Abstract
--------------------------------
As the performance, power, and heat density of supercomputers continues to grow — driven by the integration of high-power heterogeneous components such as multi-core CPUs, GPUs, high-bandwidth memory, and high bandwidth interconnects — coordinated strategies across facilities, utilities, HPC systems, and applications are required to manage energy use, reduce environmental impact, and ensure long-term operational viability.

The Energy Efficient HPC State of the Practice workshop will focus on the operational, infrastructural, and environmental challenges of deploying and managing modern high-performance computing systems. The primary objective of this workshop is to capture and disseminate best practices, case studies, and reproducible operational experiences from HPC centers, facilities, and vendors worldwide.

While energy efficiency has long been recognized as a critical constraint, sustainability metrics such as greenhouse gas (GHG) emissions, embodied carbon, and water consumption are now also coming into focus. This workshop will explore how to address these challenges across the full lifecycle of HPC systems — from design and manufacturing through daily operations, reuse, and decommissioning.

This year’s workshop also broadens its lens to consider AI infrastructure, which increasingly mirrors HPC in system architecture and operational demands. There are lessons to be learned from the HPC community that should help with the operation of Megawatt-scale AI racks, warm-water cooling, and hyperscale deployments. The convergence of these domains presents an opportunity to align practices, metrics, and innovations in service of a shared future where performance and sustainability must coexist.

As part of this peer-reviewed workshop, we solicit papers that capture best practices, policies, procedures, and technologies. The vision is to help the broader community benefit from these experiences. The papers are intended to identify use cases, lessons learned, and best practices in design, commissioning, and operations. The solicited papers will be generally descriptive with concrete, reproducible, and empirical data gathered through surveys, case studies, and research for practice.

Workshop Topics
--------------------------------
Workshop Topics of interest include (but are not limited to) the following areas:
* Operational Data Analytics
* HPC performance for power, energy, carbon, and/or water
* Monitoring and control of power & energy
* Cooling technologies
* Mechanical and electrical system design
* Procurement considerations
* Sustainability modeling, measurement, monitoring, and management
* Energy-efficient computing across hardware, software, system architecture, and operations, including application-centric approaches
* Emerging challenges in HPC and AI workloads
* Digital twins

Paper Submission
--------------------------------
SCA/HPCAsia 2026 plans to provide an electronic proceedings publication for accepted workshop papers. In past years, SCA/HPCAsia workshop papers have been published in ACM-affiliated proceedings.

* Paper submission link: TBA
* Full paper (8 pages + 2 additional pages)
* Short paper (4 pages + 1 additional page)

Instructions for Authors and Participants
--------------------------------
* At least one author of each accepted workshop paper must complete the author registration.
* All participants (including invited speakers) must complete the registration and pay registration fee for SCA/HPCAsia 2026. Further instruction will be available at https://www.sca-hpcasia2026.jp.
