Directories:

  • Incoming
    1. /nfs/farm/g/glast/u23/ISOC-flight/Archive /fcopy -> /sdf/group/fermi/n/u23/ISOC-flight/Archive/fcopy : incoming fastcopy
    2. /nfs/farm/g/glast/u23/ISOC-flight/Archive/level0 -> /sdf/group/fermi/n/u23/ISOC-flight/Archive/level0 : incoming raw data.  Both dirs were copied to s3df April 26, 2023. That's why tests on dev are done with runs of April1, 2023.
  • Still before HalfPipe
    1. RetDef files in /sdf/group/fermi/a/isoc/flightOps/volumes/vol5/offline/halfPipe/v7r0p0_devel/u42/ISOC-flight/Downlinks/<dl>/ . Temporary, was /nfs/farm/g/glast/u42/ISOC-flight/Downlinks/<dl>/ .  These files typically have time stamps of some dozens of seconds before the submission of the HalfPipe stream.  Which process creates these files?  We should ask Don!
    2. du of u42 (in MB):
                722940    ISOC
          713       ISOC-devel
          2530798   ISOC-flight
            538211    ISOC-flight/Downlinks
            1974982   ISOC-flight/FswDumps
            17726     ISOC-flight/Online
          1075      ISOC-nightly
          16641     ISOC-test
          3272165    total
      1. 2 TB of FswDumps. What's that? Does someone care?
      2. We would prefer to have u42/ISOC-flight/Downlinks copied to s3df. It contains the downlink dirs since launch, a fee transient dirs, and an evt dir. In evt are some evt files whose role isn't clear, we shouldn't loose them.
  • During/after HalfPipe
    1. /sdf/group/fermi/a/isoc/flightOps/volumes/vol5/offline/halfPipe/v7r0p0_devel/u28/stage : staging directory, defined in config/stagedir

Processes:

  • launchChunks: is just an embedded jython scriptlet launching a stream for every chunk: for i in range(0, numChunks): pipeline.createSubstream("doChunk", i+1)
  • doChunk.makeEvt.sh
    • each makeEvt creates identical lock files ${HALFPIPE_OUTPUTBASE}/lock/halfpipe-${HALFPIPE_DOWNLINKID} .  Have to check when this file is being removed.
    • RetDef files $HALFPIPE_OUTPUTBASE/$HALFPIPE_DOWNLINKID/RetDef-$HALFPIPE_DOWNLINKID-$HALFPIPE_CHUNKID.xml are missing.  u42 isn't on s3df.  We copied these files from rhel6-64:/nfs/farm/g/glast/u42/ISOC-flight/Downlinks/<dl>/ .
  • mergeIndices.sh
    • tokendir is read dinamically: tokendir=`cat ${taskBase}/config/stagedir`/chunktokens . For testing we changed stagedir from /nfs/farm/g/glast/u28/stage to /sdf/group/fermi/a/isoc/flightOps/volumes/vol5/offline/halfPipe/v7r0p0_devel/u28/stage .
    • at the end a mergeEvt stream for each run is created.  This won't work in the container.  This task is being taken by launchMerge , an embedded scriptlet in the xml.
  • launchMerge: embedded scriptlet to launch mergeEvt
  • mergeEvt.sh
    • should receive ${HALFPIPE_RUNSTART} from launchMerge.  Doesn't work right now.  Workaround: read the decimal runid from PIPELINE_STREAM and convert to hex.  Michael thinks this should be safe.
    • not fault of mergeEvt, I guess: mergeEvt runs always on sdfmilan11[56].  There is no /lscratch but /scratch /lscratch needed --bind and /sdf/group/fermi/a/isoc/flightOps/volumes/vol5/offline/halfPipe/v7r0p0_devel/outputBase is mapped to uid 7234 , while glastraw is 9503 .  Ticket open. Michael's fault.  7234 is Omodei, glastraw is 9503.  All ok.
    • Michael did something else yesterday to make mergeEvt finish.  But probably the above should be understood and fixed first.
  • launchL1
    • should work (I (Nicola) haven’t added the "submit" script yet, but it gets to the point where it call the “submit stream” command successfully created.
    • launchL1 creates streams of task intOnlineAnalysis.  It seems to deal with calibration runs.  The last time an intOnlineAnalysis stream finished successfully was 2013, the last partial 2017!  We have to figure out if this task has any use, needs to be fixed, or simply can be skipped.
  • launchOnline: there is still the question about the “evt” directory… we need to check on the rhel6 who is making this dir and how it is used? We also have multiple directories called “stage” (one in  /sdf/group/fermi/a/isoc/flightOps/volumes/vol5/offline/halfPipe/v7r0p0_devel/u28/stage/  one in  /sdf/group/fermi/a/isoc/flightOps/volumes/vol5/offline/halfPipe/v7r0p0_devel/outputBase/stage/  we probably need a bit of cleaning.
