================================
Scope, Aims, and Topics
================================
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

================================
Submission Guidelines
================================
Submissions must be in English and formatted according to the ACM Proceedings Style. 

The page limits (short or regular papers) and submission link will be announced later.

We use single-blind reviewing process so you can keep authors' names, publications, etc. Each paper will get at least three reviews from the committee members.

The submitted papers must be original work that have not previously been published or under consideration for publication in any other conference or journal

Submission Link: TBA
