Workflow for Robust Code and Data Management exemplified for the numerical calculation of the Hopf index — •Jonas Nothhelfer, Ross Knapman, and Karin Everschor-Sitte — Universität Duisburg-Essen

Structured workflows for code and data management are essential in scientific projects to ensure reproducibility and quality. We will discuss these workflows from a system administrator’s perspective, emphasizing the infrastructure and tools needed to support scientific computing. Using a recent scientific project as a case study, we present an example workflow that makes the projects numerical methods for calculating the three-dimensional topological Hopf index accessible [1]. Not only do we offer Python scripts, but we also develop extensions for the standard micromagnetic software tool, Mumax3 [2]. Code management is handled through GitLab, ensuring access to the most current versions of code [3], while Zenodo is used to provide persistent identifiers for released versions [4].
