COMPOSE: Compact multi-moment performance-portable semi-Lagrangian methods

COMPOSE provides libraries for semi-Lagrangian transport and, together or separately, property preservation:

  • CEDR: Communication-Efficient Constrained Density Reconstructors.
  • SIQK: Spherical Polygon Intersection and Quadrature.

Building and installing

First, install Kokkos. For example, in a typical environment using OpenMP, run:

    git clone https://github.com/kokkos/kokkos.git
    ./kokkos/generate_makefile.bash --with-serial --with-openmp --prefix=/path/to/my/kokkos/install --compiler=g++
    make -j8 install

Second, configure, build, and test COMPOSE:

    cmake \
        -D Kokkos_DIR=/path/to/my/kokkos/install \
        -D CMAKE_INSTALL_PREFIX=/path/to/my/compose/install \
        /path/to/compose/repo
    make -j8
    ctest

Optionally, third, install COMPOSE:

    make install
