Objectives

In addition to traditional applications, the rise of AI and cloud computing has significantly increased the volume of data processing and communication required in high-performance computing (HPC).

Efficient data analytics and data movement across distributed and parallel environments (e.g., the Internet, inter-node networks, and system interconnects) have become critical factors in determining the performance and energy efficiency of supercomputers, data centers, and cloud platforms.

This workshop aims to address key research challenges related to big data from multiple perspectives, including data exploration, data compression, and big data systems.

To tackle these challenges, the workshop will aim to explore practical and effective approaches to data analytics and mining, big data visualization, data integration, scalable data compression, and storage/processing systems for big data.

These investigations will consider both the characteristics of large-scale data workloads and the constraints of modern hardware architectures.

In particular, the workshop will emphasize optimization strategies for big data processing, adaptive and general-purpose compression techniques, and high-performance systems designed for high-throughput, low-latency, and hardware-efficient data operations.
