Software & Computing Issues¶
Software & Computing Issues:
- Software
- Tracker:
- Inefficiency at low pt: PK & AD to look at it
- NaN bug: bug identified, pending fix in MAUS trunk
- Charge reconstruction bug: has been flagged, tracker group to investigate
- TOF:
- Discrepancy between TOF & tracker of ~100 ps: Scott Wilbur starting to investigate by looking at TOF0-TOF1 path-length effect
- Global:
- TRef issue in data structure holding back Global track matching from going into production processing. This has now been fixed -- need some performance tests before going into production.
- Field handling
- Need to account for PRY effect in MAUS fields -- cumbersome (no manpower) to generate OPERA maps for each current setting
- Correction factors (at 4T) received from HW/JP
- Need to run some sample reconstruction with different scale factors to test
- MC:
- G4BL generation is bottle neck
- FD to look at this next
- Consider TOF0 as G4BL-MAUS handoff point -- needs to be tested by pushing through both G4BL & MAUS and comparing
- FD to provide G4BL generation scripts, DM will run them on GRID
- Also need some versioning/book-keeping cleanup of G4BL inputs
- Tracker:
- Infrastructure
Working on creating a DB table to hold alignment corrections to surveyed geometry(#1817)- Table & associated software API have been created (JM), opened to developers, RB is testing
- corrections will be applied at geometry download time, transparent for end-user
- Reconstruction quality table has been created along with API (JM)
- Reco flags will come from a post-processing job
- 4 bits for each detector (count 11 detectors including RFs from Cooling Demo)
- DR developing post-processing & quality extraction infrastructure
- Reco flags will come from a post-processing job
- Data reprocessing
- Data to be re-processed with next MAUS release once tracker bugs are fixed
- may have Global in this iteration as well
- Will like to have alignment corrections coming from the CDB table (above) for this round of processing
- RB & JM away, so this might not converge for this release, but..
- Data to be re-processed with next MAUS release once tracker bugs are fixed
