* Before agenda items? (like quick help questions, etc)

None

* SPEC benchmark contribution 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2470 task] [RH, SB]

Steve, Roland asked SPEC how things are going, they outlined what more 
they want from
us.  They want to be able adjust workload to keep a 40 core Haswell 
machine busy for
many minutes.  They could integrate Cactus fine, adjust config.h for 
various platforms
...they will do that.  When testing is done, will start on step 2 
proposal, workload is
step 3.  Their goal is for Serial max memory 1.8 GB and run for 8 min, 
for Parallel 40
threads 8 GB and 10 mins.  They are asking for advice on adjusting 
workloads.
Nothing is urgent but there are things to be done.  See above ticket, #2470.

* Release Planning [ZE]

(Hendrik) Lorentz is the release name.

Zach, It is coming along.  Release Announcement draft has been shared among
maintainers, 
https://docs.einsteintoolkit.org/et-docs/ET_2021_05_release_announcement .
Simfactory should work with Python 2 or 3, compatible with Python 3 
stated in the
announcement.  List of changes since last release should be double 
checked by
everyone.

Steve, Maintainers database exists inside the repo.  Zach sees 
developers.txt, and
scripts to turn that into other formats.  Developers.py creates HTML, 
and Zenodo.py
will also read developers.txt .  Release helpers should go into this 
file for the current
release and taken out for next release.  Handling this file should be in 
the Release
Planning, etc.  See http://einsteintoolkit.org/developers.html and
https://bitbucket.org/einsteintoolkit/www/src/master/developers.txt .

Zach has been updating the Release Planning documentation
https://docs.einsteintoolkit.org/et-docs/Release_Process .  One advice 
is to word wrap
at line 72 for the email formatting, he added an online tool to do that.

Branches created tomorrow, so any minor changes have to happen today.

Do we use SVN?  Steve, maybe.  Roland, we do not have any Subversion repos
anymore, some checkout function does use them.

Atul, Zenodo ticket #2524 should be addressed
https://bitbucket.org/einsteintoolkit/tickets/issues/2524/zenodo-page-shows-only-2015-et-grants 
.
Zach, Zenodo may not be updated by May 31st.  But the DOI from them is 
part of the
bibtex key we ask people to cite.  Nice if there, but not checked out 
for new release,
so can be updated later.

Zach, Will edit the main ET page, http://einsteintoolkit.org/index.html 
.  Remove the
ICERM announcement, keep North American Workshop, and Release Announcement
in the center.

If you are part of the release team, gallery example checkers included, 
double check
your names at 
https://bitbucket.org/einsteintoolkit/www/src/master/developers.txt .

** Gallery Examples [ZE]

*** 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2172/test-binary-black-hole-gw150914-example 
BBH] [SB]

Steve, it runs and finished a bit early, so will run it to the end---ran 
out of time.
Working with Kuibit to generate the plots vs Mathematica. Waveforms and 
trajectories
look fine.

*** 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2175/test-single-stable-neutron-star-example 
TOV] [PD]

Peter, re-ran it last night and still works fine.  Will update web pages 
tomorrow/Friday.

*** 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2174/test-multi-patch-scalar-wave-equation 
Multipatch] [BG]

Bill, Runs fine with and without Presync.  Updated the Bitbucket / web 
pages, had to
remind myself how to upload the tarball, what credentials to use (create 
a APP key on
bitbucket but use my username not SSO email, go figure).

*** 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2176/test-binary-neutron-star-example 
BNS] [AK],

Atul, Done but not finished the Bitbucket updates.

*** 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2173/test-poisson-equation-example 
Poisson equation] [MG]

Miguel, finished the test and it was fine.  Upload the tarballs and 
files, but need to
update the links on the web page.

Atul, We should re-run the examples again with the new Release...in June 
sometime.

** POWER 
[https://bitbucket.org/einsteintoolkit/tickets/issues/2413/include-power-code-to-extrapolate 
status] [RH]

Maria, did look over the documentation for it and wrote something on 
Bitbucket and
Roland should check it out.  Roland, some items in the ticket #2413 are 
more ET
related and not Power related---will clarify in the documentation.  
Maria, Power works
with BBH but not so easy with BNS.  Roland, you can run it with BNS but 
need to specify
more items.  Atul, add in documentation how to change the frequency with 
masses,
and about quasi-local measure.  Roland, want to avoid too much 
information for
running ET in the Power documentation.

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

Steve, #2533 is not fixed yet.  If two ActiveThorns that is the problem, 
but need better
messaging.
https://bitbucket.org/einsteintoolkit/tickets/issues/2533/activethorns-not-accepted-in-parameter

Yosef, #2534 Mol never worked well with Grid Arrays, but had a code that 
did work and
it currently does not.  Has not worked with 2020 releases, did in the 
2019.  Compile
issues had missing header and maybe Presync problem.  Steve, if we do 
fix it we need
to add a test for this issue/problem so we do not break it again.

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

#2526 is not a blocker and will not be ready by the release.
https://bitbucket.org/einsteintoolkit/tickets/issues/2526/mclachlan-has-incorrect-read-declarations

#2469 Leonardo, I iwll push hard on this today.
https://bitbucket.org/einsteintoolkit/tickets/issues/2469/none-of-the-thorns-in

#2488 Atul, has a minor tag so not critical right now.

Zach, Last commits should be minor and not change functionality and 
should happen today.
Will work with Steve and Roland on the Zenodo, etc.  But please read the 
Release
Announcement soon, want to finish it.

Bill, we should mark the tickets (which are listed as Tasks and not 
Tickets) for the gallery
examples as resolved when you are through with them.  They will be 
re-opened and
re-assigned for the next release.

[https://www.einsteintoolkit.org/tools/unanswered.php unanswered 
question on mailing list]

Seem to be handled.

open tickets sorted by update time]

#2530, Roland has some ideas to fix it, not high priority and will not 
do anything before
the release to avoid breaking anything.
https://bitbucket.org/einsteintoolkit/tickets/issues/2530/thorn-vectors-fails-to-compile-using-gcc

[https://bitbucket.org/einsteintoolkit/tickets/issues?status=new&status=open&sort=-updated_on&q=Please%20review 
tickets ready for review]

Six tickets most still need reviewers.  Please volunteer.

#963, Peter, did look at it.  It is a patch to an old version of 
McLachlan that is no longer
current.  Has to wait until after the release.
