Present were: Tanja, Roland, Ian, Yosef, Josh, Erik, Philipp

* ET fall workshop location poll settled on RIT time is likely in weeks of Oct 22nd or 29th

* required rebuilds - suspect it to be related to auto generated files - expect fix to be able to work along the lines of existing force-reconfig files - track down cause - create trac ticket

* add paragraph to "How to contribute" [1] stating the patches are the preferred method of submitting changes, but that full files are acceptable as well. In both cases listing the base revision is a requirement. - Erik will follow up on ML patch

* MHD paper status: - tests in flat space close to completion - needs some more text to describe figures - plotting scheme might need update - advection loop test stopped working recently. Will track down cause in GRHydro - Alv'en test works now that ID is available - more complex test still show problems: -- unmagnetized Bondi with c2p fixes works for some time then fails with large piled up matter inside the horizon -- Josh will look into using excision - magnetized Bondi test is likely harder - TOV tests are done, look fine, plots need to be done - collapse runs are in progress - question as to which characteristic speed to use: -- Josh suggest to use the speed of light in moving frame (see emails on list) -- Bruno is working on deriving proper expressions -- re-running these runs takes several days

* finish up MHD paper by time current grant finishes * make public announcement once MHD is well tested

* MPI will be included as external thorn * Erik has made announcement on the users list * will require changes to thorns directly using MPI * will require realclean, reconfig, build cycle

Yours, Roland
