERIT (photons) + ELECTRONMERIT

• P300-FITS - This task will never happen – look for P301-FITS, which reads MERIT and produces FT1 (photons) + EXTENDEDFT1 + LS1 (merit-like FITS file for photons) + EXTENDEDLS1 + ELECTRONFITS file

• An experimental P300x-FITS task is being used for early validation studies. These data will not survive in the long run...
• L&EO data (264 runs) reprocessed with P300-LEO-ROOT and P300x-LEO-FITS

Datafile names, versions and locations

Data file version numbers for this reprocessing will begin with v300.

XROOT location and file naming

Location template:

/glast/Data/Flight/Reprocess/<reprocessName>/<dataType>

File naming:

Note: 'procVer' is a field added to the file name (and the keyword "PROC_VER" in the primary header) added to the FFD 5/12/2010. Ref: http://fermi.gsfc.nasa.gov/ssc/dev/current_documents/Science_DP_FFD_RevA.pdf

Example:

/glast/Data/Flight/Reprocess/P300/recon/r0239557414_v202_recon.root

DataCatalog location and naming

Logical directory and group template:

Data/Flight/Reprocess/<reprocessName>:<dataType>

Note that the <dataType> field (following the colon) is a DataCatalog 'group' name, and file names are of the form r<run#>.

Naming examples:

P300-ROOT

Status chronology

• 4/23/2013 - Begin setting up P300 task for Pass8 reprocessing.
• 5/10/2013 - Initial version of task running.  See this page for infomation about the task creation, and this page for performance comparison with P202
• 7/2/2013 - after weeks of testing, final GR, jobOpts, etc. come together and production tentatively starts.
  • Block 1 is defined with this run range: 239557414 through 392842073 (2008-08-04 15:43:37 through 2013-06-13 18:47:50 UTC)
  • Update task to use the P202 generation of FT2 files (adds columns LAMBDA, RA_SUN, DEC_SUN, as well as meaningful BTIs)
  • First 10 trial jobs launched. Too many ACD INFO messages 'Missed Poca for ID 602 at...' so modify jobOpts to disable.
  • xroot disk space at the start of Pass8 = 508 TB (just after commissioning of fermi-xrd11)
• 7/29/2013 - a new GR is prepared (20-09-01) which fixes some problems in ACD tracking issues affecting ~32 runs so far (out of 5283). trickleStream disabled, wait for pending jobs to start, rollback other failed jobs, switch to new GR, rollback of ACD-failed jobs...
  • This new GR continues to seg fault, so revert back to GR 20-09-00 and restart trickleStream.
• 7/31/2013 - A new GR (20-09-02) with patch for ACD tracking installed after stream 5970. At the time, there were 33 failed processClumps jobs. All rolled back.
  • Last stream with GR 20-09-00 = 5970, run 274118943
  • First stream with GR 20-09-02 = 5971, run 274124672
  • Full list of rolled back substreams is here
• 10/15/2013 - Update job options to use the new "L1current" flavor of calibrations/alignment rather than "p7repro".  First stream with new configuration: 20804.
• 11/14/2013 - Block 1 complete except for routine cleanup

• 11/21/2013 - Block 1 complete
  Problems encountered include:
  ** pipeline_summary file corruption causing loss of email or of it being ignored, finally jobs terminate via reaper (Tony notified)
  ** large blocks of failures due to dataCatalog not returning desired FT2 files (Brian notified, fix possible by moving query to scriptlet)
  ** jobs running out the clock due to anomalously slow xroot behavior (Wilko/Andy notified)
  ** problems with individual batch machines (Renata notified, and I also have the authority to remove batch machines from production)

Create JIRA for this task.  Submit first 50 streams of 'block 2'

• 5/6/2014 - After big Oracle upgrade, regenerate/redefine 'block 2' to contain all runs through April 2014.  This block contains 31838 runs, in increase of 4909 runs, starting with 392848044 and ending with 420590482.  All future routine operational comments will be added tot he JIRA and not to this confluence page.

• 8/2/2015 Emergency reprocess of 40 runs that were Level 1 processed with bad CAL calibrations

  Former (block7) run consisted of 38198 runs.
  New (block8) run consists of 38238 runs.
  There are 40 new runs to reprocess.
  First new run 459716687
  Last new run 459941302
  Starting point of pipeline task P300-ROOT (v1.1): 11269

Configuration

Timing and Scaling

• Current performance results for the Pass8 code are on this page .

• For 20,000 event clumps:

  job step	average CPU time
  processClump	183 min
  mergeClumps	10 min

• Plot of job throughput as of 20130813
  
  From the plot, one can see a processing rate of ~208 runs/day. Assuming 28500 total runs, this would mean a repro time of 137 days or 4.5 months.

P300x-FITS

This task generates all desired FITS data products.

NOTE: a temporary task called P300x-FITS has been created. It generates only EXTENDEDFT1 files and nothing else. There is no diffuse calculation performed. An untagged version of evtClassDefs is used which contains Matthew Wood's initial event classification and selections. This will likely be a template for a future production P300-FITS task. All data produced by this task are "throw-away" and not expected to survive beyond initial validation studies.

Status chronology

• 8/1/2013 - Initial P300x-FITS task created. 10 trial runs processed. (See caveats above.)

• 8/7/2013 - First year of data run through the task, amounting to 5537 runs and 11790391606 events:

  First run	239557417	2008-08-04 15:43:37
  Last run	271850279	2009-08-13 09:57:59

• 8/28/2013 - Second year of data ready and processed -> extendedFT1. Note that 36 troublesome runs omitted from 1st year data were included in this sample. There should be no missing runs in this sample.

  First run	239557417	2008-04-2008 15:43:37
  Last run	302647722	2010-08-04 20:48:40

  10,976 runs, 2,677,747,829 events, 234.7 GB

• 9/25/2013 - Third year of data ready.

  First run	239557417	2008-04-2008 15:43:37
  Last run	334184989	2011-08-04 21:09:47

  This block contains 16,516 runs and 36,056,385,847 events, or an increase over year 2 of 5,540 runs.

• 11/21/2013 - Prepare for final Block 1 backfill.  First run of backfill: 334190716, last run of backfill: 392842073, a total of 10 413 additional runs to process.

• 11/22/2013 - Block 1 is complete.  The P300x area of the dataCatalog reports:

• THIS TASK IS DEFUNCT, replaced by P301-MERIT and P301-FITS

Configuration

CAUTION: The following data describes the experimental P300x-FITS task, not the production task

WARNING: THIS NEXT SECTION IS OBSOLETE

Generation of output data products:

[1] /afs/slac/g/glast/ground/releases/volume04/evtClassDefs/00-19-04/data

Note that diffuse response is calculated for 'source' and 'clean' event classes only.

Note on 'Code Variant': The SLAC batch farm contains a mixture of architectures , both hardware (Intel/AMD 64-bit) and software (RHEL5-64, gcc v4.1, etc.). At this time, GlastRelease builds only on RHEL5-32 (RHEL6-64 are built but not yet validated), while ScienceTools builds for RHEL5-64, RHEL5-64.
