[Users] Meeting reminder

[Frank Loeffler]

Hi,

Here are the meeting notes of today's meeting:

1. Patches

We shortly discussed the two patches which have been proposed to be
included in the stable branch. We agreed that both patches are important
enough to be included, but need more testing before that happens.

For the GetComponents patch this would mean that it has to be tested to
work on all of the machines mentioned in the release (see
http://einsteintoolkit.org/toolkit/releases/ET_2010_06_announcement.php).

The GRHydro patch has to be tested by running all testsuites on all of
those machines and producing the same results. In addition a new
testsuite will check for the patched problem (which was not the case in
the released version), and that also has to pass everywhere. Then the
code patch and the new testsuite can enter the release branch.

2. Release tags

In order to be able to checkout a particular 'state' of the released
branch we will create tags corresponding to each state (e.g. before
applying new patches). Those are not meant to be used by regular users
(other than bug-tracking maybe).

Erik and me propose to use a tag name which starts with the branch name,
adding a string, e.g. ET_2010_06_A, ET_2010_06_1 or  ET_2010_06_01.
I propose  ET_2010_06_ follwed by an upper case letter in alphabetical
order, e.g. ET_2010_06_A. This allows for 26 tags, by which we probably
should release a new version anyway. The scheme  ET_2010_06_ plus one
digit would only allow for 9 (or 10 if you include the 0) tags, while
two digits could be mistaken to be a day.

Please comment on this scheme if you have an opinion about it. We should
come to an agreement soon to create those tags such that the two patches
mentioned earlier can be committed.


3. MHD

We didn't talk much about the MHD plans as Christian noted that most of
the necessary information is in the wiki
(http://docs.einsteintoolkit.org/et-docs/MHD_implementation_details_and_discussions)
or the mentioned paper
(http://adsabs.harvard.edu/abs/2006ApJ...637..296A) and discussions
should happen on the mailing list.

Frank
