Overview

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

cuDF 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.

For example, the following snippet downloads a CSV, then uses the GPU to parse it into rows and columns and run calculations:

import cudf, requests
from io import StringIO

url = "https://github.com/plotly/datasets/raw/master/tips.csv"
content = requests.get(url).content.decode('utf-8')

tips_df = cudf.read_csv(StringIO(content))
tips_df['tip_percentage'] = tips_df['tip'] / tips_df['total_bill'] * 100

# display average tip by dining party size
print(tips_df.groupby('size').tip_percentage.mean())

Output:

size
1    21.729201548727808
2    16.571919173482897
3    15.215685473711837
4    14.594900639351332
5    14.149548965142023
6    15.622920072028379
Name: tip_percentage, dtype: float64

Quick Start

Please see the Demo Docker Repository, choosing a tag based on the NVIDIA CUDA version you're running. This provides a ready to run Docker container with example notebooks and data, showcasing how you can utilize cuDF.

Installation

CUDA/GPU requirements

CUDA 11.2+
NVIDIA driver 450.80.02+
Pascal architecture or better (Compute Capability >=6.0)

Conda

cuDF can be installed with conda (miniconda, or the full Anaconda distribution) from the rapidsai channel:

conda install -c rapidsai -c conda-forge -c nvidia \
    cudf=23.02 python=3.10 cudatoolkit=11.8

We also provide nightly Conda packages built from the HEAD of our latest development branch.

Note: cuDF is supported only on Linux, and with Python versions 3.8 and later.

See the Get RAPIDS version picker for more OS and version info.

Open GPU Data Science

The RAPIDS suite of open source software libraries aim to enable execution of end-to-end data science and analytics pipelines entirely on GPUs. It relies on NVIDIA® CUDA® primitives for low-level compute optimization, but exposing that GPU parallelism and high-bandwidth memory speed through user-friendly Python interfaces.

Apache Arrow on GPU

The GPU version of Apache Arrow is a common API that enables efficient interchange of tabular data between processes running on the GPU. End-to-end computation on the GPU avoids unnecessary copying and converting of data off the GPU, reducing compute time and cost for high-performance analytics common in artificial intelligence workloads. As the name implies, cuDF uses the Apache Arrow columnar data format on the GPU. Currently, a subset of the features in Apache Arrow are supported.
