## Motivation and Objectives

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.

### Submission Guidelines

- All authors should submit manuscripts for review in a single-column format.
- Manuscripts must be at most 12 pages in PDF format including figures and references, formatted according to the ACM Proceedings Style.
- Authors submitting papers for DERAM2026 must do so via the EasyChair submission web page (https://easychair.org/conferences?conf=dream2026).
- The ACM templates for Word and LaTeX are shown below. Also, ACM has partnered with Overleaf and the ACM LaTeX template on Overleaf platform is available. Please follow STEP 1 (Microsoft Word/LaTeX) at “2. The Workflow and Templates” in https://www.acm.org/publications/authors/submissions. Please note that there are two different instructions for Word and LaTeX.
- The ACM templates for Word (https://www.acm.org/binaries/content/assets/publications/taps/acm_submission_template.docx) and LaTeX (https://portalparts.acm.org/hippo/latex_templates/acmart-primary.zip).
- For more details, please visit the Primary Article Templates page.
- We use single-blind reviewing process so you can keep authors' names, publications, etc.
