To be held on January 26, 2026 in conjunction with SupercomputingAsia 2026 and the International Conference on High Performance Computing in Asia-Pacific Region 2026, Osaka, Japan
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.
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 and 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

Michela Taufer is an ACM Distinguished Scientist. She was a J.P. Morgan Chase Scholar at the University of Delaware where she led the Global Computing Lab to promote the use of high performance computing to advance sciences. Michela Taufer joined the University of Delaware in 2007 where she was promoted to associate professor with tenure in 2012 and full professor in 2017. She earned her MS in computer engineering from the University of Padova and her PhD in computer science from the Swiss Federal Institute of Technology (ETH). She was a post-doctoral research supported by the La Jolla Interfaces in Science Training Program (also called LJIS) at UC San Diego and The Scripps Research Institute. Before she joined the University of Delaware, Taufer was faculty in computer science at the University of Texas at El Paso.
Taufer has a long history of interdisciplinary work with high-profile computational biophysics groups in several research and academic institutions. Her research interests include software applications and their advance programmability in heterogeneous computing (i.e., multi-core platforms and GPUs); cloud computing and volunteer computing; and performance analysis, modeling and optimization of multi-scale applications. She has been serving as the principal investigator of several NSF collaborative projects. She also has significant experience in mentoring a diverse population of students on interdisciplinary research. Her training expertise includes efforts to spread high-performance computing participation in undergraduate education and research as well as efforts to increase the interest and participation of diverse populations in interdisciplinary studies.
Taufer has served on numerous IEEE program committees (SC and IPDPS among others) and has reviewed for most of the leading journals in parallel computing. She served as the IEEE Cluster 2015 General co-Chair and the IEEE IPDPS 2017 General Chair. She is the ACM/IEEE SC19 General Chair.
