Instructions to update the configuration and run with dunedaq v5 line

Area setup

First of all you need a v5 area. To do this follow the instructions in the daqconf wiki, for example fddaq-v5.3.2.

Locally, in the top area, you also need the base configuration repository. Please note that the repo on gitlab are only accessible via ssh key, so please register one in the CERN gitlab. I recommend you also set in your area a .netrc file as in the np04daq home, remember to change login to your CERN username. After that you can simply

git clone ssh://git@gitlab.cern.ch:7999/dune-daq/online/ehn1-daqconfigs.git

Or alternatively

cpm-setup -b fddaq-v5.3.2 ehn1-daqconfigs

The first one is a direct clone, while the second sets up the configuration repo to do some more advance operation, so the default branches might be a little strange. Further domentation on the various cpm-* commands can be found in the runconftools documentation. The second only works if you have setup the .netrc file correctly. To conclude, just

source ehn1-daqconfigs/setup_db_path.sh

Update the CTB configuration

The ehn1-daqconfigs contains already a valid configuration for the CTB. Due to the implementation of HLTs and LLTs as confmodel::resource, it's best if any branch of ehn1-daqconfigs contains only one version of each. So, as CTB experts the only thing you should do is to update the value of the objects already created in ehn1-daqconfigs.

In order to do so, there is a script called update_ctb_settings. Typical usage is:

update_ctb_settings ehn1-daqconfigs/sessions/np02-session.data.xml <your_json_file>

This will do the following:

It will change the value of every objects in the configuration related to the CTB according to the the json file you provide
It will enable/disable HLTs and LLTs according to your configuration Please keep in mind that HLTs can also be enabled/disabled via the shifter interface (see dedicated section).

Once you are happy with the changes, you can commit and push the changes on a branch on ehn1-daqconfigs and open a Merge request toward the dedicate branch.

Run the CTB configuration

in order to run, start using the shifter interface in local mode:

runconf-shifter-ui -l -d ehn1-daqconfigs

From the inerface select which components you need, select which HLTs you want to enable and click create. The output of the shifter interface will tell you how to run.
