[hpc-announce] REPRO-HPC26 Workshop at ISC 2026: Call for Contributions

[Weidendorfer, Josef]

===================================================
                         1st Workshop on
         Sustainable practices for Reproducibility in HPC
                           (REPRO-HPC)

                      In conjunction with
                            ISC 2026
                June 26, 2026, Hamburg, Germany

===================================================

Reproducibility is a cornerstone for trustworthy and robust
scientific progress. However, the High-Performance Computing (HPC)
community faces challenges due to complex software stacks,
cutting-edge hardware, and costly operations (computations, data
transfers, etc.). These challenges could also be explained by a
lack of education on what reproducibility is, a lack of tools
offered by platforms to support reproducibility, inconsistencies in
the various venues’ guidelines for packaging the artifacts, or a lack
of incentives for the authors to make an extra effort. Overall,
reproducibility in HPC is mostly a methodological and technical
problem, which can only be addressed by gathering the community and
discussing all together about the way forward.

This workshop brings together the HPC community (researchers,
practitioners, platform providers, and educators) to share their
feedback, tools, and best practices to tackle the reproducibility
hurdles met in HPC.



===== Important Dates =====

Abstract Submission:   April 17, 2026 (AoE)
Authors Notification:  May 8, 2026 (AoE)
REPRO-HPC Workshop:    June 26, 2026, 9am - 1pm



===== Scope and Topics =====

General

- Feedback/Lessons learned/Success stories from artifact authors,
 reviewers, and chairs, trying to package an experiment or
 trying to reproduce an experiment
- Methods to create a "minimal reproducible experiment" to proxy
 the reproduction on the energy consuming full-scale version
- Energy-efficient artifact reproduction in HPC
- Case studies of sustainable (or unsustainable) artifact
 evaluation in HPC
- Long-term reproducibility: ensuring artifacts remain accessible
 and evaluable as hardware/software evolves
- Feedback from teaching HPC reproducibility principles
- Reproducibility in the age of AI: concerns and opportunities

Software Environment / Workflow / CI/CD

- Methods and tools to create a standalone and portable
 experiments (package managers, containers,...)
- Methods and tools to support reproducibility in HPC from the
 early development stages (CI/CD, provenance, SBOM, ...)
- Methods and tools to support FAIR principles

Platforms (HPC Centers and Testbeds)

- Tools and services that should be offered by HPC centers and
 testbeds to improve/support reproducibility
- Billing, access, and "security" to HPC centers and testbeds for
 reproduction attempts

Artifact Evaluation Process

- Proposals for new Artifact Evaluation processes (timelines,
 badges, reports, interactions between authors and reviewers,
 reviewer roles, etc.)
- Incentives and recognition for Reproducibility in HPC (for
 authors and reviewers)
- Human-centric sustainability: reducing reviewer/author fatigue
 and chair workload
- Community standards for balancing rigor, efficiency, and human effort
- "Proper" evaluation of proprietary software/hardware
