Implementing a Reproducibility Initiative in HPC: Experiences from SC24
Résumé
Reproducibility is fundamental to scientific research, but can be particularly challenging in research that involves High Performance Computing (HPC) due to the unique characteristics of supercomputers. Performance-based metrics such as execution time, energy consumption, and throughput further complicate reproducibility, especially on shared systems.
In this paper, we present our experience implementing a reproducibility initiative at SC24, with particular emphasis on changes made compared to prior SC conferences. We outline HPC-specific challenges, describe the measures adopted to address them, and reflect on the limitations of reproducibility badges. Faced with the constraints of the existing badging nomenclature, we discuss our implementation of a reproducibility report, which aims to provide more context about the reproducibility of each paper. We conclude by recommending that the "Artifact Replicable" badge be dropped by HPC conferences at this time, and discuss alternate ways of ensuring replicability evaluation.
