Cyclic Workflow
---------------
.. currentmodule:: nvflare.app_common.workflows.cyclic_ctl.CyclicController

The cyclic workflow was added in NVIDIA FLARE 2.0 and implemented with the Controller API. It allows for a different control
flow implemented through the :meth:`control_flow()<control_flow>` method based on ``relay_and_wait()`` instead of
``broadcast_and_wait()`` in the :ref:`scatter_and_gather_workflow`.

:class:`nvflare.app_common.workflows.cyclic_ctl.CyclicController`

See the :github_nvflare_link:`Hello Cyclic Example <examples/hello-world/hello-cyclic>` for an example application with
the cyclic workflow.
