ParaO: In situ reproducible workflows through user-centric design — Martin Erdmann, •Benjamin Fischer, and Felix Zinn — III. Physikalisches Institut A, RWTH Aachen University

In High Energy Physics (HEP) and other fields, data analyses require many different steps to produce a final result. As such, it is sensible to leverage workflow tools to codify these complex structures of tasks and their dependencies. Of course, such intricate analyses are not created ad hoc; rather, their development is a lengthy and iterative process.

Here, ParaO's design empowers users to rapidly grow and readily adapt their work while avoiding verbose boilerplate. For example, integrating a new parameter or dependency in the middle of a ten-step workflow needs just a single line of code. There, ParaO automatically propagates the resulting knock-on effects, such as changed implicit parameterization of later tasks---unlike Luigi, which requires a more manual treatment.

Thus, ParaO enables in situ usage of workflows and their benefits, such as bookkeeping and reproducibility, even in early and chaotic stages of development. We demonstrate ParaO's principles and features in the context of a comprehensive top-Higgs analysis.
