Hi @fratnikov , do we know the impact of the ressources (memory , timing) at high PU ? I'm worried because for HGCal we are trying to reduce the reco step , and also we are just about to send big digi-reco prodcution for Shaslik, so i'm worried that this is inducing resosurces while we are already at the limit (or even already above..) .

@boudoul: we currently produce 35 Jet collections in RECO (see below),
22 PFJets, 5 GenJets, 6 CaloJets, 2 BasicJets. However neither of them
is considered as reference for Jet/MET performance studies, so people re-reconstruct
AK4 jets privately to get reference objects and work from them.

Very conservative estimation is that adding 3 more Jet collections to 35 already available
won't increase total jet reconstruction footprint by more than 10%.
This is PU invariant estimation, and total jet reconstruction is likely not the primary
resource waster.

However, if resources is big an issue requiring action, we can safely drop all jet collections
except AK5 and KT6, as other jets are dedicated for higher level analyses which are
not feasible until basic Jet reconstruction i.e. AK4 jets are established.

indeed, there are memory problems..

perhaps removing some of the unneeded jets would benefit everyone

@davidlange6 If you talk about RAM shortage, then reducing number of jet collections won't help: jet reconstruction memory consumption is driven by number of input objects, which is pretty the same for all used jet algorithms of given flavor. So I expect no difference in peak RAM consumption between running one jet algorithm and running many of them sequentially.
