Task Implementation

This section covers the technical detail of how Cylc runs tasks.

In Cylc tasks represent activities within the workflow. Tasks submit jobs when they are run.

Tasks are the “abstract” workflow component. Jobs are the concrete representation of a task. One task could submit many jobs (for example if the job fails and the task is re-run).
