Modification of cone based tau algorithm to furbish it as fallback solution for the HLT for upcoming data taking #18429

roger-wolf · 2017-04-20T22:49:30Z

Dear colleagues,

this is a pull request by @mbluj that contains modifications of the cone based tau reconstruction algorithm as used for the HLT to make it fit for upcoming data taking periods, as fallback in case that the planned HPS-port to the HLT won't be ready in time. I'm citing Michal's comments (*) and refer to him for further questions.

Cheers,
Roger

(*)
This PR is to modify the Cone-based tau builder (used at HLT) to fill some additional data members of produced PFTau not filled so far:

Size of signal cone (cone for PiZeros used);
Pt carried by signal PiZeros outside of the signal cone; it is important shape variable supporting isolation in rejecting jet->tau fakes;
Charge, pdgId, tau decay mode hypothesis.

The changes do not modify current HLT work-flow (the builder is used only at HLT), but provides new features (cf. 2) allowing better jet->tau fake rejection during 2017 data-taking.

This is PR to 91X on top of changes proposed for tau vertex association (cf. #18243), a separate PR for 90X will follow shortly.

so this looks to be just a more inefficient version of existsAs... Could this not be replaced by a fillDescriptions instead?

@davidlange6 Yes, in principle fillDescriptions will solve this and similar issues caused by the fact that HLT configuration is dumped from ConfDB which knows on new parameters only when a new release is parsed into it. The thing is that the tau reco code uses quite heavily plugin factories which, at least in my understanding, are quite incompatible with the fillDescriptions mechanism. So mitigation from python cfi files to the fillDescriptions mechanism means rewriting tau code which is a big effort.

davidlange6 · 2017-05-02T10:16:07Z

I'm not sure what prevents the plugins to use fillDescriptions - but in the meanwhile, i think I would then suggest the bad old fashioned existsAs as to avoid yet another loop over all producers in the HLT. but maybe i don't know all the constraints.

Maybe it is my ignorance, but tau reco has a nested structure with one plugin calling other ones. Depending on configuration the set of nested plugins can be different, so I do not think that there is a way of sensible configuration of them with fillDescriptions.

- but in the meanwhile, i think I would then suggest the bad old fashioned existsAs as to avoid yet another loop over all producers in the HLT. but maybe i don't know all the constraints.

It is what we agree, the existsAs constructions should be removed. But, this particular customization (customiseFor18429) is not about this; it just adds missing tracked parameters to HLT configuration as the configuration does not know nothing about them. It is as it the HLT configuration dumped from ConfDB where configuration templates come from an older release. The customization is temporary and will disappear when configuration in HLT ConfDB are refreshed with newer release. I hope, that this time I was able to explain it more clear than previously.

any idea what functionality is actually missing? Some "CMSSW" (eg, framework) feature or just that developers need to do something? I would have thought that any plugin could define a static function that gets called by the module level fillDescriptions to hierarchically define a pset. I've not thought about issues such as dependencies however. Has anyone tried an implementation that didn't work out?

@davidlange6 See e.g. #12517 (comment), and especially https://hypernews.cern.ch/HyperNews/CMS/get/edmFramework/3446/1.html.

(personally I've given up the hope in favour of moving helper plugins to ED/ESProducts, depending if they need edm::Event or not, even if this approach is rather laborious)

this particular customization (customiseFor18429) is not about this; it

to be clear I said the opposite - we removed an ugly, but fast/simple construct (existsas) in favor of an ugly and slow construct (for modules in hlt loop....).

The "ugly, but fast/simple construct (existsas)" happened at runtime, and was not tracked in the provenance. The "ugly and slow construct (for modules in hlt loop....)" can be made to happen only once by dumping the configuration (which I think crab and other tools do), and not at all once the new configuration is parsed and made available. In addition the provenance sees the expanded configuration with all the parameters. .A
