Call For Papers

The 32nd IEEE International Symposium on High-Performance Computer Architecture (HPCA) will be held in Sydney, Australia in 2026, from January 31 – February 4, 2026.

HPCA is a high-impact premier venue for presenting research results on a wide range of Computer Architecture topics.

Topics of Interest

• Processor, memory, and storage systems architecture and microarchitecture
• Interconnection networks and network interface architecture
• Domain-specific architectures and accelerators
• FPGA, CGRA, and reconfigurable systems
• Near-/in-memory computing
• Cloud, datacenter, cluster/distributed computer systems
• Compilers/OS/runtimes as they relate to Computer Architecture
• IoT, mobile, edge, and embedded architectures
• Effects of circuits or technology on architecture (3D/chiplets/interposer/wafer-scale)
• Architecture modeling and simulation methodologies
• Architectures using quantum, superconducting, and emerging technologies
• Reliability/fault tolerance as they relate to Computer Architecture
• Security and privacy as they relate to Computer Architecture
• Evaluation and measurement of real computing systems
• Verification, testing, and correctness as they relate to Computer Architecture
• Power and energy as they relate to Computer Architecture
• Sustainable computing as they relate to Computer Architecture

We encourage authors to contact the program chairs (Aamer Jaleel and Mattan Erez) if they have a question regarding topic fit.

Industry Track

HPCA 2026 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.

Important Dates

• Abstract Submission: July 25, 2025 23:59 UTC / 19:59 EDT
• Paper Submission: August 1, 2025 23:59 UTC / 19:59 EDT
• Revision/Rebuttal Period: October 7 – 20, 2025
• Notification: November 7, 2025
• Final Papers Due: December 4, 2025

Submission Guidelines & Policies

All paper submissions must adhere to several important aspects:

Final Submission Mindset

Submitting papers for review that are not yet complete and polished abuses the review process and is disrespectful to the Program Committee and the Computer Architecture community. All authors must affirm that their submission is, to the best of their abilities, complete, polished, and ready for comprehensive review. Furthermore, if all reviewers of a submission find that the submission is lacking in this regard, detailed reviewer feedback will be withheld from the authors. In other words, there is a cost to submitting unfinished work – it may “poison” future reviews without the authors gaining any feedback.

Reviewer Continuity Initiative

HPCA 2026 is considering an initiative to maintain reviewer continuity for submitted papers that were rejected from MICRO 2025 on an opt-in basis. The goal for this initiative is to improve the fairness of the overall review process in Computer Architecture. It is in the best interest of authors and the community to have papers undergo a consistent revision process. However, please do not feel pressured to participate in this initiative, reviewers will not be made aware of your choice implicitly or explicitly.

If all authors of a submission opt in to the “reviewer continuity initiative”, reviewers who had previously reviewed a version of the submission for MICRO 2025 may be explicitly assigned to review the submission (PC members also must opt in to this initiative). If the authors do not opt in for “reviewer continuity”, reviewers of previous submissions may still be assigned to review the submitted version of the paper based on reviewer expertise, reviewer load balance, and other similar agnostic criteria.

Revision Letters

If a submission has been previously reviewed and rejected from another venue or conference and is now being submitted to HPCA 2026, the authors must provide a letter explaining how the paper has been revised for this current submission, regardless of whether the authors opt to participate in “reviewer continuity” or not. Authors may choose to only permit the PC Chairs to have access and knowledge of this letter. Authors who opt in for reviewer continuity implicitly make their revision letter available to reviewers who reviewed a prior version for MICRO 2025. Note that it is not a requirement that papers be revised before being submitted to HPCA, but we expect a revision letter nonetheless.

Abstract Registration and Final Submission

Authors must register an abstract one week before the paper submission deadline. The purpose is to ensure that authors are fully aware of all submission requirements, topic selection, conflict of interest registration, etc. All information regarding the submission may be edited up to final submission time but may not change once the review process has started. In particular, authorship at submission time must match that of the final publication, if accepted.

Formatting and Submission Instructions

Detailed formatting and submission instructions will be made available on the submission site (http://hpca2026.hotcrp.com) at a later date.
