h3. Infrastructure

* Geometry/MC (S. Ricciardi, R. Bayes)

** *ACTION*: Make current beamline geometry available in CDB (*R. Bayes*)

* Need C++ Reducer example (*A. Dobbs*)

* Documentation

h3. Online

* Online reconstruction (A. Dobbs)

* Have prototype GUI and prototype ROOT-based document DB to replace maus-web-app and django #1312 (C. Rogers)

* Software On Call (A. Dobbs)

** http://micewww.pp.rl.ac.uk/projects/maus/wiki/Software_on-call (SOC wiki)

h3. Performance

* Speed improvements

** Fix memory leaks - preventing GRID runnning (A. Dobbs, D. Rajaram, C. Rogers)

** -YK proposes parallelising MAUS with C++11 multi-threading, at the mapper level, see #1638 (A. Dobbs, D. Rajaram, C. Rogers, Y. Karadzhov)-

*** -Extensive refactor work-

*** Current MAUS speedup is satisfactory. Can revisit, if any speed issues with MC.

* Beam generation excessive resource usage

** Query analysis group requirements (in particular how many G4BL beams we need)

** Consider alternative upstream beam generation code

h3. Tools

* Add V. Blackmore event visualiser to MAUS

h3. Detectors

* Detector Integration

** DR asks that detectors provide a simple yes/no flag to denote 'analyzability' of a run.

** DR will produce one for TOFs. 

** PK agrees that a high-level yes no should be easy to get from trackers based on #spacepoints/digits [ or something of that sort ]

** Need to get this done so that Janusz can implement table in CDB & test on preprod before rolling out

* KL

* Ckov

* EMR

* Tracker

** PK: has generated plots [ Tracker efficiencies based on slab hits in TOF1/TOF2 --> ~98-99% for t1, ~85% for T2 up to 98 after Ed's calibration ] which Ed thinks are useful. 

** *ACTION*: need to get the plots into MAUS. PK has asked MU about getting them into MAUS. [  ]

** PK: Tracker efficiency map may need to be folded into MC if there are reasons to believe the fiducial-dependent (in)efficiencies may affect emittance measurements

** Ed & CH  have updated calibration & maps. In the trunk.

** CH has added a calibration/mapping uploader/downloader to MAUS. The track reconstruction code does not automatically download the calibrations from CDB. But this can be done [ similar to what's done for TOF/KL/DAQ ]

** *ACTION*: Config cards: Finalize tracker reco cards & move them to ConfigurationDefaults

*** Currently track reconstruction is not set to handle case where one magnet is on and other is off. Since we'll likely have more than one data-set with this configuration, can we modify code to handle it natively? [ instead of having to process twice, once with Helical on and once with Helical off ]

* TOF

h3. Global Reconstruction

** JG: de/dX implementation in RK is done. Currently testing.

** CP & JG report issues with running Global reducers

*** CP: issue when setting header_and_footer_mode to "dont_append". CR will chase this. Could be a SWIG issue. CP to remove swig .i file and see if that sorts it out.

*** JG: cannot run reducer in conjunction with mappers. DR has been running mappers + tof calib an plot reducers. JG to check if this is also a swig issue. If not, raise issue.

h3. Unpacking

h3. Batch Reconstruction

** MC processing almost there. Code-side is OK. CDB-side: RB to upload cooling channel tags to production DB [ has been tested on preprod. ]. Plan is to wait for new MAUS release and try running batch MC and grid next week.

h3. Infrastructure

* Geometry

** June & July geometries are in CDB: 69, 70

** RB to verify that "current" geometry points to ID 70

* MC

* G4BL

* Other

h3. Performance

h3. Tools

h3. Miscellaneous

* PK to check tracker schedule and update by end of the week

* JG to update Global schedule this week.
