工作流系统为科学家提供了一条从假设到发现的自动化端到端路径。然而，期望任何单一工作流系统提供如此广泛的功能是不切实际的。一种更实用的解决方案是由多个系统组成端到端工作流程。考虑到这一目标，我们探索了基于任务的工作流和现场工作流的集成，其结果是由子工作流组成的分层异构工作流，不同层次的层次结构使用不同的编程、执行和数据模型。材料科学用例证明了这种异构分层工作流程组合的优势。
Workflow systems promise scientists an automated end-to-end path from hypothesis to discovery. However, expecting any single workflow system to deliver such a wide range of capabilities is impractical. A more practical solution is to compose the end-to-end workflow from more than one system. With this goal in mind, the integration of task-based and in situ workflows is explored, where the result is a hierarchical heterogeneous workflow composed of subworkflows, with different levels of the hierarchy using different programming, execution, and data models. Materials science use cases demonstrate the advantages of such heterogeneous hierarchical workflow composition.
