PACT 2022

The 31st International Conference on Parallel Architectures and Compilation Techniques (PACT) will be held during October 10–12, 2022. PACT is a long-running and unique conference at the intersection of classical parallel architectures and compilers that brings together researchers from architecture, compilers, programming languages, and applications to present and discuss their latest research results. Applications as a driver for innovations in architecture and compilers are an important theme of the conference.

2022 will mark the 31st edition of the International Conference on Parallel Architectures and Compilation Techniques (PACT). PACT is a unique technical conference that sits at the intersection of parallel architectures and compilers. The PACT conference series brings together researchers from architecture, compilers, execution environments, programming languages, and applications, to present and discuss their latest research results.

Our current plan is to hold PACT 2022 as an in-person event, after two consecutive virtual conferences. However, because of the uncertainty on the evolution of the pandemic and various travel restrictions, we still may need to revise those plans. We will make this decision some time in the Spring of 2022.

We solicit contributions in a broad range of topics, including (but not limited to) the following:

  • Parallel architectures and computational models
  • Compilers and tools for parallel computer systems
  • Multicore, multithreaded, superscalar, and VLIW architectures
  • Compiler/hardware support for hiding memory latencies
  • Support for correctness in hardware and software
  • Reconfigurable parallel computing
  • Dynamic translation and optimization
  • I/O issues in parallel computing and their relation to applications
  • Parallel programming languages, algorithms, and applications
  • Middleware and run time system support for parallel computing
  • Application-specific parallel systems
  • Applications and experimental systems studies of parallel processing
  • Relevant aspects of distributed computing and mobile computing
  • Heterogeneous systems using various types of accelerators
  • In-core and in-chip accelerators and their exploitation
  • Applications of machine learning to parallel computing
  • Insights for the design of parallel architectures and compilers from modern parallel applications
  • Future parallel systems for beyond Moore's law and/or beyond Exascale
  • Quantum computing architecture and technology
  • Programming quantum computers, including compilation, languages, and control software
  • Simulation of quantum circuits

Submitting your work

Paper submissions are due April 25, 2022. Please make sure that your paper satisfies all the following requirements before being submitted. Submissions not adhering to these submission guidelines will be rejected by the submission system and/or subject to an administrative reject.

  • The paper must have an abstract under 300 words.

  • The paper must be original material that has not been previously published in another conference or journal, nor is currently under review by another conference or journal. You may submit material presented previously at a workshop without copyrighted proceedings.

  • The submission is limited to ten (10) pages in the ACM 8.5" x 11" format (US letter size paper) using 9pt font, with no more than 7 lines per inch. This page limit applies to all content NOT INCLUDING references, and there is no page limit for references. Your paper must print satisfactorily on both Letter paper (8.5"x11") and A4 paper (8.27"x11.69"). The box containing the text should be no larger than 7.15"x9" (18.2cm x 22.9cm).

    Submission template

  • Anonymized supplementary material may be provided in a single PDF file uploaded at paper submission time, containing material that support the content of the paper, such as proofs, additional experimental results, data sets, etc. Reviewers are not required to read the supplementary material but may choose to do so.

  • Papers are to be submitted for double-blind review. Blind reviewing of papers will be done by the program committee, assisted by outside referees. Author names as well as hints of identity are to be removed from the submitted paper.

  • Use care in naming your files. Source file names (e.g., Joe.Smith.dvi) are often embedded in the final output as readily accessible comments. In addition, do not omit references to provide anonymity, as this leaves the reviewer unable to grasp the context. Instead, if you are extending your own work, you need to reference and discuss the past work in third person, as if you were extending someone else's research.

  • We realize in doing double-blind review that for some papers it will still be obvious who the authors are. In this case, the submission will not be penalized if a concerted effort was made to reference and describe the relationship to the prior work as if you were extending someone else's research. For example, if your name is Joe Smith:

    "In previous work [1,2], Smith presented a new branch predictor for .... In this paper, we extend their work by ..."


    • [1] Joe Smith, "A Parallel Architecture for ...," Proceedings of PACT 2004.
    • [2] Joe Smith, "A Compilation Technique for ...," Proceedings of PACT 2005.
  • Your submission must be formatted for black-and-white printers and not color printers. This is especially true for plots and graphs in the paper.

  • Please make sure that the labels on your graphs are readable without the aid of a magnifying glass.

  • Please number the pages.

  • The paper must be submitted in PDF. We cannot accept any other format, and we must be able to print the document just as we receive it. We suggest that you use only the four widely used printer fonts: Times, Helvetica, Courier and Symbol.

Please submit your work via the paper submission site at

Conflicts of Interest

To ensure a fair and high-quality reviewing process we ask ALL authors of a submitted paper to register their conflicts at the submission site. If a paper is found to have an undeclared conflict that causes a problem OR if a paper is found to declare false conflicts in order to abuse or game the review system, the paper may be rejected. Please declare a conflict of interest with the following people for any author of your paper. Do not limit yourself to only the PC members. A conflict occurs in the following cases:

  • Between adviser and advisee forever.

  • Between family members forever.

  • Between people who have collaborated in the last 5 years. This collaboration can consist of a joint research or development project, a joint paper, or when there is direct funding from the potential reviewer (as opposed to company funding) to an author of the paper. Co-participation in professional activities, such as tutorials or studies, is not cause for conflict. When in doubt, the author should check with the PC chair.

  • Between people from same institution or who were in the same institution in the last 5 years.

  • Between people whose relationship prevents the reviewer from being objective in his/her assessment. Service collaborations, such as co-authoring a report for a professional organization, serving on a program committee, or co-presenting tutorials, do not themselves create a conflict of interest. Co-authoring a paper that is a compendium of various projects with no true collaboration among the projects does not constitute a conflict among the authors of the different projects.

Artifact Evaluation

Authors of accepted PACT 2022 papers are invited to formally submit their supporting materials for Artifact Evaluation. Submission is voluntary. The Artifact Evaluation process is run by a separate committee whose task is to assess if artifacts supporting the work described in the papers are available and functional, and (some of) experimental results are reproducible.

We encourage authors to prepare their artifacts for submission and make them more portable, reusable and customizable using open-source frameworks including OCCAM, Docker, reprozip, CodeOcean and CK.

Papers that successfully go through the Artifact Evaluation process will receive a seal of approval printed on the papers themselves. Authors of such papers will have an option to include their Artifact Appendix to the final paper (up to 2 pages). Authors are also encouraged to make their artifacts publicly available, for example using the Code Ocean platform.
