ACM REP ‘26 welcomes submissions across computing disciplines, spanning both traditional computer science and interdisciplinary scientific computing applications in biology, chemistry, physics, astronomy, genomics, geosciences, etc. The conference particularly values submissions that demonstrate reproducible experimental results. Where full reproduction is not achieved, detailed documentation of the reproducibility experience is equally valuable.

The conference addresses various aspects of reproducibility and replicability, including but not limited to the following topics:

Reproducibility Concepts

• Experiment dependency management.
• Experiment portability for code, performance, and related metrics.
• Software and artifact packaging and container-related reproducibility methods.
• Approximate reproducibility.
• Record and replay methods.
• Data versioning and preservation.
• Provenance of data-intensive experiments.
• Automated experiment execution and validation.
• Reproducibility-aware computational infrastructure.
• Experiment discoverability for re-use.
• Approaches for advancing reproducibility.

Reproducibility Experiences

• Experience of sharing and consuming reproducible artifacts.
• Conference-scale artifact evaluation experiences and practices.
• Experiences as part of hackathons and summer programs.
• Classroom and teaching experiences.
• Usability and adaptability of reproducibility frameworks into already-established domain-specific tools.
• Frameworks for sociological constructs to incentivize paradigm shifts.
• Policies around publication of articles/software.
• Experiences within computational science communities.
• Collecting datasets from laboratory / real-world settings.

Systems and Security Concerns

• Experience comparing published systems in a domain.
• Tools to support replicability of system analysis.
• Designing machine learning workflows to support reproducibility.
• Reproducing real-world security findings.
• Privacy concerns arising from reproducibility.
• Challenges of reproducing security experiments.
• Securing reproducibility infrastructure.

Reproducibility Campaigns

• Large-scale or focused efforts to reproduce results within a specific computer science or interdisciplinary domain.
• Challenges and lessons learned from reproducing published papers or benchmark studies.
• Comparative analyses of findings across independently reproduced works.
• Methodological or infrastructural experiences in coordinating multi-paper or community-wide reproduction efforts.
• Lifecycle studies of reproduction, from initial replication to long-term maintenance and validation of results.
• Infrastructure and tooling challenges encountered during systematic reproduction exercises.

Broader Reproducibility

• Cost-benefit analysis frameworks for reproducibility.
• Novel methods and techniques that impact reproducibility.
• Reusability, repurposability, and replicability methods.
• Long-term artifact archiving and verification/testing for future reproducibility.

All ACM REP 2026 papers will be published under ACM Open.

Starting January 1, 2026, ACM will fully transition to Open Access. All ACM publications, including those from ACM-sponsored conferences, will be 100% Open Access. Authors will have two primary options for publishing Open Access articles with ACM: the ACM Open institutional model or by paying Article Processing Charges (APCs). With over 2,600 institutions already part of ACM Open, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 76%).

Authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a financial waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the Policy on APC Waivers for Financial Hardship. Keep in mind that waivers are rare and are granted based on specific criteria set by ACM.

Understanding that this change could present financial challenges, ACM has approved a temporary subsidy for 2026 to ease the transition and allow more time for institutions to join ACM Open. The subsidy will offer:

• $250 APC for ACM/SIG members
• $350 for non-members

This represents a 65% discount, funded directly by ACM. Authors are encouraged to help advocate for their institutions to join ACM Open during this transition period. This temporary subsidized pricing will apply to all conferences scheduled for 2026.

For authors who are not able to cover their APCs, the ACM REP Emerging Interest Group will work with the ACM REP 2026 conference to identify ways of providing support.
