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.

A JIRA was created for these tasks in May 2014. Look to this JIRA's comments for operational details that formerly were included on this page.

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.

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)

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.

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.)

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.
