Computing and Software status, May 15, 2018¶

• Software:
  • TOF:
    • one PMT channel with hole in the ADC distribution -- needs to be blacklisted & accounted for in the reconstruction
    • Calibrations need to be improved & finalized to try improve efficiency especially for TOF2
      • VP having some issues, DR to interface with him
    • TOF review has been on hiatus, to resume

• Tracker:
  • Geometry description issue
  • Some evidence (?) that the tracker is misaligned for the scattering run period

• EMR
  • bug fix: chi2 calculation
  • bug fix: polystyrene material definition

• Geometry:
  • LH2 window material is incorrect in production geometries -- fix in hand
  • Tracker glue not correctly defined in tracker geometry -- CR has tuned the density
  • DR to push fixes to all Step IV production geometries
  • Standing: description of diffuser aperture & support materials

• MC
  • bug fix: we were not seeing delta electrons due to a bug -- fixed in MAUS trunk
  • bug fix: tracker channel/calibration look up was incorrect in MC digitizer -- fixed in trunk

• Processing:
  • Plan:
    • make a new release
    • push corrected geometries
    • run MC production
    • reprocess data

• Computing:
  • MLCR decomissioning (PF)
    • Equipment & services to be migrated
      • Target: basically done (tested and training to be finalized)
      • CDB: failover next week. One more week for the PPD slave in order to be independent from the MLCR.
      • Backups on GRID: tarballs ready for the Archivist to be moved
      • Switch off: D1 survey next week before turning most of the machines off and final Archiver tarball. PF waiting for survey before turning off IOCs and machines.
    • Computing equipment to be returned
      • QPS computer
      • Geneva computers -- onrec machines being used for local processing, so we'd like to hold on to them as long as possible

• Staffing
  • HN's grid roles: agreed that PK + student/Brunel person will take over from Henry
  • DM says he will be able to continue supporting GRID productions/processing & if support needed he can lean on Mihailo

• MAUS Paper:
  • (Finally) revised draft sent to KL, PF
