NanoScouting in Prompt

[silviodonato]

Dear Tier-0 experts, from the Scouting group we would like to start having the NanoScouting production in Prompt, possibly before the end of the pp collision data taking (16/10/2024). All the code is available in IB and it will be included in 14_2_0_pre1 (#44970) and in one of the upcoming 14_0_X release (#45950 )

Describe the new feature you would like T0 to implement.

• What are the goals of the new feature?
  • Provide the NanoScouting automatically during the data taking as soon as PromptReco is ready.
• Which systems will it affect?
  • Tier-0 and storage of offline data

What are the changes and technical challenges?

• The request is to run the nanoSequence defined in PhysicsTools/NanoAOD/python/custom_run3scouting_cff.py at Tier-0. A working example can be provided using cmsDriver.py [1]. Note that this sequence is tested in IB through workflow 2500.237. The input dataformat is HLTSCOUT and specifically the scouting dataset, ie. /ScoutingPFRun3/Run2024G-v1/HLTSCOUT. The output dataset should be in the NANO format, ie. the output dataset should be something like /ScoutingPFRun3/Run2024G-v1/NANO. Please note that this is a production of NANO directly from HLTSCOUT, as it is not possible to run the standard offline reconstruction (RECO step) in scouting dataset.

Describe the implementation timeline of the new feature and relevance for the CMS data taking.

• perform a test with 14_2_0_pre1 as soon as the release will be available (#44970)
• deploy it online as soon as a 14_0_X release containing #45950 is available (hopefully before 16/10/2024)

Additional information This has been already discussed at the DeepDive on NanoAOD, with PPD (@malbouis @vlimant ) and TSG (@missirol @mtosi). @elfontan

FYI: https://github.com/cms-sw/cmssw/pull/45950 has been just merged, so this request can be implemented directly on the next 14_0_X release (ie. CMSSW_14_0_15_patch2 or CMSSW_14_0_16)

Hi @silviodonato, all

CMSSW_14_0_16 was just released with https://github.com/cms-sw/cmssw/pull/45950. Release note

Additionally, scenario hltScoutingEra_Run3_2024 is included in the PR as well. This is designed for producing ScoutingNano from HLTSCOUT datatier (ScoutingPFRun3 dataset).

Some testing with RunPromptReco.py was also performed in PR:
