This half day workshop will convene a diverse group of experts in operating system and runtime research with the goals of enabling the socialization of early works and ideas, building connections between OS/runtime researchers and the broader SC community, and highlighting current relevant research to facilitate early feedback.

Note: Accepted papers will appear in the SC26 workshop proceedings

 News & Announcements

• [3/18/2026] - The ROSS Workshop has been accepted as a half-day workshop to be included as part of the SC26 program!  

 Workshop Scope

The ROSS is a workshop aimed at identifying looming problems and discussing promising research solutions in the area of runtime and operating systems for extreme-scale supercomputer systems. Specifically, ROSS focuses on principles and techniques to design, implement, optimize, or operate runtime and operating systems for extreme-scale supercomputing and cloud environments.  In addition to typical workshop publications, we encourage novel and possibly immature ideas, provided that they are interesting and on-topic.  Well argued position papers are also welcome.

This workshop will consider all aspects of OS and runtime systems at extreme-scale including, but not limited to:

• OS and runtime system scalability on many-node and multi/many-core systems;

• Management of heterogeneous and reconfigurable compute resources, including FPGAs, GPUs, etc;

• Management of emerging post-moore computing architectures, including quantum, neuromorphic, etc;

• Distributed/hybrid/partitioned OSs and runtime systems for supercomputing;

• Analysis and prevention of system noise and performance variability;

• Runtime and operating systems for resource disaggregation;

• Modeling and performance analysis of runtime systems;

• The use of machine learning and AI techniques in the autotuning of system software and resource management;

• OS and runtime considerations for large-volume, high-performance I/O;

• Memory management and emerging memory technologies;

• OS and runtime aspects of HPC in the cloud, convergence of supercomputing and cloud environments;

• Infrastructure for cloud functions and serverless computing in the context of HPC;

• OS and runtime support for emerging workloads such as on-demand or persistent service use cases;

• Virtualization in HPC, including virtual machines and application containers;

• The role of the OS and runtime system in minimizing power usage and energy efficiency;

• OS and runtime impacts of security and trust for HPC.
