Goals

Implement final changes in RD modules for 2025 datataking including fixes, rate+bandwidth reduction, and additional lines.

Contributing

DO NOT PUSH directly to the branch of this MR (rd-devel-march25) unless you are instructed to do so by the coordinators. Additions for the start of 2025 data-taking should happen in independent branches, one per topology. If you want to modify anything, please check first whether there are other relevant MRs with the RD label that implement changes in you modules (i.e. work on a similar topology), and comment on them instead.

The deadline to undraft merge requests targetting this branch is 21/03/2025. At this point the merge requests must be complete and the impact on bandwidth and rate must be provided.

All the additions need to be tested locally following these instructions, including:

  • Impact on the bandwidth and rate: if including new lines, these must be well justified (i.e. the physics case must not be already covered by other existing lines) and have rates and bandwidths below 100 Hz and 10 MB/s, respectively. This must be tested on real data.
  • Impact on the throughput: comparing the time with the execution of rd-devel-march25 with no extra modifications.
  • (optional) Determine efficiencies: if there is simulation already available, it will be interesting to know the efficiencies so we ensure that there is no bug in the selections.

Do not rebase or force-push to this branch since this might lead to losses on the changes

The source branch of this merge request should work on LCG106c with all other projects on master except ParamFiles which should be on rd-devel. If this doesn't work, it definitely works with the commits below. You may need to make purge before you can successfully make (please let us know if you have problems)
