P118 Reprocessing

status: Complete
last update: 25 May 2011

This page is a record of the configuration for the P118 reprocessing project, recalculating diffuse response with new P6_V11 IRFs and adding to existing FT1 files. This processing will be applied to all science data, be incorporated into Level 1 processing, and results sent to the FSSC.

  • P118-FT1 - this task will read existing FT1 (photons) files and emit new FT1 files

Datafile names, versions and locations

Data file version numbers for this reprocessing will begin with v118.

XROOT location and file naming

Location template:

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

Locations for P118:

/glast/Data/Flight/Reprocess/P118/ft1

File naming:

Data Type

Naming template

FT1

Yes

gll_ph_p<procVer>_r<run#>_<version>.fit

Note: 'procVer' is a field added to the file name (and the keyword "PROC_VER" in the primary header) added to the FFD (.doc, or PDF) on 5/12/2010.

Example:

/glast/Data/Flight/Reprocess/P118/ft1/gll_ph_p118_r0239559565_v118.fit
/glast/Data/Flight/Reprocess/P118/ls1/gll_ev_p118_r0239559565_v118.fit
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/P118:FT1 r0239557414
Data/Flight/Reprocess/P118:LS1 r0239557414

Data Sample

The data sample for P118 reprocessing includes the current definition of the "Public_v2" dataset.

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=P118
    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

P118-FT1

(This task is, in configuration, equivalent to the P116-FT1 task, bypassing all but the gtdiffrsp step.)

Note on 'Code Variant': The SLAC batch farm contains a mixture of architectures , both hardware (Intel/AMD 64-bit) and software (RedHat Enterprise Linux 4, and 5, gcc 3.4, 4.1, etc.). Currently, all batch machines have 64-bit hardware and (most, if not all) run with the 64-bit operating systems.

Timing

The execution of gtdiffrsp happens in the mergeClumps step and takes ~5 hequ-minutes per run (on average) to complete. Some individual runs (few percent) take considerably longer...up to 2 hours.
(update 5/25/2011) Statistics for mergeClump now show mean time of 14.4 CPU minutes (averaged across all CPU types, but mostly hequ and boer)
