[Users] Meeting Reminder

[Roland Haas]

Hello all,

here are the notes of today's meeting:

The main topics were how to split the remaining work running the test 
suites for the upcoming release of the Einstein Toolkit as well as how 
to split work for MHD.

Present were Ian Hinder, Eloisa, Frank, Scott, Tanja, Roland, Yoseph, 
Christian Ott, Bruno Mundim

The initial part of the call was taken up discussing the Einstein 
Toolkit release plan and assigning machines for running test suites to 
maintainers. See http://docs.einsteintoolkit.org/et-docs/Release_Details 
for results

* Eloisa provided a status update for the failing testsuites in 
QuasiLocalMeasures, which she can make work up to issues that probably 
stem from AHFinderDirect since they differ when running on a single or 
multiple processors

* the string used to identify the release branch will be of the form 
ET_YYYY_MM (without an explicit release number). This name will 
continued to be used even if we fix a critical bug months later.

* we agreed to run the testsuites until Wednesday, then create the 
release branch, and test the release branch again on a small number of 
machines

* Ian has some testsuites for McLachlan about which there will be a 
separate discussion on the mailing list

* we will have a short call on Wednesday to sort out final issues before 
the release

Concerning MHD:

* a table outlining the split of responsibilities is at 
http://docs.einsteintoolkit.org/et-docs/MHD_implementation_details_and_discussions

* for now we will stick to the second-order polynomial approximation to 
the eigenvalues used in the HLL solver

* the MHD developers will have a discussion as to whether to have an 
explicit GRHydro::Bcom variable or to re-use HydroBase::Bvec for this 
purpose together with a grid scalar to indicate which state Bvec is in

* we agreed to create a wiki page for MHD

Yours,
Roland
