RAPIDS APIs

cuDF

cuDF is a Python GPU DataFrame library (built on the Apache Arrow columnar memory format) for loading, joining, aggregating, filtering, and otherwise manipulating data.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

dask-cuDF

Dask-cuDF extends Dask where necessary to allow its DataFrame partitions to be processed using cuDF GPU DataFrames instead of Pandas DataFrames. Dask-cuDF is used to leverage multiple gpus and multiple nodes for more performance at larger scales

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cuML

cuML is a suite of libraries that implement machine learning algorithms and mathematical primitives functions that share compatible APIs with other RAPIDS projects.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cuGraph

cuGraph is a GPU accelerated graph analytics library, with functionality like NetworkX, which is seamlessly integrated into the RAPIDS data science platform. cuGraph supports GNNs with PyG, DGL packages and cugraph-ops (for low level optimized operations) as well as cugraph-service for analytics on a remote graph and WHOLEGRAPH for memory management.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cuxfilter

cuxfilter acts as a connector library, which provides the connections between different visualization libraries and a GPU dataframe without much hassle. This also allows the user to use charts from different libraries in a single dashboard, while also providing the interaction.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cuSpatial

cuSpatial is a GPU-accelerated vector GIS library including binary predicates (DE-9IM), point-in-polygon, spatial join, distances, and trajectory analysis.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cuProj

cuProj is a GPU-accelerated geographic and geodetic coordinate transformation library which supports projecting coordinates between coordinate reference systems (CRSes), compatible with PyProj.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cusignal

cuSignal functionality has been moved to CuPy. Please see the CuPy documentation for more information.

DOCS

Java + cuDF

Java bindings for the cuDF library.

DOCS stable (24.12) | legacy (24.10)

cuCIM

The RAPIDS cuCIM is an extensible toolkit designed to provide GPU accelerated I/O, computer vision & image processing primitives for N-Dimensional images with a focus on biomedical imaging.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

cuVS

cuVS is a library for GPU-accelerated vector search and clustering.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

KvikIO

KvikIO is a Python and C++ library for high performance file IO using GPUDirect Storage (GDS).

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

RAFT

RAFT contains fundamental widely-used algorithms and primitives for vector search, machine learning, and information retrieval.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

Dask-CUDA

Various utilities to improve deployment and management of Dask workers on CUDA-enabled systems.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

RMM

RAPIDS Memory Manager (RMM) is a central place for all device memory allocations in cuDF (C++ and Python) and other RAPIDS libraries. In addition, it is a replacement allocator for CUDA Device Memory (and CUDA Managed Memory) and a pool allocator to make CUDA device memory allocation / deallocation faster and asynchronous.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

RAPIDS Libraries

libcudf

libcudf is a C/C++ CUDA library for implementing standard dataframe operations.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

libcuspatial

libcuspatial is a GPU-accelerated header-only C++ vector GIS library including binary predicates (DE-9IM), point-in-polygon, spatial join, distances, and trajectory analysis.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

libcuproj

libcuproj is a C++ header-only library for GPU-accelerated geographic and geodetic coordinate transformation library which supports projecting coordinates between coordinate reference systems (CRSes), similar to PROJ.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)

libcuml

libcuml is a C/C++ CUDA library for cuML.

DOCS stable (24.12) | nightly (25.02) | legacy (24.10)
