Offline QAOffline QA
Approach Minimize code duplication (SDD & SSD)
Code for QA & DQM in AliRoot amoreAgent to drive the DQM, which calls AliRoot DQM GUI in Amore
Online Monitoring Used during the last cosmic run
Build QA distributions on real Data

What’s Next?What’s Next?ONLINE DQM/QA SPD
Until now, stay with MOOD SDD/SSD
AMORE + AliRoot Improve the GUI Optimize the updating frequency (-> speed) Add long-term detector controls (SDDs)
– Drift speed vs time– Baseline vs time– …
Minimize the number of histograms… Exploit the improvements in the new AMORE version
– Custom time interval for update– New Subscribe procedure
AMORE improvements wishlist Update histograms dynamically ONLY when they are requested from a GUI agent
(minimize task load…)

What’s Next?What’s Next?OFFLINE QA SPD/SDD/SSD
Improve the DataMaker implementation QA Checker implementation
– Define the reference distributions
• This is the difficult part
• The detector behaviour is not understood (yet)
• It can be implemented on simulated data, but it is meaningless (you get what you put…)
• Reference distributions should be blessed by the hardware people
– Implement the QA set of checks and provide the QA result
• Who does the SPD/SDD/SSD merging?
