Local analysis – Local analysis with tags II

May 25, 2007 16

Open your local $HOME/AliEn/Tags/CreateTags.C file and modify it accordingly:

Change the line where you define where you have the locally stored ESDs.

Run the runTagCreator.C macro to create the tag files with alienroot.

Delete the single tag files and stay with just the merged one.

Go to your local $HOME/AliEn/Local/ESD directory and open the demoLocal.C file.

Change the line where you define the location of the tag files and run the runESDAnalysis.C macro with alienroot.

Impose some selection criteria and rerun the example.

Local analysis – Try it out I

May 25, 2007 17

Go to your local $HOME/AliEn/Local/Kine directory and open the demoLocal.C file.

Change the line where you define the location of the tag files and run the runKineAnalysis.C macro with aliroot.

Impose some selection criteria and rerun the example.

Interactive analysis – Using the tags

May 25, 2007 19

Copy the following AliEn files to your local $HOME/AliEn/Interactive/ESD:

/alice/cern.ch/user/p/pchrist/Tutorial/INTERACTIVE/ESD/runESDAnalysis.C

/alice/cern.ch/user/p/pchrist/Tutorial/INTERACTIVE/ESD/demoInteractive.C

You should also get the ESD.par, ANALYSIS.par, AliAnalysisTaskPt.h and

AliAnalysisTaskPt.cxx from the directory of the previous exercise (you

already have them locally).

Go to your local $HOME/AliEn/Interactive/ESD directory and open the demoInteractive.C file.

Change the line where you define the tag collection and put the name of the file you created by querying the f.c (it should be tag.xml).

Run the runESDAnalysis.C macro with alienroot – Impose some selection criteria and rerun the example.

Batch analysis – Analysis flow with tags

May 25, 2007 23

Batch analysis – Creating a new xml file


AliRauTagCuts *RunCuts = new AliRunTagCuts();AliEventTagCuts *EvCuts = new AliEventTagCuts();EvCuts->SetMultiplicityRange(0,1500);

AliTagAnalysis *TagAna = new AliTagAnalysis();TagAna->ChainGridTags(TagResult);

TagAna->CreateXMLCollection(“global”,RunCuts,EvCuts);

TGrid::Connect("alien://”);

TAlienCollection* coll = TalienCollection::Open("tag.xml");TGridResult* TagResult = coll->GetGridResult("”,0,0);

The old xml collection (tag.xml) has information about the tag files that are qoing to be queried.The new xml collection (global.xml) has information about the ESDs that are going to be analyzed.

You need to use the tags in a batch session because:

They reduce your analysis time which allows you to lower your TTL (see next slides) and thus make sure that your job starts early enough (jobs are ordered by TTL). They provide the analyzed data in the proper format (TChain + TEntryLists) in a totally transparent way.

May 25, 2007 24

ExecutableIt should launch root in case you analyze ESDs.

It should launch aliroot in case you access the Kinematics.root as well.

Par fileEffective in case you read ESDs

Not needed in case you need to access the MC “truth”.

Batch analysis - Executable

May 25, 2007 26

Batch analysis - Macro

Setup the par file (in case you read ESDs only) – compile and load the libESD.so (or any necessary library that is needed for the analysis).

Get the xml collection.

Convert the collection to a list of files.

Process the chain with the selector or an AliAnalysisManager.

May 25, 2007 27

Executable: Compulsory field where we give the lfn of the executable that should be stored in /bin or $V0/bin or $HOME/bin.

Arguments: They will be passed to the executable.

Packages: Type packages in the shell to see what kind of packages are installed.

InputFile: The files that will be transported to the node where the job will run.

InputData: It will require that the job will be executed in a site close to the files specified here.

InputDataList: The filename in which the Job Agent will write the InputData list.

InputDataListFormat: The format of the InputData list.

Batch analysis – JDL fields I

May 25, 2007 28

OutputFile: The files that will be registered in the catalog once the job finishes.

OutputArchive: What files will be archived in a zip file.

Validationcommand: Specifies the script to be used as a validation script.

Email: Receive a mail when the job finishes.

TTL: The maximum run time of your job.

Split: Split the jobs in several sub jobs.

Batch analysis – JDL fields II

May 25, 2007 29

Batch analysis – Job status

May 25, 2007 30

If everything is ok with your jdl then your job is submittedand a <JOBID>.is assigned to it.You get a submission error message if:i)a file listed in the jdl is missingii)a package defined in the jdl is not listed in the packman

May 25, 2007 34

Batch analysis – Checking the job output I

May 25, 2007 35

Batch analysis – Checking the job output II

May 25, 2007 36

The output of every splited job is listed under:

/proc/$username/$JOBID if the OutputDir is not defined in the jdl.

OutputDir if it is defined in the jdl.

In order to merge the several output files you have to run a post process:

You can find the macro that deals with this under /alice/cern.ch/user/p/pchrist/Tutorial/BATCH/histomerge.C

[bash]$ alienroot

root [0] .L histomerge.C

root [1] histomerge($OutputDirPath,$pattern,$mergefile)

Batch analysis – Merging the output

OutputDir: is the output directory of the master job (jdl)

Pattern: the zip file that you create in your selector

Mergefile: the desired locally stored merge file

May 25, 2007 37

Copy the following AliEn files to your local

$HOME/AliEn/Batch:
