Producing microDSTs standalone
Getting the relevant packages
SetupProject DaVinci v22r0p2 --build-env
SetupProject DaVinci v22r0p2
getpack Phys/DaVinci v22r0p2
getpack PhysSel/Ccbar
getpack Ex/MicroDSTExample
cd ${User_release_area}/DaVinci_v22r0p2/Phys/DaVinci_v22r0p2/Phys/DaVinci/cmt
gmake
cd ${User_release_area}/DaVinci_v22r0p2/Ex/MicroDSTExample/cmt
gmake
cd ${User_release_area}/DaVinci_v22r0p2/PhysSel/Ccbar/cmt
gmake
Making the microDST
Do
cd ${User_release_area}/DaVinci_v22r0p2/Ex/MicroDSTExample/job
gaudirun.py ../options/TestMicroDSTMake.py
ls -ltr
You should now see a .dst file in this directory which has just been created. For this standalone production of microDSTs take care that the following lines in the file ${User_release_area}/DaVinci_v22r0p2/Ex/MicroDSTExample/options/TestMicroDSTMake.py:
#importOptions( "$MICRODSTEXAMPLEROOT/options/JpsiPhiDataLFN.py") importOptions( "$MICRODSTEXAMPLEROOT/options/JpsiPhiDataPFN.py")
This takes care of using the PFN (physical file name) this time instead of the LFN (logical file name), which we will use later working with the Grid.
Producing microDSTs on the Grid
Become a gRidder
First obtain a Grid Certificate from the Dutch Grid CA.
When you've done this, become a member of the LHCb VO by following this link.
To use the Grid from lxplus you need to copy your certificate to lxplus. You do this by copying the entire .globus directory to your home on lxplus.
Configure Ganga
To setup Ganga do
GangaEnv
Now we still have to configure the file ${User_release_area}/DaVinci_v22r0p2/Ex/MicroDSTExample/job/MicroDST_Ganga.py
First set the correct DaVinci version in this line:
dv = DaVinci( version = 'v22r0p2' )
Now choose the desired backend. To run jobs on the Grid uncomment
#j.backend = Dirac()
When all options are set correctly, submit the jobs:
WHAT ABOUT THE LFN/PFN issue at this point?
ganga MicroDST_Ganga.py
If you work on a 64-bit machine (which you do when logged in on lxplus) you get an error message saying that only slc4_ia32_gcc34 is allowed on the Grid. So you should type
setenv CMTCONFIG slc4_ia32_gcc34
- job.outputsandbox = [] # let the uDSTs go to 'dataoutput', so Grid SE (Storage Element)
Copying microDSTs from Grid to Sara
Stageing the Sara microDSTs on Stoomboot
Reading microDSTs
microDSTReadingExample.py
of maak wat nieuws in Bender
Analysis
P2VV
getpack PhysFit/P2VV getpack PhysFit/P2VVPython
and use the RooFit based fit package
