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_v01. The XML configuration is located in lcgeo/SiD/compact/SiD_o1_v01 and the C++ drivers are located in lcgeo/detector/

Browse or check out the code via https://svnsrv.desy.de/websvn/wsvn/General.ddsim/lcgeo

If needed for read access, a new basic account can be registered for anyone, by anyone else who has a grid certificate, at:
https://svnsrv.desy.de/admin/svn

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

Build example:

# [first five steps are one-time only]
svn co https://svnsrv.desy.de/basic/ddsim/lcgeo/trunk 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/sft.cern.ch/lcg/releases/gcc/4.8.4/x86_64-slc6/setup.sh
source /cvmfs/ilc.desy.de/sw/x86_64_gcc48_sl6/v01-17-09/init_ilcsoft.sh
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/ilc.desy.de/sw/x86_64_gcc48_sl6/ILCSoft.cmake ..
# [make you only need to do after you have changed files]
make -j4
make install
# [setup you need to do every time: ]
source ../bin/thislcgeo.sh

Run example for ddsim:

# [assuming you are in the lcgeo directory you created above, but these instructions are for a clean login]
source /cvmfs/sft.cern.ch/lcg/releases/gcc/4.8.4/x86_64-slc6/setup.sh 
source /cvmfs/ilc.desy.de/sw/x86_64_gcc48_sl6/v01-17-09/init_ilcsoft.sh

python example/lcio_particle_gun.py
ddsim --compactFile=SiD/compact/SiD_o1_v01/SiD_o1_v01.xml --runType=batch --inputFile mcparticles.slcio -N=1 --outputFile=testSiD_o1_v01.slcio

Then to look at the output:

dumpevent testSiD_o1_v01.slcio 1

or

anajob testSiD_o1_v01.slcio
