h3. Infrastructure

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

** Speed improvements (*R. Bayes*)

*  Monte Carlo

** *ACTION*: Upload script feature (*R. Bayes*)

* GRID and Batch Production (C. Rogers, J. Martyniak)

** Running 0.9.7

* Documentation

* Data Structure

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)

** No more passing JSON between modules, as string conversions are expensive, only use JSON for configuration data and input / output (A. Dobbs, D. Rajaram, C. Rogers)

*** Extensive refactor work

** 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

* Beam generation excessive resource usage

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

** Consider alternative upstream beam generation code

h3. Documentation

* Finish MAUS workbook (A. Dobbs)
