[Mpi-forum] Virtual MPI forum meeting June 14, 2023 / Vote announcement for the July 2023 meeting of the MPI Forum

Wed Jun 14 09:32:08 CDT 2023

Hi Rolf, 

No problem - I added a meeting slot for next week.

@All: as for this week, let's meet anyway and go over the pending items - this may be a short meeting, though, as not much seems to be left at this point - thanks to Wesley, here is the current overview:

https://github.com/orgs/mpi-forum/projects/1/views/9

The meeting is as usual at 10am US CT and the Zoom link is linked from:

Thanks!

Martin

Dear all, 

I just saw that I have a hard conflict today and that I cannot come to the virtual meeting today.
My apologies.

Therefore, I must skip my topics #710/PR823 and #676/PR825 to next week.
I hope that any discussions can already be resolved during this weeek.
If you are interested, please look at the commented pdf files.

@Martin, please can you add a virtual meeting for both readings on June 21, 2023.

Kind regards
Rolf
