[Users] Meeting minutes for 2024-05-09

[Lucas Timotheo Sanches]

Present: Steven R Brandt, Kai, Keith Dow, Samuel Cupp, Peter Diener,
Zachariah Etienne, Roland Hass, Leo Werneck

* We had a new member, Kai's, to join in the meeting. Kai is a
German software engineer creating a Game Engine. He wants to
model GR physics with his engine and is interested in learning
GR / NR.

* US ET Workshop June 3-7 [SB]
  Steve says that the workshop is "in pretty good shape, in
  terms of the number of speakers".

  Currently, there are too many funding requests to attend
  the workshop and too little money to fulfill these requests.
  There may be support from CCT for paying for the meals of
  participants. There is some spare money from the Spec
  benchmarks that may be used for the workshop.

  Steve expressed that van drivers for the Wednesday LIGO tour
  are needed.

  Philipp Moesta has announced the European ETK workshop in Amsterdam.

* ET release timeline [SB]
  The release timeline is def. going to slip.

  The new target is the second week in June.

  Roland urged that codes from personal git repositories be moved into
  the ETK organization repository.

  Seteve urged to contact the NewRadX devs to move their repo. The need
  to move CarpetX was pointed out as well. Roland will make sure that
  happens.

  Roland brought up that gallery example runners are needed. The gallery
  examples need to be done before the new release deadline.

  Steve has volunteered to take BNs example.

  Deborah Ferguson volunteered for BBHs example.

  Roland has a student coming in June and will ask him for a TOV example.

  Lucas volunteered to run the MultiPatch example.

* contributions (champion, reviewer)
  ** MultipoleX (Lucas, Roland): Steve wants to figure a way out to
     make that work with Roland.

  ** NewRadX (Alex, Liwei and Jay): Jay is reviewing the thorn.

  ** Z4c (Erik, Steve): Dead. Not present in this release. Not enough
     time for it to get ready. Has no tests.

  ** GRHayL-based IllinoisGRMHD (Sam, Lorenzo): On track.

  ** Baikal(Vacuum) using NRPy 2.0 (Sam, Terrence): On track.

  ** GRHayLHD(X) updated to include tabulated EOS (Sam, Terrence): On
     track.

* Unanswered question on the mailing list

  The issue with npernode value in MPI (Shamim Haque 1910511): Steve
  the problem is more or less solved.

* Open tickets sorted by update time
  SyntaxWarnings Raised During Build Process with Python 3.12: Roland
  requested changes to the simfactory ini file reader.

  TACC Stampede3-skx Compilation Failing
  [-Wincompatible-function-pointer-type]: Remove the restrict keyword
  from the thorn. Roland will do it. At some point, restrict needs to
  be restored, because in Fortran, a restrict is a "default".

  ET webserver no longer sends email: Closed.

  Add sorting capability to the manifest: Steve made a sorter to solve
  this problem, which could be used or not.

* Tickets ready for review

  SyntaxWarnings Raised During Build Process with Python 3.12: See
  above. Roland will investigate why the ticket has not yet been
  closed since he fixed the problem.

  Improve McLachlan accuracy: Peter and Zach have No updates yet,
  but they scheduled a meeting to work on this.

  zlib: also use pkg-config when searching for installed versions:
  Solved by Roland.

  Issues link against Kadath Thorns and Intel MKL due to link
  ordering: Sam wants/needs to do more stuff before it is closed.
  Maybe poke him.

* Talking to Kai about what he wants/ what he got from the meeting.

* Peter suggests Kai studying perturbations for particle motion
