<p># Installing AraSim on OSC</p> <p>Readding this because I realized it was deleted when I went looking for it <img alt="laugh" height="23" src="https://as-phy-radiorm.asc.ohio-state.edu/elog/ckeditor/plugins/smiley/images/teeth_smile.png" title="laugh" width="23" /></p> <p>Quick Links:<br /> - https://github.com/ara-software/AraSim # AraSim github repo (bottom has installation instructions that are sort of right)<br /> - Once AraSim is downloaded: AraSim/UserGuideTex/AraSimGuide.pdf (manual for AraSim) might have to be downloaded if you can't view pdf's where you write code</p> <p>Step 1: <br /> We need to add in the dependancies. AraSim needs multiple different packages to be able to run correctly. The easiest way on OSC to get these without a headache is to add the following to you .bashrc for your user.</p> <p>cvmfs () {<br />     module load gnu/4.8.5<br />     export CC=`which gcc`<br />     export CXX=`which g++`<br />     if [ $# -eq 0 ]; then<br />         local version="trunk"<br />     elif [ $# -eq 1 ]; then<br />         local version=$1<br />     else<br />         echo "cvmfs: takes up to 1 argument, the version to use"<br />         return 1<br />     fi<br />     echo "Loading cvmfs for AraSim"<br />     echo "Using /cvmfs/ara.opensciencegrid.org/${version}/centos7/setup.sh"<br />     source "/cvmfs/ara.opensciencegrid.org/${version}/centos7/setup.sh"<br />     #export JUPYTER_CONFIG_DIR=$HOME/.jupyter<br />     #export JUPYTER_PATH=$HOME/.local/share/jupyter<br />     #export PYTHONPATH=/users/PAS0654/alansalgo1/.local/bin:/users/PAS0654/alansalgo1/.local/bin/pyrex:$PYTHONPATH<br /> }</p> <p><br /> If you want to view my bashrc<br /> - /users/PAS1977/jacobweiler/.bashrc</p> <p>Reload .bashrc<br /> - source ~/.bashrc</p> <p>Step 2:<br /> Go to directory that you want to put AraSim and type: <br /> - git clone https://github.com/ara-software/AraSim.git<br /> This will download the github repo</p> <p>Step 3:<br /> We need to use make and load sourcing<br /> - cd AraSim<br /> - cvmfs<br /> - make<br /> wait and it should compile the code </p> <p>Step 4:<br /> We want to do a test run with 100 neutrinos to make sure that it does actually run<br /> Try: - ./AraSim SETUP/setup.txt<br /> This errored for me (probably you as well) <br /> Switch from frequency domain to time domain in the setup.txt<br /> - cd SETUP<br /> - open setup.txt <br /> - scroll to bottom<br /> - Change SIMULATION_MODE = 1<br /> - save<br /> - cd .. <br /> - ./AraSim SETUP/setup.txt <br /> This should run quickly and now you have AraSim setup!</p> Encoding: HTML ELCode plain Suppress Email notification
