Cylc 8.0 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.
Browser Based UI
The old “GUI” has been replaced by the new browser-based “UI”.
- Graph View
There is no graph view in the new Cylc UI as yet. A new graph view will be developed providing both “live” (AKA
cylc gui) and “offline” (AKA
cylc graph) functionalities.
- 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.
- Log Files
The ability to view job logs and other files in the web UI is yet to be implemented. For the moment:
look in your
use Cylc Review from Cylc 7.9.5/7.8.10 (the latest version is compatible with Cylc 8)
- 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.
- Trigger Edit
Functionality removed pending reimplementation.
- 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.
A full-featured authorization system has been implemented for Cylc 8, but the UI doesn’t yet provide easy access to other users’ UI Servers.
- CLI via UIS
The ability to route Cylc commands via the UIS is planned for a future release
