 Dask cuDF - A GPU Backend for Dask DataFrame
+ + Dask cuDF (a.k.a. dask-cudf or `dask_cudf`) is an extension library for [Dask DataFrame](https://docs.dask.org/en/stable/dataframe.html) that provides a Pandas-like API for parallel and larger-than-memory DataFrame computing on GPUs. When installed, Dask cuDF is automatically registered as the `"cudf"` [dataframe backend](https://docs.dask.org/en/stable/how-to/selecting-the-collection-backend.html) for Dask DataFrame. > [!IMPORTANT]
