### Compile on Raspberry Pi

#### Install required packages
```bash
sudo apt install cmake 
sudo apt install libfftw3-dev libfftw3-doc
sudo apt install -y python3-grpcio python3-grpc-tools
```

#### Build ExaDiS/KOKKOS
```bash
cd ${OPENDIS_DIR}
rm -rf build/; ./configure.sh -DSYS=rpi
cmake --build build -j 8 ; cmake --build build --target install
```

Alternatively, you can also copy ``cmake/sys.cmake.rpi`` file to ``cmake/sys.cmake.ext`` and configure without -DSYS .  The ``cmake/sys.cmake.ext`` file is not tracked by git so you can feel free to experiment with the settings.

```bash
cp cmake/sys.cmake.rpi cmake/sys.cmake.ext
rm -rf build/; ./configure.sh 
cmake --build build -j 8 ; cmake --build build --target install
```

When compilation is successful, you should see a file like ``pyexadis.cpython*.so``  in the ``core/exadis/python`` folder. 

#### Run test case (OMP version)

```bash
export OMP_NUM_THREADS=8
cd ${OPENDIS_DIR}
cd examples/02_frank_read_src
python3 -i test_frank_read_src_exadis.py
```
