Display Management Framework Options

MEDM

• Based on Motif.
• Extensively used in all hall in Jefferson Lab.
• Well understood by the Hall D online group.
• Easy to set up and easy to use.
• Limited functionality.
• This is an old technology, and it would be desirable to not used as the main display manager for Hall D control systems. It might be useful for doing quick studies due to its ease of use.

EDM

• Current display management in accelerator.
• Requires Motif or equivalent.
• Improvement over MEDM, enhanced functionality.
• Somewhat more difficult to setup than MEDM.
• There were issues raised by people from cryo group regarding how fast a screen loads when there are too many widgets on the screen.
• Old technology. The only reason this can be considered as an option is if accelerator division decides to use this in the 12 GeV era.

CSS

• CSS itself is not a Display manager, it is a suite of plugins for control systems.
• Used in DESY, Oakridge and BNL. Each of these three labs have their version of CSS builds.
• There are two Display management tools in CSS: BOY and SDS, but their use the same set of plugins.
