Sustainable Supercomputing Workshop
at SC25 St. Louis, Nov 16th-21st
Welcome to the SC25 sustainable computing workshop which will gather users, researchers, hardware, and software developers to address opportunities and challenges of sustainability in the supercomputing context.
Paper Submission Deadline: extended to 14th August 2025
Author Notification: 12th September 2025
Camera Ready Paper Deadline: 29th September 2025
Improving the sustainability of supercomputing provides many opportunities when the end-to-end cycle is considered. From the design of computational circuits and systems; to the power and cooling that is used to operate them, along with the suite of software tools used to administrate, maintain, and raise operational efficiency of HPC systems. All elements of the system must be considered, from compute nodes and interconnects, to IO and storage components of the system.
Important Information
We solicit papers on all topics related to sustainable supercomputing, from data centres to hardware, and for system software to applications. Topics of interest include, but are not limited to the following:
Energy efficient hardware for HPC & AI (design, performance, usability)
Embodied carbon, system lifecycle and circular economy studies
Sustainable data centre operation and design
System software for managing and optimising power/energy and utilisation/throughput
Power monitoring, system and data centre telemetry
Whole system workload energy/power efficiency analysis and optimisation
Application-level efficiency analysis and optimisation
