The 18th Workshop on Hot Topics in Operating Systems

31 May–2 June 2021, Cyberspace, People’s Couches, and Most Likely Zoom


Continuing the HotOS tradition, participants in the 18th Workshop on Hot Topics in Operating Systems will present and discuss new ideas in systems research and how technological advances and new applications are shaping our computational infrastructure. We welcome researchers and practitioners old and new.

Call for papers and discussions

What’s changed? HotOS 2021 will feature blind submission, and in addition to 5-page position and research papers, we request one-page proposals for panels and events.

The 18th Workshop on Hot Topics in Operating Systems hopes to bring together researchers and practitioners in computer systems to engage in a lively discussion on the principles and practices of building systems software. Continuing the HotOS tradition, participants will present new ideas and debate future research agendas in systems research.

We solicit position papers that propose new directions of systems research, advocate innovative approaches to long-standing problems, or report on deep insights gained from experience with real-world systems. We seek early-stage work where the authors can benefit from community feedback. An ideal submission has the potential to open a line of inquiry that results in multiple conference papers by different authors in related venues, rather than a single follow-on conference paper. The program committee will explicitly favor papers likely to stimulate reflection and discussion.

HotOS takes a broad view of systems research. This includes operating systems, storage, distributed systems, mobile and embedded systems, virtualization, programming languages, networking, security, dependability, and manageability, as well as new systems contributions influenced by other fields such as hardware design, machine learning, verification, economics, social organization, and biological or other nontraditional computing systems.

Research and position paper submissions must be no longer than 5 pages including figures and tables, plus as many pages as needed for references. Text should be formatted in two columns on 8.5x11-inch paper using 10-point Times-Roman font on 12-point (single-spaced) leading, 1-inch margins, and a 0.25-inch gutter (separation between the columns). Submissions will be double blind. The title and an abstract should appear on the first page; authors should not. Authors must make a good faith effort to anonymize their submissions, and they should not identify themselves either explicitly or by implication (e.g., through the references or acknowledgments). Pages should be numbered. Figures and tables should not require magnification for viewing; they may contain color, but should be legible when printed or displayed in black and white. Submissions not meeting these criteria will be rejected without review, and no deadline extensions will be granted for reformatting. Here is a style file and a Latex template that you can use

HotOS XVIII will also feature panels and events with the aim of inspiring lively discussion and research direction-setting independent of any specific work. Panels and events may have many formats, from conventional panel discussions to breakouts to games. If you are interested in hosting or proposing an event, please submit a 1-page proposal (using the same format above) describing topic, format, and length (up to 90 minutes), plus as many pages as necessary for references and supporting letters from planned participants. Proposals will be evaluated based on relevance of topic and potential to engage the audience. We especially encourage panel topics including but not limited to: industry perspectives on systems research; diversity and inclusion in systems research; under-appreciated open source technologies; and hardware trends and their implications for the future of systems research.

Research and position papers as well as panel proposals must be received by the Wednesday 3 February, 2021, AoE. Panel submissions do not need to be anonymous (e.g., panel submissions can be single blind). This is a hard deadline. Papers and proposals should be submitted as PDF files via the web submission form. Please select your submission type on the form (paper or proposal).

Revised versions of all accepted papers will be available online to registered attendees before the workshop. After the workshop, accepted papers will be made available on the workshop site, along with slides of the presentation and in some cases a summary of the discussion.

Simultaneous submission of the same work to multiple venues, submission of previously published work, or plagiarism constitutes dishonesty or fraud. ACM, like other scientific and technical conferences and journals, prohibits these practices and may take action against authors who have committed them. See the ACM plagiarism policy and procedures for details.

See the HotOS code of conduct and diversity and inclusion guidelines.
