**cuDF** is a Python GPU DataFrame library (built on the `Apache Arrow
<https://arrow.apache.org/>`_ columnar memory format) for loading, joining,
aggregating, filtering, and otherwise manipulating data. cuDF also provides a
pandas-like API that will be familiar to data engineers & data scientists, so
they can use it to easily accelerate their workflows without going into
the details of CUDA programming.

``cudf.pandas`` is built on cuDF and accelerates pandas code on the
GPU.  It supports 100% of the pandas API, using the GPU for
supported operations, and automatically falling back to pandas for
other operations.
