Astrophysics MHD simulation code optimized for large cluster of GPU
WARNING: This code is mostly deprecated. Have a look at ppkMHD
Magneto Rotational Instability simulation in a shearing box setup (800x1600x800) made in 2013 on TGCC/CURIE using 256 GPUs. Here Reynolds number is 25000 and Prandtl number is 4.

See doxygen-generated documentation in doc sub-directory
Quickstart for building RAMSES-GPU using CMake (recommended)
Default CUDA compilation flags can be passed to cmake using env variable CUDAFLAGS, or directly set CMAKE_CUDA_FLAGS on the configuration command line (see below).
You should get executable ramsesGPU_mpi_cuda. Explore other flag using the ccmake user interface.
sh autogen.sh
Note: make sure to have CUDA toolkit installed, and environment variables PATH and LD_LIBRARY_PATH correctly set.
This will build the monoCPU / monoGPU version of the programme to solve hydro/MHD problems. Executable are located in src subdirectory and named euler_cpu / euler_gpu
Execute a test run:
cd src
./euler_gpu --param ../data/jet2d_gpu.ini
This will start a Hydrodynamics 2D jet simulation run. Output files can be in multiple file format (VTK, Hdf5, ...).
To visualize Hdf5 output, just run:
paraview --data=./jet2d_gpu.xmf
