<p><b>New page</b></p><div>'''TUESDAY'S OBJECTIVES'''<br />
* Run your Athena job on the grid (this will take your whole day). <br />
''' ATHENA ON THE GRID'''<br />
* Write a batch script which runs your Athena job on the local machine.<br />
* Write the corresponding xrsl file. Submit it to the grid (like described for Monday).<br />
''' Example which compiles on remote cluster :'''<br />
<br />
[shaug@lheppc44] > cat test.sh <br />
#/bin/bash<br />
# /terabig/shaug/atlas<br />
# tar cvf myAnalysis.tar 14.1.0.2/<br />
pwd<br />
<br />
ls -l <br />
env<br />
export CMTPATH=$HOME:$CMTPATH<br />
cd 14.1.0.2/PhysicsAnalysis/AnalysisCommon/UserAnalysisUtils/cmt<br />
source setup.sh<br />
cmt config<br />
gmake<br />
cd<br />
cd 14.1.0.2/PhysicsAnalysis/AnalysisCommon/UserAnalysis/cmt<br />
cmt config<br />
source setup.sh<br />
gmake<br />
cd ../run<br />
athena.py AnalysisSkeleton_topOptions_lowpt.py<br />
<br />
[shaug@lheppc44] > cat athena.xrsl <br />
<br />
&(executable=test.sh)<br />
(inputFiles=("myAnalysis.tar" "myAnalysis.tar"))<br />
(outputfiles=("/" ""))<br />
(stdout=test.log)<br />
(stderr=test.err)<br />
(jobname=sigves-athena)<br />
(runTimeEnvironment=APPS/HEP/ATLAS-14.1.0.2)<br />
<br />
''' Example without compiling remotely :'''<br />
In order to send the compiled job to the grid we have to include the following directory in the gridfiles.tar file <br />
<br />
InstallArea/python<br />
<br />
as well as the libraries (inside InstallArea/i686-slc4-gcc34-opt/lib/*.so)<br />
<br />
libUserAnalysis.so, <br />
libAnalysisUtilsLib.so, <br />
libUserAnalysisUtils.so<br />
<br />
<br />
The resulting tar file will then contain all the custom .so files and the python directory.<br />
<br />
In order to make the system use the custom libraries, one needs to set LD_LIBRARY_PATH (for libraries) and PYTHONPATH (for python bindings):<br />
<br />
(just after the tar -xvzf command)<br />
<br />
cd gridfiles<br />
a=$(pwd)<br />
export LD_LIBRARY_PATH=$a:$LD_LIBRARY_PATH<br />
export LD_LIBRARY_PATH=$a/python:$LD_LIBRARY_PATH<br />
export PYTHONPATH=$a/python:$PYTHONPATH<br />
<br />
<br />
An example bash script which will be executed on the grid: <br />
<br />
#/bin/bash<br />
tar -xvf gridfiles.tar<br />
cd gridfiles<br />
a=$(pwd)<br />
export LD_LIBRARY_PATH=$a:$LD_LIBRARY_PATH<br />
export LD_LIBRARY_PATH=$a/python:$LD_LIBRARY_PATH<br />
export PYTHONPATH=$a/python:$PYTHONPATH<br />
athena.py AnalysisSkeleton_topOptions.py</div>Lhep
