Offline DQM

1
Offline DQM

• Offline DQM (current SliceTest setup)

Copy of data files from local disk to shared
disk DQM Offline analysis on a dedicated node
2
Offline DQM (testing)

• Offline DQM (testing on DAQ Farm)

Data stays on local disks Faster generation of
offline results because of parallel processing -
Could slow down online DQM, while processing data
3
Offline DQM (testing)

• Online DQM results publishing (DAQ Farm)

ROOT Files
Save ROOT files at the end of the Run Results
will be available almost immediately - Not all
events will be analyzed (Depends on readout rate)

Offline results Browser

• Improved offline DQM results browser
• Overall CSC System view
• VME Crate/DMB Slot view
• Slide show mode
• Resizing of plots

• Current Slice Test setup (tested with real data)
• Slice Test Local DAQ-DQM Setup
• 4 DAQ Readout processes on 2 PCs get data from 4
  DDUs in Spy mode
• 4 DQM Monitoring processes get data online from
  DAQ
• DQM computer with online results display Web
  application

Online DQM (Initial Setup)

• DAQ Farm at CERN (initial setup)

Canvases
Same scheme as on SliceTest For initial DAQ-DQM
tests on DAQ Farm
7
Online DQM (Final Setup)

• DAQ Farm at CERN (final goal setup)

DQM Node

Local DQM

• Local DQM
• Most of the Local DQM suite is installed on DAQ
  Farm
• Slice Test version for SLC4, XDAQ 3.7 (DAQKit
  4.x)
• Test version for latest XDAQ 3.11
• Startup XML configuration file for ME side is
  prepared
• Unpacking is based on CMSSW_1_7_0x
• recent TMB, ALCT firmware changes
• Need to test DAQ-DQM online operation on DAQ Farm
  (stability, performance)

Global DQM

• Global DQM
• Major updates
• Code synchronization between Local and Global DQM
  code (booking, analysis)
• Fixes for changes in CMSSW DQM Framework
• Locally tested with current Global DQM GUIs
  (IGUANA, Web-based, local Client)
