LEAP Accelerate

leap-accelerate is a calibration tool implementing Low-frequency Excision of the Atmosphere in Parallel (LEAP) for low-frequency radio antenna arrays. Leap utilizes GPGPU acceleration for parallel computation across baselines, channels and polarizations and is freely available on GitLab under GPLv2+ License.

leap-accelerate includes:

• leap-accelerate: a shared library for gpu accelerated direction centering and phase calibration.
• leap-accelerate-cli: a CLI interface for I/O datastream or plasma data access.
• leap-accelerate-python: python3 bindings to leap-accelerate using pybind11.

See the online documentation for more information.
