Storage requirements of QM02 production (ONE pass/version) can we continue with “business as usual?” II
The “big four” PWGs (EbyE, Strangness, Spectra, HBT) do not analyze directly STAR DSTs (primarily for speed reasons), using instead ntuple/tree-based mDSTs with similar event/track cuts
HBT mDST ~ 23 x smaller than STAR DST (event.root files w/no hits)
? require 9TB/23 ~ 400 GB for single QM02 production
? “big four” could almost keep their QM02 mDSTs on 2x800 GB PWG disks
(but would need some more, to keep 130 GeV data as well)
But again, let’s say yes, barely, the big four could continue as usual
