NVIDIA cuDF

NVIDIA cuDF (pronounced "KOO-dee-eff") is an open-source, GPU-accelerated DataFrame library for structured/tabular data processing, Apache 2.0 licensed and built on the Apache Arrow columnar format, pushing core operations like joins, aggregations, sorting, and groupbys onto GPU cores, often with no code changes since unsupported operations fall back to CPU automatically. Internally it's composed of libcudf (the core CUDA C++ engine), pylibcudf (Cython bindings), the cudf Python package (a pandas-mirroring API plus the zero-code-change cudf.pandas accelerator), cudf-polars (a GPU engine for Polars), and dask-cudf (a Dask backend for scaling across multiple GPUs/nodes). It's one library within NVIDIA's broader RAPIDS/CUDA-X Data Science suite.
