* next ET Release [SB, YZ, RH]
https://docs.einsteintoolkit.org/et-docs/Release_Details
[Steve is not present.] No specific updates. Roland, we do need to "poke" the various items. And look for gallery testers. Yosef, Kuibit reviewer has no news. Roland, RePriMand reviewer also no news.
* "hack-a-thon" to clean up tickets, documentation, web pages
Yosef, Put on the mailing list for scheduling. Roland, Go through the tickets and look for easier or harder tickets and go from there. Go through and fix warnings. Roland, would make a list; Ian hinder tried to classify as urgent and not so urgent. Code authors could go through the tickets. Some older components in the toolkit might not have good documentation.
[https://www.einsteintoolkit.org/tools/unanswered.php unanswered question on mailing list]
Aug 13, THC thorn. Roland, we have kept hands off because either a THC or Kadath question, or both, not in the toolkit. So not for us.
Sep 1, ET and recent intel compilers. Steve seems to be handling this (last exchange 25 Aug), but we should still document the problem with the compiler and if one or other is the correct one. Intel compilers on Bayou system at LSU. Peter has access to intel 21 machines and can try something, would test suite work? Likely need a BNS parameter file. Yosef, have older intel at RIT cluster. Atul, there is the BNS gallery example to use.

No discussion...lots of them.
[https://bitbucket.org/einsteintoolkit/tickets/issues?status=new&status=o... tickets ready for review]
#963, improve McLachlan accuracy. Peter will take a look at this.
#2568, Roland can make the messages more clear, or document.
#2570, update MPI tarball. Roland two things changed here, update the tarball, 4.0.1 current version fails to compile on USX (infiniband, and low level support UCT), 4.0.6 works with both versions. This happened on Deep Bayou to Roland when installing own MPI. Other change in the Pull Request, make MPI link against all libraries that HWLOC uses, udev (?) and NUMA. Usually works on systems with dynamic linking but on static it can fail.
#2563, isfinite() supersedes finite(). Helvi, a problem on the new Macs with the M1 chip. Roland will apply it today unless someone seriously objects.
#332, Cactus and environment vars. No discussion.
#2364, avoid HDF5 files opening many times. It is an enhancement. Roland, put this in for Blue Waters where filesystem was slow. Ticket is lingering in case anyone wants it/needs it.

Gabriele B, hack-a-thon suggestion, would be useful to have more param files that cover more cases; there are so many features in the ET. Did not find them earlier because no param files showing them. Helvi, keep in mind they should be consistent on the web site or wherever we keep them.
Roland, more examples of param files, we might want to turn some into gallery examples to keep them up-to-date, keep them from "aging out" and no longer working with the toolkit.
Bill, we might also considered a place that is not so well curated, a "community contributed" site, where users can upload parameters files, results, and some comments on when and how it ran. A user at your own risk kind of site. Seems we would get many more param files, but there would be overlaps, lack of quality control, etc, etc.
Helvi W, been asked to co-organize a workshop for numerical relativity in Aug 2022, with SpEC, with David Radice, Leo Stein, probably at Brown university. Mix of few days of hack-a-thon/tutorials, discussions, and working together. It is an ICERM program, another three weeks for computational gravity during the semester. Recall, ICERM fall 2020 was about Computational Relativity, https://icerm.brown.edu/programs/sp-f20/ .
