September 2019 Offline Leads Meeting Notes

The September 2019 LArSoft Offline Leads status update was handled via email and a google document.

LArSoft – Erica Snider

While we knew that Lynn Garren was retiring the end of January, 2020, we recently learned that Paul Russo is leaving the middle of September. Paul was providing customer support on LArSoft tickets and expertise on multi-threading for LArSoft. We do not yet know what the replacement strategy is. 

Due to the changes in available resources, the project needs to shift some responsibilities to the experiments, particularly in the area of code and release management. 

  • MacOS support – LArSoft support for Mac builds is ending. Could either find someone else to support those builds, or have MacOS developers  use SLF containers. (Note that support for those containers will not come from the SciSoft team.)
  • GitHub Migration – Need to identify people in experiments for manager roles defined in the pull request workflow. See slides from Patrick Gartung’s presentation Migration of LArSoft repos to GitHub. We will hold additional discussions and provide opportunities for beta testing prior to the migration to GitHub and deployment of the pull request system.

The project has begun the annual process of gathering input from the experiments to inform the 2020 LArSoft work plan. We have met with all the experiments. An initial draft work plan will be discussed at the October Offline Leads meeting.

DUNE – Andrew John Norman, Heidi Schellman, Tingjun Yang, Michael Kirby

ProtoDUNE has started the second production campaign using larsoft/dunetpc v08_27_01. A ProtoDUNE-SP simulation task force is formed to improve detector simulation. The goal is to incorporate the refactorized larg4 and wirecell simulation. DUNE is in the process of transitioning to use tensorflow v1_12_0b with the help of larsoft team. More details in #22504.
