Abstract

Apache Spark is an in-memory data processing system that
supports both SQL queries and advanced analytics over large
data sets. In this paper, we present our design and implementation
of Spark-GPU that enables Spark to utilize GPU’s massively
parallel processing ability to achieve both high performance and
high throughput. Spark-GPU transforms a general-purpose data
processing system into a GPU-supported system by addressing
several real-world technical challenges including minimizing
internal and external data transfers, preparing a suitable data
format and a batching mode for efficient GPU execution, and
determining the suitability of workloads for GPU with a task
scheduling capability between CPU and GPU. We have comprehensively
evaluated Spark-GPU with a set of representative
analytical workloads to show its effectiveness. Our results show
that Spark-GPU improves the performance of machine learning
workloads by up to 16.13x and the performance of SQL queries
by up to 4.83x.
