  3. Part I – Information on pathena

  4. Introduction • PanDA = Production ANd Distributed Analysis system • pathena: Client tool for PanDA • Submits user-defined jobs • A consistent user-interface to Athena users. Works on Athena runtime environment. • Runs at the sites in OSG and LCG. • Requirements to run pathena jobs: • Athena • Any release version • Kit or AFS • GRID User Interface (UI) • LCG UI • VDT • NG UI • Join ATLAS VO • All ATLAS VO members Nurcan Ozturk

  5. How pathena Works - Datasets input dataset (official or user dataset) output dataset (user dataset) • No essential difference between production jobs and analysis jobs. • Analysis jobs run on the same infrastructure as production jobs. The infrastructure is always maintained by the production operations team. • User dataset can be accessed via DDM (using DQ2 end-user tools). • Analysis jobs and production jobs run on separated computing-resources: • Analysis queues: • Short queue (wall-time limit = 90min) • Long queue (wall-time limit = 8 hours) • Analysis jobs don’t have to compete with production jobs. Job (production or analysis) file file transformation file file Nurcan Ozturk

  6. What Type of Jobs pathena Can Run • pathena can run all kinds of Athena jobs: • All production steps • Event generation • Simulation, Pileup • Digitization • Reconstruction • Merge • Analysis • Arbitrary package configuration • Add new packages • Modify cmt/requirements in any package • Customize source code and/or jobOption • Multiple-input streams • For instance signal + minimum-bias • TAG/AANT-based analysis • Protection against corrupted/missing files Nurcan Ozturk

  7. pathena Usage When running athena: $ athena MyJobOptions.py All you need to do is: $ pathena MyJobOptions.py –-inDS inputDataset --outDS outputDataset • Nothing special to submit your Athena job to GRID using pathena. • athena -> pathena • Add inDS and outDS • The user doesn’t have to modify jobOption file when submitting jobs. • Jobs go to data – you need to know where your data is. Analysis jobs don’t trigger data transfer across GRIDs. Nurcan Ozturk

  8. pathena Options pathena [--inDS InputDataset] [--outDS OutputDataset] [--minDS MinimumBiasDataset] [--cavDS CavernDataset] [--split N] [--site SiteName] [--nfiles N] [--nFilesPerJob N] [--nEventsPerJob N] [--nSkipFiles N] [--official] [--extFile files] [--libDS LibraryDataset] [--long] [--blong] [--nobuild] [--memory MemorySize] [--tmpDir tmpDirName] [--shipInput] [--fileList files] [--addPoolFC files] [--skipScan] [--removeFileList filename] [--inputFileList filename] [--inputType types] [-p bootstrap] [-c command] <jobOption1.py> [<jobOption2.py> [...]] Please see what you can do using these options on the twiki page: https://twiki.cern.ch/twiki/bin/view/Atlas/DAonPanda#options Nurcan Ozturk

  9. What Happens When Submitting Jobs builds the athena environment at the remote site. It produces a library dataset. runs athena and produces the output files • archive user's work directory • send the archive to Panda • extract job configuration from jobOs • define jobs automatically • submit jobs Nurcan Ozturk

  10. Monitoring pathena Jobs http://pandamon.usatlas.bnl.gov:25880/server/pandamon/query Nurcan Ozturk

  11. Bookkeeping & Retry • pathena has utilities to see the status/details of the jobs submitted and retry the failed ones for instance: • $ pathena_util >>> show() ====================================== JobID : 8239 time : 2008-04-29 03:29:07 inDS : fdr08_run1.0003051.StreamEgamma.merge.AOD.o1_r6_t1 outDS : user.NurcanOzturk.HighPtView.StreamEgamma.AtlasInAnkara libDS : user.NurcanOzturk.lxplus205_0.lib._008239 build : 10676339 run : 10676340 jobO : -c "Mode=['FullReco'];DetailLevel=['FullStandardAOD'];Branches= ['StacoTauRec']" MyJobOptions.py site : ANALY_SWT2_CPB >>> status(8239) >>> retry(8239) >>> kill(8239) >>> help() • Press Ctl-D to exit Nurcan Ozturk

  12. User Support • PanDA Savannah page – report problems/errors: https://savannah.cern.ch/projects/panda/ • PanDA/pathena hypernews forum: discussions, sharing experience, helping each other: https://hypernews.cern.ch/HyperNews/Atlas/get/pandaPathena.html • See the production shift elog (electronic logbook) for system wide or site level problems, maintenances, outages. It is linked from main PanDA monitor page: http://atlas003.uta.edu:8080/ADCoS/?mode=summary Nurcan Ozturk

  13. Part II - Pathena Tutorial Available at: http://www.usatlas.bnl.gov/twiki/bin/view/AtlasSoftware/PathenaOnFDRData

  14. Goal • Learn how to submit an analysis job: • Setup athena • Check out PandaTools package (for pathena) • Use HighPtView package as an analysis package • Find the data (we will run on FDR data) • Find out which analysis queue will be used • Submit a pathena job • Monitor job’s status in PanDA monitor • Get the output of the job and make plots Nurcan Ozturk

  15. Setup Athena and Work Area • Instructions are given to run on lxplus machines at CERN • Create a directory (called AtlasInAnkara) and get the requirements file from next page • Make a sub-directory for 13.0.40 (called 13.0.40) under AtlasInAnkara • Setup CMT: • source /afs/cern.ch/sw/contrib/CMT/v1r20p20070208/mgr/setup.sh • cmt config • Setup athena for release 13.0.40: • source setup.sh -tag=13.0.40,32,groupArea (32 is complier version gcc323) • Check out Tools/Scripts package to setup your work area (easy way of checking out and compiling multiple packages) • cd 13.0.40 • cmt co -r Scripts-00-01-14 Tools/Scripts • Setup work area and create run area: • ./Tools/Scripts/share/setupWorkArea.py • cd WorkArea/cmt • cmt bro cmt config • cmt bro gmake • source setup.sh Nurcan Ozturk
