OpenEdge

A kinetic transport package for plasma-material and plasma-wall interactions.

OpenEdge evolves neutrals, impurity ions, and dust/droplets in prescribed plasma and magnetic backgrounds, with surface and volume interactions (sputtering, reflection, recycling, ionisation, recombination, CX, dissociation). Used for edge / SOL transport studies, PMI / PWI workflows, and plasma-wall.

Build

CPU build (MPI):

git clone https://github.com/ORNL-Fusion/OpenEdge.git
mkdir buildOpenEdge && cd buildOpenEdge
cmake -C ../OpenEdge/cmake/presets/mpi.cmake ../OpenEdge/cmake -DPKG_OPENEDGE=ON
make -j$(nproc)

Produces ./src/spa_mpi.

GPU build (Kokkos + CUDA):

mkdir buildOpenEdge_gpu && cd buildOpenEdge_gpu
cmake -C ../OpenEdge/cmake/presets/kokkos_cuda.cmake ../OpenEdge/cmake \
    -DPKG_OPENEDGE=ON -DPKG_KOKKOS=ON \
    -DKokkos_ENABLE_CUDA=ON -DKokkos_ARCH_AMPERE80=ON
make -j$(nproc)

Set Kokkos_ARCH_* to your GPU (AMPERE80, HOPPER90, VOLTA70, PASCAL60).

Run a case

CPU (MPI):

cd OpenEdge/examples/test_west_axi
mpirun -np 8 ../../../buildOpenEdge/src/spa_mpi -in in.west

GPU (Kokkos + CUDA, one rank per GPU):

mpirun -np 1 ../../../buildOpenEdge_gpu/src/spa_mpi \
    -k on g 1 -sf kk -in in.west

Outputs (log, dumps, surface tallies) land in the case directory. See each examples/*/README.md for case-specific post-processing.

Requirements

• CMake >= 3.18, C++17 compiler (GCC, Clang, ICC)
• HDF5 with C++ bindings (+MPI for distributed runs)
• MPI (OpenMPI or MPICH)
