CMS Run Mode


Feedback page for the Level-0 with run mode


The Level-0 now has a new Run Mode feature which ties together the L1/HLT Mode, Clock Source and Subsystem run keys. You can select a run mode from the “CMS Run Mode” drop-down at the top-right of the GUI, or have it automatically selected based on the LHC Beam and Machine mode, by ticking the autoselect checkbox.

You can set the run mode to MANUAL to get the “old” functionality and avoid using a run mode. To automatically select the clock source when run mode is MANUAL, tick the autoselect checkbox in the Clock Source row.

To report a bug or for any feedback, use this wiki: RunModeFeedback


  • improve run mode matrix display
  • Run mode to runinfo
  • BIG ALERT also when current run mode (set) differs from suggested one?
  • thread safety of periodic calls
