sPHENIX tracking discussion

["Huang, Jin" <jhuang AT bnl.gov>]

Hi Everyone

 

I think this is probably caused by my PR https://github.com/sPHENIX-Collaboration/coresoftware/pull/1490 , in an unintended consequence of resolving another rare crash. Unfortunately, it slip the crack between QA and evaluator ntuple maker during the CI checks.

 

Let me try submit a quick fix from macro side (build truth table before evaluator) with a better fix later on coresoftware side (allow truth table indicate whether it has been processed)

 

Cheers

 

Jin

I am running the SvtxEvaluator right now to see if my magfield changes and the super low memory profiles are real and I do get matches.

 

The last few jenkins reports I got also have track matches in. They use the evaluator machinery as well.

Hi Tony,

 

If you take the SvtxTruthRecoTableEval module out of the evaluation in the G4_Tracking macro, do you get matches? There were some changes made to this module the other day and I wonder if that broke the matching somehow.

Hi Christof,

 

I am running the full sim + reco chain, and the clusterhitassoc is present on the node tree.

 

Tony.

Hi Tony, 

 

another possibility is that the clusterhitassoc container isn't present.

For data reco we dont need it and we can drop it. 

For MC matching we still need to keep it around. 

 

cheers

Hi Tony,

 

Argh. This might be a bug introduced by https://github.com/sPHENIX-Collaboration/coresoftware/pull/1484

I had to modify the evaluators to rely on the cluster keys stored in the container and not in the cluster. Doing so, I might have messed up something ...

Not being very familiar to the SvtxEvaluator I could not test it extensively.

If you send me a macro that can reproduce the problem, I can compare between before and after the PR got merged and debug ...

When I run the repository code with updated macros, I see reconstructed tracks and truth tracks in their respective evaluator ntuples, but the matching between them seems to not work. The ntp_track ntuple does not have any truth matching info, and ntp_gtrack does not have any reconstructed track matching info. Do others see this?

 

Thanks

Tony
