Cylc is a general purpose workflow engine that also
orchestrates cycling systems very efficiently.
It is used in production weather, climate, and environmental
forecasting on HPC, but is not specialized to those domains.
Cylc is an active Open Source project
See Cylc Publications and Reports below.
Cylc unwinds the cycle loop to get a dependency graph with
no barrier between cycles. This allows interleaved cycles
If you use Cylc please cite it in your
publications and let us
