Getting Started with SiD DD4HEP

At the moment, our code is committed to the DESY SVN repository, where the core DD4hep software and the CLIC and ILD models are stored as well. This is to make it easier to include SiD in the standard tests. The latest/work version is labelled SiD_o1_v03. The XML configuration is located in lcgeo/SiD/compact/SiD_o1_v01 and the C++ drivers are located in lcgeo/detector/

We are running on SL6 machines and haven't tried other architectures. Note that you must have cvmfs installed (ask your local sysadmin).

Latest update: 5 Sept 16, using the latest ilcsoft release v01-17-10 for everything

Build example:

# [first five steps are one-time only]
svn co lcgeo
rm lcgeo/detector/calorimeter/SHcal*
rm lcgeo/detector/calorimeter/SEcal*
rm lcgeo/detector/CaloTB/CaloPrototype*
mkdir lcgeo/build
# [setups you do every time: ]
source /cvmfs/
source /cvmfs/
cd lcgeo/build
# [cmake you only need do after you have added/removed/moved files from the directories]
cmake -DCMAKE_CXX_COMPILER=`which g++` -DCMAKE_C_COMPILER=`which gcc` -C /cvmfs/ ..
# [make you only need to do after you have changed files]
make -j4
make install
# [setup you need to do every time: ]
source ../bin/

Run example for ddsim:

# [assuming you are in the lcgeo directory you created above, but these instructions are for a clean login]
source /cvmfs/ 
source /cvmfs/
export LCGRELEASES=/cvmfs/
export PYTHONDIR=/cvmfs/
export PATH=/cvmfs/$PATH
export PYTOOLSDIR=/cvmfs/
source bin/
python example/
ddsim --compactFile=SiD/compact/SiD_o1_v01/SiD_o1_v03.xml --runType=batch --inputFile mcparticles.slcio -N=1 --outputFile=testSiD_o1_v03.slcio

Then to look at the output:

dumpevent testSiD_o1_v03.slcio 1


anajob testSiD_o1_v03.slcio

To run reconstruction:

# [assuming you are in the lcgeo directory you created above, but these instructions are for a clean login]
source /cvmfs/
#use the latest SiDReconstruction.xml attached to this twiki page,
#  where you have edited the LCIOInputFiles and DD4hepXMLFile parameters for your local area.
#  You also need to have the basic gear_sid.xml file (attached to this twiki page) in your directory.
