To actually run some jobs it is necessary to call the createStream function of the pipeline. The easiest way to do this is to use the pipeline createStream command when logged in to SLAC unix (e.g. noric).

~exodata/pipeline/prod/pipeline createStream [-options] <taskname> [file1 [file2 [...]]...]

...
--stream <Stream ID=-1> | Integer stream identifier. Auto assigned if option not specified. | |
--nStreams <Number of Streams=1> | Number of streams to create, not valid if Stream ID specified | |

For example to create 10 streams of the EXOMCBackground task defined above, overriding the default value of the MAXEVENTS variable we would use the following command:

~exodata/pipeline/prod/pipeline createStream ---define MAXEVENTS=100000 --nStreams 10 EXOMCBackground |

The pipeline web interface can be access from the EXO data portal at:
http://exo-data.slac.stanford.edu/
The web interface allows monitoring of the status of tasks and streams, viewing the log files of running or completed jobs and "rolling back" (rerunning) any failed jobs. It is also possible to view plots of how much CPU time jobs took, how much many jobs were running at a given time etc.
...
To create a pipeline task it is necessary to write an XML configuration file. The key elements of the XML configuration file for the task above (with some details initially left out) are shown here:
Code Block | ||||
---|---|---|---|---|

Now lets look at the parts which we initially missed out. First the body of the batch job, which by default is written as a bash script:
Code Block | ||||
---|---|---|---|---|

ulimit -c ${CORE_LIMIT} # Limit core dumps set -e # exit on error # Create a scratch area to write the output to export SCRATCH_DIR=/scratch/exo/${PIPELINE_PROCESSINSTANCE} mkdir -p ${SCRATCH_DIR} gotEXIT() { rm -rf ${SCRATCH_DIR} } trap gotEXIT EXIT source ${EXOBASE}/setup.sh # Create background.exe cat > background.exo <<EOF use exosim rec toutput /exosim/macro background.mac /exosim/filter true printmodulo ${PRINTMODULO} /exosim/initial_seed ${INITIALSEED} /exosim/run_number ${PIPELINE_STREAM} maxevents ${MAXEVENTS} /toutput/file ${SCRATCH_DIR}/output.root begin exit EOF case ${SOURCE_ION} in k) GPS_ION="19 40 0 0" ;; th) GPS_ION="90 232 0 0" ;; u) GPS_ION="92 238 0 0" ;; *) echo "Unknown ION ${SOURCE_ION}" exit 1 esac case ${SOURCE_VOLUME} in HFE) HALFZ=72.5 RADIUS=75.0 ;; InnnerCryo) HALFZ=74.5 RADIUS=78.0 ;; *) echo "Unknown volume ${SOURCE_VOLUME}" exit 1 esac # Create background.mac cat > background.mac <<EOF /digitizer/wireNoise 800.000000 /digitizer/APDNoise 2000.000000 /digitizer/LXeEnergyRes 0.015000 /event/LXeEventsOnly true /event/digitizeWires true /event/digitizeAPDs true /gps/pos/type Volume /gps/pos/shape Cylinder /gps/pos/halfz ${HALFZ} cm /gps/pos/radius ${RADIUS} cm /gps/pos/centre 0.0 0.0 0.0 cm /gps/pos/confine ${SOURCE_VOLUME} /gps/energy 0 keV /gps/particle ion /gps/ion ${GPS_ION} /grdm/analogueMC 1 EOF EXOAnalysis background.exo mkdir -p ${OUTPUT_DIR} cp -pv ${SCRATCH_DIR}/output.root ${OUTPUT_FILE} |
...
Finally lets look at the body of the scriptlet which is used to register the output dataset. The scriptlet is written in python:
Code Block | ||||
---|---|---|---|---|
| ||||
metaData = {'nGeneratedEvents':MAXEVENTS,'SourceVolume':SOURCE_VOLUME,'SourceIon':SOURCE_ION}
dsNew = datacatalog.newDataset(OUTPUT_NAME, "root", "EXOROOT", DATACAT_DIR, DATACAT_GROUP, "SLAC", OUTPUT_FILE)
datacatalog.registerDataset(dsNew, metaData)

Note that each file to be uploaded must have a unique task name and version number, so when uploading new version of a task it is necessary to increment the version number in the <task> element. Once a task has been uploaded, an associated job will not start until you issue a "createStream" command (see Running Jobs section above).
