Objective
----------------------------------
The EESP workshop fosters the exchange of innovative strategies, tools, and best practices to enhance energy efficiency across modern computing environments. With rising energy costs, increasing CO2 emissions, and growing pressure on power infrastructure, optimizing energy use is now critical for sustainable computing. The workshop explores how to balance performance, power, and sustainability, providing participants with a guidebook of actionable strategies for exascale, Tier-1, and Tier-2 centers. Through greener, cost-effective, energy-efficient practices, including system–application co-design, attendees gain a competitive edge in advancing sustainability. Aligned with the Sustainable Development Goals, EESP promotes collaboration between HPC and AI communities to support environmentally responsible innovation. It offers guidance for system operators and facility managers on reducing Power Usage Effectiveness (PUE) and sourcing green energy, while helping users design energy-conscious experiments. EESP also addresses full-lifecycle sustainability, from system design and operation to reuse and decommissioning, and examines how HPC strategies can support energy-efficient AI infrastructure amid growing convergence. While current tenders often emphasize raw hardware metrics, the workshop highlights sustained (application) performance, rather than peak performance, as the key measure of long-term success.

Scope
----------------------------------
EESP invites academia, supercomputing centers, industry, national laboratories, and policymakers to collaborate on advancing energy-efficient practices. To achieve end-to-end visibility and adaptability in energy usage, EESP emphasizes cross-layer innovation, encompassing advances in hardware, software, runtime systems and system-application co-design. This includes data-driven analytics and monitoring, energy-efficient methodologies, operational case studies, benchmarking frameworks, AI–HPC convergence, and sustainability metrics that extend beyond energy efficiency, such as carbon emissions. The workshop fosters dialogue between Tier-0/1 and Tier-2 centers to help adapt Tier-0/1 innovations for more constrained budgets. While investment priorities differ across tiers, challenges in software and applications remain universal, serving as a unifying link. It targets financial and technical solutions applicable to HPC clusters, data centers, and cloud infrastructures worldwide.

Topics of Interest
----------------------------------
The workshop aims to benefit the broader community by sharing use cases, lessons learned, and best practices through descriptive papers. We solicit papers which encompass the following topics of interest but are not limited to:
* Energy-aware software and application optimization
* Programming models, compilers, and tools for energy-efficient computing
* Energy-efficient hardware architectures and design practices
* Energy-aware resource management, and power-steering runtimes
* Operating system and network techniques for power and thermal control
* Tools/frameworks for energy monitoring, instrumentation and analysis
* Processor and system energy models including behavioral insights
* Cluster-wide energy benchmarking and regression analysis
* Comparative benchmarking of node architectures and memory systems
* Analysis of long-term energy degradation in CPUs and GPUs
* Sustainable HPC through mixed precision algorithms
* Renewable energy sources for HPC systems
* Energy-efficient procurement frameworks and lifecycle cost analysis
* Operational analytics and control for real-time power adaptation
* Integration, energy/performance profiling and optimization of AI workloads
* Emerging trends and challenges in HPC/AI energy consumption

Paper Format and Submission
----------------------------------
Papers should be either short (work-in-progress, 4 two-column pages) or regular (8 two-column pages); references, appendices, and reproducibility artifacts are excluded from the page limit. Authors can submit one extra page for short papers or two extra pages for regular papers after the review to address reviewer feedback. Submitted papers must be original and not previously published or under review elsewhere. Content generated by AI tools must be clearly and thoroughly described, and AI systems cannot be credited as authors. Authors may optionally submit an artifact description and artifact evaluation (AD/AE) appendix detailing their software environments and computational experiments to enable independent replication. The AD/AE appendix is not reviewed but will be included after acceptance in accordance with SC guidelines. Each submission will undergo a minimum of three double-blind peer reviews; authors must remove all identifying information from the manuscript. Papers must be submitted online via the SC Linklings system in PDF format, using the IEEE template.

EESP Paper Proceedings
----------------------------------
Papers accepted and presented at EESP 2026 will be published as part of the SC workshop proceedings in the IEEE Xplore Digital Library.

EESP Best Paper Award
----------------------------------
The workshop program and organizing committee will select one paper for the Best Paper Award. The selection will be based on the established review criteria: originality, technical soundness, potential impact, significance, and quality of presentation. The Best Paper Award certificate will be presented in person during the workshop.

EESP Journal Special Issue
----------------------------------
The authors of the highest-quality accepted EESP papers, as selected by the Program and Organizing Committee of the workshop, will be invited to submit extended versions of their work to a special issue of the International Journal of High Performance Computing Applications.

We look forward to your contributions and participation in the EESP workshop in Chicago in November 2026!
