Reduce minYsizeB1 and minYsizeB2 CA cuts for Phase1 #47271

bdanzi · 2025-02-05T15:21:14Z

PR description:

The PR aims to minimize the Cluster Size Cuts for the Phase 1 geometry on the B1 and B2 layers, specifically when considering B1-FPIX and B2-FPIX doublets. These doublets serve as the initial inputs for the CA. The changes have been tested on top of the Phase 1 CA-tuned parameters.

This adjustment results in about 5% relative efficiency gain in hltIter0PFlowTrackSelectionHighPurity and a 3% gain in hltMerged. Additionally, it reduces the reliance on the Doublet Recovery iteration, leading to a corresponding decrease in efficiency for hltDoubletRecoveryPFlowTrackSelectionHighPurity. Track resolution shows a small improvement as a function of pT.

Instructions on how to run

Tested in CMSSW_15_0_0_pre2 at HLT step.

Generate the .cff file on lxplus and place it inside HLTrigger/Configuration/python by running:

hltGetConfiguration /dev/CMSSW_14_2_0/GRun/V10 --globaltag 140X_mcRun3_2024_realistic_EOR3_TkDPGv7 --mc --unprescale --output minimal --max-events 500 --input file:input_file.root --cff --eras Run3_2024 --l1-emulator uGT --l1 L1Menu_Collisions2024_v1_3_0_xml --paths MC_ReducedIterativeTracking_v22 > hltMC_default_onlyTracking.py

-    static constexpr int minYsizeB2 = 28;
+    static constexpr int minYsizeB1 = 1;
+    static constexpr int minYsizeB2 = 1;


could these parameters be exposed as configurable parameters instead of hardcoded?
I guess this would ease the checks to be asked to various stakeholders.

Should be done in ef9d50d

@cms-sw/orp-l2, it would be great to get this PR into CMSSW_15_0_0 for 2025 HLT development purposes.
As it is, it does change (HLT) physics, could it enter in pre3 still?
Otherwise I guess it would be more acceptable if it would just make the parameters configurable, followed by a change in the HLT menu configuration?

Let's try to get it merged tomorrow, that will be fine for pre3

excellent, thanks.

It looks like for some reason the commands to enable gpu and test are not being received correctly?

It now seems to have worked, although tests are still pending - I see a similar behavior in other PRs

As it was a general issue, I would have hoped it would be taken into account by @cms-sw/orp-l2, especially after the comment by @mandrenguyen, as this would have been fully tested and signed if it wasn't for the issue described above by @smuzaffar.
But sure, we will open a backport at this point.

We did take the request into account, as you just noted. We decided, however, not to further the delay the pre-release which was scheduled for Tuesday. The final 15_0_0 will not be cut until the 24th. This will be included.

The final 15_0_0 will not be cut until the 24th. This will be included.

Thanks. As far as I can tell the main inconvenience is that if this would have entered in pre3 we could have profited of the regular HLT release validation (one pre-release earlier).
