RPCTriggerFilter

Looking into the RPCTriggerFilter code (inside DQMOffline/Muon)

• From data, the filter creates the following table:

• Those flags are then used with some user input variables to evaluate the final decision:

• Running over /Cosmics/Commissioning08_CRUZET4_V4P_multiCosmicMuon_v1/RECO block id 6ec52b91-f551-4dc2-8ee3-87c99db3f3bb

• RPCTriggerFilter.log: Log file for a run with 100 events
• checkdata.out: Debug data from the same 100 events and dataset

• /Cosmics/BeamCommissioning08-PromptReco-v1/RECO ( contians 220 file(s) with run 62815 ) --- runs quite stable in memory usage (for 40000)

• RPCTriggerFilter_Short.log: Log file for a run with 40000 events (two files were opened)

• cruzet4-datsets.tgz: list of files used for the testing of RPCTriggerFilter

Logic Implementation

• The way logic is implemented in the code is via an Object Factory: LogicFactory and handled from the main process using a LogicTool

• Logics derive from 2 interfaces: RBCLogic and TTULogic: RBCLogic describing the RBC boards logic and TTULogic describing the TTU logic.

• Once you have an implementation of this type of logic, you have to introduce it in the factory (this procedure is not pretty at the moment):

• • declare and implement a createYourLogic( ) function in "LogicImp.h" and "LogicImp.cc" files. This function returns a new object of your logic type.

• • Now open the Tool "LogicTool.h" and introduce your logic in the factory container and give it a key to access it. That should be all! You should be able to create your tool and initialize it with the selected logic.

Simulation of Cosmic muons

• In CMSSW 2_1_9: Interface to cosmic muon generator: GeneratorInterface CosmicMuonGenerator
• Simulation done using the 2_1_10: follow instructions found in here

Latest progress

• RPCTechTrigg emulation - class collaboration:
  

• Summary:
  • Integration into CMSSW almost completed
  • At the moment everything is driven by a single Analyzer called RPCTechnicalTrigger
  • Two main objects hold the main structure: RBCEmulator and RPCTTU (better name? TTUEmulator?)
  • At the moment, the tests can be done from reading a single ascii file containing all the signals as if they were taken from the LBBox ; in addition it also can read RPC Digis
  • Logic based on WheelMap and TrackingAlgo

Note: Test documenting code in TWiki:

for i in range(100):
zipped = zip(*list_of_lists)

for( int i = 0; i < 10; ++i ) {
   zipped = zip(*list_of_lists);}

Implementing access to the condition objects in cmssw to access the hardware configuration in the TTU Emulator:

Following the instructions from https://twiki.cern.ch/twiki/bin/view/CMS/SWGuideCondDB

• https://twiki.cern.ch/twiki/bin/view/CMS/SWGuideCondSystemLayout
  • Compilation after the whole procedure produces the wanted plugins:

XDAQ application

Learning how to use it. The main project page is at XDAQ home page

• Downloaded the source code:
  • Download page: http://sourceforge.net/project/showfiles.php?group_id=23237
  • I put all three tgz files under /opt/CMS/XDAQ/tarfiles ( coretools_G_V03_14_00.tgz powerpack_G_V01_13_00.tgz worksuite_G_V01_13_00.tgz )
  • When you untar all files, everything is put under /opt/CMS/XDAQ/TriDAS

• Installation procedures

----------------------------------------------------------------------

Libraries have been installed in:
   /opt/CMS/XDAQ/TriDAS/daq/../x86_RedHat/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

However I got this error message:

Calling make all in directory /opt/CMS/XDAQ/TriDAS/daq/../daq/extern/tinyproxy/.loop using install
make -C /opt/CMS/XDAQ/TriDAS/daq/../daq/extern/tinyproxy/ -f Makefile _installall
