Authors are invited to submit original and innovative papers to the Refereed Papers Track of the 2018 USENIX Annual Technical Conference. We seek high-quality submissions that further the knowledge and understanding of modern computing systems with an emphasis on implementations and experimental results. We encourage papers that break new ground, present insightful results based on practical experience with computer systems, or are important, independent reproductions/refutations of the experimental results of prior work. USENIX ATC '18 has a broad scope, and specific areas of interest include (but are not limited to): -Architectural interaction -Big data infrastructure -Cloud and edge computing -Distributed and parallel systems -Embedded systems -Energy/power management -File and storage systems -Internet of Things -Machine learning and systems interactions -Mobile and wireless -Networking (WAN, LAN, and datacenter) and network services -Operating systems -Reliability, availability, and scalability -Security, privacy, and trust -System and network management and troubleshooting -Usage studies and workload characterization -Virtualization
