G2.2: All core components of the Analysis Systems pipeline fully support distributed analysis

[matthewfeickert]

• Overview of blocking and non-blocking issues

Core tools

• Uproot
  • uproot.dask
• Awkward
  • dask-awkward
• Boost-histogram / Hist
  • dask-histogram
  • hist.dask
• Vector
  • Support for dask-awkward arrays scikit-hep/vector#301
• Coffea
  • Use scikit-hep vector to as the backend for vector math in nanoevents scikit-hep/coffea#992 (non-blocking)
  • Change CaloCalTopoClusters to egammaClusters for PHYSLITE scikit-hep/coffea#975
  • PHYSLITE schema and inconsistent amounts of data being read for the same task scikit-hep/coffea#1073
  • PHYSLITE schema and EnergyPerSampling branch scikit-hep/coffea#1074
  • Size of array is less than size of form with PHYSLITE schema scikit-hep/coffea#1083

Blocking

• Uproot
  • Being able to read data from data and simulation PHYSLITE files
    • Can't read a branch II scikit-hep/uproot5#1138
    • Add PHYSLITE file (max of 1 MB) to scikit-hep-testdata for uproot testing.
