How to run OpenRadioss

OpenRadioss is made of:

  • OpenRadioss Starter that checks the model and splits the mesh

  • OpenRadioss Engine that runs the simulation in parallel

  • Few libraries (links to github)

  • A set of configuration files (links to github) that describes the input

Running OpenRadioss

Download and build OpenRadioss (links to github), or download the binaries (links to github)

The detailed steps are below, but there are also simplified versions: Simplified Running OpenRadioss and Python/tk guis for running OpenRadioss

Environment variable

export OPENRADIOSS_PATH=[OpenRadioss Root directory] export RAD_CFG_PATH=$OPENRADIOSS_PATH/hm_cfg_files export OMP_STACKSIZE=400m

If you built OpenRadioss from the source

export LD_LIBRARY_PATH=$OPENRADIOSS_PATH/extlib/hm_reader/linux64/:$OPENRADIOSS_PATH/extlib/h3d/lib/linux64/:$LD_LIBRARY_PATH

If you downloaded the binaries from here (github link)

export LD_LIBRARY_PATH=$OPENRADIOSS_PATH/lib/:$LD_LIBRARY_PATH

Running OpenRadioss without MPI (OpenMP only)

  • Define number of OpenMP threads

    export OMP_NUM_THREADS=N

    Run OpenRadioss Starter and Engine from the directory that contains the binaries

    ./starter_linux64_gf -i [Starter input file] -np 1 ./engine_linux64_gf -i [Engine input file]

Running OpenRadioss with MPI+OpenMP

  • Set up environment variables, assuming that OpenMPI is installed in /opt/openmpi

    export LD_LIBRARY_PATH=/opt/openmpi/lib:$LD_LIBRARY_PATH export PATH=/opt/openmpi/bin:$PATH

  • Run OpenRadioss with P MPI process and N threads per domain from the directory that contains the binaries

    export OMP_NUM_THREADS=N ./starter_linux64_gf -i [Starter input file] -np P mpiexec -n P ./engine_linux64_gf_ompi -i [Engine input file]

Running OpenRadioss test suite from the source code

  • Set OpenRadioss Environment variables

    export OPENRADIOSS_SOURCE_PATH=[OpenRadioss Root directory] export RAD_CFG_PATH=$OPENRADIOSS_SOURCE_PATH/hm_cfg_files export LD_LIBRARY_PATH=$OPENRADIOSS_SOURCE_PATH/extlib/hm_reader/linux64/:$OPENRADIOSS_SOURCE_PATH/extlib/h3d/lib/linux64/:$LD_LIBRARY_PATH export OMP_STACKSIZE=400m

  • Go to the qa_test/scripts directory

    cd $OPENRADIOSS_SOURCE_PATH/qa-tests/scripts

Running without MPI (OpenMP only)

perl ./or_qa_script ../../exec/engine_linux64_gf 1.0

Running with MPI (MPI+OpenMP)

  • Set up environment variables, assuming that OpenMPI is installed in /opt/openmpi

    export LD_LIBRARY_PATH=/opt/openmpi/lib:$LD_LIBRARY_PATH export PATH=/opt/openmpi/bin:$PATH

  • Run the test suite with P MPI processes, and N threads per MPI process

    export OMP_NUM_THREADS=N perl ./or_qa_script ../../exec/engine_linux64_gf_ompi --exec_script_args="mpiexec -np P" 1.0
