RI Kernels

CPU and GPU kernels for radio interferometry, exposed to JAX as FFI custom calls with full support for automatic differentiation.

Installation

The CPU kernels and all of the Python code live in ri_kernels. The GPU kernels ship as add-on packages, one per CUDA major version, selected with an extra:

pip install ri_kernels               # CPU kernels only
pip install "ri_kernels[cuda12]"     # + CUDA 12 kernels and jax[cuda12]
pip install "ri_kernels[cuda13]"     # + CUDA 13 kernels and jax[cuda13]

Building from source

Requires CMake >= 3.20, a C++20 compiler, and network access at configure time (Google Highway is fetched by CMake).

pip install .                      # CPU only
RI_KERNELS_CUDA=1 pip install .    # CPU + CUDA, needs nvcc
RI_KERNELS_ROCM=1 pip install .    # CPU + ROCm, needs hipcc

Both libraries land in the ri_kernels package directory in that case, which is also a location the loader searches. Note that pip install .[cuda12] is a different thing: the extra resolves ri_kernels_cuda12 from the index, so it needs a published release. To build the GPU kernels from the checkout, use RI_KERNELS_CUDA=1.

Other CMake options of note: RI_KERNELS_CPU (default ON), RI_KERNELS_MULTI_ARCH (dynamic SIMD dispatch, default ON — turn it off and set arch flags via CMAKE_CXX_FLAGS for a single-target build), RI_KERNELS_BUNDLED_HIGHWAY, and CMAKE_CUDA_ARCHITECTURES.

Tests

Tests can be run with
