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

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.
