Carpet workshop recap:

* refluxing is implemented (for multiple processors) but needs more 
testing in production sized runs
** it requires Carpet support as well as an external refluxing thorn
** refluxing adds constraints to how the grid is laid out that have to 
be enforced by the regridding thorn
** CarpetRegrid2 adheres to these constraints
** it now works on multiple processors
* MHD is largely implemented, implemented are HLL, Con2Prim, Prim2COn, 
PPM, still needed is Con2Prim_Polytype. It passes simple shocktube tests 
but requires more testing.
* the unused grid points mask is implemented but it turns out it is only 
non-empty if the grids are very large
* we know what to do to support higher numbers of refinement levels, but 
implementing it requires carefully going through the code
* the code to not output 3d buffer zones is written but not well tested, 
it will be committed to the Mercurial version
* I/O
** Nirvana (N5) library has been written and provides a high level 
interface to I/O similar to Werner Bengers F5 format
** ADIOS 2.0 has been made public, and now supports AMR, so it might be 
a useful backend for N5
** Christian Reiswig has added code to create subdirectories for the 
output files to avoid having tens of thousands of files in a single 
directory
* Ian Hinder has written a timer class and a Mathematica notebook to 
visualize the output of the class

Citation policy:

* thorn authors are free to specify which citations they would like to 
see, the Toolkit does not mandate any particular requirements (or lack of)
* files listing both the compulsory and recommended citations will be 
part of the Einstein Toolkit checkout (possibly auto-generated form the 
thorn sources)

We will have a presentation on simfactory during the next (or soon 
after) phone conference.

Yours,
Roland
