yt frontend to read Carpet HDF5 files: * Sam Skillman was visiting Caltech and started to work on adding a CarpetHDF5 reader to yt (http://yt-project.org/). On the Caltech side Sherwood Richers (did the actual work) and Roland Haas were involved. Sam's reader is making good progress and the hope is to have a beta version ready by the end of the (ongoing yt) workshop. An email asking for beta testing and including download instructions will be send to users@cactuscode.org once the beta is ready. * Erik described his efforts to define an API to write/read the datasets to allow changes to the on-desk dataset * this would be well suited to yt but is currently not the mainstream data format

transition to git: * different proposals were made on how to best organize the thorns into git repositories * we will proceed with the "few repositories" option and use a layout where there is one repository per arrangement (except for exceptional cases like eg Kranc) with the ultimate goal of being able to check out directly into arrangements when possible (ie no more symbolic links) * this will include the uncontroversial arrangements CactusBase, CactusConnect as well as EinsteinEvolve * we will * we will also re-arrange some thorns that are currently (for historical reasons) in "unexpected" repositories. This includes some thorns in AEIThorns as well as eg TATPetsc * we will proceed with this right away without adapting GetComponents immediately * try to have all transitions (svn->git, single repo per arrangement) in a single release * Ian and Frank to work on conversion script from svn to git

Yours, Roland
