Cylc ("silk") orchestrates complex distributed suites of interdependent cycling (or non-cycling) tasks. It was originally designed to automate environmental forecasting systems at NIWA. Cylc is a general workflow engine, however it is not specialized to forecasting in any way.

Python 2 or Python 3 ?

Currently in the source code repository:

• master branch: Python 3, ZeroMQ network layer, no GUI - Cylc-8 Work In Progress
• 7.8.x branch: Python 2, Cherrypy network layer, PyGTK GUI - Cylc-7 Maintenance

The first official Cylc-8 release (with a new web UI) is not expected until late 2019. Until then we recommend the latest cylc-7.8 release for production use.
