* SPEC benchmark contribution
[https://bitbucket.org/einsteintoolkit/tickets/issues/2470 task] [RH, SB]
No updates

** Binary neutron star lectures / tutorials at summer school (ID theory
, ID generation, ID usage) [RH]

ID Theory:
Antonios: Discussing the math behind the ID.
Theoretical point of view, 2x45 adequate to cover BNS ID. Provided 3+1
decomposition. Antonios taught it before.

ID generation, ID usage
Maria, Bruno and Atul :
Atul: Should there be a tutorial on download and setup for LORENE? If
yes, should we bother with LORENE2 on ET?
Bruno: Lorene takes too much time to download.
Bill: Do we know the machines available for the meeting?
Roland: Yes, 40cores ...
?? : Compile time depends on the EOS
Bruno: Should do atleast Single ToV maybe
Roland : Should atleast show the BNS par file
Erik : A coarse setup might speed things up
Bruno : All easiest done with Lorene1 (i.e. LORENE from website)
Roland : LORENE2 compiles code for BNS

Maria: Don't know LORENE2. Will provide a library of hybrid data. Maybe
make a Jupyter notebook. Has run all of hybrid data by Josh and more.

Best of both, freely available and as easily usable. Probably on a
Jupyter notebook.

Bruno: Should do Piecewise Polytropic EoS
Give tables to the students to try later.

Two different formats : CompOSE[https://compose.obspm.fr/home] and
Internal Lorene format.
Eos_tables cant be read by GRHydro.

Erik: Precompiled data.

Maria: Read and visualize ID maybe?
Bill: VisIt and all take more time
??: Do we have visualization talks?
Roland: Very little space-time left in this ET meeting.

Roland: How much time ultimately needed for LORENE?
Bruno: 2x45 should be fine: 1x for generating + 1x for running.
Maria : 45 mins for ID development + 25-30 mins for running ?

Erik : maybe make some 1 hr slots and some 1/2 hr slots.


* ET 2021 NA summer school date selection email

[RH]

Roland : Dates options for meeting are July 26-30 or August 16-20. Most
likely going to be July 26-30.


* Release planning [ZE]

Zach: Tickets added to POWER submitted by Gabriele. @RH can these be
added before freeze?

Roland: MH has more suggestions.. Two punctures..
Some of the bug fixes would most likely get fixed.

Zach: Can the most essential bug fixes be done in time?
Roland: Likely.

May 14th as feature freeze.

** release testsuite status
[http://einsteintoolkit.org/testsuite_results/index.php]

Zach: Compiling everywhere. Some testsuite failures related to Con2Prim
.
How many failures is too many?

Erik People want to know if the failed test is somewhat explainable.

Maria: Erik’s script for BBH runs well.

Bill: Is the QBC test somewhat concerning?
Roland: Grey ones (QBC) have not been tested for some time.

** proposal to enable presync in gallery parfiles [RH]

** Gallery examples:

Zach: Start early. Prepare systems ahead of time. Update the ticket
after feature freeze.

Bill : Update the graphics and “last tested” dates.

*** BBH [SB]

*** BNS [AK]

*** Multipatch [BG]

** bugs of severity major or worse [https://bitbucket.org/einsteintoolk
it/tickets/issues?kind=bug&priority=major&priority=blocker&priority=cri
tical&status=new&status=open]

Roland : Major means needs to be fixed before the next release.
Critical doesn’t compile. Blocker means can't do science.

Zach: Very old “Major” tickets might not be as critical.

Roland: Milestone implies the bug needs to be fixed before that date.
Major tickets without milestones may end up not getting fixed due to
not being prioritized.

More discussion about classification of tickets Critical, Blocker,
Major, Minor, Trivial.

** all open tickets [https://bitbucket.org/einsteintoolkit/tickets/issu
es?milestone=ET_2021_05&status=open&status=new] flagged for the next
release

* ET Jenkins replacement demo
[https://mojamil.github.io/einsteintoolkit ] [RH]
http://lists.einsteintoolkit.org/pipermail/users/2021-April/007924.html

Roland : Github actions based. Current machines will shut down in
October. Want atleast a minimum working set on Github.
