Trigger Exercise for the CMSDAS @ LPC: Setup

Setup the work area

The following instructions assume you are using Bash. To switch to Bash, use bash --login.

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

cd public/
mkdir HATS2024 
cd HATS2024
cmssw-el7
cmsrel CMSSW_10_6_31_patch1
cd CMSSW_10_6_31_patch1/src
cmsenv
git clone -b 2024 https://github.com/FNALLPC/LPCTriggerHATS.git
scram b -j 4

Alternatively if workig on Fermilab LPC:

cd nobackup/
mkdir HATS2024 
cd HATS2024
cmssw-el7 -p --bind `readlink $HOME` --bind `readlink -f ${HOME}/nobackup/` --bind /uscms_data --bind /cvmfs -- /bin/bash -l
cmsrel CMSSW_10_6_31_patch1
cd CMSSW_10_6_31_patch1/src
cmsenv
git clone -b 2024 https://github.com/FNALLPC/LPCTriggerHATS.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-el9.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
    [I 08:22:45.871 NotebookApp] 0 active kernels 
    [I 08:22:45.871 NotebookApp] The Jupyter Notebook is running at: http://localhost:8888/?token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    [I 08:22:45.871 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
    [C 08:22:45.873 NotebookApp] 
        
        Copy/paste this URL into your browser when you connect for the first time,
        to login with a token:
            http://localhost:8888/?token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
