The 14th Workshop on Hot Topics in Operating Systems will bring together practitioners and researchers in computing systems, broadly construed. Continuing the HotOS tradition, participants will present and discuss new ideas about computer systems research and how technological advances and new applications are shaping our computational infrastructure. Computing systems are expanding beyond the traditional roles on the smartphone, desktop, and datacenter: they now encompass a broad swath of new technologies, ranging from body-implantable embedded devices to massive-scale stream processing systems spanning multiple continents. At the same time, the deluge of personal, corporate, sensitive, ephemeral, or historical information flowing over all technological facets of modern computing poses significant systems challenges. Systems for the next decade will have to keep such information private, authentic, continuously analyzed, durable, and available, and must do so not only better and faster, but also more reliably and while consuming less energy. We solicit position papers that propose new directions of research, advocate innovative approaches, report on noteworthy actual experience in an emerging area, or generate lively discussion around an important topic. HotOS takes a broad view of systems, including operating systems, storage, networking, languages and language engineering, security, fault tolerance, and manageability. We are also interested in systems contributions influenced by other fields such as hardware design, machine learning, control theory, networking, economics, social organization, and biological or other nontraditional computing systems. To ensure a vigorous workshop environment, attendance is limited. Participants will be invited based on their submissions' originality, technical merit, topical relevance, and likelihood of leading to insightful technical discussions that will influence future systems research. Submissions may not be under concurrent consideration for any other venue. To promote discussion, the review process will heavily favor submissions that are forward-looking and open-ended, as opposed to those that summarize more mature work on the verge of conference publication. In general, at most two authors per accepted paper will be invited to the workshop.
