status: In development
last update: 16 January 2015

This page is a record of the configuration and execution of the P302 reprocessing project, generation FITS files from the P301 MERIT files.

Notice: there is now a JIRA for this task.  Please check here for operational notes.

Pipeline tasks

• P301-MERIT - This task reads P300 MERIT and produces reprocessed MERIT.  This is the first time TMineExt has been used to perform this function.

• P301-FITS - This task reads new P301 MERIT and produces fits files, EXTENDEDFT1 + EXTENDEDLS1

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>

Locations for P301:

/glast/Data/Flight/Reprocess/P301/merit

[soon]
/glast/Data/Flight/Reprocess/P301/ft1
/glast/Data/Flight/Reprocess/P301/extendedft1
/glast/Data/Flight/Reprocess/P301/electronft1
/glast/Data/Flight/Reprocess/P301/ls1
/glast/Data/Flight/Reprocess/P301/extendedls1

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/P301/recon/r0239557414_v301_merit.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:

Data/Flight/Reprocess/P301:MERIT r0239557414

Data Sample

The currently defined data sample (as of 4/18/2014) for P301 reprocessing includes:

Bookkeeping

1. (This page): Define ingredients of reprocessing (processing code/configuration changes)
2. Processing History database: http://glast-ground.slac.stanford.edu/HistoryProcessing/HProcessingRuns.jsp?processingname=P301
   1. List of all reprocessings
   2. List of all data runs reprocessed
   3. Pointers to all input data files (-> dataCatalog)
   4. Pointers to associated task processes (-> Pipeline II status)
3. Data Catalog database: http://glast-ground.slac.stanford.edu/DataCatalog/folder.jsp
   1. Lists of and pointers to all output data files
   2. Meta data associated with each output data product

P301-MERIT

Status chronology

• 3/27/2014 - Begin setting up P301 task for Pass8 re-MERIT.
• 5/5/2014 - Please see the P301 JIRA for future chronology updates
• 6/9/2014 - Begin block 2, through end of April 2014 (see JIRA)
• 6/10/2014 - Block 2 complete
• 10/21/2014 - Begin block 3, through end of September 2014 (see JIRA)
• 10/22/2014 - Block 3 complete
  
  

Configuration

Timing and Scaling

• job step	average CPU time
  TMine	~0.5-1M evts/hour

P301-FITS

This task generates all desired FITS data products.

• A slightly updated task structure has been implemented for this task: the mergeClumps step is now a separate subTask which allows overriding the batch queue parameter for extra long runs.  This restructuring required quite a lot of modification related to data passed between job steps (as now certain job steps are in the new subTask). 
• Task stored in my github as P301-FITS

Status chronology

This task basically mirrors the P301-MERIT task, running after the aforementioned completes

Please see the associated JIRA for operational notes.

Configuration

Generation of output data products:

[1] /afs/slac/g/glast/ground/releases/volume04/evtClassDefs/01-00-01/data

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, RHEL6-64.

Timing and Scaling

Approx 20 CPU minutes and 30 wall clock minutes per job (run).
