### Scope:
PPoPP is the premier forum for leading work on all aspects of parallel
and performance programming, including theoretical foundations,
techniques, languages, compilers, runtime systems, tools,
applications, and practical experience. This symposium focuses on
improving the programming productivity and performance engineering of
all concurrent and parallel systems - multicore, multi-threaded,
heterogeneous, clustered, and distributed systems, grids, accelerators
such as ASICs, GPUs, FPGAs, data centers, clouds, large scale
machines, and quantum computers. PPoPP is also interested in new and
emerging parallel workloads and applications, such as artificial
intelligence and large-scale scientific/enterprise workloads.
Specific topics of interest include (but are not limited to):
* Languages, compilers, and runtime systems for parallel programs
* Parallel programming frameworks and domain-specific languages
* Parallel programming for emerging hardware, including AI
accelerators, processor-in-memory, programmable logic, and
non-volatile memory technologies
* High-performance libraries
* Parallel programming for deep memory hierarchies including nonvolatile memory
* Parallel algorithms
* Parallel applications including scientific computing and enterprise workloads
* Artificial intelligence and machine learning for parallel systems,
including their use in system design, optimization, and runtime
decisions
* Development, analysis, or management tools
* Performance analysis, debugging and optimization
* Productivity tools for parallel systems
* Software engineering for parallel programs
* Parallel programming theory and models
* Formal analysis and verification
* Concurrent data structures
* Synchronization and concurrency control
* Fault tolerance for parallel systems
* Middleware for parallel systems
Papers should report on original research relevant to parallel
programming and should contain enough background materials to make
them accessible to the entire parallel programming research community.
Papers describing experience should indicate how they illustrate
general principles or lead to new insights; papers about parallel
programming foundations should indicate how they relate to practice.
PPoPP submissions will be evaluated based on their technical merit and
accessibility. Submissions should clearly motivate the importance of
the problem being addressed, compare to the existing body of work on
the topic, and explicitly and precisely state the paper's key
contributions and results towards addressing the problem. Submissions
should strive to be accessible both to a broad audience and to experts
in the area.
### Paper Submission:
* Conference submission site: https://ppopp26.hotcrp.com
All submissions must be made electronically through the conference
website and include an abstract (100–400 words), author contact
information, the full list of authors and their affiliations. Full
paper submissions must be in PDF format printable on both A4 and US
letter-size paper.
All papers must be prepared in two-column ACM Conference Format,
specifically the acmart document class (available here:
https://www.sigplan.org/Resources/Author/) with the sigplan option and
10-point font size. We recommend preparing your submission in Latex
starting with the following template:
https://ppopp26.sigplan.org/getImage/orig/ppopp-acmart-sigplanproc-template.tex.
This template ensures that there are no line numbers and headers in
the margins to avoid triggering HotCRP’s format checker. Refrain from
squeezing additional space by tweaking the template above, e.g., by
manipulating vertical space, reducing margins, line spacing, heading
space, column separation, etc. Ensure that caption fonts are at least
9 pt and all fonts in figures and tables are at least 8 pt. Program
chairs will inspect submissions using format checking tools and
reserve the right to reject submissions that violate the formatting
rules. If you would like to use Word or other Latex template, please
ensure that your submission follows all the formatting guidelines. You
may want to consult the official ACM information on the Master Article
Template and related tools.
Papers should contain a maximum of 10 pages of text and figures, but
NOT INCLUDING references. There is no page limit for references, and
they must include the names of all authors (not et al.) and spell out
the publication year and venue (and not simply point to the doi link).
Appendices are not allowed, but the authors may submit supplementary
material, such as proofs or source code; all supplementary material
must be in PDF or ZIP format. Looking at supplementary material is at
the discretion of the reviewers.
Submission is double-blind, and authors will need to identify any
potential conflicts of interest with PC and Extended Review Committee
members, as defined here:
http://www.sigplan.org/Resources/Policies/Review/ (ACM SIGPLAN
policy).
PPoPP 2026 will employ a double-blind reviewing process. To facilitate
this process, submissions should not reveal the identity of the
authors in any way. Authors should leave out author names and
affiliations from the body of their submission. They should also
ensure that any references to authors' own related work should be in
the third person (e.g., not "We build on our previous work ..." but
rather "We build on the work of ..."). The purpose of this process is
to help the PC and external reviewers come to an initial judgment
about the paper without bias, not to make it impossible for them to
discover the authors if they were to try. Nothing should be done in
the name of anonymity that weakens the submission or makes the job of
reviewing the paper more difficult. In particular, important
background references should not be omitted or anonymized. In
addition, authors should feel free to disseminate their ideas or draft
versions of their papers as they normally would. For instance, authors
may post drafts of their papers on the web or give talks on their
research ideas. Authors with further questions on double-blind
reviewing are encouraged to contact the Program Chairs by email.
To facilitate fair and unbiased reviews for all submissions, PPoPP
2026 may utilize the Toronto Paper Matching System (TPMS) to assign
papers to reviewers. From the authors' perspective, this decision
means that the submissions may be uploaded to TPMS.
Submissions should be in PDF and printable on both US Letter and A4
paper. Papers may be resubmitted to the submission site multiple times
up until the deadline, but the last version submitted before the
deadline will be the version reviewed. Papers that exceed the length
requirement, which deviate from the expected format, or that are
submitted late will be rejected.
All submissions that are not accepted for regular presentations will
be automatically considered for posters. Two-page summaries of
accepted posters will be included in the conference proceedings.
To allow reproducibility, we encourage authors of accepted papers to
submit their papers for Artifact Evaluation (AE). The AE process
begins after the acceptance notification and is run by a separate
committee whose task is to assess how the artifacts support the work
described in the papers. Artifact evaluation is voluntary and will not
affect paper acceptance but will be taken into consideration when
selecting papers for awards. Papers that go through the AE process
successfully will receive at least one ACM reproducibility badge,
printed on the published version. More information will be posted on
the AE website.
Deadlines expire at midnight anywhere on Earth.
### Publication Date:
The titles of all accepted papers are typically announced shortly
after the author notification date (late November 2025). Note,
however, that this is not the official publication date. The official
publication date is the date the proceedings are made available in the
ACM Digital Library. ACM will make the proceedings available via the
Digital Library, up to 2 weeks prior to the first day of the
conference. The official publication date affects the deadline for any
patent filings related to published work.
### ACM Publications Policies:
By submitting your article to an ACM Publication, you are hereby
acknowledging that you and your co-authors are subject to all ACM
Publications Policies, including ACM's new Publications Policy on
Research Involving Human Participants and Subjects. Alleged violations
of this policy or any ACM Publications Policy will be investigated by
ACM and may result in a full retraction of your paper, in addition to
other potential penalties, as per ACM Publications Policy
https://www.acm.org/publications/policies/research-involving-human-participants-and-subjects
Starting from January 2026, *all ACM publications become Open Access*.
See https://www.acm.org/publications/openaccess for details. Authors
must be aware that the Article Processing Charges listed in the page
applies to all accepted papers.
Please ensure that you and your co-authors obtain an ORCID ID, so you
can complete the publishing process for your accepted paper. We are
committed to improving author discoverability, ensuring proper
attribution and contributing to ongoing community efforts around name
normalization; your ORCID ID will help in these efforts. Please follow
the https://dl.acm.org/journal/pacmcgit/author-guidelines link to see
