Conducting In-Depth Data Analysis and Interpretation
In the realm of data analysis, Graphics Processing Units (GPUs) are no longer confined to deep learning training. They are rapidly becoming indispensable for performing entire Exploratory Data Analysis (EDA) workflows, including data processing, vector search, clustering, and graph analytics.
Recently, a system equipped with an Intel 4 core i5-7600K 7th Generation Kaby Lake processor and a Quadro P2000 GPU was put to the test. The GPU, boasting 5 GB GDDR5 and 1024 Cuda Cores, demonstrated its prowess when a large 1.1GB text file was read and transferred in just about 2 seconds.
Libraries like NVIDIA cuDF provide GPU-accelerated DataFrame operations that are API-compatible with pandas, Polars, and Apache Spark. This means that analysts can enjoy GPU speedups for typical data wrangling and analysis tasks without having to rewrite their code. cuDF supports efficient memory usage, handles larger-than-GPU-memory datasets transparently, and integrates with Python data science tools for end-to-end GPU workflows.
NVIDIA's cuVS offers GPU-accelerated vector search and clustering capabilities, accelerating indexing and clustering steps critical to high-dimensional data exploration. For graph analytics, NVIDIA cuGraph provides significant speedups for NetworkX workloads, enabling scalable exploration of complex networks.
The benefits of using GPUs in EDA are evident. They allow analysts to work faster on larger and more complex datasets, improving data wrangling, clustering, similarity searches, and graph computations. While GPUs remain essential for deep learning training, their role in accelerating the entire data analysis and exploration pipeline is maturing and expanding, supported by a growing open-source ecosystem optimized for GPU workflows.
The system under test, running on Ubuntu 22.04.1 LTS, also featured a Corsair Integrator 500w power supply, a Z270N-WIFI motherboard, and 32.0 Gig of Corsair VENGEANCE Red memory. The system's storage supports SSD, FDD, and mSata drives.
A 7M record dataset, the 7+ Million Company Dataset, was chosen for the GPU experiment. Aggregation and groupby operations were extremely fast on the GPU, and the syntax was the same as Pandas. Loading the data frame into RAM using Pandas took 16 seconds, which is almost eight times slower than on the GPU.
The benchmark using cudf.DataFrame.from_pandas! worked out of the box without any 'SUDOing' or dependency issues. However, it's worth noting that the GPU devices do not behave like the conventional approach, and tools like %%timeit%% can cause memory errors on the GPU.
In summary, GPUs are not just limited to deep learning training; they are highly useful and increasingly common for performing comprehensive EDA tasks from data manipulation through advanced analytics. The dataset used in the experiment, licensed under the creative commons CC0.01, is available for further exploration and research.
