Practical Solutions for Computational Workflows
Enhancing Research with Computational Workflows
The integration of data-intensive computational studies is vital across scientific disciplines. Computational workflows systematically outline methods, data, and computing resources. With complex simulation models and vast data volumes, Computational Sciences and Engineering (CSE) workflows facilitate research beyond simulations, enabling analysis of diverse data and methodologies.
FAIR principles ensure research data are Findable, Accessible, Interoperable, and Reusable, guiding data stewardship. Emerging tools like Jupyter notebooks and Code Ocean facilitate documentation and integration, while automated workflows aim to merge computer-based and laboratory computations.
Addressing Reproducibility Challenges
The challenge of reproducibility in computational workflows requires thorough examination. Alternative tools like CWL and Galaxy offer advanced workflow management for various domains but also have limitations. FMI’s container-based approach aids in replicating simulations but requires metadata for broader reproducibility and adaptation.
Researchers from the Max Planck Institute for Dynamics of Complex Technical Systems introduce MaRDIFlow, a robust computational framework aiming to automate metadata abstraction within an ontology of mathematical objects. MaRDIFlow addresses execution and environmental dependencies through multi-layered descriptions.
MaRDIFlow: Enhancing Reproducibility
MaRDIFlow’s design principle revolves around treating components as abstract objects defined by their input-output behavior and metadata. This multi-level description enhances reproducibility, accommodating scenarios where software components may be unavailable. The current version of MaRDIFlow serves as a command-line tool, allowing users to manage workflow components as abstract objects based on input-output behavior.
Use cases, such as CO2 conversion rates and spinodal decomposition, demonstrate its functionality while adhering to FAIR principles. Ongoing development aims to address diverse use cases in mathematical sciences.
