Some notes on going forward

  • ​
  • Communications of the software group with working group need to be improved, in both directions
    • Liaison list
  • ​
  • Continuous integration/development is important
    • and in place / growing
  • ​
  • Thomas brought up that sans second detector we're in a rare situation, are there

plans to focus specifically on items of self-control like blinding?

​

Reconstruction is a hot topic - still having unit interface issues etc., crucial to fix for upcoming Ecal review

Simulation Campaign notes

  • ​
  • Close to 1M jobs done
    • mostly on the OSG (10s of thousands of slots available as opposed to 2k at the labs)
    • <1% failure rate, identified problematic sites to avoid
    • current requirements add up to a million core-hours, 114 core-years
    • Barbara offers NERSC
    • Some S3 problems around Thanksgiving, related to key SDCC departure
  • ​

Next campaign aimed for end of March

​

Future: PanDA, Rucio, …

Others

  • ​
  • Chris Dilks' original SIDIS analysis framework is adopted by more and more PWGS, becoming the de-facto standard
    • Support ePIC, ECCE, ATHENA, Delphes
    • Data retrieval automation
    • Kinematics Reconstruction, Q2 weighting
    • Continuous Integration
  • ​

AI/ML is touched upon in many ways and many works from design optimization to improved kinematic reconstruction to analysis

​

Many MCEGs still needed, �many still don't have native HepMC3 support
