  • A Load Balancing Library (ALL)

    The library aims to provide an easy way to include dynamic domain-based load balancing into particle based simulation codes. The library is developed in the Simulation Laboratory Molecular Systems of the Jülich Supercomputing Centre at Forschungszentrum Jülich.

    Only a brief summary is given here and more information can be found in the official documentation such as a detailed API description, examples and further information regarding the load balancing methods.

    Installation and Requirements

    Requirements

    Base requirements:

    • C++11 capable compiler
    • MPI support
    • CMake v. 3.14 or higher

    Optional requirements:

    • Fortran 2003 capable compiler (Fortran interface)
    • Fortran 2008 capable compiler (Usage of the mpi_f08 interface)
    • VTK 7.1 or higher (Domain output)
    • Boost testing utilities
    • Doxygen and Sphinx with breathe (Documentation)

    Installation

    1. Clone the library from https://gitlab.version.fz-juelich.de/SLMS/loadbalancing into $ALL_ROOT_DIR.
    2. Create the build directory $ALL_BUILD_DIR some place else.
    3. Call cmake -S "$ALL_ROOT_DIR" -B "$ALL_BUILD_DIR" to set up the installation. To use a specific compiler and Boost installation use: CC=gcc CXX=g++ BOOST_ROOT=$BOOST_DIR cmake [...].
    4. To build and install the library then run: cmake --build "$ALL_BUILD_DIR" and cmake --install "$ALL_BUILD_DIR". Afterwards, the built examples and library files are placed in $ALL_INSTALL_DIR.
