PPoPP is the premier forum for leading work on all aspects of parallel
programming, including theoretical foundations, techniques, languages,
compilers, runtime systems, tools, and practical experience. In the context
of the symposium, “parallel programming” encompasses work on
concurrent and parallel systems (multicore, multi-threaded, heterogeneous,
clustered, and distributed systems; grids; data centers; clouds; and large
scale machines). Given the rise of parallel architectures in the consumer
market (desktops, laptops, and mobile devices) and data centers, PPoPP
is particularly interested in work that addresses new parallel workloads
and issues that arise out of extreme-scale applications or cloud platforms,
as well as techniques and tools that improve the productivity of parallel
programming or work towards improved synergy with such emerging

Specific topics of interest include (but are not limited to): - Compilers and
runtime systems for parallel and heterogeneous systems - Concurrent data
structures - Development, analysis, or management tools - Fault tolerance
for parallel systems - Formal analysis and verification -
High-performance / scientific computing - Libraries - Middleware for parallel
systems - Parallel algorithms - Parallel applications and frameworks -
Parallel programming for deep memory hierarchies including nonvolatile memory -
Parallel programming languages - Parallel programming theory and models -
Parallelism in non-scientific workloads: web, search, analytics, cloud,
machine learning - Performance analysis, debugging and optimization -
Programming tools for parallel and heterogeneous systems - Software engineering
for parallel programs - Software for heterogeneous architectures - Software
productivity for parallel programming - Synchronization and concurrency control

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.
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. Authors of papers that do not pass the first round of
reviewing will receive a notification so that they can start working as early as
possible on revising their papers and resubmitting them to other conferences
or journals.

Paper Submission:

Conference submission site:

All submissions must be made electronically through the conference web site
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
formatted printable on both A4 and US letter size paper.

All papers must be prepared in ACM Conference Format using the 2-column
acmart format: use the SIGPLAN proceedings template
acmart-sigplanproc-template.tex for Latex,and interim-layout.docx for Word.
You may also want to consult the official ACM information on the Master Article
Template and related tools. Important note: The Word template (interim-layout.docx)
on the ACM website uses 9pt font; you need to increase it to 10pt.

Papers should contain a maximum of 10 pages of text (in a typeface no smaller
than 10 point) or figures, NOT INCLUDING references. There is no page limit
for references and they must include the name of all authors (not {et al.}).
Appendices are not allowed, but the authors may submit supplementary material,
such as proofs or source code; all supplementary material must be in PDF 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: (ACM SIGPLAN policy).

PPoPP 2021 will employ a lightweight 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 and from the supplementary material. 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 paper 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 Chair by email.

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, that 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 one or several of the ACM reproducibility badges, printed on the
papers themselves. More information will be posted on AE website.

Deadlines expire at midnight anywhere on earth.
