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
