  Abstract: This paper describes a building-block approach to the design of scientific workflow systems. We discuss RADICALCybertools as one implementation of building-block concept, showing how they are designed and developed in accordance with this approach. This paper offers three main contributions: (i) showing the relevance of the design principles underlying the building blocks approach to support scientific workflows on high performance computing platforms; (ii) illustrating a set of building blocks that enable multiple points of integration, “unifying” conceptual reasoning across otherwise very different tools and systems; and (iii) case studies discussing how RADICAL-Cybertools are integrated with existing workflow, workload, and general purpose computing systems, and used to develop domain-specific workflow systems.
