PR description:

Backport to 14_0_X of

Details:

  • Change ScoutingNano event content from #45820 since the changes to add ScoutingMuonNoVtx and ScoutingMuonVtx from #44970 are also propagated to #45820.
  • Add run3_scouting_nanoAOD_post2023 to Era_Run3_2024.
  • Add T0 processing scenarios for processing HLTSCOUT datatier as inputhltScouting, hltScoutingEra_Run3_2024 from #44970.
  • Add hltScoutingEra_Run3_2024 scenario to unit test run_CfgTest_8.sh and add new unit test run_CfgTest_13.sh specific for hltScouting scenarios from #44970.
  • Add workflow 2500.6 to relval_nano. Since #45419 won't be backported to 14_0_X, only necessary information for workflow ScoutingNANOdata140Xrun3 is added. The input file and lumisection range are the same as in #45419. The names are the same as in #45419 for NANO_data14.0, ScoutingPFRun32024RAW14.0, ScoutingNANOdata140Xrun3, except NANO_dataRun3ScoutingPF14.0 which corresponds to scoutingNANO_data14.0 in #45419. This is to keep a convention used in 14_0_X release.

Event size is measured with relval_nano matrix. These are default ScoutingNano with only scouting objects and without standard offline objects and without gen info (for mc).

  • 0.88 kB/event (2500.5 ScoutingNANOdata13X)
  • 2.07 kB/event (2500.51 ScoutingNANOmc13X)
  • 1.14 kB/event (2500.6 ScoutingNANOdata140Xrun3)

Workflow 2500.5 is similar to 2500.131 and 2500.6 is similar to 2500.237 after #45419, so measured event sizes are the same. 2500.51 uses TTBarMINIAOD13.3 while 2500.227 after #45419 uses TTbarMINIAOD14.0, so measured event sizes are slightly different.

Size reports (root files used and size report html files) can be found in 09.07.2024_ScoutingNano_size_reports.

Note: another related PR is #45949 which is a backport of #45820 to 14_1_X to ensure that the event content changes are consistent in subsequent releases across 14_0_X, 14_1_X, and 14_2_X.

PR validation:

when running on el9_amd64_gcc12, pass all unit tests from scram b runtests except:

This unit test failure on el9_amd64_gcc12 seems to relate to #45614.

Next following tests are all done on el8_amd64_gcc12.

Pass all tests from runTheMatrix.py -l limited -i all --ibeos

Other tests:

  • RunPromptReco.py example. The outputs look reasonable:
python3 Configuration/DataProcessing/test/RunPromptReco.py --scenario=hltScoutingEra_Run3_2024 \
--global-tag=140X_dataRun3_Prompt_v4 --nanoaod --nanoFlavours=@Scout --lfn=fileIN.root

  • runTheMatrix.py --ibeos -l 2500.6 (added ScoutingNano workflow) passes and the output nano file looks reasonable
  • cmsDriver.py example. The output looks reasonable:
cmsDriver.py step2 -s NANO:@Scout --process NANO \
--data --eventcontent NANOAOD --datatier NANOAOD -n 1000 \
--era Run3_2024 --conditions 140X_dataRun3_Prompt_v4 --filein fileIN.root

Hi @hqucms,

From TestConfigDP_13/testing.log, the problem is Permission denied. This is a new unittest for hltScoutingEra_Run3_2024. This also happened when I was testing before I opened this PR. The file's permission needs to be set as executable, e.g. with chmod 755 . Checking this again, I didn't have 755 mode pushed to the branch. I'm pushing this now, sorry.
