To be held on March 01- 04, 2027 in conjunction with SupercomputingAsia 2027, Singapore
Workshop Abstract
AI and data-intensive workloads are driving up both computational and energy demands, with data movement and storage now consuming energy on par with computation. Yet, these costs remain poorly understood and rarely optimized. This workshop brings together researchers and practitioners from AI, HPC, and energy domains to address the challenges of modeling, profiling, and optimizing data flows for performance and sustainability. Topics include power profiling, bottleneck analysis, and energy-aware strategies across diverse architectures, from high-end HPC to resource-constrained systems. The workshop emphasizes holistic energy optimization, highlighting data movement as a critical factor in application performance and sustainability. It encourages the development of methods and tools that improve energy efficiency and supports collaboration toward more sustainable computing practices.
Topics of Interest
This workshop will focus on key technical areas critical to energy-efficient data movement across modern computing systems, including:
Best practices for balancing throughput, latency, and sustainability
Metrics/measurement approaches for data movement energy efficiency
Performance modeling for data-intensive and AI workloads
Tools and methods for data movement, data flow profiling, and tuning
Characterization of emerging workload and the power profile
Energy-aware dataflow and I/O optimizations
Power monitoring and reduction strategies for underlying subsystems
Energy measurements and modeling in emerging hardware
Data movement in agentic workflows and agent-based systems
