Call for Papers

The 27th ACM Symposium on Operating Systems Principles seeks to present exciting, innovative research related to the design, implementation, analysis, evaluation, and deployment of computer systems software. SOSP takes a broad view of the systems area and solicits contributions from many fields of systems practice, including, but not limited to, operating systems, file and storage systems, distributed systems, cloud systems, mobile systems, secure systems, embedded systems, dependable systems, system management and virtualization. We also welcome work that explores the interface to related areas such as computer architecture, networking, programming languages, and databases. In keeping with SOSP tradition, we will favor work that explores new territory, continues a significant research dialogue, or reflects on experience with or measurements of state of the art implementations. Papers of particular merit will be forwarded to ACM Transactions on Computer Systems for possible publication.

Papers will be judged on novelty, significance, clarity, relevance, and correctness. A good paper will:

  • Consider a significant problem.
  • Propose and implement an interesting, compelling solution.
  • Demonstrate the practicality and benefits of the solution.
  • Draw appropriate conclusions.
  • Clearly describe what the authors have done.
  • Clearly articulate the advances beyond previous work.

We encourage submission of ground breaking work in significant new directions, with the understanding that evaluation criteria for papers addressing new problems may be different from those continuing a line of work in a more established area.

To facilitate broad technical discussion, all accepted papers will be made available online in advance of the conference.

Author Response Period

SOSP will provide an opportunity for authors to respond to reviews prior to final consideration of the papers at the program committee meeting. Authors must limit their responses to (a) correcting factual errors in the reviews or (b) directly addressing questions posed by reviewers. Responses should be limited to clarifying the submitted work. In particular, responses must not include new experiments or data, describe additional work completed since submission, or promise additional work to follow.

Submission of a response is optional. There is no explicit limit to the response, but authors are strongly encouraged to keep it under 500 words; reviewers are neither required nor expected to read excessively long rebuttals.

Submission Rules

This page describes the rules for submitted papers. Submissions violating these rules will not be considered for publication, and there will be no extensions for fixing violations. We encourage you to upload an early draft of the paper well before the deadline to check if the paper meets the formatting rules, and to check with the program chairs if you are uncertain about anonymity rules.


Submissions should contain original, unpublished material that is not under review at any other archival forum, including journals, conferences, and workshops with copyrighted proceedings. Submissions that extend authors' previous work are welcome, but authors must explain the differences between the SOSP submission and the prior work. Authors must also relate their SOSP submissions to relevant submissions of their own that are simultaneously under review for this or other venues. The next section describes how to relate your submission to your other work while maintaining anonymity.


SOSP will use double-blind reviewing. Please make a good faith attempt to anonymize your submission. Avoid identifying yourself or your institution explicitly or by implication (e.g., through the references or acknowledgments). The first page should use the paper ID assigned during registration in place of the author names.

Use care in referring to your own related work. Do not omit references to your prior work, as this would make it difficult for reviewers to place your submission in its proper context. Instead, reference your past work in the third person, just as you would any other piece of related work. For example, you might say "Our system modifies the the XYZ operating system built by Lee et al. [Lee17]".

In some cases, it is not credible to refer to your related work in the third person. For example, your submission may extend a previous workshop paper, or it may relate to a submission currently under review at SOSP or another venue. In these cases, you must still explain the differences between your SOSP submission and the other work, but you should cite the other work anonymously and e-mail the deanonymized work to the PC chairs.

If your submission reports on experiences with a system at your institution, you should refer to the system anonymously but describe the properties of the system that are needed to appreciate the work (e.g., size of the user base, volume of requests, etc.). We recognize that, in some cases, these properties may allow a reviewer to identify your institution.


Papers will be submitted electronically in PDF format via the web submission form.

Submissions may have at most 12 pages of technical content, including all text, figures, tables, appendices, etc. Bibliographic references are not included in the 12-page limit. Use A4 or US letter paper size, with all text and figures fitting inside a 178 x 229 mm (7 x 9 in) block centered on the page, using two columns separated by 8 mm (0.33) of whitespace. Use 10-point font (typeface Times Roman, Linux Libertine, etc.) on 12-point (single-spaced) leading. Graphs and figures should be readable when printed in grayscale, without magnification. All pages should be numbered and references within the paper should be hyperlinked.

Most of these rules are automatically applied when using the official SIGPLAN Latex or MS Word templates from the ACM.

For Latex, we recommend you use:



Reviewing will be done mostly by members of the program committee, with limited use of outside reviewers. Submissions will be treated as confidential; however, papers accompanied by nondisclosure agreement forms will not be considered for publication.

Papers selected by the program committee will be subject to revision and approval by a program committee member acting as a shepherd. Authors of accepted papers will be expected to supply electronic versions of their papers and encouraged to supply source code and raw data to help others replicate and understand their results. On acceptance, authors will be required to sign an ACM copyright release form. To facilitate technical discussions, all accepted papers will be posted online for pre-conference access.
