This is a CALL FOR PAPERS for


13th International Workshop on Polyhedral Compilation Techniques: impact-workshop.org

held in conjunction with HiPEAC 2023 in Toulouse, France.

Important Dates

Submission: November 24, 2022 (AoE)
Author notification: December 19, 2022
Final version due: January 12, 2023 (AoE)
Workshop: January 16, 2023

For this edition we accept two kinds of submissions: paper submissions and presentation-only submissions.


Polyhedral compilation techniques receive more attention than ever from both researchers and practitioners. Thanks to a unified formalism for parallelization and memory optimization, polyhedral techniques play a central role in a wide range of domain-specific languages and optimizing compilers, with high impact in competitive areas such as machine learning, scientific computing and media processing.

IMPACT is a unique event focusing on polyhedral compilation. The workshop brings together researchers and practitioners for a high-quality one-day event including a keynote, paper presentations, and work-in-progress discussions. The workshop has a well established tradition of high quality, extensive peer reviews, with a PC balancing core polyhedral expertise with applications and broader computing systems research.

We welcome both theoretical and experimental papers and presentations on all aspects of polyhedral compilation. We also welcome submissions describing preliminary results, crazy new ideas, position papers, experience reports, education material, and available tools, with an aim to stimulate discussions, collaborations, and advances in the field. The following illustrate potential IMPACT papers:

  • Thorough theoretical discussion of a preliminary idea with an attempt to place it in context but no experimental results.

  • Experimental results comparing two or more existing ideas, followed by a detailed analysis.

  • Presentation of an existing idea in a different way, including illustrations of how the idea applies to new use cases, code, architectures, etc. Attribution should be as clear as possible.

Topics of interest include, but are not limited to:

  • program optimization (automatic parallelization, tiling, etc.);
  • code generation;
  • data/communication management on GPUs, accelerators and distributed systems;
  • hardware/high-level synthesis for affine programs;
  • static analysis;
  • program verification;
  • model checking;
  • theoretical foundations of the polyhedral model;
  • extensions of the polyhedral model;
  • scalability and robustness of polyhedral compilation techniques.

Paper Submission

Paper submissions should not exceed 10 pages (recommended 8 pages), excluding references, formatted as per ACM SIGPLAN proceedings format. Short paper submissions, even with only 2 pages, are welcome as well.

Use version 1.54 or above of the following templates to prepare your manuscript:


Make sure to use the “sigplan” subformat. Visit


for further information on SIGPLAN manuscript formatting. NOTE: older versions of the article template use smaller fonts for submission, please double-check that you are using the recent style file (in particular, various LaTeX distributions ship older versions of the acmart style file, please download the most recent one from ACM).

Submissions should use PDF format and be printable on US Letter or A4 paper. Please submit your manuscripts through EasyChair and while selecting “Paper” as submission type:


Proceedings will be posted online. If the final version of an accepted paper does not sufficiently address the comments of the reviewers, then it may be accompanied by a note from the program committee. Publication at IMPACT will not prevent later publication in conferences or journals of the presented work. However, simultaneous submission to IMPACT and other workshop, conference, or journal is often prohibited by the policy of other venues. For instance, a manuscript overlapping significantly with IMPACT submission cannot be submitted to PLDI 2023 or any other overlapping SIGPLAN event.

Please make sure that at least one of the authors can attend the workshop if your work is accepted to give a 25 minutes presentation of your work.

Presentation-only Submission

Submit a summary of your presentation through EasyChair:


Submissions have no formatting requirements but should use PDF formal. Choose “Presentation-only” when submitting.

The presentation should take no longer than 25 minutes to present. Please make sure that at least one of the authors can attend the workshop if your work is accepted.
