September 2020 Offline Leads Meeting Notes

LArSoft – Erica Snider

Every year we query the experiments about their plans for the upcoming year in preparation for the LArSoft work plan. These meetings between each experiment and Erica and Katherine will begin in September and continue into October with a draft 2021 LArSoft work plan being available in November and presented at the December Steering Group meeting.  We expect that the major focus will continue to be modernizing the code to be multi-threaded, or to run in multi-threaded environments. We will also continue to facilitate work toward using LArSoft on HPC resources and platforms as they become available. Expect that interest in using deep learning for LAr reconstruction will continue to grow. LArSoft will want to facilitate using these methodologies within art / LArSoft jobs. 

Pixel LArTPC readouts. 

  • Considering geometry service overhaul to accommodate pixels, where a complete re-factoring is indicated. While there, better factorize channel mapping initialization to simplify stand-alone construction and minimize dependencies.

Decoupling generators from LArSoft:  the key to solving this problem is to address how to initialize the geometry information needed by the generator without creating a compile-time dependence on a particular version of LArSoft.

Work continues on transitioning from the old to new LArG4, with good progress in protoDUNE simulation now being transferred to the Far Detector. We continue to take advantage of close collaboration with SBND to adopt improvements in photon simulation. At the most recent DUNE collaboration meeting, we held our first joint meeting between ND and FD Sim/Reco groups to start building towards more cohesive software across both detectors.

SBND – Andrzej Szelc

SBND is working towards preparing for a small MC production bound to happen in October in preparation for a larger-scale production in the fall. One of the things that is being worked on is an update/tweaking to the semi-analytic model of light simulation (Patrick Green). In parallel, there is an ongoing effort to get SBND running on the factorized version of LArG4. Preliminary tests look promising. In parallel work ongoing to implement a new way to use calorimetry with SCE corrections (G. Putnam, E. Tyley).
