  • The collaboration board was meeting in parallel, which severely limited the attendance.
  • Nathan made progress with the JANA2 port. A few test experiments with streaming readout are planned in the near future.
  • Mark is working on a build on Fedora 37. The native gcc version 12.2.1 is uncovering various problems, one of them related to the C++17 standard in evio was fixed [3].
  • We discussed the start counter orientation and mapping problem

Action Items

  • Provide Centos7.9 container with gxrun/gxshell (Peter)
  • Discuss strategy for upgrade of online machines with computing center, possibly install singularity (Alex)
  • Investigate DSelector problem on RHEL8/Rocky8 (all)
  • Investigate low memory efficiency for halld-osg jobs: 8core/8GB (Peter/Thomas)

Sean's projects:

  • Deprecate HistogramTools.h
  • Separate out halld_amp from halld_sim and support pure analysis builds in build_scripts

Notes from the Sci/OPS Meeting

  • slides
  • will be the next login note, equivalent to hallgw, no separation
  • Rocky8 still default, but CERN/Fermilab is moving to Alma8/9. Sci/OPS would like to go to Rocky9 as well, but difference between Rocky (company) and Alma (non-profit) is mostly political.
