One can create workflows which can run unmodified on local compute, HPC clusters, or the cloud. As these languages are not tied to a specific execution environment, the descriptions can easily be shared, discovered and even composed together to form more complex workflows. The
Workflow Description Language (WDL) is an open, community driven standard that is designed from the ground up as a human-readable and -writable way to express portable tasks and workflows.
In this session we’ll walk through the lifecycle of writing, sharing and discovering portable workflows in WDL. We’ll introduce the WDL syntax. You’ll learn how to write and run a workflow locally. We’ll demonstrate how to use
EPAM’s Pipeline Builder toolto visualize WDL workflows. We’ll look at
Dockstore, an open platform where one can publish, share and discover workflows. Finally we’ll put everything together and see how we can compose workflows we find on Dockstore together with our own additions to create new, more powerful workflows.
