  1. Calorimeter commissioning meeting – 05 april 2007 Software installation for commissioning tests Olivier Deschamps

  2. Software installation • Account on online system and Crack available since monday • on farm pit : lbgw.cern.ch (gateway) • on Crack : lbcrack2li1.cern.ch • Crack node accessible since yesterday : crack2nodeX • please check your account/passwd and report to Suman in case of problem • Software installation on Crack • LHCb software pre-installed (/lhcb/sw/slc4/lhcb/) • essentially the ONLINE project v3r1 and dependency (LHCB v22r2) • ORWELL package and dependencies (condDB) uploaded yesterday (thanks Markus) • Install and compile in my home directory all packages we will/may need to modify • Calib/Orwell << Calo Calibration application • Calib/CaloCalib << Calo Calibration algorithm • Calo/CaloDAQ << TELL1 data decoding • Online/OnlineTasks << EventBuilder • Online/GaudiOnline << EventBuilder • Det/SQLDDDB << condDB • some scripts to setup and launch the eventBuilder also installed

  3. Software installation • Software installation on Crack (cont’) • No real difficulties encountered but few minor issues • quickly fixed by the Online group (thanks to Niko, Radu, Suman, Markus) • standard remote installation of Orwell project and dependencies (condDB) • ‘clock skew’ error when compiling • Account error on crack2nodeX • lbcrack2li1 not mounted on crack2nodex • Pending issues : • Difficulties to set-up CVS • would be useful to commit/checkout modification in the codes • « QT module » not available • required for Graphical Interface to condDB • needed to update the cabling scheme used for the test (FE->TELL1) • indirect solution exists : change DB on lxplus, ftp on crack • Expected to be fixed today but no show-stopper anyway  Software essentially in place on the CRack

  4. Pre-commissioning test in Bdg 156 • To do during hardware installation : • Fill condDB with the actual cabling scheme used for the test • Set-up the eventBuilder chain (Tell1 IPs, …) • Tests to be done : • Acquire TELL1 output and store data on disk  ‘Offline’ analysis • a) MEP = 1 single event  write MDF file • b) MEP = bunch of consecutive bunch-crossing events  write Root file (see below) • 2) Online Orwell run on the incoming data and store histograms output on disk • Consecutive bunch-crossings • The eventBuilder can be set-up to store consecutive bunch-X in a single Gaudi-Event • set-up ODIN and TELL1 to produce MEP from a bunch of consecutive BCID events • Special EventBuilder decode MEP and populate several rawEvent in TES • at different locations : Event/Prev1/DAQ/rawEvent ; Event/Next1/DAQ/rawEvent • The Gaudi-Event can be stored as root file using the DSTwriter as used in Boole

  5. Pre-commissioning test in Bdg 156 • Consecutive bunch-crossings (cont’) • With the current release of Orwell algorithm the consecutive events can only • be analysed as ‘independant’ events •  run Orwell independantly on the various consecutive RawEvents • i.e. cannot correlate the consecutive signals, e.g. cannot produce the histogram • of the ADC for the Prev1 bunch-X in a given channel when signal is detected • in the same channel at T0. •  Can only have histo for Prev1 independantly of T0. • Need to modify CaloCalib algorithms to handle simultaneously consecutive Bunch-X.

  6. Software installation in the farm pit • Software installation on farm node • No yet started due to yesterday power cut of the online system • Essentially the same steps as in the Crack • No difficulties expected • Running software to be installed in the /group/calo/ directory • Software installation • normally should go via the standard installation procedure • releasing/tagging/installing (request to Marco C. then Joel) • quite heavy during test/commissioning period • Need CVS to be in place for fast modification/re-installation • Storage system • Online group testing the high-speed filewriting • should be available for storing Tell1 data/histogram for our tests • Temporary solution for next week if the not fully ready • Need to discuss the test schedule with Radu to set-up the storage chain • Histogram publishing via DIM DNS • Discussion with Monitoring group ongoing • Test to be scheduled but probably difficult for this week

  7. Summary • Software essentially in place on Crack for pre-commissioning • few minor issues to be fixed today • Installation in the farm will follow this week • What we’ll learn (hopefully) with pre-commissioning : • get more experience with the full DAQ chain & online set-up • Check/debug hardware/software consistency • Tell1 data format, condDB description of the cabling scheme, … • treatment of consecutive bunch-crossings • improvement to be foreseen in the Calibration algorithm • Histogramming/Monitoring system
