Hi all,

I have to teach on Mondays from 9:30AM--10:20AM (Central US time), so this semester, I will need to dial in a bit late to ET telecons (next Monday, MLK Day, is an exception).

I would like to add two items to the 2015 wish list, having to do with making it easier for IllinoisGRMHD to be used with the rest of the Toolkit:
1) Modify HydroBase so that staggered A-fields are supported. The best strategy will require that we consider how initial data thorns might be made compatible with staggered or unstaggered A-field, as well as B-field-only evolutions.
2) Incorporate staggered prolongation/restriction operators into Carpet.

they also didn't speak up)

We first talked about plans for 2015. Mentioned were:

- ET meeting in Europe, doodle poll about location and time
  - either in Italy (close to MG meeting) or Sweden (Micra)
  - either mid-July or mid-end August
- Improving timelevel handling and making Carpet more flexible wrt time
  prolongation orders etc (https://trac.einsteintoolkit.org/ticket/620)
- Dependency-based scheduling, to avoid errors and allow potential
  parallelization
- Make tests independent of number of processes, or run on the right
  number (https://trac.einsteintoolkit.org/ticket/1075,
  https://trac.einsteintoolkit.org/ticket/1230).
- Get tickets under control
  (https://trac.einsteintoolkit.org/ticket/1698)
- Adding some Hydro analysis tools used by Frank and the Parma group
- Working on Chemora, adding to the ET eventually
- Getting some more interesting single-NS initial data into the ET
- Adding Llama. Since Llama is public now, and officially released
  there would need to be a chaperon.
- Including an elliptic solver

Specific tickets/issues mentioned were
- having a type that is CCTK_INT8 by default on 64-bit platforms
  Here the consensus seems to be that using CCTK_INT as
  platform-dependent type should be ok.
- Adding a new type CCTK_INT16
- Merging the McLachlan rewrite branch
  There is a wiki page about that:
https://docs.einsteintoolkit.org/et-docs/Rewrite_McLachlan
  If nobody objects this looks like to be happening soon.
- The Jenkins Server will move to the PI. Erik and Ian will coordinate
  on that, and Frank volunteered to help.
- McLachlan will move to bitbucket. The timeframe was not fixed, but is
  expected to be "soonish".
