← All weekly reports

Summary for Hall-B

• Fixes for FT sensitivity in OFF configurations
• Fixes for RGE run-based workflow
• Portal improvements: priorities and estimates for job completions
• Addressed pelican bug (half transferred files)
• Updated DDVCS geometry/gcards for high luminosity proposal

GEMC

• Main Branch:
  • RGE FT was in the OFF configuration, but still active. Made calorimeter and hodoscope components passive across the FT-OFF periods, verifying all geometries.
  • User Uditha confirmed vertex improvements due to the solid target implemented in clas12-config under ‘runs’
  • Merged Raffaella’a modifications for DDVCS
• Meson branch (synced with main):
  • Meson build system presented the software meeting
  • Incorporated feedback to not install subprojects; opt-in via dedicated options. This needs a CCDB patch (implemented locally)
  • HIPO tests opt-in via dedicated options, by default only CLAS12 tests are done.
  • Fixed a broken workflow by installing the required geometry in the experiments directory
  • Improved static libraries build across the supported platforms, resolving linker-flag on Linux and macOS.
  • Added flexible magnetic field-map handling: an option to reuse an existing field-maps directory and a switch to the magfield repo that fails clearly on unresolved assets. This needs magfield MR approved.
  • Propagated the FT-off sensitivity change and all other changes to the meson branch.

OSG

• Uograded the portal’s total and per user completion-time estimates
• Corrected edge cases for users with and without active submissions.
• Steady at ~11K concurrent jobs with a notably lower hold rate than prior days. OSG staff reported pelican sites fixes
• Fixed stalled pelican uploads back to JLab so that timeouts are now errors rather than false success.
• Working on Technical note for the new OSG software and portal
• Offending user (dominating in August) contacted about phase space optimization. All their jobs are stopped / deleted.

Geant4

• Finalized registration, travel, and lodging arrangements for the Geant4 school.
• g4home link to new tutorial updated
• g4home links added: installation/examples.
• Installation: use of g4install.

GEMC3

• Fixed skipped deployments caused by shared concurrency, validated the workflow against test commits, and updated the accompanying documentation.
• Testing multithreaded scaling

Homepage

• Built an automated end-of-week pipeline that condenses daily notes into a toned-down public weekly report, published as a month-grouped directory index on a scheduled basis.

Other

• Improved the work-journal process by restoring entries as one-line summaries and clarifying the brevity convention.
