Different EMU Types of Histograms & Canvases
• EMU DQM Canvas (Histograms) Hierarchy– DDU
• CSC Chamber (ID by crate and slot of DMB)– ALCT
» 8 canvases– CFEB
» 4 canvases– CLCT
» 9 canvases– SYNC
» 5 canvases– DMB
» 5 canvases– CSC Efficiency canvas
• 14 DDU canvases
• Total of 46 different “types” of canvases per DDU– Each canvas contains 1 or more histograms– Each DDU contains several chambers– Not yet finished defining additional canvases…
• “Summary” : produces a (global) high-level report – for all tests with references or rules– for all “types” of canvases – for all chambers.
Different Kinds of Tests using Different Reference Sources
• Static Reference Sources– A Previous Run– Ideal Conditions (from detector knowledge)– etc
• Dynamic Reference Sources– Current Run– Rules (from detector knowledge)– Etc– Important because running conditions often change
• Tests– Current Run vs. A Previous Run– Current Run vs. Ideal Conditions– Current Run vs. Current Run– Current Run vs. Rules– etc

Current Design from EMU DQM Architecture
• RefHistComparator produces summary report every ~5 min
– Updates DB
• RefServer continuously updates histos
– Sends reference canvases to Display GUI
• Display GUI should be as light as possible
– Should be agnostic about different canvases and references
• GUI easier to maintain and always works
– All the hard work is done on the DisplayServer

Current Design Thoughts
• Design a base class container for reference canvases of all chambers– Of a particular canvas type!
• Design different reference comparison classes for each “type” of canvas
• For each canvas “type”, specify associated– References– Rules– Tests– (local) Summary Results
Current Design Thoughts
Contains reference canvases (of a certain type) for all chambers
Current Design Thoughts
Rules and Tests used to comparereference to online canvasesassociated with a certain type
Current Design Thoughts
Produce summary report for all tests performed for this particular type of canvas
Current Design Thoughts
List of all tests performed on alltypes of canvases
Current Design Thoughts
Produce global summary report for all tests performed for all types of canvases
Current Design Thoughts
Buffers to be sent to GUI to compare online canvases with different references (0,1,…,N)

Current Implementation
• Given an online histogram, RefHistComp can – Find & read static corresponding reference
histogram– Send reference histogram to GUI for human
comparison
• RefHistComp does not yet– Automatically compare online with
reference– Produce summary report– Fully work with Dynamic References

Conclusion
• The Ref-Hist Comparator Unit is designed to– Allow comparisons with a variety of different references
• Both manual and automatic• Both static and dynamic
– Periodically produce summary report of problems • Based on rules & tests
• Current prototype is still rather basic– Not all functionality is implemented / debugged
• E.g. Dynamic refs are prototyped, but not yet ready for release– Still iterating on final design (which may depend on CMS DQM)– Currently being tested & used in the EMU slice test
• Prototype is somewhat particular to current EMU DQM Package
• Interested to understand better how these ideas fit in with the overall CMS DQM picture
