HPCA 2027 features a separate Industry Track with a separate call for papers. The goal of the HPCA Industry Track is to publish papers that are written by industry authors and their content relates to industrial products/processes. See Industry Track submission instructions.

Note: Due to the recent, dramatic increase in paper submissions, we are introducing a new change. Each paper must designate a senior author that may be asked to serve as a light PC member (reviewing no more than 6 papers) if not already on the PC. If assigned reviews, this designated author has to produce timely and high quality reviews to avoid delays in the release of their own paper’s reviews.

The full submission instructions may be found at: https://2027.hpca-conf.org/call-for-papers/.

Guidelines for Submissions

The purpose of having a paper registration deadline a week ahead of the actual paper submission is to overlap review assignments (which can take a long time) with giving you extra time to improve the quality of your submission. To adhere with this intention, we need you to:

• Please make the paper title as close to the final version as possible.

• The author list cannot change (order of authors can) after registration. If there needs to be a change, you should send an email indicating the change at least 48 hours before the paper submission deadline to the PC chairs.

• Conflict List must also be finalized by the abstract registration. Please ensure it is accurate at the time of registration.

• Please make the abstract as close to the final version as possible.

Flagrant violation of the above could result in an outright desk rejection of the submission (for example, having a title/abstract or especially conflict list that does not correspond to the final submitted paper).

Paper format at a glance (more details and LaTeX template below):

• Papers must be submitted in printable PDF format.

• Text must be in a minimum 10pt font.

• Papers must be at most 11 pages, not including references.

• Line spacing (leading) must be no less than 12pt.

• No page limit for references.

• References must include all authors (i.e., do not use et al.).

Paper Evaluation Objectives

The committee will make every effort to judge each submitted paper on its own merits. There will be no target acceptance rate. We expect to accept a wide range of papers with appropriate expectations for evaluation – while papers that build on significant past work with strong evaluations are valuable, papers that open new areas with less rigorous evaluation are equally welcome and especially encouraged. We also acknowledge the wide range of evaluation methodologies in HPCA including modeling, simulation, prototyping, experimental implementation, real product evaluation, etc.

Paper Formatting

Papers must be submitted in printable PDF format and should contain a maximum of 11 pages of single-spaced two-column text, not including references. You may include any number of pages for references, but see below for more instructions. If you are using LaTeX to typeset your paper, then we suggest that you use our template. The sample paper was prepared with that template.

If you use a different software package to typeset your paper, then please adhere to the guidelines given in the table below. Please ensure that you include page numbers with your submission. This makes it easier for the reviewers to refer to different parts of your paper when they provide comments. Please ensure that your submission has a banner at the top of the title page, which contains the submission number and the notice of confidentiality. If using the template, just replace ‘NaN’ with your submission number.

Content

Reviewing will be double blind: therefore, please do not include any author names on any submitted documents except in the space provided on the submission form. You must also ensure that the metadata included in the PDF does not give away the authors. If you are improving upon your prior work, refer to your prior work in the third person and include a full citation for the work in the bibliography. For example, if you are building on your own prior work in the papers, you would say something like: “While the authors of [x][y] did X, Y, and Z, this paper additionally does W, and is therefore much better.” Do NOT omit or anonymize references for blind review. There is one exception to this for your own prior work that appeared in IEEE CAL, arXiv, workshops without archived proceedings, etc., as discussed later in this document.

Figures and Tables

Ensure that the figures and tables are legible. Please also ensure that you refer to your figures in the main text. Many reviewers print the papers in gray-scale. Therefore, if you use colors for your figures, ensure that the different colors are highly distinguishable in gray-scale.

References

There is no length limit for references. Each reference must explicitly list all authors of the paper. Papers not meeting this requirement will be rejected. Since there is no length limit for the number of pages used for references, there is no need to save space here.

Paper Submission Instructions

Guidelines for Determining Authorship

IEEE guidelines dictate that authorship should be based on a substantial intellectual contribution. It is assumed that all authors have had a significant role in the creation of an article that bears their names. In particular, the authorship credit must be reserved only for individuals who have met each of the following conditions:

1. Made a significant intellectual contribution to the theoretical development, system or experimental design, prototype development, and/or the analysis and interpretation of data associated with the work contained in the article;

2. Contributed to drafting the article or reviewing and/or revising it for intellectual content; and

3. Approved the final version of the article as accepted for publication, including references.

A detailed description of the IEEE authorship guidelines and responsibilities is available here. Per these guidelines, it is not acceptable to award honorary authorship or gift authorship. Please keep these guidelines in mind while determining the author list of your paper.

Declaring Authors

Declare all the authors of the paper upfront. Paper title, and authors cannot change after abstract registration. The abstract may not change beyond reasonable editing; in other words, the registered abstract must reflect the submitted paper. Flagrant violation of this will result in an outright desk rejection of the submission (for example, having a title/abstract or especially conflict list that does not correspond to the final submitted paper).

Reserve Reviewer Process

Following the policy created for ISCA’26, each paper must identify a senior author that may be asked to serve on the light PC (reviewing no more than 6 papers). If assigned reviews, this designated author has to produce timely and high quality reviews to avoid delays in the release of their own paper’s reviews. Exemptions exist for if one of the following conditions applies:

• The paper has no senior authors.

• At least one senior author is already on the main or light program committee.

• All senior authors of the paper satisfy one or more of these criteria:

  • Has never published in a conference sponsored by TCCA, TCMM, SIGRACH, or SIGMICRO.

  • Is (co)chairing a TCCA, TCMM, SIGRACH, or SIGMICRO conference with 150 or more submissions last year, this year, or next year.

  • Has some other exceptional circumstance that didn’t prevent writing the paper but prevents doing any reviewing. This must be cleared at least three days before the registration deadline with the PC Chairs.

Areas and Topics

Authors should indicate these areas on the submission form as well as specific topics covered by the paper for optimal reviewer match. If you are unsure whether your paper falls within the scope of HPCA, please check with the program chair – HPCA is a broad, multidisciplinary conference and encourages new topics.

Declaring Conflicts of Interest

Authors must register all their conflicts on the paper submission site. Conflicts are needed to ensure appropriate assignment of reviewers. 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 desk rejected.

Please declare a conflict of interest with the following people for any author of your paper. A conflict occurs in the following cases:

1. Between doctoral and postdoctoral advisors and advisees, forever.

2. Between family members, forever (if they might be potential reviewers).

3. Between people who have collaborated in the last 4 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 program chairs.

4. Between people from the same institution or who were in the same institution in the last 4 years, or where one of them is being actively considered for employment (e.g. invitation for interview) by the other person’s institution.

5. When there is funding involving the potential reviewer (as opposed to merely funding from the reviewer’s company).

6. Between people who are members of the same research center where unpublished work is regularly discussed (e.g., at review meetings)

7. Between people whose relationship prevents the reviewer from being objective in his/her assessment.

8. There may be others not covered by the above with whom you believe a COI exists, for example, an ongoing collaboration which has not yet resulted in the creation of a paper or proposal. Please report such COIs; however, you may be asked to justify them. Please be reasonable. For example, you cannot declare a COI with a reviewer just because that reviewer works on topics similar to or related to those in your paper. The program chair may contact co-authors to explain a COI whose origin is unclear.

The following scenarios do not constitute a conflict:

1. Authors of previously-published, closely related work on that basis alone.

2. “Service” collaborations such as co-authoring a report for a professional organization, serving on a program committee, or co-presenting tutorials.

3. Co-authoring a paper that is a compendium of various projects, community-wide tools (e.g., gem5), non-research articles, and working groups (e.g. RISC-V) with no true research collaboration among the co-authors.

4. People who work on topics similar to or related to those in your papers.

5. People under the same umbrella funding award where there is no close collaboration, no discussion of unpublished work, and no joint benefit in the paper being published.

Most reviews will be solicited among the members of the program committee, but other members from the community may also write reviews. Please declare all your conflicts (not just restricted to the PC) on the submission form. When in doubt, contact the program chair.

ArXiv and IEEE CAL Submissions

Authors may submit their work to HPCA 2027 for publication even if the paper has been submitted to or currently appears on Arxiv or in IEEE CAL. However, please do recognize that these submissions can cause issues with the double-blind review process. The PC chairs will advise the PC members not to consider Arxiv or CAL submissions in their evaluation. However, we encourage the authors to reduce the possibility of their name being disclosed. While there is no magical solution to hide from the power of web search in locating these papers, we encourage authors to avoid substantially similar titles, abstract etc., to reduce this match.

Policy on use of AI

Authors must comply with the guidelines on the use and disclosure of content generated by artificial intelligence (AI) specified in the IEEE Publication Services and Products Board Operations Manual, quoted below:

8.2.1.B.10:

The use of content generated by artificial intelligence (AI) in an article (including but not limited to text, figures, images, and code) shall be disclosed in the acknowledgments section of any article submitted to an IEEE publication. The AI system used shall be identified, and specific sections of the article that use AI-generated content shall be identified and accompanied by a brief explanation regarding the level at which the AI system was used to generate the content.

The use of AI systems for editing and grammar enhancement is common practice and, as such, is generally outside the intent of the above policy. In this case, disclosure as noted above is recommended.

In accordance with these policies, all submissions with AI generated content will include an appendix titled “AI use”, which will be after references and not included in the page count limit. This appendix will outline any usage of AI in the generation of the submission.

Concurrent Submissions and Workshops

By submitting a manuscript to HPCA 2027, the authors guarantee that the manuscript has not been previously published or accepted for publication in a substantially similar form in any conference, journal, or the archived proceedings of a workshop (e.g., in the IEEE digital library) – see exceptions below. The authors also guarantee that no paper that contains significant overlap with the contributions of the submitted paper will be under review for any other conference or journal or an archived proceedings of a workshop during the HPCA 2027 review period. Violation of any of these conditions will lead to rejection.

The only exceptions to the above rules are for the authors’ own papers in (1) workshops without archived proceedings such as in the IEEE digital library (or where the authors chose not to have their paper appear in the archived proceedings), or (2) venues such as IEEE CAL or arXiv where there is an explicit policy that such publication does not preclude longer conference submissions. In all such cases, the submitted manuscript may ignore the above work to preserve author anonymity. This information must, however, be provided on the submission form – the PC chair will make this information available to reviewers if it becomes necessary to ensure a fair review. If you have already put your manuscript on arXiv, in the interest of double blind review, modify the title for the version you submit to HPCA. As always, if you are in doubt, it is best to contact the program chairs (hpca2027chairs@gmail.com).

Finally, the IEEE Plagiarism Policy covers a range of ethical issues concerning the misrepresentation of other works or one’s own work.
