Trigger short exercise CMS DAS @ Fermilab LPC (January 9-13, 2023)

See DAS twiki for detailed instructions: https://twiki.cern.ch/twiki/bin/viewauth/CMS/SWGuideCMSDataAnalysisSchoolLPC2023TriggerExercise

Setup the work area

Set up the CMSSW environment and clone the repository from github for the trigger exercise:

source /cvmfs/cms.cern.ch/cmsset_default.csh
setenv SCRAM_ARCH slc7_amd64_gcc700
cd nobackup/
cmsrel CMSSW_10_6_31_patch1
cd CMSSW_10_6_31_patch1/src
cmsenv
git clone https://github.com/elfontan/ShortExerciseTrigger2023.git
scram b -j 4

Jupyter noteboooks

If you want to use Jupyter notebooks on cmslpc, please review the content of your ~/.ssh/config file on your system by executing:

cat ~/.ssh/config

In case the file does already contain the following lines, add:

Host cmslpc*.fnal.gov
    StrictHostKeyChecking no
    UserKnownHostsFile /dev/null

When you log into cmslpc, add a -L option to your ssh command:

ssh -L localhost:8888:localhost:8888 <YOUR USERNAME>@cmslpc-sl7.fnal.gov

Then you can make your area as detailed above and start Jupyter with this command:

jupyter notebook --no-browser --port=8888 --ip 127.0.0.1

After a pause (while cmslpc loads the necessary libraries for the first time) you should see a message like the following:

[I 08:22:45.871 NotebookApp] Serving notebooks from local directory: /uscms_data/d2/pivarski/CMSSW_9_0_0_pre6/src
