We spent some time discussing Matt's suggestion (from two meetings ago, actually) of having all random-number related processes, such as smearing, occur in a stage before reconstruction and having the results of that stage written to disk. David pointed out that there is already a program, mcsmear that takes the hdgeant output and produces smeared hits in HDDM format, suitable for the reconstruction program. Right now only tracking is smeared but it would be straightforward to do smearing of the calorimeters as well. | We spent some time discussing Matt's suggestion (from two meetings ago, actually) of having all random-number related processes, such as smearing, occur in a stage before reconstruction and having the results of that stage written to disk.

Review of Last Meeting's Minutes
We spent some time discussing Matt's suggestion (from two meetings ago, actually) of having all random-number related processes, such as smearing, occur in a stage before reconstruction and having the results of that stage written to disk. David pointed out that there is already a program, mcsmear that takes the hdgeant output and produces smeared hits in HDDM format, suitable for the reconstruction program. Right now only tracking is smeared but it would be straightforward to do smearing of the calorimeters as well.
Announcements
Special system user account at JLab: gluex
Mark reminded us of the existence of this account. David reminded us that there are several cron jobs currently running under his personal account that would should be transferred to the gluex account.
GPU discussion next time
The often-postponed discussion of using GPU's for data analysis is tentatively planned for the next Offline Meeting. Sandy Philpott, Jie Chen,
New Magnetic Field Maps
Bug Fixes from Richard
Kalman Filter Update
Complexity Growth in HDGeant
Action Items
- Introduce calorimeter smearing into mcsmear.
- Mark will mention this to Matt.
- David will consult with Matt on how this can be done.

Notes
2. Announcements 1. Special system user account at JLab: gluex 2. GPU discussion next time 3. New magnetic field maps: David 4. Bug fixes from Richard 5. Kalman Filter update (Simon) 6. Complexity growth in hdgeant: Richard 7. Work disk: Mark 8. Software tag policy 9. Action item review
* already being done for tracking * truth points are not being smeared * mcsmear point out to Matt * root converter exists, documented in howto * conflicting answers in where-am-I root cause of no-hit, change made to gtnext, people should try, virtual divisions introduced this feature (eugene) * 2 gb switch -D needs to be included * simon, kalman filter o things look much better * richard complexity o rebuilding geant difficulty o distance of closest approach to a line, tracking, hdgeometry o back out tracking o arc correction * jim software task query (Dave) task list
