[Users] meeting minutes for 2025-01-09

[Roland Haas]

Present: Leo, Lucas, Maxwell, Roland, Steve, Zach

simfactory issues on anvil
==========================
* Maxwell had pointed out slowness of official files by a factor of 70
* Roland had tried to understand the root cause of the failure by
  modifying Maxwell's working files. So far is not exactly sure what is
  causing the issue
* merge changes by Maxwell in to release simfactory

LIBS issue in released Silo and PETSc
=====================================
* Roland explained issue that causes build failures when configuring
  ExternalLibraries multiple times. Fixes exist in ticket:

  but needs testing

upcoming ET possible inclusions
===============================
* NewRadX boundary should be about ready, poke Cheng-Hsin
* Z4c: want this in, Erik and Roland are champions, Steve and Peter are
  reviewers, needs testsuites
* BHaHAHA Zach is still fine-tuning things, might have paper ready soon
* CCE code should be in the works
* Roland has to contact Hayley Macpherson

release cycle
=============

Zach brought up frequency of release, Steve suggests one could extend
release cycle to 9 months in instead of 6 months. Roland mentions that
time is fairly tight in between releases, even taking a "break" of 1
months means on is running late.

Release preparation is quite a bit of work and makes it difficult to
find volunteers.

Lucas suggested reviewing the release process, trying to remove work
items that are not always needed.

Lucas suggests soliciting input and having a vote in the call, Roland
will forward the suggestion to the mailing list

Options for sequences are months of:

 8 - 5 - 2 - 11 
 9 - 6 - 3 - 12 <-- vetoed by multiples
10 - 7 - 4 -  1

tickets
=======

* https://bitbucket.org/einsteintoolkit/tickets/issues/2837 building-the-einstein-toolkit is help request

* https://bitbucket.org/einsteintoolkit/tickets/issues/2843 update-fftw3-to-3310 looks correct to Leo

* https://bitbucket.org/einsteintoolkit/tickets/issues/2840 supplement-rather-than-supercese-auto Roland reports that this helps with issues where either gsl-config or pkg-config report incorrect values

* https://bitbucket.org/einsteintoolkit/tickets/issues/2839 look-for-multiple-flavors-of-hdf5-library is useful on macOS


version tracking in ExternalLibraries
=====================================

* Zach brought up the issue if tracking and guaranteeing specific
  minimum version of libraries provided by the ExternalLibraries
* Roland points out that extracting the version number for an installed
  library is not always easy since it may involve having to parse a
  textual version string. Tools like gsl-info sometimes are lying.
* An option to test for specific versions in C code are #if and #error
  preprocessor constructs

Yours,
Roland
