Grid Services

Grid User Interface

Every PPE SL4x desktop can act as a EGEE gLite UI. The User Interface (UI) tools, dq2-client and GANGA are installed in /data/ppe01/sl44/i386/grid

Using the UI

Check your current shell

echo $SHELL 

If you are using bash or zsh then

source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.sh 

If you are using tcsh or csh then

source /data/ppe01/sl44/i386/grid/glite-ui/latest/external/etc/profile.d/grid-env.csh 

Using the dq2-client

Setup the UI as mentioned in the previous section.

If you are using bash or zsh then

source /data/ppe01/sl44/i386/grid/dq2-client/setup.sh 

If you are using tcsh or csh then

source /data/ppe01/sl44/i386/grid/dq2-client/setup.csh 

Then create a voms proxy

voms-proxy-init -voms atlas 

and use the dq2 Tools as needed. #

Now try these simple commands:

dq2-ls alpgen.105762.ttbarlnlnNp2_lowQ

and to show the individual files (This may not work on SL5 machines)

dq2-ls -f alpgen.105762.ttbarlnlnNp2_lowQ

Using GANGA for ATLAS

then follow the Physics Analysis Workbook (Batch 2) https://twiki.cern.ch/twiki/bin/view/AtlasProtected/PhysicsAnalysisWorkBookBatch2

and https://twiki.cern.ch/twiki/bin/view/Atlas/FullGangaAtlasTutorial

Using GANGA

Setup the UI as mentioned in the previous section.

If you are using bash or zsh then

source /data/ppe01/sl44/i386/grid/ganga/setup.sh 

If you are using tcsh or csh then

source /data/ppe01/sl44/i386/grid/ganga/setup.csh
