Elevating community-centered scientific workflow solutions through collective expertise.

Our goal is to bring the workflows community together (users, developers, researchers, and facilities) to provide community resources and capabilities to enable scientists and workflow systems developers to discover software products, related efforts, events, technical reports, etc. and engage in community-wide efforts to tackle workflows grand challenges.

One workflow to rule them all: introducing DAGonStar, yet another workflow engine for Python developers, designed for HPC and AI.
