Cylc 8.2 Caveats
There are a few Cylc 7 features which do not yet have direct replacements in Cylc 8. These features will be re-implemented in future releases.
- Multiple Flows
The new scheduler can manage multiple flows in the workflow graph. Commands and options for interacting with flows are still being refined.
Browser Based UI
The old “GUI” has been replaced by the new browser-based “UI”.
- Static Graph Visualization
Not yet reimplemented for Cylc 8. As an interim measure the
cylc graphcommand can generate a basic PNG image of a workflow graph if Graphviz is installed in the Cylc environment.
- Multiple Selection
Multiple selection is yet to be implemented, however, it is possible to issue action for multiple tasks (e.g.
kill) without using multiple selection:
From the UI click on a workflow/cycle/task/job.
Find the action you want to call (e.g. kill).
Click the pencil symbol next to this action.
Edit the workflows/cycles/tasks/jobs in the form and press submit.
- Installing Workflows
At present there is no way to view or install source workflows in the UI.
- Rose Edit
Rose Edit is awaiting reimplementation in the UI.
- Xtrigger Visibility
Xtriggers are not yet visible in the UI.
- Documentation / Orientation Guide
Some form of documentation will be provided within the UI itself.
Terminal User Interface
cylc tui command (Tui) replaces the old
cylc monitor. It provides a
tree view that is very similar to the Cylc UI and supports some control
TUI currently refreshes its display every second. Large workflows which change rapidly may evolve faster than TUI is able to keep pace with which will cause TUI to freeze.
A more performant implementation which does not rely on a scheduled global update will follow in due course.
cylc gscanGUI has been removed. You can now find the gscan display on the left-hand side of the Cylc UI.
In a future release
cylc tuiwill be able to list workflows in a similar way.
- CLI via UIS
The ability to route Cylc commands via the UIS is planned for a future release
