dpa

Distributed particle advector based on TBB and MPI.

Requirements

• CMake 3.15+
• Git 2.24+
• GCC 9+ or Visual Studio 2019+

(Manual) Dependencies

• Intel MKL
• Open or Microsoft MPI
• The rest are downloaded automatically through vcpkg.

Building:

• Clone the repository.
• Run bootstrap.[sh|bat]. It takes approximately 20 minutes to download, build and install all dependencies.
• The binaries are then available under the ./build folder.
• Run as mpiexec -n [NUMBER_OF_NODES] -ppn 1 ./dpa [PATH_TO_CONFIG_FILE]. See the utility directory for example config files.

Notes:

• The input must consist of a 1D float spacing attribute and a 4D XYZV float dataset specified in the config file.
• The output is generated as one HDF5 file per rank, each consisting of three entries per round; two 1D float arrays for the vertices/colors and a 1D uint32/uint64 array for the indices.
• The HDF5 files are accompanied by one XDMF file per rank.
• When recording curves, if particles_per_round * iterations > maximum uint32_t, uint64_t indices are used.
