Online Athena monitoring in EF for TileCal commissioning

Online Athena monitoring in EF for TileCal
commissioning

• S.Sushkov _at_ IFAE
• 2005-10-21

2
Main idea motivation

• Event Filter has unique features
• accessing full event data built by SFI
• ability to run Athena offline algorithms within
  TDAQ DataFlow framework
• On this basis EF can provide many additional
• useful functionalities online monitoring and
• calibration

Lets distinguish different monitorings

• Gatherer overall collector of all/any
  histograms published in TDAQ IS (general
  information) not used
• GNAM standalone simplified monitoring tool not
  interfaced to Athena - not used (by us)
• emon event monitoring framework in TDAQ to make
  events available for user monitoring tasks -
  USED
• monitoring of physics objects by Athena
  reconstruction algorithms within Event Filter
• in EF Farms of real-ATLAS design more general
  complete, under discussions/planning now
• in RCD MobiDaq for detector commissioning
  activities early cosmic runs. Main difficulty
  no full TDAQ DataFlow available (no L2 / EB /
  FullEvent)

August tests (1)

• First successful run
• of Tile MobiDaq
• with EF-monitoring
• segment Monday
• August 1st afternoon
• TileMon histograms
• were seen online
• (updating) in oh_display
• Then EF-monioring
• segment run (stably !)
• within Tile MobiDaq
• partition over night
• during cosmic data
• taking

9
August tests (2)

• Minor problem after 10 hours
• of stable (!) running, PT crashed
• at TDAQ stop transition and
• histograms were not saved to file.
• (but saved w/o problems when
• EF-mon tested with file_sampler !)

PT IPC-timeout / EF Controller problem during
STOP transition - looks like one observed also in
Large Scale Tests increase timeouts use LC
fixes from LST.

WGs coordination

• Mini-WG TileCal-TDAQ-EF formed
• define code set of realistic histos
• Low-level (HW channels) in GNAM
• High-level (reco or time history) in EFAthena
• integration with
• TDAQ HLT TileCal offline code
• TileCal readout TDAQ
• Other detectors are joining LAr, Inner, MDT
• proceed in similar way as with TileCal
• TileCal is special because
• It is first commissioned
• GNAM developers are there
• Overall coordination by TDAQ Monitoring WG

11
Realistic histos for TileCal

• set of physics interesting histograms was
  defined
• Position of the Most energetic Tower (1-dim histo
  eta-phi) ? done
• Rates in All towers one-by-one /- almost
• All most energetic cells (Etime diff between
  two PMTs) /- almost
• Include TileMuID back-to-back objects ? done
• Noise-per-channel OVER TIME ? to do
• (Fraction of) coherent noise to average noise
  OVER TIME ? to do
• want to see your analysis online ? -gt CALL US
• code development status
• Method works
• TileCal reco algos (TileMuID) are included in
  jobOptions
• in TileMon, access to (reconstructed) objects
  from StoreGate
• Problems
• Hierarchy of TileCal C classed not yet
  absolutely clear
• Consequence / Syntax of jobOptions is not trivial
• Once above is clear (with help of TileCal
  experts), then
• no problem foreseen to program / fill histos
  inside TileMon code !

TileCal monitoring with Event Filter, TileMuID

• RUNTIME PERFORMANCE
• one dual-CPU PC _at_ 3GHz
• one PT with Athena/TileMon
• now 30 histos with 100 bins
• in verbose debug mode
• rate is 50 Hz (50 evt/s)

Status Conclusions

• current situation with SW versions
• Problem
• ReadOut switched to tdaq-01-04-00 (new eformat
  !!)
• no HLT release / SW image ready for corresponding
• Athena (10.0.7/11.0.0) yet !!
• Status
• currently develop histos in offline (emu) mode
  (file_sampler)
• expect new HLT SW in 2 weeks then can try
  Online
• (hopefully before October 26)
• then also use new versions of EF-mon components !
  (PTIO)
• then also integrate with TDAQ/EB DataFlow
  (preseries _at_ P1)
• Mismatch between versions
• Brings confusion in code development
• Blocks integration with online readout
  pre-series cluster _at_ P1 !!!
• To avoid mismatch in the future
• Advise to Keep synchronized with HLT SW Image,
  not just TDAQ versions
• Advise to Plan develop code according to HLT SW
  Image schedule
