ATHENA

ATHENA installation at HU cluster
  • The most recent ATHENA installation is TopPhys16.0.3.3.3. It is located at ~atlas/athena.
  • The set-up procedure for release 16 is described below.

1. Preparing your account

For details see the ATLAS TWiki.
  1. Create a place for your ATHENA code
    > cd $HOME
    > mkdir cmthome
    > mkdir testarea
    > cd cmthome
    
  2. Run the setup script
    > source /eeh/atlas/athena/16.0.2/CMT/v1r22/mgr/setup.sh [or .csh]
    
  3. Create a requirements file in your cmthome/ directory. Make sure the SITEROOT variable is set correctly. Here is an basic example:
    #---------------------------------------------------------------------
    set DBRELEASE_OVERRIDE 12.9.3
    set CMTSITE STANDALONE
    set KIT /eeh/atlas/athena/
    #set KIT /eeh/mandry/atlas/athena/releases
    set SITEROOT ${KIT}/15.6.13 \
            15.6.13.3   ${KIT}/15.6.13 \
            15.6.13.3.2 ${KIT}/15.6.13 \
            15.6.13.4   ${KIT}/15.6.13 \
            16.0.2      ${KIT}/16.0.2  \
            16.0.2.3    ${KIT}/16.0.2
    
    macro ATLAS_TEST_AREA ${HOME}/atlas/athena/testarea \
            aplusplustest ${HOME}/atlas/athena/aplusplustest
    macro ATLAS_DIST_AREA ${SITEROOT}
    apply_tag projectArea
    macro SITE_PROJECT_AREA ${SITEROOT}
    macro EXTERNAL_PROJECT_AREA ${SITEROOT}
    apply_tag opt
    apply_tag setup
    apply_tag simpleTest
    use AtlasLogin AtlasLogin-* $(ATLAS_DIST_AREA)
    set CMTCONFIG i686-slc5-gcc43-opt
    #---------------------------------------------------------------------
    
    
  4. Configure CMT
    > cmt config
    
  5. Copy the fixpython script into your cmthome/ folder
    #
    # Fix the PYTHONPATH variable which his wrongly set by ATHENA/
    # Remove  /usr/lib/python from the list of paths
    #
    export PYTHONPATH=`echo $PYTHONPATH | sed s/":\/usr\/lib\/python"/""/`
    

2. Everyday setup

  1. Setup the ATHENA release your are going to use by typing
    > source ~/cmthome/setup.sh -tag=16.0.2    [or .csh]
    
    or for a production release like 15.6.9.13
    > source ~/cmthome/setup.sh -tag=AtlasProduction,16.0.2.3    [or .csh]
    
  2. Sometime you have to run 'source fixpython' also before source setup.sh -tag=... .

  3. Fix the PYTHONPATH variable which is wrongly set by ATHENA.
    > source fixpython
    
  4. Using a different DB release version like 10.7.1
    type in your shell before you setup athena:
    export DBRELEASE_OVERRIDE=10.7.1
    
    and then follow up with step. For a permanent solution you could also add the line
    set DBRELEASE_OVERRIDE 10.7.1
    
    to the top of your requirement file.


3. Setup for Release 16

For release 16 the cmt directory is not needed any more. The set-up procedure is done with the help of the asetup

cpmmand, e.g.

source /users/eeh/atlas/athena_user/cmthome/fixpython                                                                      
export AtlasSetup=/eeh/atlas/athena/16.0.3/AtlasSetup                                                                     
source $AtlasSetup/scripts/asetup.sh TopPhys,16.0.3.3.3 --multi testarea=${HOME}/atlas/athena/testarea/                    
source /users/eeh/atlas/athena_user/cmthome/fixpython 
export ATLAS_POOLCOND_PATH=/afs/cern.ch/atlas/conditions/poolcond/catalogue

 

4. Athena Tools

  • checkFile.py: print the container of a sample
  • checkTrigger.py: print how many events passed the different Trigger Chains
  • dump-athfile.py: print the meta data of a sample

 

5. Kit Installation (admins only)

source /afs/cern.ch/atlas/software/pacman/pacman-latest/setup.sh
cd 16.0.3
pacman -lc am-CERN | tee list
source ./cmtsite/setup.sh -tag=16.0.3
pacman -get am-CERN:TopPhys_16_0_3_3_3_i686_slc5_gcc43_opt
  • From time to time it might be necessary to update the database release. Check the release page  for the needed DBRelease. Update with
pacman -get am-CERN:DBRelease-13.7.1
