Set up the machine configuration file

Please see Machine Configuration File.

Set your machine configuration file as default

sh tool/config/set_settings.sh --local --machine=your_machine

Note

If you want to set the default machine configuration file for all of the GAMER copies under your user account, use the --global option instead of --local. Still, you can override the global setting for the individual GAMER copies with the --local option. Furthermore, you can override the default setting by passing the --machine=your_machine when executing configure.py.

Go to the source directory
```
cd src
```
Generate Makefile using the Python script configure.py

To get the Makefile, please execute the following command:
```
python configure.py [--your_arguments]
```
[--your_arguments] represent the options that should align with your simulation requirements. Please check out Option List for all the available options.

For example, the following command sets the FFTW method to FFTW2, and enables gravity and GPU.
```
python configure.py --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.

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.
