Summary (2-4 sentences)
Workflows are a key technology for enabling complex scientific computations. They capture the interdependencies between processing steps in data analysis and simulation pipelines as well as the mechanisms to execute those steps reliably and efficiently. Workflows can capture complex processes, promote sharing and reuse, and also provide provenance information necessary for the verification of scientific results and scientific reproducibility. Pegasus is a popular workflow tool developed in collaboration with HTCondor team, and provides Python3 workflow API developed from the ground up so that, in addition to generating the abstract workflow and all the catalogs, it now allows you to plan, submit, monitor, analyze and generate statistics of your workflow. Since 2022, Pegasus is a key part of the ACCESS support strategy (https://support.access-ci.org/pegasus).
