7. Running Global Workflow on Supported HPC

This section describes how to run an experiment using the Global Workflow. The GW continues to evolve, and the underlying weather model (UFS-WM) supports multiple configurations. Therefore, this documentation will be updated periodically to reflect current capabilities.

The workflow can be executed in two modes:

• forecast-only mode

• cycled mode (Forecast + Data Assimilation)

Bacuse cycled mode requires a number of DA supporting repositories, the setup procedure differ slightly between the two modes for the initial build stage.

For guidance on testing individual workflow tasks using the CTest framework, refer to Testing Global Workflow Jobs.
