Installation - hyschive/gamer-fork GitHub Wiki

  1. Set up the machine configuration file

    Please see Machine Configuration File.

  2. Go to the source directory

    cd src

  3. Generate Makefile using the Python script configure.py

    To get the Makefile, please execute the following command:

    python configure.py --machine=your_configuration_file [--your_arguments]

    your_configuration_file is the configuration filename you got from step 1, and [--your_arguments] should match your simulation requirements. Please check out Option List for all the available options.

    For example, the following command uses the configs/pleiades.config machine configuration, sets the FFTW method to FFTW2, and enables gravity and GPU.

    python configure.py --machine=pleiades --fftw=FFTW2 --gravity=true --gpu=true

Tip

An example script generate_make.sh to generate Makefile can be found in each test problem folder, e.g., example/test_problem/Hydro/AcousticWave/generate_make.sh.

  1. Compile the code

    make clean
make

Tip

To reduce the compilation time, you can perform a parallel compilation by make -j N, where N is the number of compilation jobs to run in parallel. For example, the following command will invoke 4 compilation jobs simultaneously:

make -j 4

However, please consult the documentation of your system to avoid violating the usage policy.

If the compilation succeeds, you will see the following message

Compiling GAMER --> Successful!

and get an executable gamer, which will be automatically copied to ../bin/gamer.
