specfem monthly zoom hour

[carltape]

The specfem team is announcing a (hopefully) monthly zoom hour for developers and users. The focus will be on coordinating development. Users are welcome to join, listen, and raise issues. If you might be interested in participating, please fill out the short google survey here
We will collect the email addresses and send zoom login details.

The first discussion is planned for Wed Nov 30th at 0800 US Pacific coast time, 1100 US Eastern time, 1700 central Europe.

[carltape]

Reminder: if interested, please sign up for the zoom hour discussion following the link at the start of this discussion. This first discussion will be informal: partly social, mostly code/org/community developments.

[danielpeter]

To put some items on our discussion list for this zoom meeting, this here would be something I'd like to go through quickly:

• upcoming releases: shall we clear out the git history before the releases or after?
• external source time functions: can we unify the 3 implementations in the 2D, 3D_Cartesian and 3D_Globe versions?
• meshing: how could we mesh urban areas, i.e., buildings, with some simple approaches?

[carltape]

Hi all, it was great to see everyone on the Nov 30th zoom. It's time to schedule the next one. We're aiming for the first Wed of every month at the following times:
Alaska 0800
US Eastern 1200
Europe 1800
KAUST 2000
For January, though, we'll take the 2nd Wednesday (January 11). The one after that will be Feb 1st. If you have not previously signed up, please do so at the link at the top of this thread; I'll email the zoom details. If you previously signed up, there's no need to do so again. Thanks for your participation.

I made a recurring event in google calendar. Hopefully this will work:

(Can someone let me know whether you see the Jan 11 and Feb 1 events?)

Hi

I am looking for figures and photos (e.g. fieldwork, workshops) from the past year for a slide loop at our AGU Business Meeting on Wednesday December 13 5:30-7:30p https://geodynamics.org/events/details/328

Please send these to me by Friday December 8 (but earlier is better)!

Thanks.

Hi All,

We just mad public the first major release for SPECFEM++, which is an effort towards unifying the suite of SPECFEM packages while providing performance portability using Kokkos. At the meeting tomorrow I plan to present a few slides and demo of the package and respond to any questions you have. Please try out the code.

Repo link: https://github.com/PrincetonUniversity/SPECFEMPP
Documentation Link: http://specfem2d-kokkos.rtfd.io/

Hope to see everyone tomorrow.

[Rohit-Kakodkar]

Slides from today:
SPECFEM++_v_0_1_0.pptx

If you have any questions or would like a featured added to SPECFEM++ please feel free to reach out to me at [email protected] or post a issue on the SPECFEMPP github page.

Thanks,
Rohit

Hi SPECFEM community, the next SPECFEM Zoom hour will be this Wednesday, April 3rd, and I would like to spend some of our meeting discussing the upcoming SPECFEM Developers Workshop (#1664), taking place both in-person and on Zoom April 30th at SSA2024.

Please attend the Zoom this Wednesday and join in on discussing a potential agenda, where I hope to get some input on:

1. How can we make this a useful workshop for all?
2. What is the best use of our limited time, e.g., lightning talks, open discussion, mini-hackathon?
3. Are there any goals we want to accomplish?

Reminder that the workshop is hybrid and registration is open, please sign up if you haven't: https://geodynamics.org/events/details/343

Hope to see you all this Wednesday for the monthly zoom! And at the workshop April 30th!

I'm hoping to discuss our implementation of wavefield injection, with more details than my SPECFEM workshop presentation. Currently the code can be accessed at https://github.com/tianshi-liu/specfem3D-injection.
