[Users] Meeting minutes for 2025-06-05`

[Steven Brandt]

June 5, 2025
Present: Roland, Steve, Lucas, Calil, Johnny, Zach, Bill Gabella, Deborah

Calil called in with memory problems when running in Unigrid. Hopefully, 
they will create a ticket.

Lessons Learned from the Release:
* Issues with creating release branches. Only Roland and Steve can 
really do it.
* Need to start testing earlier. We didn't discover some problems until 
after the release.
* Somehow reduce the work for the release.

Gallery Examples:
* Zach and BBH, had trouble running it.
* Steve Poisson Gallery Example
* Axidilaton - Deborah Ferguson (ran it)

External libraries are often a problem:
* HDF5 build failures. Fedora now works, but possibly for the wrong 
reasons. Should be a ticket.
* SILO tries to identify the machine, and has a default for "localhost." 
Need to disable this test for known clusters.
* Add a Spack recipe?

ET Summer School
* Most speakers are confirmed
* Amount of people registered will fit in the room
* 30 participants
* Online attendees should register
* Remote participants will happen via zoom

Update on Bahahah - Quickly drafted a documentation.tex based on AI 
(Gemini 2.5 Pro), then edited.

Status of NRPy Elliptic ID solver. Currently, a two punctures solver. 
Does not allow for refinement. High mass ratios are hard.

Tickets:
2873 - Disable hard-coded compiler options in Silo
Proposal: CCTK_ASSERT() macro which calles CCTK_Error on failure
2872 - gcc 15 is causing issues because it is stricter.
