The February 2021 LArSoft Offline Leads status update were handled via email and a google document.
LArSoft – Erica Snider
LArSoft has migrated to art 3.06 as of LArSoft v09_16_00 released on Feb 4. The new version of art includes an update to root, v6_22_06a. Note that this version of root requires an additional set of ups qualifiers, e19:p383b:prof, etc.
In anticipation of the migration to the spack packaging system, we have begun work to migrate the LARSoft build to use cetmodules, which uses spack and CMake instead of cetbuildtools. cetmodules is backwards compatible with UPS, so can be used with either packaging system. There will be no impact on developers and end users when this change is introduced. More details will be provided soon once the full migration plan is completed.
There is a request to migrate to TensorFlow v2.3. The project is ready to do this, but we need people from the experiments to check that everything works as required under the new version. Only larrecodnn uses TensorFlow within core LArSoft. Both argoneutcode and dunetpc use tensorflow.
We also have a request to migrate “best effort” Ubuntu support from LTS 18 to LTS 20. This will probably require that we also migrate to gcc v9 (e20). Please send any comments you have regarding either of these changes.
DUNE – Andrew John Norman, Heidi Schellman, Tingjun Yang, Michael Kirby
We upgraded DUNE’s stack to the new art and root with very few issues. A development hdf5 reader module in dune-raw-data had used H5Cpp.h which is now removed and we are looking for alternative methods in hep_hepc but are having troubles finding a method to access file attributes. We are testing the tensorflow v2.3 product.
SBN Data/Infrastructure – Joseph Zennamo, Wesley Ketchum
We did a minor refactoring of some of our experiment code to ease further development and deployment: this has meant setting up an ‘sbnana’ that has minimal dependencies on art/LArSoft, helping us push forward on the CAFAna analysis framework development. We’re working on being ready for e20 releases ASAP, to help the Ubuntu migration to LTS20 go through faster. We’re also looking forward to the updates to the Event Reweighting presented by S. Gardiner, as that will be necessary for handing reweighting systematics in SBN sensitivity studies.
