Operating systems have evolved beyond traditional computers to power diverse environments, from edge devices and smart spaces to distributed clusters and cloud infrastructures. Despite their varying scales and applications, these systems share foundational principles: resource virtualization and function programmability. These same principles underpin software-defined paradigms (e.g., SDNs, SDS, and SDDCs), blurring the lines between traditional OS roles and emerging infrastructure abstractions. Future operating systems will unify these capabilities, acting as ubiquitous operating systems (UOSs), generalized platforms that manage hardware resources, provide programmable interfaces, and enable seamless integration across domains, from networks to datacenters to IoT ecosystems. The Workshop on Ubiquitous Operating System Research (WUOS) aims to catalyze discussions on the challenges and opportunities in designing next-generation UOSs.
All deadlines are at 11:59pm Anywhere on Earth (AOE).
