BLINK Imager

A end-to-end GPU-accelerated imager for widefield interferometers.

Dependencies

You will need the following libraries to compile the project.

BLINK libraries:

• astroio

Third-party libraries:

• fftw
• pal
• cfitsio
• libnova
• ROCm or CUDA for a GPU build (optional)
• OpenMP for CPU parallelisation (optional)

Compiling

The compilation process is handled by CMake. To build a CPU only version, do the following:

mkdir build; cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make 

A CUDA enabled build can be obtained by simply adding the -DUSE_CUDA=ON argument to cmake.

To compile the code with HIP support, you will need to specify -DUSE_HIP=ON -DCMAKE_CXX_COMPILER=hipcc.

To run tests, execute make test.

Available CMake flags are:

• USE_OPENMP (default: ON): run the correlation function in parallel on multiple cores.
• USE_HIP (default: OFF): build the library using HIP to enable AMD GPU support.
• USE_CUDA (default: OFF): build the library using CUDA to enable NVIDIA GPU support.
