[Users] Meeting minutes for 2022-11-17

[Beyhan Karakaş]

Dear All,

Here are the minutes from today's meeting.

Present: Keith, Peter, Allen, Bruno, Zach, Yosef, Leo.

Chair: Roland
Minutes: Beyhan

ET release:


   - BBH gallery example: Allen has some issues with his cluster, still
   needs 24 hours to figure it out.
   - Canuda Scalar thorns: documentation and tests are missing. Roland
   added some documentations for the arrangement. It is too late for test
   cases, Roland will ask Miguel Zilhao to have some test cases.
   - Failures in GRHydro persists in many clusters (Sunrise, SuperMuc,
   Supermic, QueenBee, db1 and Cori):

Might be related to the intel compiler but stampede that also uses intel
compiler seems to be fine (Roland). Might depend on the version of the
compiler (Peter). Probably needs to be older than intel 19. Roland will try
and see whether it will be overcomed by using an older intel version on
QueenBee. It might also be a compiler bug. Yosef thinks he has reported
this. They were getting nans in the matter fields after the first iteration
with GRHydro (in the gallery example).

   - Release will probably not be made today due to these failures
   (Roland). Roland will  try to do it before December.


Unanswered questions


   - Issue with compiling ET on cluster [Shamim Haque]:
   http://lists.einsteintoolkit.org/pipermail/users/2022-November/008761.html

 Shamim was in contact with Erik and Roland who provided some suggestions.
It would be great to have a volunteer to answer Shahim's further questions
due to the release management of Roland.

Open tickets:

   - #2664
   <https://bitbucket.org/einsteintoolkit/tickets/issues/2664/publication-webpage-is-outdated>
   : Publication webpage is outdated, sphinxcontrib-citations may help keeping
   it updated automatically:

Suggestion and comments by Roland, Zach, Bruno, Yosef and Leo on a better
way to find which papers are using ET.

Roland could give this a try. We are not going to get all of them because
Zenodo doi's are not very often cited, people sometimes still cite original
ET papers and sometimes do not cite anything just say we used ET.

Zach: script that looks at all thorns in the ET, finding any paper that
corresponds to them would really help with this.

Bruno: It would be a good idea to use the script and manually evaluate what
the script produced.

Roland: It requires familiarity with the people in the field.

Zach suggested that it would be effective to add this to a regular item in
each call. It is similar to the unanswered question in the mailing list.

Roland: We can put it on the agenda. We could also in principle have a web
form with just a text box that arxiv links could be dropped in.

Bruno: We can just search for the paper that cites the ET paper.

Zach  has some concerns because people who use the ET do not always cite
the ET paper, they cite the thorn they use.

Yosef: Most people that use ET just mean it.


   - #2663
   <https://bitbucket.org/einsteintoolkit/tickets/issues/2663/add-an-notice-about-minimum-intel-gcc>:
   add a notice about minimum Intel / GCC version required to configure
   output:

Most of the questions about not compiling ET with intel compiler ends up
being wrong standard C++ template library.

For C++11, the error message given is not really helpful. Error message
should tell the user "you need to use at least intel 2017 and gcc 6".
(Roland)


   - #2662
   <https://bitbucket.org/einsteintoolkit/tickets/issues/2662/try-to-get-email-from-gitconfig>:
   Try to get email from ~/.gitconfig:

Something to make simfactory look for a couple places to guess a good email
address when setting up a new machine (Roland).


   - #963:
   <https://bitbucket.org/einsteintoolkit/tickets/issues/963/improve-mclachlan-accuracy>
   Improve McLachlan accuracy:


Peter gets things running on dbu. Running the standard version and trying
to rerun it with a modified version to see whether it makes a difference.
Zach would like to be informed about the difference if it exists.

Suggestion:

Zach:Would it be better for us to have a wiki page that just has tasks
anyone in the community could help (voluntarily) with (updating wiki pages
including list of publications and many other tasks which do not require a
lot of physics knowledge)?

Roland: Updated Summer student project wiki page (*
<https://docs.einsteintoolkit.org/et-docs/Summer_student_projects>) and
will add this suggestion to the next agenda.

No call for next week due to thanksgiving.

Next call (12.01):

Chair: Leo

Minutes: Bruno

Best regards,

Beyhan.
