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.

Title: Heterogeneity-Enriched Communication: Rethinking Data Movement for Data-Intensive AI
Modern AI workloads are increasingly data-intensive, and their scalability depends on how effectively computation and data movement are coordinated across heterogeneous systems. As datasets and model sizes continue to grow, the efficiency of data handling becomes increasingly important. This talk introduces Heterogeneity-Enriched Communication (HEC) as a new perspective for understanding and optimizing data movement in large-scale, data-driven AI. I will discuss how HEC principles inspire new opportunities in data compression and communication-efficient system designs that leverage modern CPUs, GPUs, DPUs, and emerging accelerators. Through recent studies and examples, I will illustrate how rethinking data movement alongside computation can improve the scalability and efficiency of distributed, data-intensive AI workloads and can provide a path toward the next generation of high-performance big data computing systems.
Speaker: Takaki Hatsui, RIKEN SPring-8 Center
Dr. Takaki Hatsui received his B.Eng. and M.Eng. degrees from Kyoto University in 1994 and 1996, and his Ph.D. from the Graduate University for Advanced Studies (SOKENDAI) in 1999. After postdoctoral research at the University of Tokyo and Uppsala University, he served as Assistant and later Associate Professor at the Institute for Molecular Science before joining RIKEN in 2007. He is currently leading the development of advanced X-ray imaging detectors and data infrastructure for the large-scale synchrotron and XFEL facilities, SPring-8 and SACLA, and concurrently serves as Project Leader for Semiconductor Applications at SPring-8.
Title: Towards an AI-Ready SPring-8: Key Prerequisites for Data-Intensive Photon Science
Next-generation synchrotron facilities, such as the upgraded SPring-8 (SPring-8-II) to be completed in 2029, will generate data volumes of up to an exabyte per year per instrument, driven by high-repetition, high–pixel-count imaging detectors, including the CITIUS detector developed through our collaboration. To fully exploit these capabilities, artificial intelligence must be integrated not as an add-on, but as a core component of the facility infrastructure. This keynote presents the key prerequisites for making SPring-8 AI-ready, focusing on the end-to-end data lifecycle in data-intensive photon science. Topics include scalable detector data acquisition, streaming data reduction, high-throughput data transport, and tight integration with high-performance computing and AI platforms.
