Features

ppkMHD is a C++ CFD application framework designed with the performance portability library kokkos. The code can run on a laptop as well as on a cluster of GPUs (e.g. ouessant at IDRIS (IBM Power8 + Nvidia P100))

Here is a short list of numerical features:

• 2nd order MUSCL/Hancock for compressible hydrodynamics and MHD (same as in RamsesGPU. )
• high-order MOOD schemes (hydrodynamics only)
• high-order spectral difference method (SDM) schemes with positivity preserving and limiter

Future versions may include adaptive mesh-refinement by interfacing p4est library.

• CPU only AMR code is CanoP
• Prototype AMR Kokkos code is khamr

Install

System requirements

Supported platform

• linux
• Mac

Software requirements

• CMake
• optional Doxygen for documentation
• optional : an MPI compiler (e.g. OpenMPI, MPVAPICH). If you intend to use this software on a GPU cluster, please cross-check your MPI implementation is cuda-aware (might need to re-compile or ask your sysadmin).

Please note that library kokkos is automatically downloaded and built as part of ppkMHD. kokkos source directory is populated using a git submodule.
