Present were: Frank, Roland, Barry Wardell, Erik, Ian, Steve, Bruno, Peter, Josh, Philipp, Tanja, Christian
LSU server certificate: * CCT has obtained a new certificate, https should now work
ET release: * still open tickets [1] * CZ4 formalism was added to McLachlan script. It generates an extra thorn since it was found to negatively impact the current BSSN performance. * Description will be added to McLachlan documentation * include three wavetoy thorns: standard cactus, McLachlan using Kranc and McLachlan using Kranc and OpenCL * the last will be commented out by default with instructions how to enable it in the thorn list. * suggestion to have syntax in thorn lists to selectively enable thorns but no working mechanism could be proposed * will deprecate old library mechanism (ie HDF5=yes) with the exception of MPI which used by many thorns without REQUIRE statements * timing: - soft freeze date of May 14th - no additions (thorns ect.), major changes, new features - hard freeze date of May 21th - only 'important' bug fixes or documentation improvements ^--> to be decided by two maintainers - release date of May 28th. * include EinsteinExact arrangement by Barry with some documentation. Bruno and Peter volunteer to look through code. * migrate test to use new arrangement where possible for the next release
MHD paper: * want to use a single plotting package * supermongo disliked by those that do not have a license * matplotlib disliked by current supermongo users * provide matplotlib style files and samples * encourage new plots in matplotlib which are easier to update to common style than converting supermongo to matplotlib (or vice versa) * spend day near end of paper writing process to convert all plots to common style
* most tests that should work are done (ie. Balsara tests work, Komissarow do not) * TOV test works with constraint transport, fails in long runs with divergence cleaning * magnetic rotor test works with constraint transport, the LLF flux or using +/-c for the characteristic speed for the longitudinal field component * Bruno will do some characteristic structure analysis for proper speed of longitudinal field component
Yours, Roland
